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
- PR1, PR2
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
- Contributions:
- Technologies: NodeJs, Typescript, PostgreSQL
- 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
