What I'm looking for

I'm seeking an entry-level software engineering role building scalable full‑stack and blockchain systems, working with microservices and modern web stacks on collaborative teams that value performance, security, and rapid learning.

I build scalable full‑stack and blockchain applications, combining backend systems, microservices, and performant frontends. During a Software Development Engineer internship I developed RESTful APIs with React.js, Node.js and MongoDB, implemented JWT authentication, and improved load times and frontend performance.

I design and ship blockchain solutions on Solana using Rust (Anchor) and Next.js, focusing on secure on‑chain flows and low‑latency updates. I engineered an ICO DApp with atomic token transfers and wallet integrations for reliable purchases.

My projects include a MERN food ordering platform with Stripe payments and real‑time tracking, a Socket.IO‑powered chat app supporting group chats and file sharing, and a microservices e‑commerce platform with a GraphQL gateway, gRPC communication, PostgreSQL and Elasticsearch for efficient search.

I solve competitive programming problems regularly and have led a campus club team, delivering events and content. I look for collaborative roles where I can work on high‑performance, secure systems and continue growing across backend, frontend, and blockchain domains.
