About Me

I'm Lucas, a software engineer and tech lead with more than 20 years of hands-on experience building web applications. My background is strongest on the back end (Ruby on Rails, TypeScript, Node.js, PostgreSQL, AWS) but I know my way around modern front-end frameworks like React, Svelte and Astro, and I've shipped production code across the full stack for most of my career.

I started out as a freelance developer in Germany while studying computer science at the University of Bremen, building client projects in Rails and .NET before joining Wimdu in Berlin, where I led a team of seven and helped increase conversion rates by 12% in six months. A move to XING followed, then to London — first at Elsevier's Mendeley, where I built internal tooling adopted across all web development teams and won a company award for running a monthly hack day that gave everyone in the company time learn something new through projects of their own choosing. Then at Resolver, where I managed a team of ten developers, owned and maintained the B2C side of the service while delivering the infrastructure for an expansion into South Africa.

Since then I've worked as a senior engineer and tech lead at Board Intelligence, HomeHero and Indeed Flex, focusing on API design, cloud infrastructure and improving development processes. Highlights include a 400x speed-up of a critical data export, taking ownership of core micro-services on AWS Lambda, and leading feature builds that reduced operational workload and fostered cross-team knowledge sharing.

In 2022, when COVID-19 travel restrictions were lifted, I took the opportunity to travel Southeast Asia, which is something I'd been planning for years. I spent close to two years exploring the region, and along the way co-founded TEFL GIGS, connecting English teachers with schools in Thailand, and continued taking on contract work remotely: leading a crypto wallet project from prototype to production at Mara, driving the rewrite of Goosechase's back-end application, and delivering a nationwide survey platform for dxw.

Today I run GEEK4GOOD, partnering with startups and established organisations to architect, build and ship software. I have a keen interest in software architecture and cloud infrastructure, and I make a point of keeping up with developments in the space. But I never lose sight of what matters most: solving real problems with well-built, reliable software.
