To Trunk:

Flaky tests & broken CI have stolen more engineering hours from my teams than any other single problem. At Remind, I watched talented engineers lose entire afternoons to "it works on my machine" mysteries while our test suite flickered between green & red for reasons nobody could explain. The problem you're solving is real & I've felt it deeply.

At Coursemojo (2022-2025), I designed CI/CD pipelines using GitHub Actions & Docker for two monolithic services. Built the infrastructure that let a small team ship AI-powered educational tools reliably. The challenge wasn't writing the pipelines; it was maintaining confidence in them as the codebase grew. Every flaky test eroded trust, & eventually engineers started ignoring failures. That's the death spiral Trunk prevents.

My infrastructure experience spans 15+ years: AWS (ECS, EC2, RDS, DynamoDB, CloudFormation), containerization & orchestration, Python & TypeScript, data pipelines, & observability (introduced Datadog at Remind for container APM across 60+ microservices). At Cofense (2020-2022), I worked in security-focused environments where CI/CD reliability wasn't optional. SOC2/FedRAMP compliance meant every deployment needed to be auditable & reproducible.

The Platform/Data Engineering focus resonates strongly. Building data ingestion pipelines that handle real-time & batch data from CI systems is the kind of problem I enjoy: high throughput, diverse sources, & direct impact on developer experience. I've built similar pipelines for log aggregation, metrics collection, & event processing.

Trunk's backing (a16z, founders from Uber/Google/YouTube) & mission to treat developer experience as mission-critical infrastructure aligns with how I've approached my career. The best infrastructure is invisible. Engineers should be thinking about their product, not their tools. I'd love to help build that.
