Profile

Building reliable connections between business systems.

Consultant and product engineer with 6+ years of experience building and integrating enterprise applications end-to-end. I specialize in connecting business systems — ERP, quality management, and document platforms — into reliable, automated data flows, and I own integrations from planning through implementation and operations.

I work closely with sales, quality, and cross-functional teams to translate business needs into technical solutions, and I am looking to grow that scope into leading integration strategy and a team.
