Message

At Catapult, I designed a proprietary multi-agent platform that coordinates AI models and developer tooling across application planning, implementation, testing, and deployment. I also delivered YOOOP, a platform for women entrepreneurs now used daily by several hundred users.

Previously, I took Podyx from a single-studio MVP to a production SaaS serving over 200 paying studios worldwide. At ICICB Group, I designed and built a provably fair blockchain casino platform for Atari Chain, and at Veridos Netset I built the MVP that secured EU grant funding for a qualified electronic-signature pilot.
