How I work

Pragmatic, thorough and product-minded.

Good systems are not just technically sound, they help people make progress.

Leadership as leverage

Technical leadership works best close to the system. I stay hands-on with architecture and code so the decisions stay grounded in reality.

Quality that lasts

I favour robust, well-understood solutions that remain maintainable as products and teams grow.

Clear feedback

Open communication, shared context and direct feedback are essential to effective engineering teams.

Context before code

I start with the problem and its users, then make technical decisions that serve the wider product.

Let's build something reliable.

If you are hiring for a senior platform and reliability engineer with a backend and cloud-security background, I'd be glad to hear from you.
