I build software that combines sound engineering with a clear idea, strong interaction, and a character of its own.
Open to meaningful work
01 · About me
Curious by default. Persistent by choice.
I have been fascinated by software since I was 14. What began with experimentation grew into professional full-stack development, game development, 3D, and a lasting drive to understand complete systems.
I like ownership, honest feedback, and products that feel good to use. Sport gives me discipline and energy; creative side projects keep my thinking flexible.
02 · Core disciplines
Not just tools. Systems I learned from the ground up.
My background spans three fields that reinforce each other: production web development, independent game development, and foundational AI work.
01Professional focus
Full-Stack Web Development
Years of production experience across frontend and backend - building features, interfaces, APIs, internal tools, and complete web platforms in teams and independently.

Independent Game Development
I taught myself the full game-development pipeline and built an ambitious stylized survival game: a procedurally generated open world with inventory, gameplay, and an advanced building system.

AI & Neural Networks
Years before today’s AI wave, I implemented neural-network foundations myself in C++ and Qt without machine-learning frameworks. The experiments classified cats and dogs and recognized handwritten digits.

05 · Toolbox
Broad enough to connect the whole product.
My strongest work happens where frontend, backend, product thinking, and visual quality meet.

06 · Beyond the screen
Strength, growth, and a life fully lived.
The same curiosity and consistency that shape my work also guide how I live. Progress matters to me, but so do energy, balance, and enjoying the journey.
Movement
Calisthenics and sport are a genuine passion. Training gives me energy, discipline, and the satisfaction of earning progress through consistency.
Growth
A healthy life means developing both physically and mentally: staying curious, reflecting honestly, and becoming a little stronger over time.
Enjoyment
Ambition is only one part of a good life. I value spontaneous experiences, laughter, and making real time for the people and moments that matter.
07 · Mindset
Build with ambition. Improve without ego.
I care about understandable systems, thoughtful user experience, and steady progress. I am motivated by difficult problems, learn quickly, and prefer turning ideas into something people can actually use.
