Engineering lead for AI and web technology based products. Coding since 2013, professionally since 2016.
My work sits between models and production: system architecture for AI and software that has to scale, and product design for the people on the other end of it. Across language and vision, I am drawn to the parts that are easy to get wrong, how performance holds up under real traffic, how a system is measured once it leaves the lab, and how it is designed so that it can grow. Products I have helped build have reached 400,000+ users across three continents.
AI and machine learning
- Language — LLM and RAG architectures, agents and tool use, conversational AI and dialogue design. Intent classification and the migration path from classifier-based NLU to LLM-driven understanding. Multilingual and code-switched systems, including Bangla and Roman Bangla, where there is no standard orthography to lean on. LangChain, RASA.
- Vision — OpenCV, YOLO, skeletal mapping and pose estimation with MMPose and OpenPose, and real-time inference on embedded hardware.
- Around the model — retrieval and evaluation pipelines, measuring performance on live traffic, and serving models under production load.
Web — Node.js in depth: Express, NestJS, microservices, event-driven architecture, WebSockets and Server-Sent Events. Next.js, React and React Native on the front end. MongoDB, PostgreSQL and Redis for data; AWS, GCP, Docker and Linux underneath.
Blockchain — Ethereum and EVM chains, IPFS and Filecoin, NFT distribution systems, dApp architecture and frontend security models.
Co-founder and engineering lead of an engineering studio. Our own products:
- engaze.ai — restaurant management platform used by 2,000+ restaurants, with AI conversational ordering on top of it.
- Diva — sanitary pad vending machines for public spaces across Bangladesh, with cash, RFID and bKash payment paths.
Most of what I build there is closed-source.
Six years as a software engineer, part-time and remote. I worked on the frontend architecture and security model for ChainSafe Files, a decentralised storage product on IPFS, Ethereum and Filecoin, and contributed to Lootboxes, an NFT distribution system for game developers on EVM chains. That work is open source and linked below.
| country-currency-utils | Countries, currencies and monetary formatting · npm |
| sse-manager | Server-Sent Events with namespaces, rooms and a Redis adapter for horizontal scaling · npm |
| tutsmaker | Browser agent that explores a web app and writes illustrated tutorials — Playwright, dual LLM backends |
| agent-conv | Voice assistant on OpenAI's Realtime API, with natural interruption handling |
| ChainSafe/ui-monorepo | ChainSafe Files — decentralised storage on IPFS, Ethereum and Filecoin. Contributed to the frontend architecture and security model |
| ChainSafe/nodewatch-ui | Frontend for NodeWatch, a devp2p crawler mapping Ethereum consensus-layer nodes |
- Managing real-time communication from a Node.js server with Server-Sent Events
- Deploying Node.js on AWS, in three parts — Dockerize and deploy to EC2 · auto-scale and load balance · CI/CD with CodeBuild, CodeDeploy and CodePipeline
- Managing countries and currencies with JS
- World Summit Awards 2025 — Winner, Business & Commerce, for engaze.ai. Selected by the WSA Grand Jury from among 180+ participating UN member states.
- NASA Space Apps Challenge 2016 — Regional Champion and Global Nominee for Winger, an inertial-sensing device that backtracks your path when external communication is unavailable.
