Full Stack Engineer at Shroud Wallet building BIP-352 Silent Payments workflows and Bitcoin privacy infrastructure.

India
Message

At Shroud Wallet, I’m a core contributor to a non-custodial Bitcoin privacy wallet supporting BIP-352 Silent Payments. I implemented send and receive workflows, UTXO tracking, and payment state management to improve reliability across transaction lifecycle states.

I also built onboarding and recovery infrastructure, and designed modular CI/CD pipelines from scratch for reproducible builds, automated testing, and consistent releases. For the Silent Payments indexer, I introduced transactional block processing, API response caching, and database query optimizations that reduced scan overhead by 15%.

I built and maintain Bitcoin for Bharat, an India-focused Bitcoin education and resource platform, and contribute to Bitcoin Development Kit wallet infrastructure. Earlier, as a Research Intern at Blockchain Commons, I expanded the Learning Bitcoin from the Command Line v2.0 curriculum and researched human-rights Bitcoin use cases.
