What I'm looking for

I’m looking to leverage my backend-first full-stack skills to build secure, scalable APIs and real product experiences—working closely with teams to deliver reliable software, strong performance, and clean architecture in fast-moving projects.

I’m a full-stack developer, majoring on the backend, with 5+ years of experience delivering robust software solutions across e-commerce, real estate, and fintech. I translate business requirements into scalable applications using modern frameworks and an API-first mindset.

In recent roles, I engineered secure investor-facing APIs, standardized route architecture using member_uid, and built granular reporting modules with filtering and pagination. I also optimized data aggregation pipelines for KYC documentation, portfolio valuations, and trade history—prioritizing reliability through rigorous end-to-end verification.

I’ve built end-to-end marketplace and auction backends with secure authentication (JWT/OAuth/OTP), real-time features (Socket.IO), and production monitoring (Sentry). I implement strong security practices like rate limiting, Helmet, and secure file handling with AWS S3, and I deploy SSR applications for dependable performance.

I’m equally comfortable owning frontend architecture—engineering e-commerce experiences in Next.js with responsive UI, accessible design standards, and predictable state management with Zustand. I enjoy collaborating cross-functionally to enhance performance, scalability, and the overall user journey.
