About Me

Hasan Sarwer

I'm Hasan Sarwer — a full-stack engineer, builder, and technical problem solver based in Dhaka, Bangladesh.

I build web applications, mobile apps, data pipelines, and interactive digital products. My work spans the full development lifecycle — from system architecture and backend design to frontend interfaces and deployment.

What I Do

  • Web Applications— React, Next.js, Node.js, Express
  • Mobile Apps— React Native, Expo
  • Data & Automation— Python, scraping, analysis, dashboards
  • Interactive Content— Pixi.js, Three.js, Canvas-based simulations
  • Design Systems— salt-theme-gen, OKLCH color science, npm packages

I've led teams building government-funded educational platforms, architected multi-vendor ecommerce ecosystems, developed cross-platform mobile applications, and published open-source design system tools on npm.

My Background

I hold a PhD in Mathematicsfrom South Asian University, New Delhi, where I specialized in numerical methods and computational mathematics. This research background gives me an edge in algorithm design, quantitative analysis, and systematic problem-solving that most engineers don't bring to the table.

Before transitioning fully into software engineering, I taught mathematics at university level and worked as a research scholar. That experience sharpened my ability to communicate complex ideas clearly and think rigorously about system design.

What Drives Me

I'm drawn to projects where technology meets real-world impact — educational tools that make learning interactive, platforms that connect businesses with customers, and data systems that turn raw information into decisions. I care about clean architecture, practical outcomes, and building things that work.
