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.

I build automation systems that remove repetitive manual work from your business using Claude, n8n, and custom AI agents. Most businesses don't need "more AI." They need someone who can turn Claude Code, Claude's API, and workflow tools like n8n into a system that actually runs without babysitting. That's what I do.

Important processes lived only in her head and every day felt like she was just trying to keep things from falling apart. This is exactly what happens in many businesses without proper systems in place. Leads come in… but there’s no structured way to track or follow up. Tasks get done… but there’s no clear process to repeat them. Important steps are skipped… because nothing is documented. Notion workspace helps you build systems that organize your business, track everything, and make your workflow easier. In fact, if your Notion workspace needs a tutorial every time someone logs in… it’s already broken. or you have not standardize vital roles or processes in your business using SOPs. 𝐓̶𝐡̶𝐚̶𝐭̶ ̶𝐧̶𝐞̶𝐞̶𝐝̶𝐬̶ ̶𝐭̶𝐨̶ ̶𝐒̶𝐓̶𝐎̶𝐏̶!̶ Most setups are either overdesigned or overengineered and both kill productivity. What you need is a simple process to track any progress you are making.

A SaaS founder was manually answering client messages until midnight every night. I built an AI chatbot in 2 weeks. It now handles 257 conversations monthly, serves 532 clients, and cut their costs by 43.8%. I build AI-powered SaaS products that save time and generate real revenue from day one. I am a Multi-Tenant Full-Stack SaaS Developer with several years of experience building production-grade, AI-powered SaaS platforms from concept to launch across HealthTech, FinTech, EdTech, and B2B industries.

When you hire me, you're not just getting a developer who writes code. You're getting a technical partner who thinks about your product, your users, and your growth. ━━━━━━━━━━━━━━━━━━━━━━━━ ► CORE SAAS EXPERTISE ━━━━━━━━━━━━━━━━━━━━━━━━ • AI-powered SaaS platforms • OpenAI, Claude & Gemini API integration • RAG pipelines & vector databases • Multi-tenant SaaS architecture • Stripe billing & subscription systems • SaaS MVP development • Real-time dashboards & analytics • API-first backend systems • Cloud deployment & DevOps ━━━━━━━━━━━━━━━━━━━━━━━━ ► AI & LLM CAPABILITIES ━━━━━━━━━━━━━━━━━━━━━━━━ • OpenAI, Claude & Gemini APIs • LangChain workflows • RAG architecture • Vector search (pgvector, Pinecone) • AI automation systems • Prompt engineering & AI workflows ━━━━━━━━━━━━━━━━━━━━━━━━ ► TECH STACK ━━━━━━━━━━━━━━━━━━━━━━━━ Frontend: Next.js 14/15, React 18+, TypeScript, Tailwind CSS, shadcn/ui Backend: Node.js, PostgreSQL, Supabase, Prisma ORM, Redis Cloud: Vercel (Top 0.06% globally), AWS, Railway, Docker Payments: Stripe Billing, Stripe Connect, usage metering, subscription logic ━━━━━━━━━━━━━━━━━━━━━━━━ ► WHAT I BUILD ━━━━━━━━━━━━━━━━━━━━━━━━ • AI-powered SaaS applications • Multi-tenant B2B SaaS platforms • Real-time analytics dashboards • LMS platforms with AI content generation • CRM & workflow automation systems • AI-integrated MVPs for startups ━━━━━━━━━━━━━━━━━━━━━━━━ ► BEST FIT IF YOU'RE ━━━━━━━━━━━━━━━━━━━━━━━━ • A founder looking for a technical partner to build your SaaS • A team adding AI to an existing product without breaking what works • A startup shipping a scalable MVP fast • A product team that values communication, scalability & clean architecture ━━━━━━━━━━━━━━━━━━━━━━━━ ► WHY FOUNDERS CHOOSE ME ━━━━━━━━━━━━━━━━━━━━━━━━ I think like a technical partner, not just a coder Production-ready systems designed to scale Clear daily communication & on-time delivery Clean, maintainable architecture from day one 100% Job Success — every client satisfied If you're building a SaaS product and want it done right from the start — scalable, production-ready, and AI-ready — let's talk.

Still doing work by hand that should run on its own? Customer messages piling up, social posts taking hours to schedule, your team juggling five tools that don't talk to each other? I build AI automation systems that fix exactly that, so your business runs smoother without you having to think about it. I'm a full-stack developer who specializes in AI automation, not someone who connects three nodes in Zapier and disappears. Whether it's automating customer service replies, building a chatbot that actually understands your business, syncing your CRM and Slack so nothing falls through the cracks, or scheduling content across every platform you use, I design systems that keep working long after the project ends. No fragile setups. No black boxes. No dependency on me to keep it alive. What I automate • AI customer service: emails, DMs, and chat replies handled automatically, with human handoff when it matters • Social media: AI captions, hashtags, and descriptions auto-posted across Instagram, TikTok, Facebook, and YouTube Shorts from one upload • Slack and CRM: communication flowing into one place with AI summaries, dashboards, and blind-spot detection • Workflow automation and AI agents: scheduled, multi-step automations that run your repetitive operations without manual input • Chatbots and phone agents: answering common questions, qualifying leads, handling routine conversations • Zapier and Make to n8n migrations: same automations, better reliability, lower monthly cost, full execution logs • Custom API and integration work: connecting CRM, SMS, phone systems, and Google Workspace into one smooth operation AI built into your real tools • Claude, ChatGPT, and OpenAI API integrated directly into your existing workflows • AI agents built with Claude Code and MCP server setup to extend what they can do • Google Sheets and Workspace agents that read, write, and edit live data for inventory, reporting, and CRM • Voice and phone agents for calls, appointment handling, and routine inquiries When you need more than automation Sometimes the automation needs a real backend behind it. I build that too: Django, FastAPI, and Next.js, architected and deployed production-ready so the system holds up as you grow. How I work I figure out what's actually slowing your business down and build the system that removes it for good, with documentation so your team understands exactly how it runs. If you've got a process that should be running on its own, send me a message with what's eating your team's time and I'll tell you within 24 hours exactly how I'd automate it.
