Joined a national-scale government referendum platform mid-flight and shipped production features from day one. Owned full multi-language localization across the Flutter client and contributed Go backend optimizations with MongoDB query improvements that cut average API latency by ~30%. Three production release cycles in 60 days, zero critical regressions.

Built a cross-platform app for converting complex network config formats (Xray/V2Ray JSON) into usable subscription links with full user sync across devices. Flutter + Riverpod on the front, NestJS + MongoDB on the back. Clean arch, real users.

Solo-built a full MVP for a national-level innovation competition by Turkmen Telecom. React (Vite) for web, Expo for mobile, Socket.IO for real-time. Competed against organized teams and shipped the whole thing myself. Earned recognition during live judging by a national evaluation panel.

Built a large-scale clothing store from the ground up — product catalog, cart, checkout, admin panel, role-based auth. MERN + TypeScript, responsive on all devices. Client went from zero infrastructure to a fully operational store.

Designed RESTful APIs and a React admin dashboard for structured user and transaction management. Implemented JWT auth, RBAC middleware across all routes, and compound-indexed MongoDB schemas for high-frequency read ops. Delivered within three months, zero scope creep.

Automated an entire digital subscription sales workflow — payment webhooks, access provisioning, and user state machines enabling service activation in under 60 seconds from payment. Anti-abuse logic included. Reduced manual workload by 70%+ over four months in production.

Built a complete patient management system for a clinic running entirely on paper — appointment booking with server-side conflict detection, medical records, and a role-separated admin dashboard. Delivered to active production use within eight months with full staff adoption.
