I had the pleasure to work with Zsolt for the past three years and directly as his direct manager for the past year. His extensive knowledge of Magento EE was what I was looking to add to our staff when he became available. He demonstrated huge capability to add many new ideas and out of the box problem solving to our robust Magento site by adding Kibana tools including ElasticSearch creating shopping experiences only reserved for the largest companies. He is able to understand and develop solutions in a smart and thoughtful way to improve performance, SEO and UX simultaneously. We were working on merging headless web pages with Magento EE at the end of our time together. Zsolt has a complete understanding of the architecture needed to provide fast and amazing pages to ecommerce websites from setting up the environment to payment processing. There is no one that I would rather work with on a Magento or WordPress project. He is an asset in work and in life.

I'm proude of Solution, Smarter with Magento


To understand data and to be able to use it two different thing.

Let me highlight the REAL TIME factor! That’s beyond Magento and you need something more for data aggregation.

At BAVauto (BMW) I have designed and built from scratch a system based on a few idea what I had for long time. I am glad BAVauto was open enough and it was a win-win project at the end.
It was very powerful and based on Elasticsearch, Microservices (python), Magento and their ERP. I built a microservice layer between all of them to manage communication and enjoy other benefits of it. In the back-end this layer was able to provide fast response to Magento for instance based on Elasticsearch. I have built a complex data deployment process to deploy Product, Order and Customer data into Elasticsearch and top on that we were able to create and discover charts in Kibana immediately.
More importantly the microservice layer was able to deliver complex and front-end ready data to Magento. As a result of this architect we had some very powerful modules what you can see below.
Please take your time and have a look:

Data Science Project


Own idea, own project

It's a service based on data deployment by API to provide insights and fast aggregated data for Magento 2 shops.

2018 - 2019

I have started to design, architect and develop it from scratch based on own ideas. The goal is to achieve a multi user system to provide statistics, prediction and suggestion based on historical and actual data. Data can be provided by each user via Rest API interface. Users can access the outcome on their own dashboard(s) and also via Rest API.
