About

Botanist turned
engineer.

I'm Muhaiminul — a software engineer building mobile, desktop, and web applications for businesses and people around the world. I work with React Native, React, and Node.js, including systems that need to work reliably offline. I'm also expanding into native Android development with Kotlin and Jetpack Compose, and using Claude Code and Codex in my daily development workflow.

Journey

How I got here

Four years from first line of Python to leading mobile work on production systems.

2022

A career change, on purpose

I finished a Master’s in Botany from National University of Bangladesh and started down the conventional path — then realised it wasn’t the one I wanted. In August 2022 I began teaching myself to program.

2022

Foundations with CS50P

Harvard’s CS50P on edX gave me the fundamentals: how a program is structured, how to debug, and how to keep going when nothing works.

2023

React, then the whole stack

Meta’s Front-End Developer Certificate introduced me to React. Programming Hero’s Complete Web Development course and its Level 2 programme took me through the MERN stack, TypeScript, PostgreSQL, Prisma, Docker, AWS and GraphQL.

2023

First engineering role

Joined Neutron Ltd. as a Software Engineer. Promoted to Team Lead within five months, mentoring five MERN developers while shipping two production SaaS platforms.

2024

Going native

Completed Meta’s React Native Specialization and led Orii’s mobile work — dual POS apps for florists and restaurants, both published on the Apple App Store.

2026

Expanding into Android and AI

Completed Meta’s Android UI Development Specialization, building on Kotlin and Jetpack Compose, along with Google’s AI Professional Certificate and IBM’s IT and Cloud Fundamentals Specialization.

2026

Warehouse-scale systems

Now at Techzu as Software Engineer III, architecting an ERP and its offline-first Portable Data Terminal app for real-time warehouse operations.

Outside the editor

I write about what I learn shipping production apps — offline-first architecture, Expo SQLite, payment integrations — over on Medium. I keep an open-source component library, Aargon UI, for the React Native animation patterns I reach for repeatedly.

Available for new work

Have an app that needs building?

Whether it's a new iOS and Android product, a desktop tool, or the backend that holds it all together — tell me what you're building.
