The call-center donation app, modernized

The job
Pro Services is how enterprise nonprofits and their call centers take donations over the phone and handle back-end tasks. Two company initiatives, one front-end monolith and a new design system, needed it migrated off Create React App and its custom components.
What I did
I ported its 26 screens and their logic to Next.js in the monolith and onto the design system, rewrote its unit and Playwright tests, and used the existing end-to-end tests for regression.
How it went
It was ready to release in October 2026, behind feature flags, with a cookie to switch between the old and new apps.

Migrating GoFundMe Pro to pro.gofundme.com

The job
Migrate GoFundMe Pro from classy.org to pro.gofundme.com, across 27 repositories, under millions of daily transactions.
What I did
A senior staff engineer brought me on as the platform’s subject-matter expert. I led the migration effort of 4 product surfaces to safely roll out dual-domain support behind feature flags.
How it went
The release was successful. We did have to use the feature flag gate for our live events platform, where it restored service for an enterprise customer’s weekend event.

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

Annual summary receipts, redesigned

The job
About 2 million annual summary receipts go out each January, and they came from a Lambda workload that timed out and retried.
What I did
I redesigned them as an ECS Fargate task on the primary API, and won buy-in from the architecture decision makers.
How it went
The January 2026 run had no issues or incidents. Donors can now request receipts on demand, nonprofit admins can send them on donors’ behalf, and there are year-to-date summaries.

customer-facing downtime migrating our donation pages’ database to Atlas

The database behind donation pages

I led migrating the sharded MongoDB cluster behind our donation campaign pages and email templates from self-managed EC2 to MongoDB Atlas, with zero customer-facing downtime.

I also led migrating the Kong API platform from EC2 to ECS.

engineering teams migrated onto shared GitHub Actions

GitHub Actions for GoFundMe Pro

I set up the central GitHub Actions repository, two workflow templates built from shared jobs and steps, and the self-hosted runners that migrated GoFundMe Pro off Bitbucket and AWS CodePipeline, used by about 40 repositories across 8 engineering teams.

It gave each repository its own settings for deployment and manual gates.

Cardless’s deployments, cut in half

I cut deployment times in half by consolidating DevOps tools into one CI/CD platform, and wrote, and drove adoption of, the company’s first infrastructure roadmap.

I codified all of Cardless’s production AWS infrastructure in Terraform, and migrated production Kubernetes to a new VPC at 99.9% uptime for critical services.

Reusable infrastructure as code

I built 12 reusable AWS CDK constructs and Terraform modules for cloud-native applications in Python and TypeScript.

I also led the company-wide migration from GitHub to GitLab, with shared CI/CD pipelines on an autoscaling EC2 runner platform, and brought Datadog observability to our AWS infrastructure and workloads.

CI/CD for 3,000+ engineers

I developed and maintained the reusable GitLab CI templates 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.

Tripp Horbinski

Senior Software Engineer · Milwaukee, Wisconsin (open to remote, Boulder or San Francisco)

Senior software engineer with 8 years of experience across platform and product. Six years in cloud and DevOps, owning how software ships from commit to production, then nearly two building GoFundMe Pro full stack, on that platform, in TypeScript, Next.js and AWS. On call at every company. AWS Golden Jacket recipient.

Experience

GoFundMe, Senior Software EngineerApr 2023 – Oct 2026 · Remote

Full stack, GoFundMe ProJan 2025 – Oct 2026

  • Technical lead for four product areas in migrating 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, GoFundMe Pro Services, which call centers use on behalf of enterprise nonprofits, and the developer documentation site. The migration 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.
  • Led the redesign of the annual summary receipts, about 2 million generated each January: migrated them from a Lambda workload that timed out and retried into an ECS Fargate task on the primary API, won buy-in from the architecture decision makers, and added what wasn’t possible 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.
  • 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.
  • As the only engineer on the project (Jul – Oct 2026), ported Pro Services, the 8-year-old application enterprise nonprofits and their call centers use to take donations by phone, from Create React App to Next.js in the front-end monolith and onto the new design system: 26 screens, with rewritten unit and Playwright tests, ready to release behind feature flags and a cookie toggle.
  • 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.

Cloud and platformApr 2023 – Dec 2024

  • Set up the central GitHub Actions repository, two workflow templates built from shared jobs and steps, and the self-hosted runners that migrated GoFundMe Pro off Bitbucket and AWS CodePipeline, used by about 40 repositories across 8 engineering teams.
  • On call for the July 2024 AWS Kinesis outage in us-east-1: CloudWatch Logs failures kept new ECS tasks from starting during a scaling event and left only the old, overloaded tasks logging. We traced the cause, restored service by disabling CloudWatch logging, and added a logging check at container startup.
  • Addressed flaky tests that kept recurring across PR and release pipelines, many of them tied to timestamps or live network requests.
  • Led the migration of the sharded MongoDB cluster behind donation campaign pages and email templates from self-managed EC2 to MongoDB Atlas with zero customer-facing downtime, and of the Kong API platform from EC2 to ECS.
  • Mentored engineers through GoFundMe’s mentorship program.
