I've built and scaled production web platforms at Apt Tech Studio and Devsinc using Node.js, React.js, AWS, PostgreSQL, Redis, and Docker. I own backend architecture, application performance, deployment strategy, and production reliability.
For Tomarket, I led backend architecture for a high-concurrency ordering platform that remained stable beyond 10k concurrent users, using Redis caching, asynchronous processing, WebSockets, and AWS deployment workflows. I also improved legacy backend maintainability and response times by approximately 50% at Devsinc.
I've led teams of 5+ engineers through technical decisions, code reviews, debugging, and architecture discussions. I enjoy solving production bottlenecks through query optimization, indexing, caching, monitoring, and reliable CI/CD practices.
