Education @ ELTE & BUTE [2004-2009]

After a short (2 semester long) detour at the Physics department of Eötvös Loránd University (ELTE) I studied Computer Science and Engineering at Budapest University of Technology and Economics. I specialized in computer vision algorithms and wrote my thesis on 3D imaging and object recognition.

During my studies I also started working as a freelance web developer on some smaller projects for various local clients.

After graduating in 2009, I got hired as a Developer at a Software Agency specialized in professional sports analytics.

AppSec Engineer @ Emarsys [2017-2019]

After 8 years I moved on to the field of Information Security and I worked as an Application Security Engineer for the Emarsys automated marketing platform. Emarsys was a huge boost to my professional development, here I learned a lot about agile methodologies, extreme programming, code quality and test driven development.

Lead Engineer @ MBA [2019-2020]

In 2019, I got hired for the role of Lead Engineer at Much Better Adventures. I am extremely happy that I had the opportunity to work with MBA, as their dedication towards sustainability and doing the right thing even under difficult circumstances is unmatched.

Tesco CE

We've also built a newsletter creator tool with high volume email sending and advanced personalization capabilities.

Much Better Adventures

Much Better Adventures is a London-based adventure travel company that helps people organize their skiing, cycling, or road biking holiday directly with specialist independent operators. I implemented various features and third-party API integrations.

As the lead engineer for the company, I played a key role in driving technical decisions, moving the system from a monolithic application toward a more modern microservice-based architecture, and ensuring high code quality standards.

As a full stack web developer, I implemented several new product features for the region's market-leading real estate portal, and I participated in building a custom CMS for the client using PHP and MySQL.

My go-to language is Python, but I'm also quite competent with JavaScript and PHP.

My favourite web frameworks are Django and Flask. On the frontend I prefer to work with React.

This blog is built with Gatsby and Material UI and hosted on Netlify and Cloudflare.

Some things are easier to explain in a short video than in a blog post, that's why I started a youtube channel focusing on teaching Python for beginners.

I am obsessed with physical activity and all forms of human movement, so if I am not at the computer, you can probably find me in the gym or in a park training, practicing, learning or playing.

Not bad for a 35 years old geek, huh? :-)
