Project details
Built something with Lovable, Replit, Bolt, Base44, or Cursor and it's stuck, broken, or not production-ready? Or want a fast build done with real backend structure from day one?
I bring full stack engineering to vibe-coded projects, fixing what's broken, finishing what's half-built, or building from scratch, then making sure it actually holds up with real users and real payments.
What I handle:
• Fix broken Supabase auth, database, or Stripe payment issues
• Repair deployment failures across Vercel, Netlify, or platform-native hosting
• Debug logic errors, broken API calls, and corrupted state
• Finish or extend apps started in Lovable, Replit, Bolt, Base44, or Cursor
• Build new MVPs using the fastest right-fit tool for your project
• Add real backend structure: multi-tenant architecture, RLS, RBAC, billing
• Migrate a prototype to a clean, custom production codebase
Most vibe-coded apps don't fail from a bad idea. They fail because they're built fast without the backend to survive real usage. That's the gap I fill, AI-speed development with senior-level architecture behind it.
Not sure if you need a fix or a full rebuild? Start with the Starter tier, I'll diagnose it first.

AI Automation Developer - Multi-Tenant Booking & Invoicing Platform (Next.js/Supabase)
Building a SaaS platform is challenging, and I needed someone who could think beyond the requirements. Shubham consistently came up with smarter, more scalable solutions and was always thinking several steps ahead. His communication was professional, his work was high quality, and he genuinely cared about the long-term success of the product. I highly recommend him and would gladly work with him again.

I build custom SaaS products, AI-powered tools, CRMs, and internal platforms for founders and businesses, from architecture and database design through production deployment.
Recent builds include: a multi-tenant CRM built from scratch, a white-label AI sales platform with voice + text agents, an AI-powered real estate underwriting platform, and an Instagram/WhatsApp lead-generation product.
I work best on projects where an off-the-shelf tool isn't enough and you need someone who can own the actual software engineering.
----------------
HOW I WORK WITH CLIENTS
I handle the full technical build: database architecture, secure authentication, AI-powered features, RAG pipelines, and custom API integrations, engineered for real users and production scale. I've also delivered entire platforms that ship under other companies' brands, so clean handoff and confidentiality are second nature whenever a project calls for it.
----------------

BUILT FOR PRODUCTION
I focus on clean architecture and reliable infrastructure, not just impressive demos. This means database schemas, secure authentication, and deployment pipelines are mapped out before I write a single line of code.
