Kaushik R.

Hi, I'm Kaushik — a full-stack and React Native engineer who builds SaaS products and marketplaces, and fixes the ones that broke on the way to launch. If your app is stuck, half-built, or quietly falling apart in production, I can tell you why and make it right. 8+ years in, most of my work is one of two things. Either a founder has an idea and needs it built properly the first time — the database, the payments, the mobile app, the admin side — without it collapsing the moment real users arrive. Or someone already has a product, often started by another developer or an AI tool, that almost works but can't be trusted, and they need someone to take it over and finish it honestly. I've done both ends of that. I built VNYX, a multi-tenant SaaS platform that resale businesses use to grade products, generate listings with AI, and sync them across marketplaces like Shopify and eBay — where multiple businesses run on the same system and none can ever see another's data, isolated on every request through a five-tier role hierarchy. And on PepsiCo's MiNegocio+, a B2B ordering platform live across 8 countries for a Fortune 50 company, I worked on React Native apps that had to keep working with no signal at all — distributors placing orders offline and syncing cleanly on reconnect, with no duplicate or lost orders. My stack is React, Next.js, Node, and TypeScript on the web, React Native on mobile, with Postgres, Supabase, and Stripe underneath. I lean on AI tools like Claude Code to move quickly — and I read every line they write, which is exactly why I'm comfortable cleaning up a codebase one started. What you're really hiring is someone who'll tell you the truth about your product, build it to survive growth, and still be around after it ships. If that's what you need, tell me what you're working on and where it hurts.
