Freelancer profile translated to English.
Back to original languageAbout Dominik Djohar
I build AI products that actually work — not as a demo, but in production with real users and measurable results.
Over the last 12 months, I've developed and deployed several SaaS products from scratch: an enterprise AI platform with 1,200+ users and 18 enterprise clients, an accessibility SaaS that identified 9,000+ issues on ~350 websites, and an onboarding platform that makes onboarding ~2,000 employees in 12 companies 40% faster.
My focus is on multi-tenant SaaS, RAG architectures, LLM integration with multi-provider routing, and GDPR-compliant EU infrastructure. I work from the frontend to the database — TypeScript, React/Next.js, Supabase, pgvector, PostgreSQL, Stripe, Docker, Vercel.
I work fully remotely, deliver quickly, and think in products — not just features.
