About

Professional summary

I am a Full Stack Developer with more than three years of experience building and maintaining web platforms, with a focus on PHP, Laravel, MySQL, and JavaScript.

I have worked on production CRM platforms serving more than 90 clients and managing databases containing hundreds of thousands of customer records. I am comfortable maintaining existing systems, resolving production issues, and improving business workflows.

I have experience integrating international payment gateways, including multi-gateway payment flows involving tokens, orders, confirmations, and fraud-validation logic. I also develop REST APIs and backend services with data validation and authentication.

My full-stack background includes e-commerce functionality, dynamic guest checkout flows, real-time capacity control, multilingual systems, and desktop user interfaces built with Electron. I adapt quickly to different technology stacks and project requirements.

I am self-taught, detail-oriented, and proactive in understanding unfamiliar codebases. I value clean programming practices, design patterns, practical UX considerations, and efficient debugging processes.
