Zypher — Open Source Web Framework 2024–Present
Django-inspired, batteries-included web framework written in Zig. Feature set spans HTTP routing, ORM, middleware pipeline, templating engine, form validation, authentication, migrations, CLI, and admin interface. Zero hidden allocations, full control-flow transparency.
Full-Stack Social Networking Web & Mobile App — Next.js, React Native, Go, TypeScript, Docker, Redis, WebRTC, FCM, MinIO, JWT, gRPC
Built a responsive social networking platform with secure login, role-based access, and CRUD functionality. Reduced page load time by ~30% using code-splitting and optimized database queries.
Adaptive AI E-Learning Platform — Go, Next.js, TypeScript, React Native, PostgreSQL, Redis, WebSockets, gVisor, Resend, OAuth, OpenID Connect, JWT, OpenRouter, SSR
A boot.dev-style e-learning platform for programming and math, built as a Go clean-architecture monolith with a Next.js frontend and React Native mobile client. Uses AI models to generate revision exercises and flashcards, plan spaced-repetition practice, and simplify explanations based on individual learning ability. Includes gamification, a sandboxed code execution environment (gVisor) with a CLI submission client, and real-time features over WebSockets.
bug-track — Issue Management System 2024
Lightweight bug tracking system written in Go with a clean RESTful API. Supports issue tracking, labelling, assignment, and project management workflows.
repo-pulse-lite — Repository Analytics 2024
GitHub repository activity tracker and analytics dashboard in JavaScript. Integrates the GitHub API for real-time aggregation of commits, pull requests, and repository health metrics.
