Stripe Test vs Live Mode Confusion
Test payments work but production payments fail. Using test keys in production or live keys in development. Webhooks not firing in right environment. Keys mixed up causing transaction failures.
Stripe has separate test and live environments with different keys. Mixing keys between environments breaks payment flow.
Error Messages You Might See
Invalid API Key provided
Authentication required
Key error: test key used in production
Common Causes
- Using test keys in production API calls
- Using live keys in development (risky!)
- Environment variables not switched between dev/prod
- Test webhook secret used with live key
- Not checking API in right mode in Stripe dashboard
How to Fix It
Use environment-specific keys:
// .env.development
VITE_STRIPE_PUBLISHABLE_KEY=pk_test_...
// .env.production
VITE_STRIPE_PUBLISHABLE_KEY=pk_live_...Always verify mode in Stripe dashboard toggle. Use test cards for development: 4242 4242 4242 4242.

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.

’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
