selected work
-
RAG chatbot for a major U.S. mall operator
A chatbot demo built for a major U.S. mall operator to answer shopper questions about stores, hours, promotions, and events. Used Next.js, React, Python, OpenAI APIs, and Weaviate, with AWS Lambda and EventBridge ingestion pipelines to keep tenant data current.
Demonstrated a production-shaped RAG architecture with automated data ingestion on AWS.
-
Telemetry & content platform for digital signage
Real-time telemetry and content distribution platform powering thousands of Android digital signage players: device monitoring, content delivery, fleet analytics, and high-volume metrics ingestion using RabbitMQ, Express/Node, and TimescaleDB/Postgres.
Diagnosed production bottlenecks across EC2, disk I/O, Nginx, PM2, and database workloads.
-
Observability migration: ELK → OpenSearch
Led the migration of a legacy Elasticsearch/Kibana stack to AWS-hosted OpenSearch with Logstash pipelines. Reworked indexing resilience, lifecycle and storage policy management, and CloudWatch-backed alerting.
Reduced cloud infrastructure costs by roughly 10% while improving alerting reliability.
-
A Next.js 15, React 19, and TypeScript research app that orchestrates parallel agents, live progress, typed session state, citations, retries, timeouts, and mock/live search adapters.
Deployed as a working AI research product at agents.dagos.to.
-
A full stack platform connecting loan officers with lenders through privacy preserving, opt-in matching. Built with Next.js, Fastify, Postgres/Drizzle, and Clerk auth, with Stripe billing gating subscriber access; containerized and deployed to an AWS Lightsail VPS behind Caddy with GitHub Actions CI/CD. Also built standalone launch tooling: an SES driven, audience targeted email campaign tool with test send/confirmation safety gates, and an idempotent CSV to Postgres backfill tool for migrating beta data into production.
Shipped the full product plus the tooling that carried a beta cohort through launch.
Outside of work, on my own time, I'm building Rally — an iOS app for fans who actually show up to live games: log every game, chat with fellow fans in the stadium, and build a record of every moment you were there.

I'm always interested in hard problems, especially where cloud infrastructure, AI, and real products meet. The fastest way to reach me is email; I read everything.
