Top Rated Plus | 100% Job Success | 8+ Years on Upwork I am a Full Stack Developer focused on building production-ready web applications that perform reliably under real-world conditions. My work sits at the intersection of full stack development, JavaScript engineering and scalable SaaS platform development, with a strong emphasis on clean architecture, performance, and long-term maintainability. As a Developer, I take ownership of applications end-to-end, building backend systems with Node.js and Express while delivering modern, responsive frontend interfaces using React/Next.js. I combine the roles of frontend and backend developer into a single, cohesive workflow, ensuring consistency across the entire application rather than fragmented development across multiple resources. I have hands-on experience using Claude and Cursor to streamline development workflows, accelerate coding, and improve overall productivity. By leveraging Claude for intelligent code generation, debugging assistance, and architectural suggestions, and combining it with Cursor’s AI-powered coding environment, I’ve been able to rapidly prototype features, refactor complex codebases, and maintain clean, efficient solutions. On the backend, I specialize in building RESTful and GraphQL APIs using Node.js and Express, along with designing efficient data models in MongoDB. I have hands-on experience implementing authentication systems, role-based access control, background jobs, and integrations with third-party services. My backend approach prioritizes scalability, security, and clean separation of concerns. On the frontend, I develop high-performance React/Next.js applications with a focus on usability, maintainability, and component-driven architecture. I work extensively with modern React ecosystems, including state management, reusable UI systems, and API integrations, ensuring seamless communication between frontend and backend layers. A significant portion of my work involves building API-first platforms and integrating third-party services such as payment gateways, CRMs, analytics tools, and external APIs. I often collaborate closely with product and growth teams to implement tracking systems, reporting dashboards, and scalable backend logic that supports data-driven decision-making. I regularly work with startups and growing teams to build MVPs and production systems, with a strong focus on setting the right technical foundation from the start. Depending on the project scope, I work independently or collaborate with my team to deliver high-quality results. Long-term success comes from thoughtful system design and clean execution. I focus on building software that is not only functional today, but scalable and maintainable for the future.

I'm Gabriel, a Full Stack Developer specializing in React, Next.js, Supabase, PostgreSQL, Node.js, and AI-powered web applications. I help startups, founders, and growing businesses build secure, scalable SaaS platforms, AI products, customer portals, dashboards, and custom web applications that are ready for production from day one. Whether you're validating an idea, replacing legacy software, or scaling an existing platform, I build software that's fast, maintainable, and designed for long-term growth, not quick fixes that become expensive later. Many clients come to me after a previous developer disappeared mid-project, delivered code that nobody else could maintain, or built an MVP that started breaking as users increased. My approach is different. I understand the business first, design the architecture second, then build clean, production-ready software that your team can confidently grow. ━━━━━━━━━━━━━━━━━━━━━━━ 🔷 𝑾𝑯𝑨𝑻 𝑰 𝑩𝑼𝑰𝑳𝑫 ━━━━━━━━━━━━━━━━━━━━━━━ ➤ SaaS Platforms ➤ AI Applications & AI-Powered Workflows ➤ MVP Development ➤ Client Portals ➤ Admin Dashboards ➤ Internal Business Tools ➤ CRM Systems ➤ Marketplaces ➤ Booking Platforms ➤ Subscription-Based Applications ➤ Custom Web Applications ━━━━━━━━━━━━━━━━━━━━━━━ 🔷 𝑴𝒀 𝑫𝑬𝑽𝑬𝑳𝑶𝑷𝑴𝑬𝑵𝑻 𝑨𝑷𝑷𝑹𝑶𝑨𝑪𝑯 ━━━━━━━━━━━━━━━━━━━━━━━ Good software starts with good architecture. Before writing production code, I design the application's data model, authentication flow, permissions, billing logic, and scalability strategy. This prevents costly rewrites, security issues, and performance bottlenecks as your product grows. I write clean, maintainable code that another developer can confidently work with long after launch. ━━━━━━━━━━━━━━━━━━━━━━━ 🔷 𝑺𝑬𝑹𝑽𝑰𝑪𝑬𝑺 𝑰 𝑶𝑭𝑭𝑬𝑹 ━━━━━━━━━━━━━━━━━━━━━━━ ➤ Full Stack Web Development ➤ React.js Development ➤ Next.js Development ➤ Supabase Development ➤ PostgreSQL Database Design ➤ Node.js & NestJS Backend Development ➤ REST API & GraphQL Development ➤ AI Integration (OpenAI APIs) ➤ Authentication & Authorization ➤ Stripe Subscription Billing ➤ Multi-Tenant SaaS Architecture ➤ Real-Time Applications ➤ Third-Party API Integrations ➤ Performance Optimization ➤ Bug Fixing & Feature Development ➤ Deployment & CI/CD ━━━━━━━━━━━━━━━━━━━━━━━ 🔷 𝑻𝑬𝑪𝑯 𝑺𝑻𝑨𝑪𝑲 ━━━━━━━━━━━━━━━━━━━━━━━ Frontend: Next.js · React · TypeScript · JavaScript (ES6+) · Tailwind CSS · shadcn/ui · HTML5 · CSS3 · Redux · Zustand Backend: Node.js · NestJS · Express.js · REST API · GraphQL · WebSockets Database: PostgreSQL · Supabase · Prisma · MongoDB · Redis Auth & Security: OAuth 2.0 · JWT · Row Level Security (RLS) · RBAC AI & Integrations: OpenAI API · AI Chatbots · AI Automation · AI Workflows · Stripe · Twilio · SendGrid · Webhooks Payments & Integrations: Stripe · Twilio · SendGrid · OpenAI API · Webhooks DevOps & Deployment: Docker · Vercel · Railway · Render · AWS · CI/CD · Git/GitHub Architecture: Multi-Tenant Systems · Microservices · Serverless Functions · Edge Functions ━━━━━━━━━━━━━━━━━━━━━━━ 🔷𝑾𝑯𝑶 𝑰 𝑾𝑶𝑹𝑲 𝑾𝑰𝑻𝑯 ━━━━━━━━━━━━━━━━━━━━━━━ ➤ Startup Founders ➤ SaaS Companies ➤ Small & Medium Businesses ➤ Agencies ➤ Product Teams ➤ Entrepreneurs Launching MVPs Whether you're starting from an idea, improving an existing product, or rescuing an unfinished project, I can help you deliver software that's built for real users, not just demos. ━━━━━━━━━━━━━━━━━━━━━━━ 🔷 𝑾𝑯𝒀 𝑪𝑳𝑰𝑬𝑵𝑻𝑺 𝑾𝑶𝑹𝑲 𝑾𝑰𝑻𝑯 𝑴𝑬 ━━━━━━━━━━━━━━━━━━━━━━━ ➤ Clean, maintainable code ➤ Scalable architecture ➤ Clear communication ➤ Fast response times ➤ Security-first development ➤ Business-focused solutions ➤ Long-term thinking instead of short-term shortcuts I don't just build features, I build products that are easier to maintain, easier to scale, and easier for your business to grow around. ━━━━━━━━━━━━━━━━━━━━━━━ 🔷 𝑳𝑬𝑻'𝑺 𝑩𝑼𝑰𝑳𝑫 𝑺𝑶𝑴𝑬𝑻𝑯𝑰𝑵𝑮 𝑮𝑹𝑬𝑨𝑻 ━━━━━━━━━━━━━━━━━━━━━━━ If you're looking for a React, Next.js, Supabase, or Full Stack Developer who understands SaaS architecture, AI integrations, and scalable product development, let's talk.
