About Me
Over the last 15+ years, I have built and shipped battle-tested, distributed systems that have served millions of users per month. These days I pair that experience with modern AI tooling to ship faster at scale. The aptitude to understand your business requirements and the extra mile I will put in to acquire novel domain knowledge - the human aspects of the craft is what separates me from vibe coders.
Featured Work
Shopify Like E-Commerce SaaS
I built a full-stack Next.js e-commerce platform that works a lot like Shopify. It includes a custom sandboxed engine for safely running merchant themes, an automated build pipeline, and all the underlying AWS infrastructure managed via Terraform.
View details →SMS Delivery Platform
A high-throughput messaging platform written in Go. I designed it to reliably push out over 400k text messages daily across multiple brands, making sure we never miss a delivery or break SMS compliance rules.
View details →Central Data Pipeline Service
I built this central Node.js pipeline to route analytics from over 20 different apps into Snowflake. It processes 60+ event types with exactly-once delivery guarantees, all while maintaining a flat memory profile.
View details →Marketing Analytics Data Platform
An end-to-end platform built with Go and Node.js that turns raw ad traffic into actionable ROI metrics. It catches click events at the edge, ties them to ad spend across different networks, and warehouses everything in Snowflake.
