About me

I always start from the user needs, and work backwards.

I excel at building end-to-end products and MVPs. I take responsibility of the application architecture, infrastructure, data model, deployment pipeline, and more. I've also supported several large companies and startups with their technology strategy and growth. Building complex user interfaces and working with designers to create pixel-perfect UIs is part of my skillset as well.

  • AI agents : I'll help you build AI agents that automate repetitive tasks, analyze data, and provide insights.
  • MVP Development : I'll work closely with you to develop a lean, functional prototype that helps validate your concept, attract investors, and gather user feedback for future iterations.
