What I'm looking for

I seek a hands-on leadership role building scalable, cloud-native SaaS platforms where I can mentor engineers, drive product outcomes, and deliver measurable cost and reliability improvements.

I am a hands-on Engineering Manager and Senior Software Engineer with deep experience in full-stack development, cloud architecture, and people leadership. I deliver scalable, cost-saving solutions and build resilient, event-driven systems.

At GoStudent I led a cross-functional team of seven engineers, achieved 0% churn over two years, automated flows that saved €500k/year, and improved communication costs and product engagement.

I design and implement cloud-native architectures using Go, TypeScript, React, AWS, Docker, Kubernetes, and observability tooling, and I ship features that improve uptime and customer trust.

I am passionate about mentoring engineers, driving product-roadmap execution, and building multi-tenant SaaS platforms that create measurable business value.
