Work Experience

Senior Software Engineer at Exiger

October 1, 2024 - October 1, 2024

Owned full-stack development of high-throughput fraud-monitoring and credit-risk analytics platforms powering >30M daily transactions. Architected a multi-tenant insights service using Python (FastAPI) and a Node.js gateway to stream supplier-risk documents from S3 into a Pinecone vector index, enabling millisecond end-to-end retrieval for analysts. Implemented Kafka-based ingestion pipelines and cloud-native security/instrumentation enhancements to improve reliability and observability.

Senior Software Engineer at Exiger

December 1, 2024 - November 10, 2025

AI-powered compliance and supply-chain risk platforms used by federal agencies and Fortune 500 clients. Architected multi-tenant insights service using Python (FastAPI) + Node gateway; streamed supplier-risk documents from S3 to Pinecone; built gateway using API Gateway + Lambda; implemented end-to-end data flow with observability.

Senior Software Engineer at Live Safe

July 1, 2021 - July 1, 2021

Led development of Live Safe safety-communications platform enabling real-time incident reporting and mass notification across enterprise clients. Built React + React Native front ends with Redux Toolkit and WebSockets to deliver real-time updates to 100k+ concurrent users.

Software Engineer (Contract) at Thales

August 1, 2018 - August 1, 2018

Contributed to embedded and cloud systems supporting in-flight data processing and ground analytics for airline partners. Implemented C++ embedded telemetry capture with data packet compression (LZ4); developed AWS-based microservices ingesting and validating aircraft telemetry via API Gateway + Lambda; scaled to >3 TB/day.

Senior Software Engineer (Supply Chain Risk Platform) at Exiger

December 1, 2024 - November 19, 2025

As a member of Exiger's AI-powered compliance and supply-chain-risk platform team, I architected a multi-tenant insights service using Python (FastAPI) and a Node.js gateway to stream supplier-risk documents from S3 into a Pinecone vector index, enabling millisecond end-to-end retrieval for analysts. I built Kafka-based ingestion pipelines with exactly-once processing semantics, utilizing Kafka Connect and AWS Lambda to normalize over 1.2M documents per day across compliance sources. I led the development of a Next.js frontend with React Server Components, GraphQL Apollo Client, and Suspense-based streaming, reducing time-to-first-paint from 4.1s to 2.3s. I integrated Redis for query-result caching and background job queues with BullMQ, achieving ~38% latency reduction for analytics dashboards. I introduced policy-as-code using Terraform CDK and AWS IAM conditions for data-classification enforcement, reducing manual audit exceptions by >50%. I mentored five engineers on observability b
