Need a MERN stack developer who can turn a SaaS idea into a production-ready product? I build React, Next.js, and Node.js apps with the billing, roles, and dashboards real users actually need. Most developers can build screens. The harder part is the system behind those screens: the data model, user permissions, payment flow, admin logic, API structure, third-party integrations, deployment setup, and the edge cases that only show up once real users start using the product. That's usually where I come in. I work best on SaaS platforms, internal tools, dashboards, CRMs, marketplaces, booking systems, real-time apps, and web/mobile products where the app is more than a basic frontend. Problems I regularly handle: - Turning a rough SaaS idea into a working MVP: frontend, backend, database, auth, payments, and deployment - Cleaning up React or Next.js apps that got hard to maintain - Fixing slow dashboards, broken APIs, unstable MongoDB queries, Stripe issues, auth bugs, and deployment failures - Building admin panels, user roles, subscription flows, notifications, messaging, reporting, and workflow automation - Integrating Stripe, Stripe Connect, Twilio, Google Maps, Firebase, OAuth, JWT, webhooks, and custom APIs - Adding AI-assisted features where they actually improve the product, not just because "AI" sounds good Recent product work: ▪️ WAWCD .com – SaaS CRM platform. Built with React, Next.js, Node.js, and MongoDB for 20K+ active users. Worked on CRM functionality, Stripe payments, Twilio messaging, and AI-assisted workflow automation. ▪️ Tournated .com – sports management platform. Built as a web platform and extended toward mobile, using Next.js, Node.js, MongoDB, and mobile-first product flows. ▪️ Prospeo .com – real estate SaaS platform. Built with React and Node.js for lead generation, data management, and AI-assisted property insights. Before writing code, I look at the product goal, user roles, database structure, API flow, payment logic, integrations, and deployment plan. Bad architecture early usually turns into expensive cleanup later, so I'd rather build it right from day one. I'm not the best fit for simple brochure sites or one-page landing pages. I'm a strong fit if you need a MERN stack developer who can take ownership of a real product, make technical calls, and ship features that hold up past the demo stage. Send me the app details, current stack, and what needs to be built or fixed. I'll come back with a practical technical plan.
