About me
I help founders turn fragile prototypes and single-customer web apps into secure, maintainable SaaS products.
My focus is React, Node.js, Express, TypeScript, MongoDB, PostgreSQL, authentication, Stripe billing, MCP integrations, API architecture, and multi-tenant systems.
I can rescue AI generated apps, connect AI clients to business systems through secure MCP servers and convert existing products into organization based SaaS platforms with isolated data and rolebased access.
My deliveries include source code, testing notes, clear documentation, and honest reporting of remaining risks.
