Enterprise-Grade Web Application Firewall

Designed and built a custom WAF from scratch using ModSecurity and OWASP standards. This system protects against DDoS attacks, RCE, XSS, and other threats through intelligent rate-limiting and real-time threat detection, including stateful blocking via in-memory database LMDB.

React PWA Performance Revolution

Led the migration from jQuery, Angular to React PWA, achieving the fastest performance metrics on Slow/Fast 3G/4G. Implemented advanced optimization techniques including Brotli compression, intelligent lazy-loading, device-specific image serving with adaptive loading based on network.

Serverless Infrastructure Migration

Containerized and migrated frontend applications to Kubernetes, then optimized by transitioning burst services to serverless architecture. Built custom image service using GCP Cloud Functions/AWS lambda & Akamai CDN for device-specific adaptive optimization.

High-Throughput A/B Testing Framework

Architected a sophisticated A/B testing platform using Nginx and Akamai CDN, enabling parallel product experiments with real-time analytics and rapid feature rollout capabilities, with the ability to scale the experiments dynamically as needed. This reduced the user roll out time to 3 weeks.
