Featured software case study
AHLC
A multi-tenant academic platform built around separated roles, dependable transactions, and infrastructure designed for real student and teacher traffic.
Abrar Abdullah Rafid · Software developer & hardware hobbyist
Software by profession. Hardware by curiosity.
I’m Abrar, a software developer and undergraduate student based in Dhaka. I currently work across web development and AI-focused roles while building independent software and hardware projects. I’m looking for new opportunities to learn, contribute, and grow with ambitious teams.
Selected work
Evidence before credentials.
Projects come first because they show how I frame problems, make decisions, and carry systems into real use.

Explore the hardware studyCapabilities
One practical mindset, three working layers.
I organize skills by what they help me build. Technologies are evidence-backed where possible and separated from tools I am still exploring.
Software, infrastructure, and electronics are not isolated interests. They are layers of the same system.

Academic foundation
Strong fundamentals, directed by curiosity.
My formal science education is the foundation; building complete systems is how I test and extend what I learn.

Continued learning
Credentials as supporting evidence.
Courses and simulations extend my range, but they support—not replace—the project work and academic record above.

How I think
Building with the whole system in mind.
I care about how a system behaves in the real world—not only how it runs locally.
Languages · Bengali native · English professional
Architecture before complexity
Understand the problem, boundaries, and trade-offs before adding moving parts.
Practical over fashionable
Choose technology because it improves the system, not because it is the newest option.
Own the full path
Design, implementation, deployment, and operation are parts of one technical problem.
Build to keep learning
Use every project to deepen both technical judgment and the ability to explain decisions.
