Full-stack & Web3 Developer · Khulna, Bangladesh

I build
APIs
for web & chain.

I'm Md. Sazid Hossain. I make Laravel business apps and, lately, Node.js services that let them talk to EVM chains and TRON: wallets, balances, token transfers and transaction history behind a clean REST API.

Now: Laravel + Web3 backends at Grow Tech

01 · About

From admin panels to on-chain backends.

I'm a full-stack developer who started out building Laravel apps for businesses: an events company site, an inventory and distribution system, and a journal platform with its own editorial admin. That meant a lot of the unglamorous work I enjoy: data models, admin panels, roles and forms.

These days I'm moving into Web3 backend work. I write Node.js and Express services that let a Laravel app generate wallets, read balances and send native coins and ERC-20 / TRC-20 tokens on EVM chains and TRON. On the side I fork and study other people's infrastructure (bridges, indexer nodes, chain registries) to learn how it's built.

I'm currently with Grow Tech, based in Khulna, Bangladesh.
