Hi, I'm Christopher, a software engineer passionate about solving complex problems, driving positive environmental change, and the power of collaboration. As a career transitioner with experience as a former small business owner and musician, I offer a unique blend of skills and perspectives to every team I join.
Most recently, I co-created Twine, an open-source auto-scaling WebSocket infrastructure that provides web applications with real-time communication capabilities. Deployed onto a user's AWS account, Twine maintains developer control over each service's infrastructure and data, and provides out-of-the-box connection state recovery, ensuring data is never lost due to a dropped WebSocket connection.

✔️Built remotely with three teammates from different parts of the world, Twine provides an auto-scaling WebSocket infrastructure that deploys under a developer's AWS account, without compromising credentials.
This infrastructure includes a load-tested pub/sub mechanism that developers access through a secure API, and automatic client connection state recovery. Additionally, it persists all published data as a backup, and gives developers complete control of their data and WebSocket infrastructure.
Twine drops into existing web applications via the Twine client and server libraries.
Technologies Used - TypeScript, Socket.IO, Docker, and AWS (DynamoDB, Elasticache for Redis, EC2, ALB, ELB, CloudFront, S3)
At LoadUp, I independently owned and built critical systems within a platform that matches moving and junk removal customers with local service providers.
I kept $35M in annual revenue flowing across 152,000+ transactions by upgrading and maintaining Stripe payment infrastructure, HubSpot data synchronization, and Sidekiq-driven reporting pipelines. I cut search times for common queries by 70%+ by independently designing and building Elasticsearch from scratch, reindexing tens of millions of records into a dedicated Bonsai cluster.
I built the API powering LoadUp's booking tool end to end in 6 weeks, now handling 90%+ of the company's customer traffic on a site that sees roughly 10,000 visits a day. I engineered the API connecting Kustomer AI to our application and customers, enabling thousands of automated quote creations without manual admin work, and launched the platform's first quoting system, giving sys admins the ability to create custom-priced quotes for customers to view and pay online.
I also set up Datadog dashboards and alerts that surface build and release logs instantly on deployment failure, giving the team its first visibility into failed deployments, and researched and architected an event-driven pub-sub system to consolidate outgoing communications to customers, service providers, partners, and internal users into a single mechanism.
Technologies Used - Ruby on Rails, PostgreSQL, Elasticsearch, Redis, Stripe, HubSpot, Kustomer, Sidekiq, Datadog, AWS
