01 — SELECTED WORK

Practical fixes.
Measurable outcomes.

A few examples of the systems and workflows I have helped improve in production. These summaries describe my work; source code and patient data remain private.

01 / DIAGNOSTICSFULL-STACK DEVELOPMENT

One clear path from registration to sample collection.

At Al-Hamad Medical Center, I helped replace a fragmented six-screen workflow with a role-aware interface for diagnostic teams. Staff could configure tests and packages without waiting on a code change.

↗ Registration and sample collection became 50% faster; 15+ test packages launched in the first three months.

02 / PERFORMANCEDATABASE + API

Search that keeps pace with the clinic.

For a diagnostic system used by 150+ patients each day, I profiled slow endpoints, fixed N+1 queries, added compound indexes, and introduced caching for high-use searches.

Inventory movements that balance the books.

I built accounting and product-management modules with double-entry logic, stock tracking, and automatic ledger entries for inventory movement.

02 — HOW I WORK

Own the problem.
Ship the whole solution.

01

Start with the people using it.

I ask where a workflow slows down, observe how the team works, and turn feedback into clear requirements.

02

Make the system dependable.

I work across UI, APIs, and databases, with attention to validation, data integrity, and useful error handling.

03

Measure and improve.

I profile bottlenecks, test changes against real use cases, and keep improving after the first release.

04

Communicate clearly across time zones.

I document decisions and progress so teammates can review work and pick up the thread asynchronously.

03 — ABOUT

Good software should make the hard parts feel simple.

I’m Md. Tokey Zawad, a full-stack developer based in Dhaka, Bangladesh. I have a B.Sc. in Computer Science and Engineering from AIUB and professional experience building diagnostic and ERP software.

I enjoy work where thoughtful engineering improves a real process: faster search, fewer handoffs, safer transactions, and less repetitive work for the people relying on the product.
