About Valentin

Do you have a mobile, web, or automation project?

I can help you design and deliver it from start to finish — architecture, front-end and back-end development, deployment.

  • Specializing in Flutter & Firebase, I create high-performance, gamified, and scalable mobile and web applications.
  • On the Python side, I build data pipelines, automation agents, and custom API integrations.
  • With strong autonomy, I adapt equally well to solo work and the needs of an existing team; whether it's contributing to a shared codebase, collaborating with designers, or coordinating with a CTO.

Typical Projects:
  • Flutter/Firebase Applications,
  • Flask Dashboards,
  • Scraping Agents,
Third-party API Integration,
  • SEO Optimization,
  • Figma Mockup Integration
  • English

    Fluent
