Welcome!

This is where I share stuff from some of my various interests and hobbies.

Brief Introduction

tldr; I enjoy programming and working in vibrant, energetic teams.

I started in computer systems management as a systems operator. I enjoyed learning and started writing scripts to automate many of the processes routinely performed in my day to day duties. This was the beginning of my interest in programming. I studied C using the eponymous classic K&R book and many online resources. Since those early stages, I have continued to research areas that draw my attention and have picked up other languages such as Python, Java and most recently Go and Rust.

In the last few years I have been enjoying working in projects primarily in distributed, cloud based systems and my diverse experiences across many business sectors have helped shape my solutions. Another key lesson has been the value of the team around me. I enjoy learning new approaches and helping others where I can. I have learned to take criticism well since I recognise this is the best way for me to improve the quality of my work.

Technologies I have experience with

  • HTTP/2
  • TLS / SSL
  • Symmetric and Asymmetric key based encryption
  • Docker
  • Istio / Envoy
  • Marathon/Mesos
  • Kubernetes
  • Google Cloud / AWS
  • Prometheus / Opencensus / Sentry
  • Kafka / PubSub / RabbitMQ
  • ElasticSearch
  • Version control (Github / Gitlab / Bitbucket)
  • PostgreSQL
  • Various web frameworks (Actix, Warp, Iron, Chi, Go-Kit, gRPC etc)
  • PivotalTracker / YouTrack / Jira
