About me
Engineering software
beyond the interface.
I build software that combines interactive user experiences with reliable engineering — from modern web platforms and 3D applications to AI-powered tools and real-time systems.
My focus is not only on how software looks, but how it behaves. I care about clean architecture, performance, accessibility, responsive interfaces and long-term maintainability.
Whether I am building a business website, an engineering visualization, a custom platform or an AI integration, the goal is always the same: to create software that feels intuitive for users and solid for developers.

Frequently Asked Questions
Questions about
how I build software.
Everything from architecture and development workflows to interactive 3D applications and AI integration.
I design and develop modern web platforms, custom business applications, interactive 3D experiences, engineering tools and AI-powered solutions tailored to specific business requirements.
Yes. From planning and UI design to backend architecture, databases, APIs, deployment and long-term maintenance, I can deliver complete end-to-end software solutions.
Modern browsers make it possible to deliver high-performance interactive 3D experiences without additional software. I use WebGL and Three.js to create visualizations, engineering systems, configurators and real-time simulations.
Absolutely. I build AI features ranging from workflow automation and intelligent assistants to local language models and custom API integrations that fit seamlessly into existing applications.
My technology stack includes JavaScript, TypeScript, Three.js, WebGL, Node.js, Express, PostgreSQL, Python, Docker, Git and modern AI technologies, selected according to the needs of each project rather than a fixed template.
Every project is designed with maintainability in mind. I focus on clean architecture, optimized rendering, efficient APIs, scalable databases and responsive user experiences that remain reliable as products grow.
Yes. I collaborate with startups, agencies and established businesses on projects ranging from prototypes and MVPs to production-ready software platforms.
Of course. I also provide ongoing development, feature expansion, optimization, maintenance and technical support to ensure projects continue evolving over time.
