Backend & Architecture

I design microservices and API-first systems — multi-tenant SaaS, real-time messaging, and zero-downtime migrations built to scale.

/ About

Building and evolving distributed backend systems in production environments.

I build backend systems and evolve existing ones into more reliable, maintainable architectures.

I started with frontend and plugin development, then moved into JVM-based backend systems, working on areas such as gaming protocol integrations (G2S), merchant onboarding systems at Paysafe, and enterprise analytics platforms in regulated environments like Zurich Insurance.

Across these roles, my focus has been on improving system design, performance, and operational stability in production systems that cannot afford downtime or data inconsistency.

Today I work independently, helping teams design backend architectures, improve system scalability, and reduce complexity in distributed systems.
