What I'm looking for

I'm seeking a senior engineering role where I can design scalable systems, lead technical teams, apply AI to accelerate delivery, and drive measurable business impact.

I'm a seasoned Software Architect and Java developer with over 20 years of hands-on experience building low-latency, high-load platforms for finance and enterprise clients.

I specialize in system design, performance optimization and automation, leveraging refactoring, scripting and generative AI to accelerate delivery while hardening production code.

I've led Agile transformations, hired and mentored cross-functional teams, and taken ownership of complex pricing and risk engines—driving measurable improvements such as 20% response-time reduction and 80% reduction in bank losses.

Technically fluent in Java (JDK 8–17), Groovy, Spring, Kafka, Azure and container platforms, I focus on time-to-market, reliability, and scalable architectures that serve global, active-active deployments.
