What I Do: I help companies build AI-first products - from initial architecture to production. Think of me as your remote, hands-on CTO and Lead Engineer: I design systems, write code, manage engineering teams, collaborate with designers on UX, and ship.
My company builds large open-source platforms (ERP/CRM/HRM, Commerce, Work / Project Management), and I bring that same 0-to-1 product-building experience to every client engagement.
Over the years, I've helped hundreds of companies, from startups to large international enterprises, and have conducted business in the US, Israel, Ukraine, and Bulgaria. Worked remotely with companies worldwide: US, UK, Norway, Ukraine, India, Australia, etc.
Worked on multiple highly complex commercial projects, both in startup and enterprise environments, with small and large teams. I can work with the team or develop software independently from the ground (to production), keeping the software quality along the way extremely high!
