About

Senior Software Engineer with 7 years of full-stack experience. Architected high-availability systems, real-time AI orchestration layers, and localized LLM pipelines on AWS. Focused on measurable impact: 60% query latency reduction, 90% bundle size cuts, and a 92% automated extraction success rate.

  • Systems performance

    I track down broken or slow systems and fix the root cause. MongoDB replica sets, PM2 cluster tuning, compound index design, DOM virtualization โ€” I find the bottleneck and eliminate it with numbers to back it up.

  • Full-spectrum engineering

    From WCAG-compliant Angular/React UIs for 15+ colleges in the SBCTC portal, to React Native mobile apps, to real-time Socket.io orchestration layers, and pre-production Azure VM environments.

  • AI pipeline architecture

    I built 40+ end-to-end IDP pipelines with custom OCR logic, NLP training, and a multi-stage LLM verification loop on AWS that achieved a 92% automated extraction success rate across 8,000+ college transcript templates.
