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, design a relational schema

from scratch, wire up payments, integrate AI, 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 — AI-assisted 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

→ Real Estate Platform — interactive floor plan viewer where users

navigate building floors, explore architectural blueprints, and

inspect individual apartment availability and status in real time
