Summary
🤩
Rockstar🎓
Top SchoolAnjan Roy is a Senior Chief Engineer with 7 years of hands-on experience in database administration, DevOps, and backend systems, currently based in Bengaluru. He has driven cloud-native database and infrastructure initiatives at companies like Demandbase and Samsung R&D, combining Agile practices with deep expertise in shell scripting, AWS, and enterprise databases. Beyond ops, Anjan contributes to blockchain and cryptography open-source projects—implementing light-client data availability checks, PoS bridge smart contracts for Matic/Polygon, and cryptographic primitives in the Miden VM—showing a rare blend of systems and crypto engineering. He is comfortable moving from low-level optimizations (secp256k1 and assembly for modular arithmetic) to high-level platform reliability, and has a B.Tech in Computer Science from West Bengal University of Technology. Colleagues know him for turning complex requirements into pragmatic, production-ready systems while still finding time to "keep learning" as his GitHub bio humbly notes.

Smart contracts that powers the PoS (proof-of-stake) based bridge mechanism for Matic Network
Role in this project:
Back-end Developer
Back-end DeveloperContributions:7 releases, 33 reviews, 305 commits in 1 year 6 months
Contributions summary:Anjan implemented smart contracts for a proof-of-stake (PoS) bridge mechanism within the Matic Network project. Their contributions included developing interfaces and predicate contracts for mintable ERC20 and ERC1155 tokens. Furthermore, they introduced proxy contracts to enable upgradability of these predicate contracts. Their work involved handling token locking, unlocking, and related operations within the bridge's core logic.

Back-end Developer & Cryptography EngineerContributions:141 reviews, 319 commits, 49 PRs in 10 months
Contributions summary:Anjan implemented and tested new cryptographic primitives within the Miden VM, focusing on SHA256 and Blake3 hashing algorithms. They developed assembly language routines for modular arithmetic and polynomial operations relevant to the Falcon signature algorithm. Additionally, the user refactored and optimized several core routines for point addition and multiplication within the secp256k1 elliptic curve, improving performance.
