About

Full-stack engineer with a passion for building products that meet people. Proven experience in building products from the ground up, leading individuals and providing direction. Did I mention that I love building products? As an individual captivated by the power of programming and its ability to change the world for the better, I'm focused on building user-oriented solutions, the right way. No problem or technology is a barrier. I've worked on traditional client-side applications, end-to-end web platforms, and mobile apps. Sometimes, I need to design mockups, and other times, jump into a production database for critical debugging - whatever needs to be done. I spend a healthy amount of my time architecting the big technical picture, and even more time putting code to IDE to make it happen. My journey began almost a decade ago, with the nostalgia of Delphi and shell scripting. I moved to explore the world of web 3 years later, with the advent of Angular.js and the forever-young Node.js used to power my Bitcoin Trader. For several further years, I added Java to my collection of tools, whilst dabbling in Haskell, C, and Python. It was time to begin focusing on solution delivery and workflow, where I acquainted myself with building CI/CD pipelines, containerisation, and orchestration, embracing the agile ideology. With these experiences, I've worked with several SMEs to build out their platforms and products, and advise on roadmap and strategic direction. In short, technology can do amazing things for people, and I'm passionate about leveraging my knowledge and experience to deliver these things. I'm always looking to expand my network, so feel free to reach out!
