API Keys and Secrets Hardcoded in Source Code
Claude Code generated code with API keys, database passwords, or other secrets hardcoded directly in source files. These credentials are now committed to your Git repository and visible to anyone with access to the code.
This is one of the most common security mistakes in AI-assisted development. The AI often places real credentials inline to make the code immediately functional, without considering that the code will be version-controlled and potentially shared.
You may discover this when GitHub sends a secret scanning alert, when a third-party service notifies you of leaked credentials, or when you notice unexpected charges on your cloud account.
Error Messages You Might See
GitHub Secret Scanning: API key detected in commit
Warning: Possible credential leak found
Authentication failed: API key has been revoked
Billing alert: Unauthorized usage detected on your account
Common Causes
- Credentials pasted into prompts — You shared API keys in your prompt and Claude Code embedded them directly in the generated files
- No .env file pattern — The generated project doesn't use environment variables or a .env file for configuration
- Missing .gitignore — Even if a .env file exists, it's not listed in .gitignore and gets committed
- Config files with real values — Application config files (config.json, settings.py) contain production credentials as defaults
- Test files with real keys — Integration tests or seed scripts use actual API keys instead of test/mock credentials
How to Fix It
- Search your entire codebase — Use tools like trufflehog, gitleaks, or grep for patterns like 'sk-', 'AKIA', 'ghp_', or 'password=' across all files and Git history
- Move all secrets to environment variables — Replace hardcoded values with process.env.KEY_NAME or os.environ['KEY_NAME'] and create a .env.example with placeholder values
- Rotate every exposed credential immediately — Generate new keys for every service whose credentials were committed, even if the repo is private
- Scrub Git history — Use git filter-branch or BFG Repo Cleaner to remove secrets from past commits
- Add pre-commit hooks — Install detect-secrets or gitleaks as a pre-commit hook to prevent future leaks

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.

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.

I build and fix web apps across Next.js, Node.js, and DBs.
Comfortable jumping into messy code, broken APIs, and mysterious bugs.
If your project works in theory but not in reality, I help close that gap.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
Are my API keys compromised if they were in a private repo?
Treat them as compromised. Private repos can be forked, cloned by team members, or exposed through CI logs. Always rotate keys that were ever committed to any repository.
How do I remove secrets from Git history?
Use BFG Repo Cleaner or git filter-repo to rewrite history. After cleaning, force-push and have all collaborators re-clone. The old commits may still exist in forks or cached copies.
