I am a full stack software engineer with extensive experience developing software in Typescript, PHP, C++ and C#. I can independently create and maintain full-stack, reactive, web-enabled applications modern tools and methodologies. I have experience developing for embedded systems, corporate middleware, and web applications. My preferred development stack today is Linux, Docker, Typescript, React and Next JS but I can adapt quickly to new platforms. I develop software using Visual Studio code (vscode). My personal history and skill-set enables me to create high quality software, both autonomously and as an effective member of an agile software development team. I have experience working in both scrum and kanban workflows. I can facilitate all elements required to deliver content on the web, managing servers and software utilising a variety of standard processes and tools from custom Linux scripting, to proven Infrastructure-as-Code management tools. I also have recent experience working alongside a dev-ops team to deploy software to AWS and resolve deployment related issues. As well as being able to create software I have noteworthy skills in diagnostics and software testing and I can assist with diagnosing and resolving complex software related issues and bugs.

I consider software development to be more than a job. It is my vocation, my hobby and my passion. I have spent several years fully engaged in independent discovery, research and development using bleeding edge open-source software web technology, engaging directly with platform and package developers to identify, discover and resolve technical problems without any corporate support. As such, I have been able to discover for myself the best technical solutions and industry leading software, free from commercial constraints and agendas. Aside from software development I also have enduring interests in digital currency investment, general investing, accounting, contract, and trust law. To diversify my skills and train both sides of my brain I have also been learning music (theory, guitar, piano, bass guitar and vocals) which has involved amateur public performances and I consider myself a confident and capable performer and public speaker. Music offers my family and friends engagement and enjoyment and I am now passing on my music skills to my to two young children with whom I spend most of my spare time.

Technical Activities: Full stack software engineer employed to create software in Next JS and Nest JS, developing locally with Docker and deploying to AWS using Terrafom scripts. I significantly increased unit and e2e Jest test coverage on both front end and back end code and assisted junior devs in advancing their understanding of Jest. I fixed long standing issues with memory leaks and was able to speed up e2e tests by freeing up system resources during long tests, I implemented observability across backend software using Opentelemetry pipeline to diagnose and resolve long standing issues with Queue processing. I also helped to restructure a poorly implemented microservice monorepo architecture to sanitise module and package management, and simplify further development.
