EN I am Rinat Sarmuldin, a fullstack developer from Uralsk, Kazakhstan, with 4+ years of commercial web development experience. My strongest area is PHP backend development: application logic, databases, admin panels, REST APIs, integrations, debugging and deployment support.
I work with practical business systems where the important part is not only to make a page look correct, but also to keep the whole flow reliable: forms, validation, authorization, database records, admin workflows, API contracts, logs and regression checks after changes.
RU Я Ринат Сармулдин, fullstack-разработчик из Уральска, Казахстан. У меня 4+ года коммерческого опыта в веб-разработке. Моя сильная сторона - PHP backend: логика приложения, базы данных, админ-панели, REST API, интеграции, отладка и сопровождение.
Я умею работать с существующими проектами: разобраться в структуре, найти реальную причину ошибки, внести аккуратные изменения и проверить основные сценарии, не переписывая лишнее.
- Build and maintain PHP web applications with Laravel, Symfony, Yii2 and Bitrix.
- Design backend logic, REST APIs, admin panels, CRUD flows and integrations.
- Work with MySQL/PostgreSQL: schema, queries, migrations, debugging and data checks.
- Support full web flows: frontend forms, JavaScript behavior, backend validation, database writes and admin output.
- Prepare reproducible local environments with Docker, Docker Compose, Linux and Nginx.
- Debug production-like issues through logs, SQL, recent code changes and server configuration.
- Review changes carefully and test the main user scenarios before considering a task finished.

I prefer careful, understandable engineering. Before changing code, I try to understand the existing structure, the database model, the request flow and the reason behind the bug or feature request.
For me, a good change is not only "it works on my screen". It should be readable, safe for existing behavior, easy to review and possible to verify with clear steps. I pay attention to validation, access rules, SQL safety, edge cases, null values and the small details that often become production bugs later.
