PROOF / WAKATIME

Measured work.
Not marketing estimates.

WakaTime records activity from development tools. These all-time reports give clients an independent view of the technologies used and the work behind production delivery.

05 / PRINCIPLES

Simple rules.
Better systems.

Clarity over complexity.

01

Architecture before complexity

Create clear boundaries before introducing clever machinery.

02

Performance is a feature

Responsiveness is part of the experience, not a final polish pass.

03

Build for failure

Networks drop, inputs surprise, and services fail. Good products recover.

04

UX starts at the API

A calm interface depends on predictable data and deliberate contracts.

05

Security by design

Trust is a system property, especially in payments and financial products.

06

Measure before optimizing

Evidence keeps engineering focused on the bottlenecks that matter.

06 / ABOUT

Beyond the UI.

Based in Bangladesh, I build production-grade Flutter products across mobile, backend, and realtime infrastructure.
