About me.

Marzuk Rahman Adi working on a laptop
Marzuk Rahman Adi Dhaka, Bangladesh

I’m a full-stack product engineer in Dhaka. I take products from the first screen through launch and keep the systems behind them running.

What I do

  • Web & mobile apps

    I build the websites and phone apps people use to book appointments, browse products, or get work done.

    • React
    • Next.js
    • React Native
    • TypeScript
    • Vue.js

  • Backend services

    I build the services that handle things like saving a booking, sending a notification, and connecting different tools.

    • Node.js
    • NestJS
    • PHP
    • Symfony
    • Laravel
    • Python

  • Distributed systems & data

    I split large jobs across multiple workers so they can run in parallel and retry individual failures. At Scrupp, that meant processing lead data in the background while users searched millions of records.

    • PostgreSQL
    • MongoDB
    • Redis
    • RabbitMQ
    • Socket.IO
    • Prometheus

  • Cloud & infrastructure

    I get apps online, set up repeatable releases, and monitor the systems that keep them running.

    • AWS
    • Docker
    • Terraform
    • Linux
    • Azure
    • Cloudflare
