Hey, I'm John.
Senior Full Stack Engineer based in the UK, with 8+ years of experience building high-performance, scalable web applications.
I hold a Bachelor's and MSc in Computer Science and currently work at Goodfit.io, where I build with AWS, TypeScript, and React.
Outside of work, I explore Go, Python, Rust, and Kotlin. I'm also passionate about serverless architecture with AWS Lambda, S3, and SQS.
When I'm not coding I really enjoy reading, playing music, hiking, or traveling.
