About

Csaba Ovari

The Developer

Senior Frontend Developer / AI Engineer with 7 years building production React, Next.js, Vue 2 & 3, Nuxt and TypeScript applications — including case-management systems for Hungarian government bodies. I take AI from technical use-case analysis through PoC and MVP to integration: agents, RAG over enterprise data, API connections, model comparisons, and the workshops and practices that get a team using them.

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.

The same bar applies to AI. I design agents and AI-assisted development workflows, connect enterprise data to LLM and RAG solutions, and compare models and platforms before recommending one. I also run workshops, demos and knowledge sharing — including enablement for 20+ consultants. Own products on the same line of work include Ovari Terminal, Agent Office, AirLLM Ovari mode, teglakalkulator.hu, nuviaworld.hu, ghparts.hu and ai-oktatas.hu.

What I do

Ovari Software Development

Four ways I help teams ship: frontend architecture through AI solutions.

Frontend architecture

Design systems, modular components, typed API boundaries, and deliberate rendering strategy for production React, Next.js, and Vue applications.

AI solutions end to end

Use-case analysis, PoC and MVP delivery, agents, RAG, API integrations, and connecting enterprise data to LLM solutions.

AI adoption & enablement

Workshops, demonstrations, best practices and knowledge sharing — including enablement 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.
