What I'm looking for

I’m looking to build and scale cloud-native products where performance, reliability, and clean system design matter—owning architecture, CI/CD delivery, and pragmatic testing to ship high-impact improvements quickly.

I’m a Senior Software Engineer with 8+ years of hands-on experience designing, developing, and maintaining scalable web applications, cloud-native platforms, and enterprise solutions. I focus on turning architecture into production systems that perform reliably under real load.

In my recent work, I’ve reduced API response times by 50%+ and improved overall system performance by 20–25% through algorithmic optimization and targeted performance work. I’ve also optimized databases—cutting slow query load by 40%+ using indexing and query optimization—and I use EXPLAIN ANALYZE to quickly find and fix bottlenecks.

I build end-to-end delivery pipelines and high-availability services. By implementing CI/CD pipelines, I increased deployment frequency from weekly to multiple times per day, and I’ve delivered systems serving 10,000+ daily users with 99.9% uptime.

My toolkit spans AWS and Google Cloud Platform, microservices principles, and modern backend/frontend development. I’m experienced with PHP, Go, Node.js, React, and Vue.js, and I emphasize maintainability, clean design patterns (SOLID/DDD), and testing—from unit and integration to end-to-end—to keep teams shipping with confidence.
