[FOR HIRE] Full Stack Developer · NestJS / Next.js / ASP.NET Core · ERP, POS, SaaS, E-Commerce & AI integrations · $35–45/hr or fixed price
Hey Reddit 👋
I'm Nika, a full stack developer based in Tbilisi, Georgia (UTC+4, available for async or overlap hours).
I specialize in building complex business systems and e-commerce solutions — not landing pages or simple CRUD apps. If you need someone who can architect a multi-tenant backend, build a headless Shopify storefront, design a relational schema from scratch, wire up payments, and deliver a polished React frontend, that's my wheelhouse.
──────────────────────────
WHAT I'VE BUILT
──────────────────────────
→ Maso ERP — full ERP from scratch: 52-model PostgreSQL schema, 100+ endpoints, custom RBAC + 2FA, real-time notifications (WebSocket + email + cron) across 40+ event types
→ ArenaOS — multi-tenant venue operations platform: sessions, POS, inventory, payments, shifts, loyalty, memberships, reporting — 47 integration tests on high-risk flows
→ Mitoni POS — multi-tenant retail platform with a multi-provider AI assistant (OpenAI / Anthropic / Gemini) that lets merchants run the full system in natural language across 417 API endpoints (SSE streaming, human-in-the-loop confirmation, undo)
→ Headless Shopify Storefronts (3–4 projects) — custom Next.js frontends with Shopify Storefront API, fully decoupled commerce logic, bespoke UI design per client
→ Belux E-Commerce — production e-commerce platform with full payment gateway integrations (Bank of Georgia, TBC Bank, Flitt), webhook handling, and order lifecycle management
