Client work

• Self-hosted AI assistant

  .NET 10, React+A document assistant that runs entirely inside a client network, for data that cannot leave the building.

  • Inference runs on a local Ollama and llama.cpp stack, so nothing goes to a third-party model API.
  • Embeddings for retrieval are stored in Postgres, next to the application data.

• Point-of-sale system

  .NET 10, ReactA production point-of-sale system, rebuilt on a security-first architecture.

• Customer-service platform

  C#Built in C# from the first commit through to production.

• Infrastructure and security

  Kubernetes (RKE2), Helm+The Kubernetes platform all of it ships on, plus pentesting and hardening across the same systems.

  • RKE2 with Helm, images in GHCR and Cloudflare at the edge.
  • mTLS backed by an internal PKI.
  • Pentesting, assessments and secure build practice.

Also built: a device refurbishment operations platform in C# and TypeScript; an employment portal I have worked on since 2022, rebuilt across four frontend stacks with five other developers; ERP, staff-management, field-service and marketplace systems. In all, systems for six or more client organisations at Ayaa International AB. Clients stay unnamed, by agreement.

Open source and projects
