# A little about the engineer

I am a Computer Science student and software engineer working across Node.js, AdonisJS, Python, Django, real-time applications, APIs, automation, and AI integrations. Technology is a tool; the real work is understanding the problem and designing the right system around it.

My work spans real-time services, campaign automation, education analytics, IoT data pipelines, and AI-assisted workflows. Across each project, I care about practical architecture, understandable code, and dependable software that solves a measurable problem.

EDUCATIONBSc in Computer Science & Engineering · Dhaka International University
01

Problem-first thinking

I start with the real problem, then shape the data flow, boundaries, and technology around it.

02

Practical architecture

I choose clear, dependable solutions that fit the real scale and constraints of a product.

03

Continuous learning

I strengthen fundamentals through project work, experimentation, and problem solving.

Technical toolkit
