Hello, I'm DanielI'm a Full Stack Software Engineer.
About Me
I’m Daniel Barrow, a Full Stack Software Engineer based in Worcester. I am passionate about software engineering, but not just the coding element of it, I love working with people to think through a problem and find the best way to solve it and at the same time offer the best value to an end user. I take real pride in building solutions that are high quality, secure, scalable, and accessible, and there’s nothing more satisfying than seeing them work seamlessly for those who use them.
I hold a Master’s in Computing from Cardiff University (Distinction) and have 5 years of hands-on experience as a Software Engineering Consultant. My work spans sectors from government to video games, across diverse systems, technologies, languages, and frameworks which is very much reflected in my stack below.
