Fighting Spam at Scale: A Journey

Join me on a decade-long journey of fighting spam on a dating platform. From wrestling with databases to streaming at scale with Kafka, we built a rule-based antispam system with AI on the sidelines. Meet Sheriff, Tracer, and friends – our heroes running spam through the meat grinder.

Delete Your Technical Debt: How Toyota’s ‘Stop the Line’ Philosophy Creates Self-Healing Code

Working at Toyota Group, I discovered their “stop the line” principle doesn’t just build better cars – it eliminates technical debt before it exists. Live demos show how Japanese manufacturing patterns create code that literally heals itself, with real examples from industrial IoT systems.

Leveling Up in Job Interviews

You’ve probably applied for a developer job you really wanted but didn’t get. More often than not, the interview is what decides the hire. This talk equips you for challenging interviews and takes you to the other side of the table. We’ll look at what technical skills, character traits, values, and cultural aspects interviewers pay attention to — and what questions they ask to assess them. We’ll also cover the tools interviewers use. All of this is backed by entertaining anecdotes from real interview experiences. The talk is aimed at leaders who want to sharpen their interviewing skills and developers who want to stand out in their next interview.

GPUs beyond deep learning and gaming: Solving hard problems with back propagation

Backpropagation isn’t just for AI. See how it can solve hard problems by working backwards._x000D_ As an example, we’ll draw any given picture – but with stamps. And instead of writing a complex algorithm, we’ll implement the easy part (rendering a stamp) and let the GPU find the optimal placement for us.

Safely through the dependency minefield using OWASP Dependency Track

Security in software development is becoming more and more of a central issue. But with increasing complexity of our software and attacks on it, it is getting more important to keep an eye on all dependencies. The OWASP Dependency-Track tool offers a simple and effective solution for exactly this.

Strangler Fig in production – An essay about friction-free application migration

When your frontend application becomes unmaintainable, a rewrite might be the only viable option to get rid of slow releases, technical debt, and inconsistent patterns. Staffbase executes this by implementing a progressive replacement strategy, leveraging the Strangler Fig Pattern and a modern monorepo tech stack (TypeScript, Turborepo, Tailwind CSS, Tanstack Router). The result is faster development, safer rollouts, built-in accessibility, and clear ownership across development teams.

Portal Hell: Why building platforms always feels harder than it should

Portal or platform development often starts simple and ends in chaos. In this talk, we uncover why complexity sneaks in, from scattered stacks to unclear design choices, and what principles help keep control before tech debt takes over.

I launched 6 startups in 8 months (and 5 of them failed)

A story about founding multiple startups, securing funding, and building complex products. One exit, funding disclosed. The key lesson: Success comes from having the right people around you to tackle tough problems. It’s not just about shipping more, but shipping faster. Motivation is finite, especially with a team involved.
