Architected and deployed a production-grade Web3 infrastructure platform, scaling it from a single-chain custody solution to a multi-chain settlement layer. Engineered agentic trading engines and smart-contract systems while owning the full stack solo — resilient cloud environments, GitLab CI/CD, and custom backend services for secure DeFi interactions.

About
Nidhin is a distributed ledger technology specialist with five years of experience building blockchain protocols and infrastructure, including consensus systems, self-custodial wallets, staking, and settlement layers.
He currently builds Fexr, an independent Web3 infrastructure platform that evolved from a single chain custody solution into a multichain settlement layer with agentic trading engines and smart contract integrations. He owns the full stack, managing protocol integrations, backend services for secure DeFi interactions, and the cloud-native deployment pipeline.
Previously, as Lead Engineer at Jupiter Meta, he was a founding engineering team member for the JMDT blockchain, a zero-knowledge rollup on zkEVM built to streamline internal asset settlement. He designed the ZK circuit architectures and proof-verification pipelines core to the product roadmap.
Before that, as Co-Lead on the Rubix Layer 1 protocol, he helped develop the zero-gas-fee Proof-of-Pledge network from testnet through mainnet. He delivered the first native wallet for the network, introducing Decentralized Identifier support via an early implementation of image-based nonlinear secret sharing. He built core protocol services including peer-to-peer networking, transaction processing, consensus, and asset custody. In 2023, he led the full migration of the protocol stack from Spring Boot to Golang, cutting memory footprint and improving runtime performance while driving open-source development and developer onboarding.
His research spans cyber security and decentralized systems. He developed a permissioned blockchain architecture for data provenance for a national defense organization at TIFAC-CORE in Cyber Security, and a Hyperledger testbed for peer-to-peer energy trading on IoT hardware at the Amrita Center for Wireless Networks and Applications. He authored four peer-reviewed papers on blockchain security, V2X message verification, energy markets, and decentralized mobility, published across IEEE COMSNETS, Springer ICTIS, and ACM workshops at SenSys.
At Amrita University, Nidhin led the Google Developer Student Club and contributed to the FOSS club, ranked in the top 10 nationally for Google Summer of Code selections. He now works at the intersection of engineering and go-to-market strategy, helping teams evaluate, integrate, and adopt digital asset infrastructure.

Experience
Founding engineering team member; contributed to the design and launch of the JMDT blockchain, an in-house zero-knowledge rollup on zkEVM built to streamline internal asset settlement. Designed ZK circuit architectures and proof-verification pipelines at the core of the product roadmap.
Coordinated the engineering team behind the network's foundational infrastructure across testnet and mainnet. Delivered the network's first native wallet with Decentralized Identifier (DID) support via image-based non-linear secret sharing. Built core protocol services — P2P networking, transaction processing, Proof-of-Pledge consensus, and asset custody — in Spring Boot, then led the full migration to Golang (2023), cutting memory footprint and improving runtime performance.
Developed a secure, permissioned blockchain architecture establishing immutable data provenance and strict audit trails for a national defense organization.
Built a Hyperledger blockchain test-bed of 7 Raspberry Pi nodes running Golang smart contracts; deployed and validated P2P energy-trading workflows on constrained IoT hardware.
Authored machine-learning tutorials and technical guides on TensorFlow for a global audience of developers and data scientists.
Indie Projects
Blockchain network on ARMv7/AArch64 Raspberry Pi devices at Amrita AWNA for sharing and managing campus resources via containerised nodes.
Built during COVID-19 lockdown in partnership with local vendors — logistics combined with a convenient grocery delivery experience.
Prototyped a VoIP-based proof-of-concept for a startup's investment pitch and internal testing.
Collaboration app for a short film festival — integrated API, Chat, Google Sign-in, and token auth for iOS and Android.
Virtual wallet for stalls at Robotsavam-2017 fest. Data Tables API, JSON, jQuery, AJAX.
