Summary

Principal Engineer specializing in architectural design, cost optimization, and modern stack refinement across Node.js, Angular, and cloud-native services. Designs resilient APIs, microservices, and serverless workloads, and builds CI/CD with GitHub Actions to streamline delivery across backend and frontend. Delivered 65% faster API responses and 73% lower database load via Redis caching ($5K/month savings); built S3 + CloudFront image delivery with long‑lived cache headers achieving a 92% cache hit rate, 58% lower egress, and 78% faster image loads; and implemented comprehensive cache observability in CloudWatch. Strengthened billing integrity with an idempotency framework using distributed locks, eliminating duplicate charges across 1.6M monthly transactions and removing $45K in monthly reconciliations while ensuring 100% payment accuracy. Elevated frontend performance with resource hints, preloading, code‑splitting, and lazy loading—improving TTI by 52%, FCP by 41% (4s → 1.6s), Lighthouse from 68 → 94, and cutting initial bundles by 47%. Known for integrating backend and frontend technologies to deliver scalable, high‑performing, and cost‑efficient platforms.
