TECHNICAL TASK Development of a Digital Signage system for a network of advertising screens 1. General description of the systemThe system is designed for remote management of media content (video, images) on a network of televisions running Android TV. Architecture:Backend / Control Panel (Admin Panel): PHP (Laravel / Yii2 or pure PHP) + MySQL.Frontend (Player on TV): HTML5 / JavaScript (Single Page Application), which runs on TV in full-screen mode via the Fully Kiosk Browser app.2. Functional requirements: Control Panel (Admin Panel on PHP)2.1. Screen (Television) ManagementAbility to add/remove screens in the system.Each screen is assigned: Name (geo-point), unique ID (device_token), and status (Online/Offline).Monitoring (Ping): Displaying the TV status in real-time. If the TV has not sent requests for more than 5 minutes, color its status red (Offline). 2.2. Content Management (Media Library)Uploading files (video, images) to the server.Deleting files (with automatic deletion of the physical file from the server).Ability to view (and modify) on which screens each individual media file is broadcasted.Setting the playback order of files. 2.3. Server API (for communication with TV)Implement REST API (JSON):POST /api/ping — receives its ID from the TV, records the last activity time (for Online status), and returns the current playlist version.GET /api/file/device_token — returns the current JSON array with links to media files, their order, and display time settings.3. Functional requirements: Client Player (HTML5/JS on TV)The player is a web page that is opened on the TV. The main task of the client is autonomy.3.1. Caching and Synchronization (Offline Operation)Upon startup, the player requests the playlist via the API.Local Storage: All files from the playlist (video/images) must be loaded into the internal memory of the browser (using Cache API or IndexedDB). Streaming (playing directly from the internet) is prohibited.Synchronization: If new content is added on the server, the player loads it in the background without interrupting the current display. After loading is complete, it adds it to the broadcast. If content is deleted on the server, the player must remove it from the local TV cache to avoid filling the device's memory.Offline Mode: In the complete absence of the internet, the player endlessly loops the last successfully loaded playlist. 3.2. Playback and RotationCyclic playback of content and according to the order set in the admin panel.For images, the display duration in seconds must be set (default 10 sec).Transitions between videos must be smooth, without black screens and noticeable page reloads. 3.3. Logging and Error Control (Failure Protection)Handling Corrupted Files: If a video file is corrupted and cannot be played, the player must skip it and turn on the next one in order, rather than hanging on a black screen.Show Logs (Analytics): The player must record in local memory the fact of each successful playback of a video. When the internet is available, this data is sent in batches to the server (POST /api/logs), so that statistics can be viewed in the admin panel: "Video A on TV #3 was shown 450 times in a day and 2365 times in total".4. Optimization Requirements for Android TVThe player interface must not contain any control elements (cursors, scroll bars, buttons). Only clean content on the full screen.JS code must be optimized for memory (timely clearing unused DOM elements and object URLs), as budget televisions have strict limitations on RAM and may crash the tab due to memory leaks after 12-24 hours of continuous operation.

It is necessary to migrate the Opencart online store from PHP 7.4 to PHP 8.x. Currently, the core version is 3.0.3.8. We read that most likely the core will also need to be migrated to version 4.0 and there shouldn't be many difficulties... The functionality is mostly custom, and there are also Simple, OCFilter, Nova Poshta. We are waiting for recommendations and an approximate price. Ideally, someone who has already done similar work.

It is necessary to perform the update, transfer, and configuration of Laravel projects to a new server, ensuring stable operation, security, protection against exploits, and correct functioning of all services after migration. 1. Main tasks Prepare the new server for operation. Transfer project files, databases, configurations, and cron jobs. Update server software. Configure a secure environment for Laravel. Check compatibility of PHP, Laravel, Composer packages, and dependencies. Ensure protection against known exploits, malicious requests, and unauthorized access. Set up SSL certificates. Check the functionality of the websites after the transfer. 2. Transfer of Laravel projects For each project, it is necessary to: Transfer project files. Transfer the database. Transfer the .env configuration. Set directory access permissions: storage bootstrap/cache Check functionality: homepage; admin panel; authorization; forms; API; file uploads; email sending; cron jobs; queue workers.3. Security and protection It is necessary to implement basic and application-level protection: close root access via SSH; configure SSH access only via keys; change the default SSH port if necessary; configure the firewall; allow only necessary ports; install Fail2Ban; hide service versions of Nginx/Apache/PHP; restrict access to .env, .git, backup files, log files; set correct file permissions; check projects for malicious files; check Composer packages for known vulnerabilities; update dependencies if it does not break functionality; configure protection against SQL injection, XSS, CSRF, and path traversal; check the correctness of Laravel APP_ENV and APP_DEBUG; set APP_DEBUG=false in production; configure rate limiting for critical endpoints; check access to storage/uploads; configure protection against PHP execution in upload directories; check access rights to admin panels. 4. SSL and domains It is necessary to: Install SSL certificates. Configure automatic SSL renewal. Enable redirect from HTTP to HTTPS. Check the correct operation of websites via HTTPS. 5. Backup It is necessary to configure backup: project files; databases; .env files; uploaded media; cron configurations; Nginx/Apache configurations. Backup should be performed automatically on a schedule. It is preferable to store copies separately from the main server. 6. Post-transfer verification After migration, it is necessary to check: absence of 500/403/404 errors; absence of critical errors in Laravel logs. 9. Result of execution After the work is completed, there should be: Laravel projects successfully transferred to the new server; websites are functioning stably; SSL is configured; the server is protected with basic security settings; access to critical files is restricted; backup is configured; cron and queues are operational; the old server can be turned off after final verification.

