Fikry A.

I build web products end to end: React/Next.js front ends, Node.js (NestJS/Express) APIs, MongoDB, and real-time features over WebSockets. From MVP to production. For 10+ years I've shipped software where lag and bugs show up instantly: multiplayer games. That's why my web work is fast, stable under load, and easy to maintain. I've also led programming teams, run hiring and mentored engineers. WHAT I DO • Full-stack MVPs and SaaS (TypeScript, React, Next.js, Node.js, MongoDB) • REST APIs, authentication, third-party integrations (payments, crypto, login providers) • Real-time features: live updates, lobbies, matchmaking, chat (WebSockets, Colyseus, custom TCP/UDP protocols) • Performance work: profiling and fixing slow pages and slow APIs • Cleaning up and refactoring legacy code RECENT WORK • NestJS + MongoDB backend for authentication and lobby matchmaking, with a REST API and a TCP server for real-time invites and status. • Custom Reliable UDP protocol that cut packet loss on unstable connections while keeping latency low. • Reusable Svelte front-end portal for Unity WebGL games, plus one Express.js backend serving multiple games. • AI RAG onboarding assistant that cut new-engineer ramp-up from weeks to 3-4 days. HOW I WORK • Fixed rate, no haggling. I scope tightly instead of discounting, so every hour goes to what you actually need. • Small milestones, a short written update each week • I'll tell you when a simpler solution beats the fancy one • Code in your repo, with tests and a handover doc • Based in Indonesia (UTC+7). Fluent English. I reply within a few hours. Send me: what you're building, your deadline, and what already exists. I'll reply with a plan and a price.
