## The role

I was a full-stack developer at Cambridge Analytica / SCL Group. For a stretch, I was the only person on the web team, which meant I owned everything from frontend features to server configuration.

## Numbers

- **10M+ records/day** through the Pangea data matching platform
- **Sub-second response times** for real-time data queries
- **99.9% uptime** on AWS + Kubernetes infrastructure
- **80% faster** deployments through CI/CD automation
- **4 websites** maintained solo (ca-political.com, ca-commercial.com, cambridgeanalytica.com, sclgroup.cc)

## Web platforms

I maintained all four public-facing websites for the company's political consulting and commercial divisions. That covered the full stack: frontend features, backend APIs, server config, security, performance, and mobile responsiveness.

## Pangea Data Platform

Built a data matching system using Scala, React, and Apache Drill on Hadoop. The platform ingested 10M+ records daily, ran real-time matching algorithms, and gave analysts sub-second query responses on large datasets.

## Infrastructure

Set up Kubernetes-based container orchestration and automated CI/CD pipelines that cut deployment time by 80%. Managed AWS infrastructure (EC2, S3, RDS) with 99.9% uptime across all services.
