What I'm looking for

I seek roles where I can lead architecture and engineering efforts—building scalable microservices, leveraging cloud and streaming platforms, driving automation, and mentoring teams in an agile, outcomes-focused organization.

I am a Senior Java Developer and IT leader with 18+ years delivering scalable, high-availability systems across financial services, education, and enterprise environments.

I specialize in Java, Spring Boot, microservices, Kafka, and cloud architectures, combining hands-on technical expertise with strategic vision to align technology with business goals.

My achievements include designing microservices handling millions of transactions daily with 99.95% uptime, architecting Kafka pipelines processing 1M+ daily events, optimizing cloud infrastructures (AWS, GCP) to improve performance by 35%, and automating processes with Python to reduce manual work.

I led multidisciplinary IT teams, managed infrastructure and projects using ITIL and COBIT, modernized legacy systems, reduced costs through outsourcing negotiations, and delivered measurable performance and reliability improvements that supported business objectives.
