I’m Kai Russo, a fractional Senior Full-Stack Engineer who helps small teams ship technically difficult products, especially in regulated healthcare and multi-tenant SaaS environments. I bring 10 years of end-to-end ownership across architecture, implementation, integrations, and production delivery—often turning complex reporting and governed data requirements into reliable systems that stakeholders can trust. I’m currently focused on data infrastructure, with capacity for additional product work. I’ve led multi-tenant platforms with strong tenant isolation, built production LLM features, and delivered integrations like Google Calendar and Microsoft Graph with per-tenant OAuth and recurrence handling. I also have deep experience rewriting and operating clinical scheduling systems, where I improved quality execution and dramatically reduced QA backlog while coordinating with cross-functional teams.…I’m Kai Russo, a fractional Senior Full-Stack Engineer who helps small teams ship technically difficult products, especially in regulated healthcare and multi-tenant SaaS environments.
