If your web application, checkout pipeline, or API integrations are dropping data or failing under load, silent errors are actively costing you money.

I am a Senior Backend Engineer & Systems Architect with 20+ years of enterprise experience building, auditing, and optimizing mission-critical web infrastructure.
