About

I help companies improve business-critical applications and the processes around them. My experience spans legacy application modernization, backend and full-stack development, APIs and integrations, cloud systems, data platforms, and technical leadership.

I've worked on everything from modernizing legacy applications to building cloud-based solutions and improving complex data and engineering processes. Most recently, I served as a Technical Lead at S&P Global, leading the development of enterprise software and data solutions on AWS. I incorporate AI-assisted development into my engineering workflow to support analysis, implementation, documentation, and spec-driven development while maintaining strong engineering standards and oversight.

Why Work With Me

Nearly 20 Years of Experience

Hands-on software engineering across legacy and modern systems in a wide range of industries.

Technical + Product Thinking

I consider both how software is built and how it should work for its users and the business.

Hands-On Through Implementation

I stay involved beyond recommendations and help put improvements into practice with your team.

My Approach

I focus on practical, maintainable solutions that solve real business problems. I take the time to understand your goals, constraints, and existing systems, then design and implement improvements that deliver measurable value.

I believe in iterative progress over big-bang rewrites, clear communication, and building solutions your team can successfully maintain and evolve.
