What I'm looking for

I’m looking to build production, cloud-native systems end-to-end—high-performance APIs, scalable distributed backends, and blockchain features—where I can own architecture, optimize databases, and mentor teams that value quality and reliability.

I’m a Senior Software Engineer with 4+ years building production systems end-to-end across full-stack web apps, distributed backends, and blockchain infrastructure. I ship high-performance APIs in Node.js, TypeScript, and Python, build responsive frontends with React/Next.js, and scale systems with Redis, Docker, Kubernetes, and AWS.

At Magpie XYZ, I architected and shipped production backend systems and smart contracts for DeFi protocols collectively managing $1B+ in user assets. I designed high-performance GraphQL APIs and indexing pipelines using The Graph (achieving a 40% reduction in query latency), built cross-chain orchestration across 7 networks, and helped drive gas-optimized tokenomics that raised $4M+ in token sales.

I also engineered a self-healing on-chain transaction verification system that detects discrepancies and triggers real-time alerts, eliminating manual reconciliation overhead. Along the way, I own features end-to-end and mentor teams, staying strong in DSA, system design, and database optimization.
