What I'm looking for

I seek leadership roles where I can drive cloud-native transformations, mentor engineers, implement CI/CD and DevOps best practices, and deliver reliable, scalable systems aligned with business goals.

I am an experienced engineering leader with over 20 years driving innovation in scalable, cloud-native systems and microservices architectures across financial, marketplace, and government sectors.

I have led cross-functional and distributed teams to modernize legacy platforms, implement Kubernetes-based deployments, and reduce technical debt while improving operational efficiency and reliability.

My hands-on technical background includes designing fault-tolerant systems on AWS and GCP, implementing CI/CD automation, and integrating with third-party APIs such as Voucherify and Stripe.

I am passionate about mentoring engineers, aligning technology strategy with business goals, and delivering measurable value through automation, testing, and resilient architecture.
