What I'm looking for

I seek backend roles focused on scalable, secure API systems, pragmatic engineering, strong observability, and collaborative agile teams where I can drive performance and reliability improvements.

I am a Senior Backend Engineer with 7+ years of hands-on experience in PHP and Laravel, focused on architecting, scaling, and securing high-performance web applications. I specialize in performance optimization, backend architecture, asynchronous processing, and building robust financial and marketplace systems.

My achievements include a 10x API performance improvement, refactoring large legacy codebases toward SOLID design, eliminating race conditions, and hardening applications against OWASP Top 10 vulnerabilities. I have designed billing and payment routing systems, integrated multiple third-party banking APIs, and authored OpenAPI documentation for large endpoint surfaces.

I work well in agile, cross-functional teams and blend pragmatic engineering with strong attention to reliability, observability, and maintainability. I prioritize clear API contracts, automated testing strategies, and production monitoring to ensure resilient systems and faster onboarding.
