About Mihai

9+ years experience as a software developer, with Bachelor and Masters degree in Neural Networks at University of Polytechnic Bucharest.

I have 8 years experience in enterprise with both waterfall and agile methodologies.

I have 4 years experience as a freelancer, building two major projects until now:
- created an end to end system for publishing companies that is doing 200.000+ annual reports, having ownership on the backend, frontend, database and automation workflows.
- built an MVP for an automotive company that is transitioning to startup and is currently onboarding 1000 users, having ownership on the backend, frontend, database and automation workflows.

Actively, I am implementing custom AI agents for small business to help them improve their business performances with up to 80%.
