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.

Dec 2023 to present

Next.js 14 development and authentication strategies, Syntapse Ltd

Technical Activities: I took voluntary redundancy from my last employed role to create a pnpm monorepo to understand monorepo best practices and to exercise and demonstrate Next.JS 14 features. I am hosting https://nextdemo.syntapse.co.uk to showcase the new Next app router architecture along with latest APIs for React and Redux Toolkit. I have included a web socket chat feature to demonstrate integration with a Nest.JS web socket gateway (sharing types for client and server type conformance), an e-commerce cart payment flow implemented using only Redux Toolkit (no third party packages) and a variety of features including React Server Components and actions. I am also hosting https://nextauth.syntapse.co.uk to demonstrate how to extend NextAuth.JS to create a secure role based Oauth enabled authentication system with email verified registrations and 2FA logins. All sites and servers are hosted with docker, configured to run production and development servers simultaneously using a single code base in a very well structured pnpm mono repo.

Full stack software engineer, Spotlight Sports Group

Technologies: Docker, microservices, monorepos (npm and Nx), Typescript, TyepORM, Next JS, AWS, React, Nest JS, Bull Queue, Opentelemetry, Grafana, Prometheus, Jaeger, Bitbucket, Jenkins

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.
