Creation of an exchange website and subsequent integration

Budget: 25000 UAH Deadline: 7 days

Hello!

I am ready to develop a full-fledged exchange website according to the requirements of the BestChange listing. I will implement an exchange form with automatic recalculation, displaying the rate and commission, creating requests with statuses, as well as a status tracker for clients.

I will develop a user-friendly admin panel for managing rates, reserves, limits, and requests, add a simple referral system, and log operations. I will set up the export of rates and reserves in the format accepted by BestChange, as well as notifications about requests (email, and if necessary, Telegram/SMS).

I will create a responsive, fast website with SSL, a well-thought-out database structure, and basic protection (anti-spam, protection against duplicates, SQL injections, XSS, brute force). I will provide for automatic, semi-automatic, and manual operation modes of the exchange.

I look forward to collaborating! :)

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 implemented 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 justified estimate, it is usually necessary to understand:
- project goals;
- key functionality;
- expected load and integrations;
- priorities (quick launch vs scaling).

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
