Hello, I'm Celina Apu
A Full-Stack Developer with 4 years of experience building fintech and marketplace platforms. I write clean code, ship fast, and take full ownership — from the first line of code to production.
Professional Full Stack Developer & Problem Solver
I architect and deploy scalable web applications using the MERN stack, with proven experience at Arya Realties (fintech platform) and Kraftaa (marketplace platform). I reduced API error rates by ~15% through TypeScript adoption at Kraftaa, and implemented Google Auth, SEO, Sentry monitoring, and analytics at Arya Realties. I'm passionate about clean code, performance, and delivering results that move the business forward.
