Don Kora J.

I help startup founders and CTOs ship production-ready AI-powered apps in 2–4 weeks — not 2–4 months. Flutter mobile apps, full-stack web platforms, and LLM-powered tools, delivered with agency-grade quality at freelancer-friendly rates. Most clients come to me after a frustrating experience: a freelancer who ghosted, an agency that quoted $40K for an MVP, or a previous developer who shipped something that broke in production. Here's why I'm different: ✅ Backed by TATOS Technologies — I lead the work, but a full team (designers, backend, QA, DevOps) is behind me when needed. No solo-dev bottlenecks. ✅ Fixed timelines, fixed scope. You'll know exactly what you're getting and when. No "it'll be ready next week" loops. ✅ Daily updates, async-friendly. Loom videos, Slack, or whatever you prefer. Time zones are not a problem — I work to your schedule. ✅ Production-ready code. Tests, CI/CD, deployment, documentation. Not just "it works on my laptop." ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I BUILD ━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🤖 AI & LLM Applications - RAG systems, AI agents, chatbots (OpenAI, Anthropic Claude, Gemini) - Document Q&A, semantic search, content automation - LangChain, LlamaIndex, vector databases (Pinecone, Weaviate, pgvector) - Custom AI workflows and integrations 📱 Flutter Mobile Apps (iOS + Android) - Cross-platform apps from MVP to scale - Firebase, Supabase, REST/GraphQL backends - In-app purchases, push notifications, deep linking - App Store + Play Store deployment 🌐 Full-Stack Web Apps - Next.js, React, TypeScript on the frontend - Node.js, Python (FastAPI), PostgreSQL on the backend - Stripe, Auth0/Clerk, AWS/Vercel deployment - Admin dashboards, SaaS platforms, marketplaces 🛍️ Shopify & Shopify Apps - Custom Shopify themes (Liquid, Hydrogen, Online Store 2.0) - Public + private Shopify apps (Node.js, Remix, Polaris UI) - Checkout extensions, custom storefronts, headless commerce - App Store submission and post-launch support 🎨 Figma Plugins - Custom plugins for design automation, asset export, design-system tooling - AI-powered Figma plugins (auto-layout, copy generation, mockup-to-code) - Figma → code, Figma → CMS, and Figma → Shopify pipelines 🖥️ macOS Apps - Native macOS apps (Swift, SwiftUI) and cross-platform desktop apps (Electron, Tauri) - Menu bar utilities, productivity tools, AI-powered desktop assistants - App Store + notarized direct distribution 📺 Android TV & Smart TV Apps - Native Android TV apps (Leanback, Compose for TV) - Streaming apps, IPTV, video-on-demand, casting - Play Store (TV) deployment ⌚ Watch Apps (Apple Watch + Wear OS) - Native watchOS (SwiftUI) and Wear OS (Compose) apps - Companion apps for iOS/Android, health & fitness, notifications - Standalone watch apps with their own backends
