Hello! I'm Davey πŸ‘‹

"If it ain't broken... maybe we can make it better. If it's broken, I can probably fix it."

Computer Science graduate and infrastructure engineer with a decade of experience across networking, embedded hardware, and systems integration β€” from circuit to cloud. I've built and maintained live off-grid infrastructure, engineered networking systems for CAA-regulated drone swarm operations, and written the software to tie it all together.

Currently studying for my Cisco CCNA, formalising knowledge I already apply in practice. I'm undertaking the NetworkChuck Premium Summer of CCNA β€” a structured, intensive programme with a clear pathway to certification.

Alongside that, I'm enthusiastic about AI-assisted development β€” Claude and agentic workflows are a genuine part of how I work now, not a curiosity. I've started working directly through the Anthropic course catalogue to stay current, completing Claude Code in Action and Intro to Agent Skills, with more in progress.

I regularly take courses on Boot.dev alongside everything else β€” less focused on the backend route these days, more on developing tools and skills for a professional workflow. CI/CD, Docker, DSA, Linux, and Memory Management in C are among the 11 completed so far. Check my profile.

πŸ† Cool Projects

  • Engineered 4G/RF/fibre network infrastructure for the UK's first CAA-approved 500-drone light show
  • Designed and maintain live off-grid power and network systems across multiple remote sites
  • Built a fulfilment system on the fly processing 5,000+ orders at >95% success rate
  • Design & print 3D solutions for real-world infrastructure problems

🌱 Current Focus

  • Cisco CCNA β€” routing, switching, network security, LAN/WAN
  • Linux systems administration and infrastructure tooling
  • Networking tools: Wireshark, nmap, Packet Tracer
  • Using Git everywhere, all the time, always
  • Vim motions β€” why did I not do this years ago?
