Lewis Lewin

Integration-focused Full-Stack Engineer

I scale Patchworks' next-gen iPaaS currently handling 9M+ operations / day, ship features that close game changing enterprise deals, and build AI-powered scripting that lets non-devs automate and support data flows without touching code.

About

Code has been my favourite puzzle since trying to hack together dodgy Minecraft mods to make cutting wood less of a bore. That curiosity never switched off, evenings still find me making small apps to interact with random APIs . I count myself lucky to spend office hours, and after hours doing the thing that has tested my patience for all these years.

That hobby turned serious at Nottingham Trent, where a sandwich-year placement dropped me into Patchworks integration team. I was supposed to stay twelve months, instead, I kept shipping fixes and features alongside my final-year exams, proved useful, and never really left. After graduating I stayed on in Application Engineering while moonlighting as a technical account manager working with some of Patchworks' largest clients squash pain points and improve NPS scores.

Today I'm on Patchworks' Software Engineering team, I've implemented self-service enterprise SSO to unlock game-changing deals, AI-powered scripting and anything else that keeps data flowing cleanly between platforms. I'm happiest where distributed systems, clean APIs and human-centred UX meet, and I still unwind by tinkering with Rust, Go and Svelte, exploring new orchestration patterns, or starting a new project ultimately destined for my github archives.
