🚀 Senior Fullstack Developer (Frontend Heavy) · React · Next.js · TypeScript · Node.js
6 years of experience building and scaling web applications across B2B and B2C domains — from a multi-tenant vendor platform serving 100+ external vendors, to high-traffic e-commerce modules used by millions. I care about frontend architecture that stays maintainable, performance you can measure, and shipping features end to end.
