What I'm looking for

I seek a role where I can lead cross-functional teams, deliver data-driven products, grow engineering capability, and balance technical and business priorities.

I am a Technical Project Manager with over six years in IT and a strong engineering background in backend development, primarily Ruby on Rails. I operate at the intersection of business and technology, translating strategic goals into structured execution and measurable outcomes.

I lead cross-cultural engineering teams, combine delivery leadership with hands-on engineering support, and have delivered data-driven internal tools and end-to-end Ruby on Rails projects. Notable achievements include streamlining an annual update process from six months to one month and contributing to large-scale banking system migrations.

I focus on delivery, accountability, and building environments where people grow and take ownership, facilitating Agile ceremonies and coordinating stakeholders across multiple time zones to produce scalable, high-quality products.
