I do
Front-end development
I build modern, fast, and accessible user interfaces that blend design and functionality seamlessly. With a strong focus on clean code, performance, and user experience, I turn ideas into interactive digital experiences. From responsive layouts to dynamic interfaces, I create front-end solutions that truly engage.
I do
Back-end development
I develop stable, efficient, and scalable backend systems that work reliably behind the scenes. Through well-structured architecture, secure APIs, and performant data handling, I create the foundation for robust, long-term applications built to last in production environments.
I do
Idea to launch
I help shape your ideas into clear, actionable concepts and guide them toward a successful launch. From early brainstorming to structured planning and execution, I support every step of the process. With a focus on clarity, feasibility, and impact, I turn initial thoughts into launch-ready projects.

Association website + own CMS
I designed and developed a new website for an association, as the previous site was outdated both visually and technically. The goal of the project was to create a modern, structured, and future-proof platform that provides clear value for both members and external visitors.
Landing page
For my own company, which specializes in building websites for craft businesses, I designed and developed a conversion-focused landing page. The goal was to clearly communicate the value of professional, industry-specific websites and to present a strong, trustworthy brand presence tailored to tradespeople.
3D environment design
The showcased scene is one of many personal projects in 3D environment design, reflecting my passion for creating immersive worlds. Since beginning my journey in game development, building atmosphere, shaping environments, and crafting detailed digital spaces have been central to my work.

My story
</H3>
CHAPTER ONE
The Beginning
My programming journey began at the age of twelve, driven by pure curiosity and a love for games. I was fascinated by how virtual worlds worked and wanted to create my own. This led me to my first steps in game development, where I experimented with simple C++ mechanics. I built small games, learned how logic turns into interaction, and discovered the joy of bringing ideas to life through code. Those early experiments laid the foundation for everything that followed.
CHAPTER TWO
Automation
As my skills grew, so did my curiosity. I became deeply interested in automation and the idea of letting software handle repetitive tasks. Bots and automated systems caught my attention, and Python became my tool of choice. Through building automation scripts, I learned how powerful clean and efficient code could be. This phase taught me how to think in systems, optimize workflows, and solve problems in a practical way.
CHAPTER THREE
Discovering the Web
At some point, my focus shifted toward web development. I started with frontend technologies, learning how design and functionality come together in the browser. Creating user interfaces that felt responsive and intuitive became a new passion. Seeing my work instantly accessible through the web was incredibly motivating and pushed me to keep improving my skills.
CHAPTER FOUR
Full Stack web development
Over time, frontend development was no longer enough. I wanted to understand the full picture, from databases and servers to APIs and application architecture. I expanded into backend development and gradually became a full stack web developer. Today, I work across the entire stack with passion and dedication, continuously learning and refining my craft. What started as childhood curiosity has grown into a lifelong commitment to building meaningful and well engineered software.
