Hi, I'm Ethan K. Francis

Platform Engineer I build and run the systems teams depend on, including automation, reliability, and clear alerts when something breaks Automation, Observability, and Machine Learning Go, Python, and automation, plus hands-on learning for running models in production Collaborate, Learn, and Ship Work That Matters Passionate about high-impact projects with talented, collaborative teams

Writing

Why Random Forest was my first production model Decision trees, ensembles, and why I decided a simple tree model was the right starting point for my project Trunk-Based Development vs Long-Lived Feature Branches I am breaking a long-lived branch habit and learning to keep main honest with short branches and frequent merges Demystifying ADRs A simple way to write down why you made a big decision, so you can actually find the answer later.

I'm currently working on…

Media Vertical Modernization Leading how we modernize legacy media workflows without stopping production Concourse to RabbitMQ Pipeline Migration Moving a Go pipeline from CI orchestration to message queues with a safe place for failed jobs Learning C++ A lower-level language with more control and more responsibility, worth understanding even if it is not my daily driver

I'm planning to work on…

Cache-Aside API Go API that checks Redis first, falls back to the database, with metrics on hits and misses Search API Python search API backed by OpenSearch to index documents and run full-text queries Event Patterns Hands-on Go demos for RabbitMQ and Kafka, comparing queues and event logs side by side

I've also worked on…

This is a non-exhaustive list of selected projects.

Kube Pod Self-Healer Watches failing Kubernetes pods and auto-fixes common problems like crash loops and out-of-memory kills Observability Toolkit Custom metrics plus deliberate failure tests to prove monitoring and alerts actually work ML Production Pipeline Train a model, serve predictions, and get alerted when live data drifts from what it learned on Edge Observability with Prometheus Custom Cloudflare metrics exporter for fewer false alerts and a clearer picture of edge traffic OpenSearch Migration at Scale Led ElasticSearch to OpenSearch migration with single sign-on and staged rollouts per environment RabbitMQ Video Processing Pipeline Queue-backed video resize API that accepts requests fast and does heavy work in background workers
