Eleven years shipping enterprise platforms for Verizon, JPMC, Capital One, AmEx and TGen — now pointing that discipline at GenAI systems.

Built for scale, tuned for teams.

I lead cross-functional teams that break monoliths into microservices, move workloads onto AWS, and put clean, fast interfaces in front of millions of users. From reactive Java 21 backends to micro-frontend React apps, I've spent a decade making enterprise software feel less enterprise — and more like a product people actually enjoy using.

Enterprise rigor, applied to GenAI.

PILLAR 01

GenAI Building Blocks

LLM APIs, prompt engineering and structured outputs — wired into the Java, Spring and React systems I already ship.

› Claude · GPT · Spring AI
PILLAR 02

RAG & Context Engineering

Retrieval pipelines, chunking, embeddings and context design over enterprise data stores.

› LangChain · pgvector
PILLAR 03

Agentic Systems

Multi-step agents with tool use, planning and orchestration — production patterns, not demos.

› LangGraph · MCP
PILLAR 04

Fine-tuning & Local Models

LoRA / QLoRA adaptation and local inference for private, cost-controlled deployments.

› Unsloth · Ollama
PILLAR 05

Evals & Observability

Retrieval-quality scoring and full-trace observability — treating AI quality like uptime.

› RAGAS · Langfuse · Phoenix
PILLAR 06

AI Security & Safety

Guardrails, PII handling and red-teaming — the posture I applied to PHI and payments data.

› NeMo · Presidio · Garak

The thesis is simple: the teams that win with AI are the ones that already know how to run production systems. A decade of encrypted data transfer, RBAC, observability and CI/CD is exactly the foundation GenAI engineering needs.
