Solution Architect

15 years engineering
5+ years on AWS
2 AI platforms in flight

Solution architect with a builder mindset. 15 years of Java, Spring Boot, and AWS: enough depth to know which patterns survive contact with production. Now designing AI-native enterprise systems end-to-end: voice-first claims pipelines, document intelligence at scale, agentic orchestration with Temporal and LangGraph. Coding agents close the loop - the velocity of a team, the judgment of a veteran.

15 years building. Now designing.

TCS Dec 2009 – Feb 2014

IT Analyst

Full-stack developer on an OLAP analytics platform for AC Nielsen. Java backend, front-end UI, data analysis support. Where I learned that the boring infrastructure work is actually the important work.

Cognizant Feb 2014 – Oct 2017

Senior Software Consultant

Enterprise Java across regulated industries: State Street (regulatory reporting, REST services, in-memory cache for large datasets), NY Life (ACCORD XML transformation via SOAP/Apache CXF), MetLife (batch-to-realtime migration).

Solution Architect

Started building core policy and agency management systems in Java/Spring Boot on Kubernetes. Now architecting AI-native platforms: voice-first claims reimagination (Temporal + LangGraph), document intelligence pipelines (AWS + Gemini), and production agentic systems with Bedrock and MCP tooling.

What I bring

01

AI-Native System Architecture

Designing systems where deterministic and AI steps each own their domain - architecture sanity over AI theater. Making the hard calls: what Temporal owns, what LangGraph owns, where the audit trail must live. The judgment that stops AI sprawl before it becomes technical debt.

In practice: Claims Reimagination (Temporal + LangGraph orchestration design) - Home Vision AI (S3/SQS/Lambda + Step Functions scaling pattern)
02

AI in Regulated Environments

15 years in insurance and finance means compliance and audit trails are designed in - not bolted on after an incident. Every AI step in a regulated system needs an escape hatch, a paper trail, and a rollback path. The differentiator most AI architects lack.

In practice: Plymouth Rock claims pipeline (auditable AI decisions, Lynx eFNOL) - State Street regulatory reporting - NY Life ACCORD transformations
03

Builder Velocity with Coding Agents

Senior architects used to have a gap between what they could design and what they could build alone. Coding agents close it. I architect the system and drive implementation velocity that used to require a full team - with the senior judgment to catch what the agents get wrong.

In practice: Home Vision AI (solo: architecture through working AWS pipeline) - Market Rotation Tracker (RRG methodology built from scratch)
04

Enterprise Integration Depth

PoC to production is where most AI projects go quiet. 15 years of integration work - REST, SOAP, Kafka, GraphQL, legacy systems - means I know what the handoff to operations looks like. AI systems that can't survive enterprise integration review don't ship.

In practice: Prod Support Agent (Elasticsearch MCP, Playwright, Qdrant, n8n) - Policy Chat Agent (GraphQL APIs + RAG + per-user memory)

How I think about this stuff

01

Architecture is about boundaries, not boxes

The hardest decision in Claims Reimagination wasn't which LLM to use. It was where the AI boundary sits. Temporal owns lifecycle durability. LangGraph owns cognitive reasoning. When those domains are clear, the whole system is debuggable.

02

Regulated environments demand auditability as a first-class requirement

15 years in insurance and finance means compliance, audit trails, and failure modes are designed in, not bolted on after an incident. Every AI step in a claims system needs an escape hatch and a paper trail.

03

Start with low autonomy, earn the right to expand

The prod support agent started with workflow tools and human-in-the-loop steps. Agents that do too much too fast are hard to debug and harder to get sign-off on. Trust is a product feature.

04

The model is rarely the bottleneck

Most production AI problems are data quality, latency, and integration complexity - not model capability. I've spent more time on output validators, retry logic, and API rate limits than on prompt engineering.

05

Coding agents give architects their velocity back

Senior architects used to have a gap between what they could design and what they could build alone. Coding agents close it. I can architect the Temporal + LangGraph orchestration layer and drive implementation velocity that used to require a team. The judgment still has to be yours. That's what keeps the generated code from accumulating hidden debt.

Open to conversations about AI-native system design, enterprise agentic architecture, or the intersection of senior engineering depth and AI velocity. Not actively looking but happy to talk.
