Nexus Pathway

Nexus Pathway is a course that helps you move from "local developer" to "production-ready engineer" in Ruby. 🌐
After Zenith Pathway, you know how to build clean architecture and test code. Now it's time to cover everything that happens after "bundle exec rails s": deployment, monitoring, security, legacy handling, observability, and avoiding common production pitfalls.

What’s included
9 modules with videos, real production examples, configs, scripts, exercises on tool setup, and real incident analysis.
Module 1: Advanced tooling & environment management
rbenv vs rvm vs asdf • chruby • gemsets vs bundler groups • multiple Ruby versions
Module 2: Deployment patterns
Capistrano vs Kamal vs Docker + Compose • zero-downtime deploy • blue-green / canary basics
Module 3: Containerization & Orchestration intro
Dockerfile best practices • multi-stage builds • simple Kubernetes manifests for Ruby apps
Module 4: Observability stack
Prometheus + Grafana • OpenTelemetry basics • structured logging (lograge, semantic_logger) • error tracking (Sentry, Rollbar)
Module 5: Security in Ruby apps
Brakeman, bundler-audit, secure_headers • OWASP top 10 in Ruby context • secrets management (dotenv vs Vault)
Module 6: CI/CD pipelines
GitHub Actions / GitLab CI examples • parallel testing • auto-deploy on merge • gem caching
Module 7: Legacy code handling
Strangler fig pattern strategies • characterization tests • golden master testing • gradual refactoring
Module 8: Scaling & resilience patterns
Circuit breaker, retry, rate limiting • sidekiq pro features • database connection pooling tuning
Module 9: Final capstone exercise
Full production setup: Docker + CI + observability + secure config + deploy script for a simple Ruby service

Who this course is for
Suitable if you:

• already have experience deploying Ruby apps but want modern, resilient practices
• face downtime, slow deploys, or production complexities
• plan to work in teams where code lives for years, not months 🚀

Not suitable if you:

• have not yet written production code or dealt with real servers
• are looking only for "how to run on Heroku" without depth

What you will study
How to set up stable environments and tools for multiple Ruby versions
Different deployment strategies with minimal downtime
How to build observability without expensive SaaS (or with them)
How to detect and fix security issues in Ruby code
How to handle legacy code without full rewrite
