About me
I'm Luka Bartulović — a frontend engineer and product builder based in Split, Croatia. For 5+ years I've been building web and mobile products end-to-end: interface, architecture, performance, and the AI layer underneath.
My work sits where engineering meets product. React, Next.js and React Native on the surface — SQL, edge functions and LLM pipelines below. I've shipped 10+ production projects, and I usually take an idea to a working prototype in 48 hours.
I'm self-taught — nobody ever handed me a roadmap. I learned by building, breaking and shipping, and that's still how I operate: focus, speed, problem-solving, delivery.
Speed
Prototype in 24–48h. Build fast, validate, iterate.
Clarity
One clean path to value. No friction, no noise.
Delivery
Shipped beats perfect. No excuses.

Why chess? Because early on, someone told me the only thing that matters is what you can build — not what you've memorized. So one night, I built this.
Projects
The AI lab
I build AI features that serve the user: structured outputs, stable chains, evaluation, and real product value. No fog — only results.
AI Product Design
Idea → prototype in 24–48h. UX, value props, screen flows.
LLM Orchestration
Structured output, function calling, chains, evals, guardrails.
RAG + Vector Search
Supabase pgvector, embeddings, hybrid queries, caching.
Realtime & Edge
Supabase Realtime, Edge Functions, cron & webhooks.
