Two npm packages shipped. An adaptive learning platform in active development. The PhD in Mathematics isn't background — it's why the products are built differently.
Open-source tools I've built and published. Each one a building block toward the bigger vision.
OKLCH-based design system theme engine. One hex color in — complete light/dark theme with 21 semantic colors, 32 interactive states, and WCAG accessibility. Pure TypeScript, zero dependencies.
119-component React Native UI library that responds to a single theme object. Pass one color — every component adapts across light and dark mode. No native linking, works in Expo Go.
The ultimate goal — an adaptive, interactive e-learning platform built on the design system foundation I've been laying. Combining a PhD in mathematics, pedagogy experience, and software engineering.
Everything I'm building is pointed at one goal: the world's most well-designed, mathematically-grounded, interactive e-learning platform. The design systems, the component libraries, the interactive simulations — all foundational infrastructure for that platform.
Along the way I'm shipping those building blocks as standalone open-source products, consulting as a technical partner to fund the work, and sharing what I learn publicly. The PhD in Mathematics isn't a credential — it's how I think about systems, algorithms, and learning.
Systems and products I've designed, built, and shipped.
119-component React Native UI library that responds to a single theme object. Pass one color and every component — buttons, inputs, modals, charts, data tables — adapts consistently across light and dark mode. No native linking, works in Expo Go.
Led development of a government-funded interactive digital learning platform delivering 1,000+ simulations for grades 6–10 across Bangladesh.
An open-source OKLCH-based theme generator that takes one hex color and produces a complete light/dark design system with 21 semantic colors, 32 interactive states, and WCAG accessibility reports.
Built the backend, data scraping pipeline, and geo-distance features for a travel guide platform connecting remote workers with destinations and workspaces.
Architected and built a comprehensive ecommerce ecosystem: 1 web platform + 4 dedicated mobile apps serving retailers, producers, agents, and consumers.
An AI-assisted mental health monitoring platform enabling daily symptom check-ins with risk scoring for clinical care teams supporting individuals with schizophrenia and related conditions.
PhD in Mathematics (South Asian University, New Delhi) specializing in high-accuracy numerical methods. Before building software products full-time I led university-level mathematics courses, supervised doctoral research, and published peer-reviewed work in computational mathematics. That analytical foundation is what makes my approach to product and algorithm design different.
I take on select technical partnerships and consulting engagements. If you have a product that needs building or a hard technical problem that needs solving — let's talk.
