Full stack developer | High-Concurrency System
I am a senior full stack engineer with 10 years of experience building high-performance, scalable applications across fintech, healthtech, and multi-tenant SaaS products. My most recent production system handled ~30,000 requests per minute at peak. On the backend I work with Node.js, Python and Go, and on the frontend I build with React, Vue.js and Angular. My broader stack includes TypeScript, NestJS, Express, Next.js, PostgreSQL, MongoDB, MySQL, Docker, microservices and AWS infrastructure end to end. Over the years I have delivered full stack solutions across payment systems, hospital management platforms, AI-driven compliance tools, accounting software and professional booking platforms. I am most effective on long-term engagements where I can own the architecture, database design, infrastructure and delivery end to end. Currently available full time and flexible on time-zone overlap.
