Support and refinement of the database on Yii

Budget: 1000 UAH Deadline: 1 day

Good day.

I will accept your project for support. The Yii framework (Yii1 or Yii2) is excellent for scalable systems, and having a connection with the previous developer is a huge plus that will allow me to quickly understand the nuances of the current architecture and database structure.

The specified budget of 1000 UAH is conditional and suitable for making the first small adjustments. For ongoing support, we can agree on a fixed cost for each task pool or an hourly rate.

Technical solution
Database and code audit:

I will deploy a copy of the project in a local environment, analyze the database structure (indexes, foreign key table relationships, presence of outdated or duplicate fields).

I will check the ActiveRecord models of the framework to understand how the application logic interacts with the database and exclude "heavy" SQL queries that may slow down the website.

Safe implementation of changes and migrations:

All changes to the database structure (adding new tables, changing field types) will be implemented strictly through the Yii migration mechanism (yii migrate). This guarantees that when transferring changes from the test server to the production server, nothing will break, and client data will not be lost.

The logic of new enhancements will be separated into individual components or service layers to maintain code cleanliness and the architectural pattern MVC established in Yii.

Query optimization (SQL):

I will analyze logs and slow queries. If the database is overloaded, I will set up proper lazy/eager loading of data (with() in ActiveRecord), add necessary indexes in MySQL/PostgreSQL, and optimize complex selections.

What is needed to start and assess:
What version of the framework is being used (Yii 1.1 or the second branch Yii2)?

The first list of adjustments or a description of the task that needs to be completed first.

Access to the repository (GitHub/GitLab) or an archive with the code and database dump for review.

Send the details in private messages — I will promptly study the task, communicate with your previous executor if necessary, and formulate a clear work plan. Expand

Serg, if part of the logic is already created and there is a connection with the previous executor, I will quickly understand the code and take over the support of the Yii project. Experience with Laravel and Vue helps me see the system as a whole: I fix bugs, refine the database, and carefully make changes without unnecessary risks. I can start with an audit of the structure and alignment of priorities.

Hello! I work with Yii2 and MySQL, and I have often taken over projects from other developers. Your description is general, so my main question right away is: are the changes more related to the database itself (structure, queries, migrations) or to the functionality on top? I am ready to start with a small task so you can see me in action.

Budget: 1000 UAH Deadline: 3 days

Serg, hello. In such transfers, the main headache is usually not in the code itself, but in the fact that the actual database schema has diverged from the migrations - someone edited the tables manually bypassing yii migrate, and migrate/history no longer matches the structure. Then any "refinement" turns into excavation.

A couple of questions to avoid guessing: what exactly are we fixing - migrations and specific tables or logic in the models? And does the previous executor still have access to the repository and the database dump?

I would start with an audit of the current schema and migrations, then make targeted fixes. I can start immediately.

I have been working with PHP/MySQL and Yii-like frameworks for several years, and I also run my own project in PHP. Let me know what exactly needs to be completed - we will discuss the details.

Hello!

Support for the Yii project with database adjustments and live communication with the previous contractor is primarily about quickly immersing in the existing logic without the risk of breaking something.

I suggest starting with a brief audit of the current database and tasks: looking at the structure, understanding the connections with the previous contractor, and only after that fixing the scope of adjustments and deadlines.

Could you please clarify the version of Yii (1 or 2) and what specific database refinements are planned — this is critical for assessing the complexity.

I will be able to estimate the timelines and costs after reviewing the code, approximately 2-3 days for the initial immersion and audit.

I am ready to discuss the details and access if this format of starting works for you. Expand

Hello!

I am a Full-Stack Software Engineer with over 7 years of experience in developing websites, SaaS solutions, complex web platforms, and MVPs for startups - from idea and architecture to production and support.

I work not only as a developer but also with a focus on business logic, scalability, and long-term support of solutions. My portfolio includes examples of completed projects of varying complexity.

Technology stack:
PHP (Laravel, Symfony, Yii2),
Frontend: JavaScript (Vue.js, React.js), HTML5, CSS3,
Databases: MySQL, PostgreSQL.

Regarding timelines and costs - at this stage, it is difficult to accurately assess them without clarifying the requirements. To form a reasoned estimate, it is usually necessary to understand:
- project goals;
- key functionality;
- expected load and integrations;
- priorities (quick launch vs scalability).

I suggest starting with a brief clarification of requirements or a call/email - after that, I will be able to provide a realistic estimate on timelines, budget, and implementation options.

I would be happy to discuss the details. Expand

Good day!

I am currently working on a similar project: door24.com.ua — a custom Yii2 platform in Docker, I have entered someone else's code without documentation and am still working on it.

From the description, it is not clear what exactly needs to be done, so I have three questions:

1. "Corrections and improvements to the base" — is this the database or the basic functionality of the platform?
2. What is currently in progress — is there a list of tasks or is constant support needed for requests?
3. Yii2 or Yii1, and what version of PHP?

Based on these answers, I will provide an exact price and timeline. The amount in the bid is approximate. Expand

Good day!
Overall, the task is clear. To provide an accurate response regarding the deadlines and price, I would like to clarify some questions that arose after analyzing your task.
Please write in private messages – we will discuss the details and your wishes.

Budget: 4000 UAH Deadline: 7 days

Good day! I understood the terms of reference: support for the existing project on Yii — edits, improvements, working with the database; there is partial communication with the previous contractor. I will summarize the main points:
- I will analyze the current code and database schema, documenting how it works now;
- I will make edits and improvements selectively, without "rewriting everything";
- Changes in the database — carefully (migrations/backup, without data loss);
- I will quickly remove access, nuances, and known issues with the previous contractor.
Experience: PHP and MySQL in production (websites/services), support and improvement of existing systems, integrations, working with someone else's code after handover. I will pick up Yii from your repository and the terms of reference for edits.
To assess the first stage, please clarify:
1) Yii 1 or Yii 2 (or version), link to the repo/hosting;
2) what are the current pain points — a list of 3–5 priority edits;
3) what database (MySQL/PostgreSQL) and is there a test environment;
4) format: hours/month of support or fixed price for a task package.
After your responses — the timeline and cost for the initial block. I am ready to connect after access is provided. Expand

I need a person who will take over a Yii project and make changes without stopping development. The first step: I will familiarize myself with the current database structure and code, and talk to the previous executor to not lose context. Next: I will document every schema change through Yii migrations to ensure safe rollback. For refinements, I will use ActiveRecord or pure SQL depending on the complexity of the query.

What are the most prioritized tasks right now: bugs in the database, new features, or query optimization?
