Remote | Jan 2026 – Present

Built high-throughput backend services in Go for ingestion, batching, compression, and durable storage of large-scale event/log data
Architected a hybrid on-chain/off-chain architecture storing verifiable references on blockchain while persisting bulk data in decentralized object storage to reduce costs and improve scalability.
Implemented peer-to-peer networking features including NAT traversal and direct node-to-node communication without centralized servers using libp2p
Developed indexed query engine with selective retrieval and progressive streaming, enabling efficient search across large immutable datasets
Technologies: Go, Python, Solidity, PostgreSQL, libp2p, Foundry, Decentralized Storage

Remote | Sept 2025 – Present

Built a quantum-resistant identity system using ML-DSA (CRYSTALS-Dilithium) with a Rust–Node.js hybrid backend cryptographic core, enabling sub-50ms deterministic W3ID generation.
Designed a bias-free 12-digit ID derivation pipeline using SHAKE256 entropy, keyed BLAKE3 hashing, and 48-bit rejection sampling, ensuring uniform distribution and zero collisions at scale.
Implemented a 2-of-3 MPC non-custodial smart wallet infrastructure via Openfort SDK with encrypted recovery sessions and no single point of failure.
Built a multi-tenant developer SDK platform with OAuth-style auth, AES-256-GCM encrypted API keys, secure webhooks, and hardened rate-limited REST APIs.
Technologies: NodeJs, Typescript, Rust, PostgreSQL, Cryptography

Remote | July 2025 – Aug 2025

Designed account abstraction workflows using PrivySDK to improve on-chain UX
Migrated NFT minting from Solana cNFTs to EVM-compatible NFTs while preserving backend workflow
Maintained backend deployment workflows on Monad EVM

Auth-driven wallet provisioning with Clerk webhooks, automatically generating W3IDs and MPC smart wallets on user signup
2-of-3 MPC non-custodial wallet infra via Openfort SDK with encrypted recovery and no single point of failure
Multi-tenant SDK enabling third-party apps to create and manage wallets securely using OAuth-style auth and API keys
Hardened wallet APIs with encrypted credentials, rate limiting, and secure wallet lifecycle tracking across chains

Designed a decentralized observability pipeline to ingest, index, and query logs while storing raw data immutably in content-addressed object storage
Built high-throughput Go ingestion service performing normalization, batching, and compression to reduce storage and transfer overhead
Implemented indexed retrieval engine that selectively fetches relevant log batches and streams filtered results progressively to clients
Developed multi-tenant alerting and query system with project-scoped API keys and efficient metadata indexing in PostgreSQL
Technologies: Go, PostgreSQL, Akave O3(S3-Compatible), NextJs, Echo, Pgx, tern

Developed ERC-8004 identity and reputation smart contracts enabling on-chain agent discovery and trust scoring
Implemented com
