ABOUT ME
A senior software engineer with 10 years of experience
A senior software engineer with 10 years of experience
I've a wealth of experience working as a software engineer within companies big and small. I'm primarily a full-stack engineer, working with HTML and modern JS frameworks on the frontend, and Javascript/Python backends and APIs. I've got experience working with production systems handling 1000s of requests a minute, distributed microservice architectures, python monoliths and more. I've also got a lot of experience with games engines, having built mobile games and VR applications, as well as releasing several react native mobile apps, working as a data scientist and with AI.
But there's more to programming than just that, I've got experience with what programming looks like in the real world, whether that's working effectively with others, Agile methodologies, communicating to stakeholders, design, and more. I've worked in a range of companies doing things in all sorts of different ways and I can teach you what works, what doesn't, what a real world job is like, and more.

Olly was a brilliant mentor. He explains concepts really well and is a great communicator
Scott Campbell

Olly is absolutely fantastic! I inherited an extremely complex codebase, with some really funny design decisions, and Olly was able to walk me through it, learning quickly on the fly, and mentoring me as I added a new component to the code. Great bedside manner, great at translating difficult concepts into English.

Spoke to Olly regarding career and industry guidance. He was extremely helpful, clear and brought tons of experience and insight, and was a pleasure to speak to. My path forward is now much clearer. Thanks Olly!
