Loan event processing

Constraint

All loan events were being processed client-side and synchronously — loan operations blocked the UI for up to 30 seconds per action, and the business was tracking these load times daily.

What I did

Designed webhook ingestion and Azure Event Grid pipelines to route email, notifications, and downstream jobs into async flows. Moved processing off the client entirely so the UI could respond immediately.

Result

Loan open times dropped from 13 seconds to 3 seconds on the first pass. Teams kept asking to move more blocking functionality into the async pipeline — the pattern proved itself immediately.

Org-wideClaude Code + MCP adoption

AI-native developer platform

Constraint

Platform expertise lived in a legacy .NET SDK and tribal knowledge — AI coding tools couldn't reach the systems engineers actually work on, and a highly regulated lending environment rules out casual copy-paste AI use.

What I did

Built a production MCP server that gives Claude governed access to the Encompass loan origination platform, bridging modern Developer Connect APIs and legacy .NET Framework SDK calls. Rolled out Claude Code and GitHub Copilot across the engineering org with shared prompt libraries and custom MCP tooling.

Result

Code review and feature scaffolding accelerated org-wide, with AI-assisted workflows absorbing repetitive work while architecture review and production ownership stayed with engineers. The MCP server turned an AI pilot into daily infrastructure.

0 downtimelive SDK/API migration

Encompass workflow integrations

Constraint

ICE Mortgage Technologies sent an end-of-life date for their legacy .NET SDK — we had to migrate every Encompass integration off it before the deadline while keeping existing workflows running.

What I did

Rebuilt integrations around Developer Connect APIs and containerized TypeScript and C# services in Azure Container Apps with Terraform-managed deployments. Where the new APIs lacked feature parity — like the SDK's built-in popup messaging — we built custom webapp experiences to preserve the same UX.

Result

Decoupled the integration layer so workflow changes ship independently. The migration surfaced real API gaps that required workarounds, vendor negotiation, and accepting trade-offs — a live swap with no downtime on an externally imposed timeline.

Millionspaying consumer users

Consumer credit application

Constraint

TransUnion's direct-to-consumer credit monitoring dashboard serves millions of paying users — it needed continuous feature delivery (BNPL support, personalized video, UX refreshes) alongside major platform modernization.

What I did

Led teams of 10+ engineers shipping consumer-facing credit experiences across multiple redesign cycles while maintaining continuous delivery. Introduced unit testing as a core practice company-wide, personally training dozens of engineering teams on writing and maintaining their first tests.

Result

Modernized the frontend stack to React/Next.js/Vite, shipped multiple major features and redesigns, and grew engineers into senior roles. The testing culture shift outlasted any single feature.

80+services on one delivery pattern

CI/CD platform for 80+ services

Constraint

Deployments meant SSHing into servers, curling WAR files into directories, manually restarting WebLogic, and configuring each server by hand — every time, for every service.

What I did

Built the CI/CD platform as a team of three engineers — Jenkins pipelines, Kubernetes and Helm-based deployments, Terraform automation, and SonarQube quality gates. Had it running within a month, then six months of refinement as teams onboarded.

Result

Gave 80+ service teams consistent, repeatable builds and deployments. Build consistency was the biggest win — quality gates and automated scanning came later and helped, but eliminating the manual deploy ritual is what changed how teams shipped.
