Exemplar Health Care · Remote

Healthcare provider operating 60+ nursing homes with 4,000+ staff. Own multiple products end to end within a small team, working with product owners from requirements through to production support.

  • Delivered a regulatory compliance platform across 60+ sites (Django REST Framework, Angular), replacing manual spreadsheet tracking and reducing audit preparation from days to minutes.
  • Built an asset-tracking system covering 15,000+ devices (Django REST Framework, Angular), flagging equipment with out-of-date PAT testing.
  • Led the migration of codebases from individual ownership into a structured source-control organisation, and introduced the linting and documentation standards the team now works to, alongside a Confluence knowledge base and a Jira kanban workflow.

Communications & Information Specialist

Royal Navy · Portsmouth

Ran secure communications and information systems to formal security and data-handling standards. The habit of treating access control and auditability as the first design question, rather than the last, started here.

Projects

I can’t show the code I write at work, so here’s what I write for myself — the code, the Terraform, the tests, and the commit history.

Anlaby Park Community Library

Personal

wallistom/anlaby-park-community-library

Events calendar and admin area for a community-run library, so opening hours and events can be edited without touching code. One Lambda per endpoint behind API Gateway, infrastructure in Terraform, deployed by GitHub Actions authenticating through OIDC rather than stored keys, and a WCAG check that fails the build.

Built, deployed, and offered to the charity.

Document Q&A

Personal

wallistom/rag-document-qa — private for now

Question answering over uploaded documents — ingestion, pgvector search, and conversation history, with tests and CI. Retrieval filters on distance before taking the top matches, so it can return nothing and say so rather than answer from whatever was nearest.
