CI/CD Pipeline Missing Environment Variables
CI/CD pipeline fails during build or deployment steps because required environment variables aren't available. The application starts correctly in development where variables are set locally, but fails in the pipeline with 'variable not defined' errors.
This commonly occurs when moving configuration from .env files to CI/CD secret management, or when new required variables aren't added to all environments.
Error Messages You Might See
error: environment variable STRIPE_API_KEY is not defined
undefined variable: DATABASE_URL
Cannot start application: missing required configuration
Common Causes
- Environment variable defined in GitHub Secrets but not passed to workflow steps
- Secret name in workflow doesn't match environment variable name expected by code
- Variable scoped to wrong environment (only in staging, not in production)
- Variable definition syntax incorrect for the CI/CD platform
- Secrets not accessible to workflow due to permission/role restrictions
How to Fix It
Define all secrets in CI/CD platform. Pass secrets explicitly to build steps: env: { KEY: ${{ secrets.KEY_SECRET }} }. Use distinct names for CI/CD secret vs application env var for clarity. Document required variables in DEPLOYMENT.md. Validate variables are set before build: test -n "$REQUIRED_VAR" || exit 1.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Get HelpFrequently Asked Questions
How to pass GitHub secrets to workflow steps?
Use: env: { VAR_NAME: ${{ secrets.SECRET_NAME }} } in the step definition.
Should secrets be different per environment?
Yes. Use separate GitHub Secrets for staging vs production (STRIPE_KEY_PROD vs STRIPE_KEY_STAGING).
How to validate variables at build time?
Add validation steps: if [ -z $API_KEY ]; then echo 'API_KEY not set'; exit 1; fi
