professional experience
Heales MedicalSoftware Engineer
Hitchin, UK · 2022 – Present
  • Led frontend development of a Svelte KPI dashboard on Elixir/Phoenix APIs, turning operational and reporting requirements into a tool used across case data, and tracing reporting discrepancies back to the rules that caused them.
  • Worked directly with a university client to design and ship an occupational-health API integration in Phoenix, covering request validation, JSON/CSV handling, AES/PGP encryption and SFTP delivery tested end to end against their transfer setup.
  • Diagnosed production failures across devices and networks on a Phoenix/WebRTC conferencing application, resolving ICE/TURN connectivity, signalling and device-specific issues from service logs and browser diagnostics.
  • Develop and maintain REST APIs and database integrations for occupational-health applications, translating operational requirements into backend services and the interfaces that sit on top of them.
  • Drove migration of legacy Java functionality to Elixir/Svelte and kept it shipping, with GitLab CI/CD and deployment and maintenance of Linux container services.
  • Built and deployed an adaptive HLS video platform delivering multiple bitrates so staff on constrained or unreliable connections could still stream reliably.
