Led the data integration team connecting SAP, HubSpot, and internal services. Designed and built a TypeScript microservice architecture to replace parts of an existing monolith, plus a custom gRPC code generator for the team. My role covered technical decisions, code quality, and mentoring.

04 / WHAT I BRING

Outcomes over activity.

Lines of code, hours worked, and meeting counts are poor indicators of success. I look at customer value, reliability, developer productivity, and whether the team can sustain the result.

01

Technical direction

Translate business priorities into architecture and a sequence of decisions the team can understand and execute.

02

Hands-on delivery

Move comfortably between system design, implementation, reviews, debugging, automation, and production operation.

03

A higher engineering bar

Use reviews, tooling, documentation, and technical discussion to improve the team’s overall capability—not only today’s feature.

04

Complexity made manageable

Reduce accidental complexity, clarify ownership, and create systems that remain understandable as requirements evolve.

Technology serves the business. The goal is never to use the newest framework; it is to solve the problem with technology that is reliable, understandable, and appropriate for the context.
