Senior Backend Engineer @ Prospeo | Ex-Lead Engineer @ 0Chain | IIT BHU
I build backend infrastructure that survives production. Currently owning billing, accounts, and admin systems at Prospeo. Previously led core development on a Layer 1 blockchain at 0Chain — 210M+ transactions, 145M+ blocks, 103 miners, 200+ blobbers, zero major production failures.
Now exploring zero-knowledge proofs and privacy-preserving identity verification for India.
Prospeo — Own the complete billing system, accounts/team infrastructure, and admin panel end-to-end. Python, MongoDB, Redis, AWS.
0Chain — Led a team of 15 engineers building a Layer 1 blockchain and decentralized storage platform from scratch. Personally architected the tokenomics system (block rewards, staking pools, fee distribution, penalty enforcement) and overhauled storage smart contracts through 225+ merged PRs. Shipped consensus upgrades, built the 0Box API powering 11 production applications, and ran the release process across all distributed components.
ZK-Verify (personal project, in progress) — Privacy-preserving identity verification API using zero-knowledge proofs on UIDAI-signed Aadhaar data. Circom circuits, snarkjs, Groth16 proving system.
Languages: Python, Golang, Rust, TypeScript
Infrastructure: MongoDB, PostgreSQL, Redis, ElasticSearch, AWS, Docker, Kafka
Cryptography: ZK proofs (Circom, snarkjs, Groth16), blockchain consensus, smart contracts
