> about_me
I'm a full-stack developer, currently building C# / .NET and SQL Server features at PeopleCert. That's my focus today, and it sits on top of two decades of hands-on work across networks, telecommunications, wireless and IoT.
I ship full-stack applications with C# / .NET, TypeScript, React and Next.js, backed by SQL Server and PostgreSQL and containerised with Docker. AI-assisted development is part of how I work every day: I script and automate with it, lean on a planning- and research-first method, and enjoy helping other developers use it well. I'm methodical and well organised, work equally well solo or in a team, and bring a positive attitude.
Underneath sits networking and telecommunications: MikroTik infrastructure, complex VLANs, VPN tunnels, BGP/OSPF and network automation, plus years of field and RF work, from microwave P2P links and LoRa/wMBUS metering to WiFi, antenna alignment and fiber / PON.
Security runs through all of it, but as a mindset and a skill rather than a job title: I design, test and harden what I build, from the application layer down to routers, wireless links and devices. It's an area I genuinely love and keep pushing to grow in.
If it runs on electrons, I've probably worked on it.
