Senior Full Stack Developer, 15+ yrs. Products I've built have raised $5.8M+ and reached 200K+ users. ✅ One SaaS I rebuilt hit 350+ customers and ~$3M in funding, then was acquired ✅ Platforms trusted by SoftBank & Schneider Electric. I ship products that scale, not demos For over 15 years, I've worked as a Full Stack Developer and SaaS Developer helping startups and enterprise companies design and build AI-powered, scalable SaaS platforms and high-performance backend systems. Products I've delivered span 200K+ end users and six venture-backed companies that have collectively raised over $5.8M in funding, with reports and platforms adopted by enterprises like SoftBank, Schneider Electric, and The Venture City. One product, Kleta, was acquired by Cooltra. I primarily work on mid to high-ticket projects where urgency, scalability, and production reliability matter. Here's what I deliver: ✔️ AI Integrations & LLM Systems: Full Stack Developer for AI SaaS (OpenAI, Claude, RAG) As a full stack developer for AI SaaS I've shipped 10+ LLM-powered features to production, including RAG and embeddings on my latest project, Caliper, and an AI experiment for the Max Planck Institute that drew 1,000+ participants and 20,000+ generated images. ✔️ Full Stack Developer for SaaS (React, Node.js, TypeScript, MongoDB, PostgreSQL) SaaS platforms I've built as a full stack developer have scaled to 350+ paying customers and processed nearly $3M through a single Stripe integration, and one MVP I delivered on a budget under $15K secured funding for a platform whose reports now reach enterprises like SoftBank and Schneider Electric. ✔️ System Architecture & Backend Engineering: Backend Developer & Node.js Developer As a Node.js developer I've rebuilt backend systems that lifted Lighthouse performance scores by 40%, delivering scalable architectures, RESTful APIs, database optimization (MongoDB, PostgreSQL), and AWS cloud deployment. ✔️ Frontend Engineering: React Developer & Next.js Developer Front-end revamps I've led as a React developer have increased user engagement by 40% and marketing efficiency by 20%, with responsive, high-performance interfaces and clean UX. ✔️ Data & Integration Systems: API Integration Specialist Complex data integrations, analytics tracking (PostHog, Google Analytics), CRM integration, and performance optimization for real-world web applications. It's only possible because of my full stack developer capabilities. ✔️ Development Workflow & Tooling Structured, version-controlled development ensuring maintainability, faster iteration, and long-term scalability. ✔️ Collaboration & Agile Delivery Efficient communication and delivery using Slack, ClickUp, Jira, or good ole GitHub Projects and structured agile workflows. ⭐ Recent Client Feedback "Great communication and attention to detail. Planned carefully and delivered high-quality work. Would gladly work with Mateen again." "Stayed on budget and delivered exactly what we needed. This was a repeat engagement and won't be the last. Highly recommended." Let's start with a focused consultation. As your full stack developer I'll review your idea, identify risks early, and map out a scalable SaaS system built for real users.

Let's talk if you need a Senior Full Stack Engineer who can own web, mobile, SaaS, & AI Solutions.

I’m a full stack developer, react developer, and web developer helping businesses build, fix, and improve SaaS products, web applications, dashboards, internal tools, and client platforms with react, next.js, node.js, supabase, postgresql, API integration, and AI-powered workflows. As a full stack developer, I work across front end and back end development. As a react developer and next.js developer, I build and improve modern web application interfaces, dashboards, admin panels, and client-facing product flows. As a node.js developer, I work on business logic, API integration, authentication, webhooks, oauth, stripe flows, and product functionality that supports real SaaS and web application use cases. My work often combines react, next.js, node.js, javascript, typescript, supabase, and postgresql inside one product. Clients usually hire me when they need a full stack developer who can do more than isolated tasks. They need a react developer who can work inside a real product, a next.js developer who can improve an existing web application, and a node.js developer who can connect front end and back end logic cleanly. I help build MVPs, improve SaaS products, fix broken web applications, stabilize dashboards, extend internal tools, improve client portals, and support existing codebases that need stronger full stack development. A lot of my work is with react, next.js, and node.js products that already exist but need improvement. That can mean bug fixing, maintenance, stabilization, performance improvement, API integration, dashboard development, admin panel development, auth flow fixes, web application cleanup, SaaS feature delivery, or extending an MVP into a more production-ready SaaS platform. I’m comfortable joining an existing codebase and working as a full stack developer, react developer, next.js developer, or node.js developer depending on what the product needs most. I also work with supabase and postgresql when a SaaS product or web application needs database logic, authentication, real-time functionality, role-based access, or cleaner back end structure. In many projects, react, next.js, node.js, supabase, and postgresql work together as the core stack, and that is a stack I’m comfortable building, fixing, and extending. I regularly work on web application and SaaS development that includes API integration, stripe, oauth, webhooks, dashboards, internal tools, and client-facing product flows. As a react developer, I can help build responsive product UI, dashboard UI, admin interfaces, and front end functionality inside larger web applications. As a next.js developer, I can help with product architecture, page flows, performance, routing, feature delivery, and production-ready SaaS implementation. As a node.js developer, I can help with API integration, back end logic, business workflows, third-party services, and server-side product functionality. As a full stack developer, I can connect all of those layers into one working product. I also work with AI when it supports a real SaaS or web application use case. That includes AI integration with OpenAI or Claude APIs, AI-assisted product features, AI workflows inside dashboards and internal tools, and automation that supports web application, SaaS, or client platform functionality. When useful, I can also support web scraping and automation if it fits the product and strengthens a real business workflow. If you need a full stack developer, react developer, next.js developer, node.js developer, or web developer for a SaaS product, web application, dashboard, internal tool, API integration project, MVP, client portal, supabase app, postgresql-based system, or AI-powered product feature, send me a message and I’ll review your project.

I help SaaS founders move from "idea" to revenue-generating product in weeks, not quarters. For 10+ years, I've built full-stack systems for startups and scaling companies. The last 5 years? AI-first development—taking the latest LLM breakthroughs and turning them into products that actually work. What I Deliver AI SaaS Products From concept to launch-ready: multi-tenant SaaS platforms with AI built-in. Chatbots with memory. Agents that use tools. RAG systems that reason over your data. Not toys—production systems handling real business logic. Support Automation at Scale A recent client was burning $12K/month on support volume. 6 weeks later, their RAG agent handles 73% of tickets autonomously. Margin-positive from day one. Full-Stack Architecture Scalable backends (Python/Node), pixel-perfect frontends (React/Next), integrations that work, infrastructure that doesn't break at 3 am. Clean, modular code built for growth. 🏆 My Track Record 10+ years building production systems 100% Job Success + $50K+ earned on Upwork Senior engineer across startups, agencies, and enterprise ⚡ Tech Stack Python · FastAPI · Node.js · React · Next.js · LangChain · Claude/OpenAI APIs · PostgreSQL · Docker · AWS · n8n 💬 Let's Talk Serious about your SaaS?
