About me

Technology with a business purpose.

Delivering value with appropriate and scalable solutions is how I choose to contribute to a company’s success.

I specialise in high-traffic commercial websites and backend services, combining hands-on product engineering with software architecture, functional and technical design, team leadership, and business-oriented solutions.

I thrive on turning complex requirements into maintainable systems, helping teams make technical decisions, and creating the conditions for people and products to improve continuously.

Architecture

Scalable systems designed around real business needs.

Collaboration

Defining and shaping solutions. Alignment, mentoring.

Delivery

Strong focus on robust, reliable deployments and observability.

Technology stack

A technology stack built for modern products.

From user interfaces to distributed systems and cloud delivery, I choose tools—including .NET, Node.js, Kubernetes, Docker, AWS resources— according to the problem, not the trend.
