• Built an internal UI for debugging and managing configuration of 500,000+ Twilio accounts (React), with support for management of per-account geographic permissions.

• Enabled automated testing requiring real phone numbers by guiding design of and scaling a system for leasing phone numbers to automated test suites (Java, MySQL). Scaled proof-of-concept system to be capable of managing pools of 1200+ numbers, leasing 20-30 per minute.

◦ Improved reliability of calling infrastructure by extracting critical business logic into isolated deployables, improving both performance and uptime.

◦ Reduced complexity of making API calls to HubSpot’s third-party calling provider (Twilio) by developing a reusable and flexible client library (Java) for loading auth credentials, making API requests, and logging critical information and metrics.

• Enabled customer management of devices deployed in hospitals and other sensitive locations by building a CRM- like web application (Java, Go, React) capable of handling thousands of active devices per tenant.

• Enabled automation of common support workflows (uploading log files, running on-device commands) triggered

by telemetry uploaded from an agent (Go) running on managed devices.

• Reduced time and cost for customers to service devices by implementing secure remote access tunneling (Go).

• Lead engineer (one of three) for maiData. Worked with the other engineers and leadership break down problems and scope features during development.

• Set up and maintained maiData’s runtime infrastructure and development tooling (Kubernetes, GitHub Actions)

• Improved customer confidence in making complex changes by building out isolated test environments. Brought the project from inception to general availability over 10 months.

• Allowed customers to use production data in their sandbox environments by building a distributed sync framework (Java), where HubSpot teams managed the logic used to copy the data they owned between accounts.

• Collaborated with 5+ teams to implement the sandbox data-sync framework for their owned data types.
