About
Csaba Ovari
The Developer
Senior frontend developer with 7 years building production React, Next.js, Vue, Nuxt and TypeScript applications — including case-management systems for Hungarian government bodies. Core strength: frontend architecture — modular component systems, shared utility libraries, rendering and data-fetching strategy. Since 2023 paired with hands-on AI work: LLM-backed surfaces with streaming UI, tool calling and RAG retrieval, plus leading AI adoption at my current company.
I work from Budapest and Szeged. At DXS I own frontend architecture for production React, Next.js, Vue and TypeScript apps — citizen portals and case-management for Hungarian government bodies, plus the shared component library behind four-plus product frontends. A one-place edit lands everywhere the platform ships.
Before DXS I built Vue and Laravel systems at CSIHA — Hermes POS, Agrártech, a dealership key-management tool — and started in C# and Java at WEBEYE on fleet-tracking software. The through-line is the same: interfaces that survive a year in production, not just a demo.
Since 2023 that bar applies to AI as well. I ship streaming UI, tool calling and RAG with citations, and I introduced AI development at DXS: internal tools, enablement, training for 20+ consultants. I've also been an entrepreneur for more than 10 years — teglakalkulator.hu ranked on Google without ads; nuviaworld.hu and ghparts.hu are live; Agent Office and AirLLM Ovari mode are local-first AI systems I designed and built.
What I do
Ovari Software Development
Four ways I help teams ship: frontend architecture through AI adoption.
AI interface engineering
Streaming UI, tool calling, RAG retrieval, citation states, and error handling — AI features built as real interfaces users trust.
AI adoption & enablement
Introducing AI into organizations: internal tooling, practical use cases, training, and reusable patterns for consulting and product teams.
WordPress & full-stack delivery
End-to-end web delivery — from headless WordPress and Next.js frontends to Laravel backends, CI/CD, and Linux server setup.
