What I'm looking for

I’m looking to join a product team to build new products from the ground up or own and evolve existing production applications. I’m remote-ready and available for US/EU timezone overlap.

At DoctorNow, I build and maintain a Post-Acute EHR that supports clinical workflows, patient charting, and care management. I re-architected bulk PDF exports so 3,000+ PDFs could be delivered in about six minutes, and migrated the PointClickCare integration to its V2 APIs.

Previously, I led development of Ilgos, a multi-tenant eCommerce platform, including vector-based product matching with LLM re-ranking and data migration pipelines. I’ve also worked on Ideawake, an enterprise SaaS platform, and products across IoT, tax filing, logistics, and HR; I’m looking to join a product team building new products or evolving production applications.
