What I'm looking for
I am a seasoned senior software engineer and project manager with over 20 years delivering large-scale software, IT infrastructure, and big data systems across global enterprises. I combine deep technical expertise with proven leadership to drive projects to on-time, under-budget delivery.

I have a strong track record in vendor and budget management, stakeholder communication, and maintaining high delivery standards.
Technically, I am proficient in Java, Python, C/C++, SQL, and a wide range of tools including AWS, Terraform, Jenkins, Docker, Airflow, Spark, and Presto. I have driven cost reductions in procurement, implemented CI/CD and DevOps practices, and mentored engineering teams to improve practices and knowledge sharing.
I value pragmatic process improvement, clear technical documentation, and collaborative team cultures where cross-functional teams can deliver resilient systems at scale. I am motivated to join organizations that need experienced technical leadership to modernize systems and accelerate delivery.
