What I'm looking for

I seek senior engineering leadership roles where I can drive cloud-native, streaming, and functional-programming solutions, mentor teams, and deliver scalable financial-services platforms.

I am a Technical Project Manager and Partner Solutions Architect with a Master of Science in Computer Science and a career building and leading globally distributed development teams to deliver high-quality software.

I have led large-scale, bank-wide platform projects using functional programming (Scala, FS2, Cats Effect), streaming architectures (Kafka, Akka Streams), and cloud solutions (AWS, Azure) to achieve scalability, performance, and vendor independence.

As a hands-on engineering leader and mentor, I modernized team skillsets, introduced CI/CD best practices, and delivered measurable improvements — including a cloud archiving platform adopted by 300+ applications and a 22-month streak of production stability.

I thrive in agile, continuous delivery environments, make data-driven decisions, evangelize TDD/BDD and functional paradigms, and seek opportunities to learn and contribute innovatively to teams and the broader community.
