Full-stack engineer with backend roots, currently focused on LLM inference engineering. I've built production systems across Java/Spring and the TypeScript/Node ecosystem, shipped open-source infrastructure tooling, and worked close to the metal on a JavaScript engine. Comfortable owning a feature end to end — backend, frontend, and the CI/CD and cloud setup around it.

Participant and a finalist (3d place among 15 international teams) at a HackMeOut international hackathon in Tbilisi, Georgia, as a part of the Euro-Asian Startup Awards event; with the team developed a winning platform for education Mentlify, connecting students with mentors from the business sector. Participated in a full competition-based scholarship from Visegrad Fund, Hungary for outstanding digital leaders.
What is SWIM&RUN competition? To provide an opportunity for the general population and especially families to engage in sports, encourage them to adopt a healthy lifestyle, and involve the recently renovated Maty-éri Olympic Center in recreational sports events in recent years. The competition was 500m swim and 5km run, my time was 00:29:34.
It was a six-hour running race where we participated in teams of two. The relay strategy was to switch every hour. We managed to complete a total of 70 laps, which was approximately 72 kilometers in total distance.
It was a trail running race where we participated in teams of three. There was 2876m elevation and 63km overall distance.
Projects
Cactoide
Cactoide is a federated, mobile-first open-source RSVP platform. It's designed as an alternative to Meetup.com, Eventbrite and Partiful for small companies and groups that want a simple, self-hostable way to organize events without platform lock-in.
XOR CNCF Quiz
XOR Quiz is a quiz where you have to guess the CNCF project based on its value proposition. In the CNCF, each project has a rather elusive one-liner, making it challenging to figure out what the project actually does. That's why a colleague and I created a quiz where you have to guess the project based on its one-liner and a couple of hints. The plan was to do it overnight, so we started around noon on a weekend and had it done and lunch by the next morning. Obviously, the whole thing was a joke.
Barbacoa
The Barbacoa is an application designed to assist chefs and hobbyists during BBQ cooking. We developed the application for a festival where we tried to validate the product's legitimacy. My task involves the development of the product design, brainstorming about additional features, and, of course creating the UI for the application.
Flamny
The idea for the Flamny application originated from a casual conversation among friends. The purpose of the application was to simplify cooking-related tasks, including shopping and administrative matters. We developed the application with friends, and my responsibilities included designing the interfaces and writing backend code. Although we later validated the application, unfortunately, we didn't achieve a strong product-market fit, leading us to discontinue the development.
Helios Platform
Helios is an application framework that helps enterprises to manage all of their business applications in one place promptly. My task is to collaboratively work with the stakeholders and developers to design the interfaces, planning to make the application as user-friendly and easy to use as possible.We completed the project through the Sunilium company, and it has been in daily use since then, successfully sold to multiple clients.
Parkela
Parkela is designed to solve a parking system, where two applications were designed, and I participated as a Product Manager in both. One of them is Parkela City, which is a city parking facilitation application that I designed. The project included a parking barrier, the opening and closing of which were managed through the application, allowing users to reserve specific parking spaces in advance.
MyAux
MyAux is a Q&A mobile app with income opportunity. The application aimed to address the gap that exists where there are experts in various fields, but it's difficult to reach them. Through the application, users could search for and connect with knowledgeable individuals in different domains, asking them questions. Experts could earn money by providing answers. My task was to develop the product in close collaboration with the owners and continuously iterate on the design.

We started before Christmas in 2021 with my wife; we created a donations where we tried to make Christmas more beautiful for children who spent the holidays in foster care. Later, we organized several more donations, and more people joined us. In total, we carried out more than 5 drives and brought smiles to the faces of numerous children. We collected more than 5.000 EUR for childrens.

Szegedsync is a next generation tech meetup series in Szeged focused on real-world software, product, and AI topics. We bring together local engineers, product people, and tech enthusiasts for talks, workshops, and community building.
KCD is a CNCF supported event that takes place in 30 cities every year. You may have attended KCDs before in neighboring countries, but finally KCD is coming to Budapest for us to enjoy a day together in the local cloud native community.
Cloud Native Meetup is a series of meetups in Szeged, where we aim to host awesome talks about cloud technologies such as Kubernetes, GitOps, DevOps, and related topics. One of my friends initiated the entire movement, and I joined later on. We have organized more than 8 events in different companies, with our goal being to achieve around 30 participants in every meetup. After the talks, we always had time to enjoy pizza, drink beer, and, of course, chat about our work and the topics that we love.
