Hello, I'm Mrimmoy H Shimanto. I'm a full-stack engineer at Hgraph, building web3 & blockchain infrastructure on the Hedera ecosystem.

About me

I'm a blockchain engineer at Hgraph, where I work across the full stack of web3 infrastructure - from data indexing and analytics pipelines on the Hedera network and beyond, to the dApps and developer tooling that sit on top of them. My day-to-day spans designing GraphQL APIs over indexed chain data, building production-grade backends, and shipping responsive frontends that make on-chain data legible to end users.

Before Hgraph I worked across several remote teams on NFT marketplaces, payment platforms, and full-stack web applications, which gave me a product-minded engineering perspective: I care about reliability, clean APIs, and developer experience as much as features. I'm comfortable across TypeScript, Next.js, NestJS, Node.js, GraphQL, PostgreSQL, the Hedera SDKs, and EVM tooling (Solidity, Wagmi/Viem, ethers), as well as cross-chain protocols such as LayerZero. I'm equally happy debugging an indexer, scoping a new service, or pairing on a frontend.

Outside of work I read philosophy and Islamic texts, teach Arabic, and spend time with my daughter.
