Software engineer at Sensus Healthcare building FDA-regulated radiotherapy software and LLM agents for real businesses.
United StatesWhat I'm looking for
At Sensus Healthcare, I’m the sole developer of an iOS radiotherapy treatment-planning app, where I implemented dose-fractionation and calibration math covered by unit tests.
I designed a 21 CFR Part 11 e-signature system with a tamper-evident audit chain, and wrote Firestore security rules and TypeScript Cloud Functions for access controls and auditing.
I led Android development for the TDI device, including its USB serial protocol, syringe-pump control, and impedance safety cutoff. I also developed the SRT-100 operator console and wrote FDA, EU MDR, and NMPA documentation.
At Komba, I led development of Komba HQ, a multi-tenant gym platform, and replaced Klaviyo with an in-house marketing automation engine. I also build LLM agents and MCP servers used by real businesses, and review and test AI-generated code daily.
