I think about software the way a user thinks about a door. They never wonder how it was built. They just know if it opened smoothly. 3+ years of shipping production systems, and that's still the only metric I trust. If the person using it has to think, something went wrong.

Software Engineer

● Active

Jul 2025 – Present · Dhaka, Bangladesh · On-site

Rebuilt a bank's legacy internet banking portals in Angular, with config-driven tables and reports, CASL permissions and GitLab CI/CD with Docker. Before that, owned the HR and employee self-service modules of a 12-module system for a government regulator.

Junior Software Engineer

Sep 2023 – Jun 2025 · Dhaka, Bangladesh · On-site

Worked on government systems: an office management system for a regulator, a customs advance-ruling e-filing system that passed UAT, and a microfinance system where I ported a service from Java to Node.js and made it run on both Oracle and PostgreSQL.

Reach for daily
Angular

Primary framework at work. RxJS, signals, lazy modules — been in this daily for 3+ years.

TypeScript

Write nothing without types these days. Plain JS feels wrong now.

Node.js

Backend runtime of choice. Async patterns, REST APIs, event-driven stuff.

PostgreSQL

First database I reach for. Schema design, indexing, complex queries.

Hp
Hapi.js

What we use at Celloscope. Solid plugin system, good for structured API work.

How I work
01Structure first. Messy foundations always come back to bite.
02I like understanding how all the pieces connect. Even when I'm deep in one layer, I want to know why it exists.
03Nothing is done on the first pass. I review, refine, and improve until it actually feels right.
04Useful beats impressive. I pick tools that work in production, not ones that look good in a readme.
Comfortable with
Next.js

Personal and client projects. App router, SSR, image handling.

React

Comfortable with hooks, context and component patterns.

Express

Lightweight APIs and middleware chains. Know it well.

JavaScript

Where it all started. Still write it, just with TypeScript on top.

OrOracle

Used extensively at Celloscope. SQL, stored procedures, views.

Firebase

Auth and Firestore for rapid prototypes and smaller projects.

Cypress

E2E testing. Writing tests that actually catch real bugs.

MongoDB

Document modeling and aggregation pipelines when relational is overkill.

Agent-driven development
Claude

Part of how I build now. I scope the task, let the agent work, and review what it produces.

Codex

Another agent in the workflow. The code still has to meet my standards before it ships.

Living Artifacts

Selected work across full-stack engineering, dashboards, and digital ecosystems.

Reflections

A few words from people I’ve built things with.

Sakib is someone who brings both reliability and clarity to a team. He communicates well, takes ownership of his work, and consistently delivers with attention to detail. Working with him made collaboration smooth and productive.
