Hiring Manager
Snapfix
Dear Hiring Manager,
Snapfix's mission to streamline property management workflows resonates with the infrastructure challenges I love solving. At Oolio, I reduced API response times by 40% across our tenant experience platform while maintaining strict reliability SLAs. Returning to Snapfix feels like a natural next step, given my history with your codebase.
During my tenure at Oolio, I migrated legacy PHP services to a Go/Kafka backbone that now handles 6 million requests per month with zero downtime incidents. Our CI/CD pipelines, built on GitHub Actions and Terraform, allowed the team to ship weekly without compromising security or quality gates.
Previously at Snapfix, I authored the initial property API and established the observability practices that keep engineering and operations aligned. I enjoy mentoring engineers through the balance of shipping features quickly while keeping our architectural guardrails intact.
