Farhan Yaseen
Senior Full Stack Engineer building scalable SaaS, fintech, and AI-native systems.
I build and run production systems on Node.js, NestJS, TypeScript, React, Next.js, AWS, and GCP. Most of my work comes down to keeping things reliable, fast, and cheap to run. Lately I ship production AI features with the Claude API and tool use, and I build with Claude Code and Cursor every day. 10+ years across SaaS, fintech, search, gaming, and cloud platforms.
