What I'm looking for

I’m looking for a backend-focused full-stack role where I can modernize legacy systems, build scalable microservices and event-driven architectures, and keep improving performance, reliability, and user experience with measurable impact.

I’m a Full Stack Software Engineer with 5+ years of experience building and scaling production systems across advertising, ERP, and government sectors. I’m backend-focused with strong expertise in Node.js, distributed systems, and performance optimization, while delivering modern frontend experiences with React.js.

In my recent work, I’ve improved legacy systems to reach 80%+ user satisfaction, delivered workflows with 70%+ approval, and increased efficiency and revenue by 22%+. I’ve also reduced database query time by 15%+ and improved performance and reduced latency by up to 40%, helping raise reliability and user satisfaction to 80%+. I enjoy modernizing legacy platforms into scalable architectures—especially through microservices, REST APIs, and event-driven systems.
