I develop top-quality mobile, web, and desktop apps, often with AI features. I also work as a UX consultant and IT project manager. I always strive for excellent software — delivering average work is not an option for me. I put 100% effort into everything I do and always walk the extra mile. The result is apps that users love to use and that meet business goals. What I do: • mobile and multi-platform apps in Flutter (iOS and Android, web and desktop) • AI integrations, I enjoy solving advanced AI problems (e.g. by stacking AI models, distillation, fine-tuning, MoE, RAG, etc.) • complex software systems consisting of multiple connected applications • UX consultancy, UX audits (just UX, I am not a designer) • I lead a team of very talented software developers focused on Flutter, AI, and complex systems I am a member of the prestigious Toptal network and part of Upwork’s 🏆Expert-Vetted Talent🏆 program, which unites the top 1% of freelancers on Upwork (badge visible to enterprise clients only). Hiring top talent greatly enhances your business's chances of success! What I bring to the table: ✓ 13 years of combined development, consulting & tech leadership experience ✓ creative solutions, ideas & improvements ✓ an agile process that lets you stay on top of progress and quality ✓ highest engineering & algorithmic competence ✓ strong work ethics & accountability ✓ focus on detail, almost to a degree of perfectionism ✓ truly fluent in English with strong communication skills ✓ ability to speak simply and clearly about engineering and align it with business goals ✓ always up-to-date with cutting-edge tech ✓ master's degree in software engineering from a top EU university, where I now lecture on Flutter ✓ 12 years of AI and ML development experience with excellent knowledge of state-of-the-art AI models, development techniques, and APIs Have a question? Need tech consulting or want to build a mobile app? Drop me a line!
