About

What DigiVici is

After gaining experience as a software engineer, I became increasingly interested in more than just building software: identifying real problems, innovative opportunities, validating new ideas and turning the strongest ones into useful digital products.

Through DigiVici, I help startups and small companies turn ideas and challenges into apps, websites and other digital solutions. I also build and validate my own products and experiments in AI, software and creative technology.

My focus is on understanding what people actually need, deciding what is worth building, experimenting quickly and improving ideas through real feedback. I use agentic engineering and modern AI tools to accelerate development, while keeping usability, reliability and technical quality at the core.
