I’m a full-stack engineer with 3 years building Python and Node.js backends, REST API security, and CI/CD automation. I like shipping measurable improvements—especially when security and reliability matter.

At Appsentinels.ai, I added schema-driven REST API validation across the platform, reducing attack vectors by ~98%. I also implemented alert throttling to cut system overhead by ~80%, and built a custom Jenkins plugin to automate DAST security scans inside customer CI/CD pipelines.

I build product-grade interfaces and dashboards, too. I created Angular dashboards for real-time cybersecurity data with reusable tables, dynamic forms, charts, and advanced search/pagination/filtering over large datasets, then improved frontend performance through refactoring, lazy loading, and client-side caching.

In AI-systems work, I’m currently shipping BD-42, a persistent AI companion with multi-tier memory architecture. I designed bounded hot-memory in Redis with TTL expiry, provider-agnostic prompt rendering using the Strategy pattern, and a resilient three-layer handler→service→store architecture so chat replies degrade gracefully when secondary extraction fails.
