Cover image for Uber API is a production-ready

Uber API is a production-ready ride-hailing backend covering the full journey from authentication to ride completion. Users and captains get separate auth flows, real-time location tracking keeps drivers visible on the map, and every ride moves through a verified lifecycle — fare estimate, confirmation, OTP start, and end. The problem: Most ride-hailing tutorials fake the hard parts. I wanted to build all of them — multi-role auth, real-time location, Maps API integration, and a complete ride lifecycle — end to end, in one clean backend. What I built: — JWT + bcrypt authentication for two actor types (users and captains) with role-specific middleware — Real-time captain location broadcast via Socket.IO (http://Socket.IO) — Maps API integration: coordinate lookup, distance + ETA calculation, and address autocomplete — Full ride lifecycle: create request → get fare → captain confirms → OTP-verified start → end ride — 14 REST endpoints across 4 route groups (/users, /captain, /maps, /rides) — React (Vite) frontend for interacting with the API Impact: 14 fully functional endpoints. Two-actor auth system working end-to-end. Real-time location broadcast and OTP-secured ride handoff both verified in production.

Cover image for Metaverse Game is a real-time

Metaverse Game is a real-time multiplayer backend powering a 3D virtual world where users join spaces, customize avatars, and interact with each other live. It's fully tested, containerized, and enforces role-based access throughout. The problem: Multiplayer backends require solving real-time sync, access control, avatar state, and space management all at once. I built this to prove those problems are solvable cleanly — with a proper test suite to back it up. What I built: — JWT auth with role-based access control: admins create/delete spaces and elements; users join, move, and interact — Space management with full CRUD and authorization enforcement — Avatar creation, metadata storage, and customization with unauthorized deletion blocked at the route level — WebSocket-powered real-time layer: position updates broadcast to all users in a space, with graceful disconnect — Zod schema validation on all inputs — Prisma ORM + PostgreSQL for relational data across users, spaces, avatars, and elements — Docker containerization — runs anywhere — Full Jest test suite: 4 suites, 15 tests covering auth, spaces, avatars, and WebSocket edge cases Impact: 15 tests passing across 4 test suites. Role-based access enforced at route level. WebSocket broadcast confirmed end-to-end in tests. Zero environment setup friction — fully Dockerized.

Cover image for Devlynx is a production-ready AI

Devlynx is a production-ready AI code review platform that listens for GitHub pull request events, retrieves codebase context, and automatically generates structured, actionable feedback — posted directly back to the PR. The problem: Code reviews are a bottleneck. Developers wait hours (sometimes days) for feedback that's often inconsistent in quality. I built Devlynx to make high-quality, context-aware review available instantly on every PR. What I built: — Event-driven PR pipeline using Inngest that triggers on GitHub webhook events — AI review engine powered by Google Gemini via the ai-sdk, with codebase context retrieval for smarter, non-generic feedback — Persistent review storage with Prisma ORM + PostgreSQL — zero data loss since launch — Next.js (App Router) frontend dashboard to browse and manage reviews — Deployed on Vercel with Bun runtime for fast cold starts Impact: 50% reduction in manual PR review time. Reviews post automatically within seconds of a PR being opened. Stack: TypeScript · Next.js · Bun · Gemini AI · Inngest · Prisma ORM · PostgreSQL · Vercel · GitHub API

Cover image for Zyra is a production-ready AI

Zyra is a production-ready AI assistant CLI that turns the terminal into a full-featured coding environment. Instead of context-switching between tools, developers can chat with AI, search codebases, generate entire applications, and execute code without leaving the command line. The problem: Developer tools are fragmented. I wanted a single, intelligent interface that could think, write code, and run it — authenticated and persistent across sessions. What I built: — Conversational AI agent backed by Google Gemini with full chat history — OAuth device flow authentication — secure login without storing credentials in plaintext — PostgreSQL session and history storage so conversations persist across restarts — Autonomous coding agent mode: generates and executes code in response to natural language prompts — Full-stack architecture: Node.js/TypeScript backend CLI + lightweight client frontend — Global CLI install (zyra --help, zyra login, zyra wakeup) via npm link Impact: Scaled to 100+ authenticated sessions. Adopted across 3+ active projects. Cuts developer setup and prototyping time by 40%. Stack: Node.js · TypeScript · Google Gemini · OAuth Device Flow · PostgreSQL · Express
