You will get Expert Vibe Coding to Rapidly Build Your SaaS MVP
Project details
Vibe coding is completely changing how startups launch. But relying on generic prompts or basic wrappers to write a codebase often leads to fragile applications and massive security vulnerabilities.
I am Krunal, an independent Senior Architect who merges 13 years of full-stack experience with cutting-edge AI-assisted development. By utilizing advanced local setups like Claude Code combined with secure sandbox environments such as Antigravity IDE, I rapidly prototype and build enterprise-grade applications in a fraction of the traditional time.
What I Build:
• Rapid SaaS MVPs & Prototypes
• AI-Assisted API Integrations
• Complex Node.js & Prisma Backends
• State-Managed React Frontends
The Top 1% Standard:
I don't just generate code and hand it over. I actively orchestrate the AI. By running models locally and utilizing strict runtime validations, I ensure the code generated is mathematically sound, highly secure, and perfectly tailored to your business logic. You get the unprecedented speed of vibe coding paired with the absolute safety of a Fractional CTO.

WordPress Theme / Site Speed Expert
Krunal is the best freelancer I’ve worked with in 8+ years. It's immediately clear that he's an expert in his field, and he went far above my job requirements to ensure I was satisfied with every aspect of his work.
Krunal's task was to improve my website speed, and he took my Google Lighthouse speed scores up to 90+ (on mobile) and 95+ (on desktop) on virtually every page. He asked thoughtful questions throughout the project to ensure he was making the right decisions, and at the end of the project, we had a 30-minute call where he explained all of the changes he made and answered my questions about those changes.
I am extremely satisfied with Krunal's work and will hire him again whenever I get a chance. If you have the opportunity to work with Krunal, you will not be disappointed.

Full-Stack Developer | AI Gen Integration, Vibe Code & Secure Webhooks
Vadodara, India - 5:23 am local time
I bridge the gap between rapid AI development and enterprise-grade software stability. With 13+ years of experience as Senior Full-Stack Architect, I don't just write scripts; I audit, refactor, and harden AI-generated codebases so you can scale safely without technical debt.
What I Specialize In:
Vibe Code Hardening: Transforming raw AI prototypes into secure, type-safe, production-ready applications using Node.js, TypeScript, and React.
AI & LLM Integration: Engineering robust backends using OpenAI/Gemini SDKs, enforcing strict JSON schemas to completely eliminate model hallucinations.
Secure Payment & Webhook Architecture: Fixing concurrency race conditions and webhook drop issues for Stripe, PayPal, and token-based AI credit consumption models.
Database & Performance Optimization: Restructuring PostgreSQL/MySQL schemas, fixing query bottlenecks, and setting up automated retry queues.
Why Work With Me:
Production-First Mindset: I prioritize security audits and error handling over speed.
Proven Results: Successfully handles millions in transaction processing with 0 (zero) checkout error even with pay what you can infrastructure.
Clear Communication: Regular updates and transparent documentation with 11 years remote work experience.
If you have built a rapid MVP using AI and need a seasoned engineer to secure your backend, optimize your data architecture, and make it production-ready, let’s connect.
