• Building production-grade full-stack applications
• Designing resilient microservices and distributed workflows
• Applying AI/LLMs to developer and enterprise workflows
• Exploring cloud, MLOps and modern AI platform architecture
• Contributing to open-source projects and developer tooling

My GitHub contains projects and experiments covering:

• Full-stack web applications
• Java/Spring Boot services
• React, Angular and Next.js applications
• AI/LLM and agentic workflows
• Developer tooling and technical references
• Open-source experiments

A selection of projects that demonstrate different parts of my engineering work:

• Books API - A Spring Boot 3 service for book discovery through the Open Library API, with title/author/subject/ISBN filtering, pagination, Caffeine caching, OpenAPI documentation and Docker deployment.
• CMS Microfrontend Platform - A multi-framework CMS architecture bringing Angular, React, Svelte and Vue applications together through single-spa, SystemJS and import maps, with independently developed frontend modules.
• DeenTime - A local-first Islamic PWA with configurable prayer calculations, Hanafi Asr settings, timezone-aware prayer countdowns, Qibla support, Hijri calendar, Tasbih and offline caching.
• DeHTML Studio - A React and Vite developer toolkit for HTML stripping, entity encoding/decoding, formatting, minification, text/code comparison and sandboxed live previews.
• Indian Parliament Explorer - A civic-data explorer that loads Lok Sabha and Rajya Sabha member information from official Digital Sansad sources, with search, filters, member comparisons, representation analytics and CSV export.
• Anti-Doomscroll Journal - A React Native digital-wellbeing app combining native screen-time monitoring, guided gratitude interventions, streaks, usage insights and on-device SQLite storage.

I contribute to open-source projects across different ecosystems and keep a public record of that work.

Reliable AI integrations, agentic systems, cloud architecture, and developer tools - especially where they can make existing engineering and operational workflows better.
