SUMMARY

PHP developer with 10+ years of experience.

Over the last 5 years, I have focused mainly on REST APIs, microservices, complex integrations, fintech and
SaaS platforms.

Main stack: PHP 7.x - 8.x, Laravel, Symfony. If needed, I can handle frontend tasks (Angular, Vue).

I can translate business requirements into practical technical solutions, write maintainable code, and quickly get
up to speed with large legacy systems.

I also have a background in media publishing and advertising: website and online store development, layout,
JS.

I use AI-assisted development tools to speed up development, debugging, and code review while maintaining
control over the final implementation.
Comfortable working in international teams