Currently, there is a store on OpenCart, and order emails are landing in spam. We need to ensure they go to Inbox (ukr.net gmail) and check it. The hosting provider wrote: Poor email delivery may be related to a low sender reputation - IP or domain. In this case, we can advise you to take the following steps to improve your sender reputation: 1. Switch the site to a dedicated IP address. When you use a shared hosting IP address with other users, your reputation may be harmed by the actions of other email senders. If one of the users sharing the same IP address sends spam or violates rules, it can affect the sender reputation for all users using that IP address, including you. Also, some email services limit the number of emails they accept from a single IP address, which can hinder the smooth operation of your email even if the overall reputation of the hosting's shared IP address is good. More details about ordering a dedicated IP address for hosting service: https://thehost.ua/hosting/ip 2. Check if SPF, DKIM, and DMARC records exist and are correctly configured on your domain. These authentication methods can significantly increase the likelihood of your email being delivered and are also mandatory for landing in "Inbox" on some email services. More details about the technical nuances of configuring these records can be found at: https://thehost.ua/wiki/email-reputation 3. Use the SMTP protocol for sending emails. 4. Use double opt-in for your mailing list. Do not launch email campaigns "blindly" - this increases the risk of landing in a spam trap for that email, which can lead to being blacklisted by spam filters for your IP or domain. 5. Avoid spam-like subject lines and stick to the context indicated in the subject line. Avoid trigger phrases, some of which are listed here: https://overloop.com/blog/455-email-spam-trigger-words-avoid-2018/

Development of Two Specialized Websites for Selling Spare PartsGeneral Information It is necessary to develop two specialized websites: Spare parts for ATVs, UTVs, SSVs, and other similar equipment. Spare parts for special equipment. Existing company website: https://kiaparts.com.ua/ The new projects should not be copies of the existing website. A modern solution should be proposed with an emphasis on SEO, speed of operation, convenience for clients and managers, as well as the possibility of further development and scaling.Main Goal of the Project To create not just an online store, but a platform for selling spare parts that will: be well indexed by Google; attract organic traffic; be easy for managers to fill; support large product catalogs; be easily scalable in the future. For me, it is more important to achieve the correct architecture and foundation of the project than to have a large number of features in the first version.Project Architecture Two separate websites are needed for clients. At the same time, it is desirable that they be built on a single platform: one administrative panel; shared functionality; one or related databases; separate domains; separate content; the possibility of different designs and layouts for each project. That is, essentially two separate websites for the client, but one management system for the company. The advantage will be a modular architecture that will allow launching new projects on the same platform in the future.SEO (one of the main priorities) The main task of the website is not only to sell products but also to gain maximum organic traffic from Google. For each spare part, a separate product page with its own URL must be created. An example of an existing product page is attached, demonstrating the general principle of filling in SEO information. For each product, it should be possible to add: part number; OEM number; cross numbers; analogs; brand; name; alternative names; characteristics; photos; description; PDF files; list of applications; list of equipment models. The main goal: For one spare part to be able to receive traffic from dozens of different search queries: OEM number; cross number; analog; name; brand; equipment model.Important Regarding Data Structure I do not want managers to manually write large texts for each page. It is desirable to implement a structured data system: Product → OEM number → Cross numbers → Analogs → Applications → Equipment models → SEO page That is, the manager fills in the information once, and the system uses it for: SEO; search; interlinking; filters; analogs.Catalog and Search It is necessary to implement search: by number; by part number; by OEM number; by cross number; by name; by brand. Desirable: auto-suggestions; fast search; search for analogs; fast operation even with a large catalog.Import and Update of Products Mandatory: Excel import; CSV import; data export; bulk price updates; bulk stock updates; bulk description updates; bulk photo updates; bulk SEO data updates.Inventory Management It is necessary to implement: multiple warehouses; availability display; product reservation; stock synchronization. In the future, the ability to synchronize with the old main website and other company projects will be necessary.Security It is necessary to provide for: administrative panel protection; two-factor authentication; access rights segregation; user action log; protection against common attacks; API and integration protection.Backup It is necessary to implement: automatic database dumps; automatic file backups; photo backups; document backups; automatic saving of copies to the cloud (Google Drive, AWS, Backblaze, or similar services); the ability for quick recovery after a failure or hacking.Further Development In the first stage, the implementation of the functionality listed below is not mandatory. However, the architecture should allow for its further implementation without the need to create a new website. In the future, the following may be implemented: AI search in the catalog; AI generation of product descriptions; AI generation of SEO content; automatic search for analogs; integration with CRM; integration with suppliers via API; automation of manager work; sales analytics; B2B client cabinets; marketing tools. Therefore, it is important that the architecture is ready for further development.Examples of Websites Like in structure, logic, and convenience: Chrysler.com.ua Secoparts.net Comtac.parts RockAuto.com There is no need to copy the design of these websites. They are provided as examples of a convenient catalog structure, search, and information presentation.Platform The use of OpenCart, WordPress/WooCommerce, or other platforms is allowed. Main requirements: good SEO architecture; fast operation; scalability; availability of API; possibility of further development. Please justify the choice of platform and explain the prospects for project development on it.Budget Estimated budget for the first stage: 3,000 – 7,000 USD for the entire project (two websites on a single platform). The budget can be reviewed after discussing the architecture and implementation stages. I am ready to consider phased implementation, but it is preferable to implement part of it more urgently for launch. It is more important to achieve the correct architecture and quality foundation for further development than to have the maximum number of features in the first version.What I Expect from the Contractor proposal for architecture; platform recommendation; examples of similar works; estimated budget; estimated timelines; vision for further project development. Experience in creating catalogs of auto parts, stores with searches by OEM numbers and cross numbers, as well as projects with large product catalogs will be a big plus. Also, please add a brief description of how you see the SEO architecture of the project and how organic growth of the catalog will be ensured. Photos are attached for a simple example of a page for organic search.
