I'm a Senior Software Engineer with 9+ years building at the intersection of enterprise platforms, cloud-native systems, and AI. My career spans MERN-stack applications, large-scale e-commerce modernization, AI agent platforms at Dell, and now digital twin engineering at General Motors.

I hold a Master's in Computer Science from UT Austin and am an AWS Certified Developer. I specialize in turning ambiguous, multi-team problems into opinionated, secure, self-service platforms — from RAG pipelines and multi-agent systems to Kubernetes-based architectures with full observability.

Full-Stack Delivery

End-to-end ownership across Angular/React frontends, Python & Node.js services, and PostgreSQL/Neo4j data layers.

Cloud-Native Architecture

Kubernetes-based platforms with autoscaling, rolling deployments, and full Prometheus/Grafana observability.

Digital Twin Engineering

Building large-scale digital twin and simulation platforms that model enterprise systems in real time.

AI Platform Engineering

RAG pipelines, multi-agent orchestration, and self-service agent management deployed to production.

Enterprise Security

SSO, OAuth/OIDC, RBAC, and Active Directory integration across regulated enterprise environments.

Technical Leadership

Driving architecture decisions, mentoring engineers, and aligning cross-functional teams around outcomes.

Digital Human Management Console

Flagship

Architected a full-stack platform that automates the creation, deployment, and lifecycle management of AI-powered digital agents — replacing a manual, multi-team setup with a self-service experience that deploys agents in under one minute.

  • Built a guided self-service management console in Angular with validation, RBAC, and opinionated defaults
  • Implemented enterprise SSO with OAuth/OIDC and Active Directory integration for secure access
  • Designed backend control-plane services for agent lifecycle, authentication, authorization, and rate limiting
  • Engineered asynchronous knowledge ingestion — parsing, semantic chunking, embedding, and retrieval-ready storage
  • Implemented RAG pipelines ensuring responses are grounded in permission-filtered contextual data
  • Built analytics dashboards for conversation history, usage, and system health
  • Deployed on Kubernetes with horizontal autoscaling, load balancing, and rolling deployments
  • Instrumented observability with Prometheus and Grafana for latency, error rates, and health

Selected Projects

Enterprise platforms framed by the problem they solved, the architecture behind them, and the measurable impact they delivered.

Dell Technologies

Digital Human Management Console

Problem

Provisioning AI digital agents was a manual, multi-team process that took roughly a week and didn't scale with demand.

Solution

A self-service Angular console with guided configuration, RBAC, and enterprise SSO that lets teams deploy production-ready agents in under a minute.

Architecture

Angular front end → FastAPI control plane → RAG + multi-agent orchestration → PostgreSQL & vector storage, all running on Kubernetes with Prometheus/Grafana observability.

Enterprise Analytics Platform (GARD)

Problem

Repair and service data was siloed and slow to query, making it hard for business teams to surface actionable insight.

Solution

A graph-based analytics platform on Neo4j with GraphQL APIs and React/Next.js dashboards that delivers fast, relationship-aware insights.

Architecture

Neo4j graph database → GraphQL API layer → React/Next.js dashboards, containerized with Docker and orchestrated on Kubernetes for resilience.

Lowe's E-Commerce Modernization

Problem

Lowes.com ran on a legacy monolith (WCS/JSP) with two-week release cycles that throttled delivery velocity.

Solution

Led migration to a microservices architecture on Spring Boot and Node.js with Redis caching and a modern React front end.

Architecture

Spring Boot & Node.js microservices → Redis caching → React front end, deployed via Docker/Kubernetes with GitLab CI/CD pipelines.
