About this gig
Need a working product to show investors or your first customers, not just a design file? I'm a senior full-stack engineer (9+ years) and co-founder/CTO of live SaaS products (Skillramp, Financialia). I build MVPs end to end: authentication, database design, core business logic and a clean UI, all in one go. Stack: Next.js and React on the frontend, Node.js and NestJS on the backend, PostgreSQL or MongoDB for data, deployed and ready to demo. If your MVP needs payments, I integrate Stripe or MercadoPago directly, no bolted-on plugins. I also work AI into the product when it makes sense, from my other gig integrating Claude and GPT into existing apps. Every package includes source code and a walkthrough call before final delivery. Tell me about your product and let's scope it together.

Senior full-stack engineer (9+ years) and co-founder/CTO of live SaaS products (Skillramp, Financialia) plus my own studio, Totora. My specialty is integrating LLMs (Claude, GPT) into real production systems, not demos, products with real payments, users and data. I work across TypeScript, React, Next.js, Node.js, NestJS, PostgreSQL and MongoDB, combined with prompt engineering, output validation and multi-agent orchestration. Need AI added to your existing product, or a full SaaS or website built from scratch? Let's talk.
FAQ
Do I get the source code and can I host it myself?
Yes. Every package includes full source code, and you own it and can host it on any provider you choose.
Can you integrate AI into the MVP too?
Yes, that's actually my specialty. Mention it when we talk and we'll scope it into your package.
