Full-stack developer and technical manager with 23+ years of experience building web applications, e-commerce platforms and AI-powered solutions. I specialise in rapidly delivering MVPs across diverse industries — from healthcare AI and fintech to gaming and SaaS — leveraging AI coding agents to accelerate development. Depending on complexity, MVPs reach production in 4–8 weeks. I currently run a freelance digital agency focused on custom web and desktop applications for clients across the EU.
