Senior Software Engineer

By the numbers

I’m a software engineer who has built both the platform and the product on top of it. I spent six years on how software ships, CI/CD and cloud infrastructure, at Northwestern Mutual, Veda, Cardless and GoFundMe. In 2025 I moved to building GoFundMe Pro itself, full stack, on the platform I’d helped build, so I know what each side needs from the other. Looking for Senior/Staff software engineering roles, platform or full stack. Based in Milwaukee, open to remote or relocating.

Moving GoFundMe Pro to pro.gofundme.com

A senior staff engineer brought me on as the platform’s subject-matter expert, and I led four of its product areas through the move from classy.org: Campaign Studio and the rendering engine for new campaigns, the live events platform, the Pro Services backend that call centers use on behalf of enterprise nonprofits, and the developer documentation site.

A dual-domain setup on Cloudflare, CloudFront, Route53, ECS and Lambda let us roll out behind flags and roll back fast. The move touched 27 repositories under millions of daily transactions, and the design proved out when a rollback restored service for an enterprise customer’s weekend live event, without compromising the migration timeline.

~2M
annual receipts each January, with no incidents in 2026

Annual summary receipts, redesigned

About 2 million annual summary receipts go out each January, and they came from a Lambda workload that timed out and retried. I redesigned them as an ECS Fargate task on the primary API, and won buy-in from the architecture decision makers.

The new design made possible what wasn’t before: receipts on demand, requested by donors or sent by nonprofit admins on their behalf, and year-to-date summaries. The January 2026 run had no issues or incidents.

GitHub Actions for GoFundMe Pro

I built the reusable GitHub Actions workflows and self-hosted runners that moved GoFundMe Pro off Bitbucket and AWS CodePipeline, across 8 engineering teams.

I also led moving a sharded MongoDB cluster from self-managed EC2 to MongoDB Atlas with zero customer-facing downtime, and the Kong API platform from EC2 to ECS, and mentored engineers through GoFundMe’s mentorship program.

shorter deployment times, on one CI/CD platform

Cardless’s cloud, in code

I codified all of Cardless’s production AWS infrastructure in Terraform, and wrote, and drove adoption of, the company’s first infrastructure roadmap.

I moved production Kubernetes to a new VPC at 99.9% uptime for critical services, and cut deployment times in half by consolidating DevOps tools into one CI/CD platform.

CI/CD for 3,000+ engineers

I designed and maintained the shared GitLab CI/CD platform that 3,000+ engineers shipped through, standardizing security, testing and deployment.

I was an early contributor to the company’s adoption of AWS CDK, and built the Python and Redshift data collection leadership used to measure DORA metrics.

Off the keyboard I run marathons and backpack: in August 2025 I walked the Arctic Circle Trail, 167 km across Greenland. My long trail at home is the Ice Age Trail, and I'm a dog dad to two puppers.

  • Technical lead for four product areas in moving GoFundMe Pro from classy.org to pro.gofundme.com (Nov 2025 – Mar 2026), brought on by a senior staff engineer as the platform’s subject-matter expert: Campaign Studio and the rendering engine for new campaigns, the live events platform, the Pro Services backend that call centers use on behalf of enterprise nonprofits, and the developer documentation site. The move touched 27 repositories, under millions of daily transactions, and used a dual-domain setup on Cloudflare, CloudFront, Route53, ECS and Lambda for flag-driven rollout and fast rollback, which proved out when a rollback restored service for an enterprise customer’s weekend live event without compromising the migration timeline.

The January 2026 run had no issues or incidents.
  • Cut CI pipeline time from 17 to 10 minutes (about 41%) through dependency upgrades, a pnpm migration and selective test execution, and added ephemeral preview environments for AI-agent and developer iteration.
  • Built reporting, data and onboarding features in the admin nonprofit administrators use to run their fundraising.
  • On Post-Donate, worked on everything a donor sees after giving: the thank-you page, transactional emails, and the start of share attribution.
  • Used Claude across the development lifecycle, from PRDs and scoping to QA.
