Selected Leidos & Infra Work

Mission-critical projects at Leidos (July 2023 – present): agentic AI platforms, decentralized VPN mesh, zero-trust systems, and full-stack tooling where reliability, security, and scale lead.

Agentic AI & Intelligent Analytics

Enterprise-scale platform for natural language queries over 36M+ publications with semantic search and graph analytics.

Architected an intelligent analytics platform using Pydantic AI and Model Context Protocol (MCP) with dual MCP servers (Neo4j MCP + custom FastMCP). Semantic search via LiteLLM embeddings (768-dim vectors) and cosine similarity on a Neo4j knowledge graph; sub-5-second query latency for complex traversals. Zero-trust security: Kubernetes NetworkPolicies, Istio mTLS, API auth, RBAC, data protection, audit logging. Production ETL with Apache Airflow 3.1.3 and KubernetesExecutor; solved a critical Airflow 3.1.3 SDK DAG serialization bug via custom wrapper and plugin. GitOps-based Kubernetes (Fleet/Rancher) for GenAI workloads with 99.5%+ uptime and zero-downtime deployments. Neo4j StatefulSets with 200Gi persistent storage; human-in-the-loop elicitation and self-improving tool patterns.

Cyber Resiliency Network

High-performance decentralized VPN mesh, network visualization, and LLM observability.

Architected a high-performance decentralized VPN mesh using FD.io VPP, DPDK, and IPSec (IKEv2): multi-hop encrypted routing across OpenStack and bare-metal with Intel QAT acceleration. Go-based gRPC control plane for distributed tunnel orchestration (GoVPP, BoltDB); no single point of failure. Built Synoptics—full-stack network visualization: D3.js SVG interactivity, React state, Python heartbeat engine, Draw.io Embed API for in-app diagram authoring and monitorable SVGs. Designed LLM observability with Langfuse and Apache Superset: normalized MySQL ETL, batch processing, idempotent upserts, executive BI dashboards. Optimized C++ inference (ResNet50, Intel AMX/IPEX) and PYG GCN node classification; deployed split-learning Flower framework on the de-VPP VPN mesh.

Zero Trust Document Management

Multi-container document system with capability validation and identity integration.

Architected a Zero-Trust Document Management System: Java Spring Boot microservices, React application, AWS EKS deployment, integrated Okta and F5 BIG-IP VPC for real-time capability validation.

AI Palooza 2025

Company-wide Sim2Real object detection challenge using synthetic data and YOLO.

Collaborated in the internal AI innovation challenge: trained YOLOv11 models with synthetic datasets from NVIDIA Isaac Sim and Omniverse Replicator; evaluated with mAP@[.50:.95] and IoU. Focused on Rubik’s Cube and AprilTag detection; explored Sim2Real generalization and small-object limits. Ranked 12th of 27 teams; presented technical findings to internal engineering audiences.
