Profile
About
A concise summary for recruiters and hiring managers—focused on systems, scale, and outcomes.
Software engineer with production backend depth and a solo Web3 builder track record. By day: Java/Spring Boot/Kafka/Kubernetes services running for 50K+ learners at Vedantu — 40% API latency improvement, 60% faster document delivery, 80% reduction in manual ops. After hours: solo Solana builds with Rust, Anchor, and the Umbra SDK, plus hackathon submissions across Solana privacy, Civic Auth identity, and AI co-pilots for crypto investors. I cross from latency-dashboard production engineering into shipping verifiable on-chain products end-to-end.
