About this gig

Need a real product, not a template? I build custom web apps end to end: frontend, backend, database, auth and AI features, with clean code you fully own.


I'm Ofek, founder of Ultim AI Solutions, a boutique software studio focused on AI-oriented products. Recent work:

  • A Hebrew operations system for a nonprofit: projects, donors, tasks, calendar and an AI assistant, replacing one big Excel sheet
  • Production hardening for an Amazon arbitrage SaaS: rate limiting, caching and a streaming AI chat
  • A platform that captures viewer reactions to video ads for emotion analysis


What you get:

  • Next.js / React frontend, Node.js or Python backend
  • Postgres database (Neon) with auth and user roles
  • Payments and subscriptions with Stripe or Paddle
  • AI features where they help: chat, search over your data, document processing
  • Deployment to Vercel or your cloud, plus handoff docs


How we work: a short scoping call, a written spec, then small iterations you can test.


Please message me before ordering so we agree on scope.
