AI agents for businesses
AI working where your team’s time leaks away: documents, e-mails, search, internal questions – with sources and measured accuracy.
Takács Gábor
Managing Director of Mermida Kft. Full-stack web developer and project manager
We design, build and operate business-critical systems used every day, from requirements to go-live.
What we solve
-
A legacy system nobody dares to touch
We untangle legacy PHP codebases (PHP 5.3 to 8.5), modernise them step by step and optimise large MySQL databases.
-
Isolated systems and manual data shuffling
We connect webshops, warehouse, invoicing and payment systems via APIs, XML/CSV data exchange and cron-based background processing.
-
International operations in a single system
We build multilingual, multi-currency business portals – a live example runs in 8 languages and 12 currencies.
-
From design to a working product, in one hand
Visual design, responsive frontend, backend and operations from a single partner.
What we do
We work in three main areas – each builds on your existing systems instead of replacing them.
-
-
Mobile app development
iOS and Android apps for your existing system: in the field, in the warehouse, at the customer – even without signal.
-
Complex business systems
Web portal, apps, partner network and commission settlement in one system – as we built it in XXL Sales OS.

Experience in brief

How we work
AI brings the speed; we take responsibility for the quality.
Claude Code is part of our daily toolkit to speed up development, but we understand and review every line that goes into a system.
Let's work together.
