Dear [Hiring manager's name],
I build the kind of backend systems nobody notices until they fail. At Meridian Commerce I own microservices that serve more than 2 million requests a day at 99.97% uptime, and I'm applying for your Software Engineer role because your team works at a scale where that kind of reliability decides whether customers stay.
My favorite recent project was moving our storefront from a monolithic REST API to GraphQL. It cut frontend data fetching by 60% and took 1.8 seconds off page loads. Along the way I rebuilt our CI/CD pipeline in GitHub Actions, bringing deploys from 45 minutes down to 8 and production incidents down by 35%.
I work mostly in TypeScript, Node.js and React, run services on Kubernetes and AWS, and I am at home in PostgreSQL when an endpoint slows down; at Brightpath Health I took one API's p95 response time from 850 ms to 210 ms. I also mentor four junior developers, and our review and pairing habits have halved their onboarding time.
I would welcome a conversation about the systems [Company name] is building next, the reliability goals your team holds itself to, and where someone who enjoys both shipping features and hardening them could help. Thank you for your time and consideration.
Sincerely,
Casey Young
