About Gareth

Direct, Senior-Level .NET Expertise without the Hand-Holding.

With over 15 years of commercial experience, I help businesses solve complex backend problems, modernize aging infrastructure, and ship high-quality code. I don't just write software; I architect solutions that are maintainable, testable, and scalable.

What I bring to your project:

  • Legacy Modernisation: I have a proven track record of consolidating divergent codebases and reducing maintenance overhead (e.g., reducing overhead by ~50% at Intelligent Editing).
  • Cloud Architecture: Expert in transitioning infrastructure to modern stacks using Terraform, Kubernetes, and Azure/AWS.
  • Technical Mentorship: I don't just code in a silo. I mentor junior/mid-level teams, introduce TDD/functional paradigms, and establish automated workflows to accelerate release cycles.
  • Cutting Edge Tech: Active experience with AI/LLM integration, Vector DBs, and .NET Aspire.

My Core Tech Stack:

  • Languages: C# (.NET 8-10), F# (Functional Programming)

  • Cloud & DevOps: Azure, AWS, Docker, Kubernetes, Terraform
  • Architecture: Microservices, Clean Architecture, CI/CD pipelines
  • Methodology: TDD, Domain-Driven Design
Availability: I operate as a remote-first contractor. Whether you need a fractional Lead Developer to guide your team or a Senior hand to crush a backlog of complex tickets, I am ready to hit the ground running.
