What I'm looking for

I seek senior backend or tech-lead roles in remote-friendly teams focusing on scalable Node.js/TypeScript systems, performance, and reliable production operations.

I am a Senior Backend Developer with 10+ years building and operating production backends for e-commerce and fintech, focused on Node.js and TypeScript. I design REST APIs, integrations, and reliable background processing to support high-traffic services.

As a Tech Lead, I owned architecture, coding standards, and production releases for multiple products, and I have hands-on experience troubleshooting incidents on AWS and Debian systems. I improved system responsiveness using BullMQ for async jobs and Redis/Memcached for caching.

I've led and mentored engineering teams, coordinated releases, and worked closely with stakeholders to deliver on schedule while reducing production risk. My work includes SQL optimization across MariaDB/Galera, MySQL, PostgreSQL, and Oracle to lower database load.

I deliver practical, maintainable solutions and support mobile app integrations and post-release maintenance. I prioritize performance, reliability, and clear engineering practices to keep production systems stable and scalable.
