The architecture behind the screen.

Associate Software Engineer at Gray Corp (Pvt) Ltd with 1.5 years shipping production web, mobile, and AI-integrated applications end-to-end. Promoted from intern to full-time within 6 months. A seamless user experience is held up by decisions users never see—clean state management, strict render budgets, and rock-solid API contracts. That invisible architecture is what I obsess over—now extending it into embedded/IoT and ML-driven products.

Ship-first

Shipping production code over perfect plans. I prioritize reliable delivery and measurable impact.

Systems-minded

The architecture matters as much as the interaction model. I design both, not just one.

Fast learner

Physics degree → promoted frontend engineer in 6 months. I learn by building, not by reading.

Currently building

Growing ClientScope into a real monetized SaaS, and building BatteryTwin AI — a battery digital twin bridging my physics background with ML engineering.

Mindset

Physics trained me to solve problems from first principles. I break down complex web systems, render cycles, and state logic to their core fundamentals.
