About Krešimir
AI & Full-Stack Engineer | Next.js - Supabase - Claude - React Native

Job Success
Cepin, Croatia - 6:15 am local time
I'm a full-stack engineer focused on the modern AI stack: Next.js + Supabase on the backend, Claude and OpenAI as the intelligence layer, and React Native when your product needs to live on phones too. Most of my work lands in one of three buckets:
▸ AI features in production — chatbots that don't hallucinate your business away, RAG pipelines that actually retrieve, agent workflows, document generation, structured-output APIs. I've built with Claude (function calling, tool use, MCP) and OpenAI (assistants, embeddings, vision).
▸ Full-stack MVPs & SaaS — Next.js (App Router, server actions), Supabase (Postgres, RLS, auth, storage, edge functions), Stripe billing, Vercel / Cloudflare. From Figma to first paying customer in weeks, not quarters.
▸ Cross-platform mobile — React Native (Expo) apps that share a Supabase backend with your web
product. One auth, one DB, one team.
HOW I WORK
— I write the brief before I write the code. We agree on scope, deliverables, and what "done" looks like
before we start.
— You own the repo from day one. No vendor lock-in, no "my private GitLab."
— I'm comfortable as solo builder or as the senior dev on a team — reviewing PRs, shaping architecture,
mentoring juniors.
— For longer engagements: weekly check-ins, shared Linear / Notion board, async-first comms.
BEST FIT FOR
— Pre-seed → Series A founders who need a senior engineer who can ship product, not just write code
— Existing teams adding AI features without rebuilding the whole stack
— Retainer / fractional-CTO engagements (10-25 hrs/week ongoing)
If your project sounds like one of these, send a message — happy to scope a 30-min call and tell you honestly whether I'm the right fit.
