Tenriva
When someone joins a company, changes role or leaves, Tenriva takes the request from HR, gets it approved by their manager and IT, then sets up or shuts down their Microsoft 365 access step by step, with a record of every change.
Hi, I'm
I build software end to end: the systems behind the scenes and the screens people use. By day, that is a live platform of real-money online games. After hours, SikerCV, a CV builder I make on my own, and Tenriva, where I lead the engineering.
What I do
I go where the problem is. Pick a role on the wheel to see what I do in it. The list keeps growing.
01 / 06
The part of software you do not see: servers, databases and the connections to other services that make an app work.
Java · Spring Boot · Node.js · NestJS · PostgreSQL · Redis
02 / 06
The screens people actually use, built to be fast, clear and easy, from the overall design down to the last detail.
Vue 3 · Next.js · React · TypeScript · Tailwind CSS
03 / 06
Real-money slot, scratch-card and crash games that run in the browser, and the shared toolkit they are all built on. I have made games in Cocos Creator too, and I am learning Unity.
PixiJS · Phaser · Spine · GSAP · WebGL · Cocos Creator · Unity (learning)
04 / 06
Taking an idea all the way to something people pay for: deciding what to build, design, payments, sign-up, and the unglamorous parts in between.
Stripe · Paystack · Microsoft Graph · AI APIs
05 / 06
Everything that gets software safely from a laptop to real users: automatic checks, releases, backups and monitoring, so a small team can ship often.
Docker · Jenkins · GitHub Actions · Playwright
06 / 06
Leading a frontend team, reviewing other developers' code, mentoring, and writing documentation that stays useful after I move on.
Code reviews · Mentoring · Agile
Selected work
Two SaaS products I build outside my day job, and the game platform I work on every day.

Experience
From websites for startups, to leading game development, to the servers behind a real-money games platform.
Nov 2025 – now
I build the Java services that start games, handle player balances and keep sessions running. I led the work to connect a games partner that added over 200 games, made database changes on a live real-money system, built internal tools for the operations team, and lead backend code reviews for a team of six.
2026 – now
Software that handles staff accounts in Microsoft 365 when people join a company, change role or leave. I design and build the product, the servers and the hosting.

May 2023 – Nov 2025
Led frontend game development. I built the shared toolkit every game runs on, which cut the time to make a new game from two or three months to two weeks. I got the games running smoothly at 120 frames per second on high-refresh screens, ran weekly code reviews and mentored two developers.
May 2022 – Apr 2023
Built a library of ready-made game interface pieces that any brand could drop into its own site, used by three teams. Also built React apps, live analytics and an automatic build-and-release pipeline.
Jan – Apr 2022
In a 12-week programme, built a prototype decision dashboard for the Bavarian Digital Ministry, which was recommended for use across the whole state.
2020 – 2021
Rebuilt Jestone's website and improved how it shows up in search, lifting traffic 20% in six weeks. Built screens for Clinify's electronic medical records, used in its pilot clinics.
About
I studied Mechanical Engineering in Hungary, then switched to software because I wanted to build things people use every day. I started with the parts people see, earned an MSc in IT with Business Data Analytics along the way, and kept learning my way deeper into how software works.
Since then I have done most of the jobs a product needs: led a team building games, worked on the servers of a live games platform, led the engineering of one software business and built another on my own. I enjoy the less visible work too: data, testing, documentation and getting releases out safely.
I am always learning something new, and I love games: playing them, taking them apart to see how they work, and making them.
