I build reliable systems and optimize infrastructure that delivers real business value. Currently exploring new opportunities where I can make meaningful impact. ## Recent Impact I take complex technical challenges and solve them pragmatically. In my last role, I led platform engineering initiatives at rapidly-growing community management scale-up (200 employees, 600+ communities, with largest communities serving 1M+ users each): - Architected and optimized data exports, reducing processing time by 98% for communities with 1M+ users - Rebuilt CI/CD infrastructure, cutting build times in half while reducing costs - Streamlined developer environment setup from days to hours through practical tooling - Led critical infrastructure cost optimization initiatives saving €160k annually But the numbers only tell part of the story. What really drives me is seeing the impact of my work - whether that's helping a client successfully export their data, making deployments more reliable, or helping colleagues be more productive. ## How I Work - Finding the simplest solution that works - Making sure we're solving actual problems - Building systems that are easy to understand and maintain - Documenting the "why" behind technical decisions - Making observability a priority - I build dashboards that help teams understand system behaviour - Using data to guide optimization decisions rather than gut feelings I enjoy startup and scale-up environments where I can work with small, capable teams. I value autonomy, trust, and the ability to directly see the impact of my work - whether through metrics, user feedback, or team productivity. My approach focuses on gradual, measured improvements rather than risky rewrites. ## What I'm Looking For - Solve interesting technical challenges that matter - Work with teams that value pragmatic solutions - Continue growing and learning new technologies - Have direct impact on business success I prefer fully remote work with occasional office visits for collaboration and team building. Strong background in Ruby/Rails with experience in complex system optimization, but always interested in learning new tools when they add real value.

I'm a senior software developer with a wide amount of experience! I was first hired in software when I was 14 years old, given me almost 25 years of experience in software and engineering. I can typically be found at the backend of the software stack, but I have some experience with frontend concerns as well. If you have high performance or data science heavy API development needs I'm certainly your guy! - I still can't decide whether I like Django or Rails more! - I really, really know SQL well! I'm even the core maintainer of a ORM extension to Rails called ActiveRecord::HierarchicalQuery and I've had many minor OSS contributions over the years including to Rails, ZeroMQ, and Nim! - I care deeply about giving back civically and have met with various government leaders and journalists to make sure our society is safe from cyberattack, even though cybersecurity is only a secondary skill of mine. - Hire me for a contract and you soon may find me as a full-time employee! I'm looking for something long term and I'm very friendly :)

I'm easily trigged by common phrases in the programming world, like "What is happening?" I've been working professionally with ReactJs, React-Native, Rails and GraphQl for years. I always follow SOLID design principles whenever I am working with Javascript or Ruby/Python. Every single day I make a lot of mistakes, which makes me a lot more comfortable on programming as well. Like Randy Nelson said: "The core skill of innovators is error recovery, not failure avoidance".
