About this gig
AI Vibe tools like Bolt, v0, and Lovable are incredible for rapidly building frontend UI. But when it comes to taking payments and managing complex backend logic, AI code often fails silently.
Founders launch their "vibe coded" MVP only to realize their Stripe webhooks are broken, users aren't receiving their purchases, and the database is completely out of sync.
I am Krunal, an independent Senior Full-Stack Architect with 13 years of experience. I step in where AI stops. I build the secure, fault-tolerant backend bridges your MVP needs to actually process revenue and scale.
What I Architect & Integrate:
Secure Stripe Checkout & Complex Webhook Handlers
Strict TypeScript REST API Bridges (HubSpot, CRMs)
Generative AI Endpoints (OpenAI, Gemini)
PostgreSQL Database Syncs with Zero Data Loss
The Top 1% Standard:
I do not blindly trust AI-generated backend code. I enforce strict runtime validation and schema sanitization. Your frontend stays fast, but your backend becomes enterprise-grade.

FAQ
Why do AI-generated webhooks usually fail?
AI tools struggle with asynchronous logic and strict API documentation. They often write webhooks that miss events or corrupt the database. I enforce strict TypeScript validation to ensure every payment syncs perfectly to your backend.
Do I need to already have a frontend built?
Yes, this gig assumes you have an existing frontend (built manually or via AI tools like v0/Bolt) and you need a Senior Architect to securely wire up the Stripe payments, external APIs, and database logic.
Can you integrate APIs other than Stripe?
Absolutely. While Stripe is the most common integration, I expertly integrate HubSpot, BoldSign, OpenAI, Gemini, and any complex REST API directly into your Node.js backend.
Will I own the integration code?
Yes, 100%. Upon final completion, you retain absolute ownership of the full source code, database schemas, and intellectual property. No vendor lock-in and zero hidden fees.
