I build modern no-code web apps using WeWeb + Supabase / Xano, integrating secure authentication, database logic, Stripe payments/subscriptions, and automation workflows with n8n, Pipedream, or Zapier. My work focuses on clean architecture, maintainability, fast delivery, and smooth user experience. Most clients come with completed designs in Figma or other tools — I translate those into fully functional frontends in WeWeb, connect them to a scalable Supabase backend, and integrate Stripe, APIs, automations, and any custom logic needed. If designs are not ready, I can also create clean, minimal dashboards and internal tools following solid UX/UI principles. What I Do No-Code Web Apps & MVPs (WeWeb + Supabase / Xano) • Multi-page apps, dashboards, portals, internal tools • Responsive front-end built with clear structure, design system and components • User authentication, RLS, database schema, backend logic Stripe Integration • One-time payments, subscriptions, metered billing • Customer portal setup & billing management • Webhooks → automations in n8n/Pipedream Automations (n8n, Pipedream, Zapier) • Data sync, monitoring, background jobs • AI workflow automation • Webhooks, scheduled triggers, API orchestration API Integrations • Third-party SaaS tools • AI APIs (OpenAI, Anthropic, Google Gemini) • Real estate APIs, scraping pipelines, document search (RAG) • Custom JS/TS functions where no-code needs extension Tools & Platforms I’ve Helped Build • EdTech platforms for schools — teacher/student/parent ecosystem with events, webinars, tutoring booking, goals, messaging, and Stripe subscription plans. • Textero — One of the first AI writing platforms with RAG document search, AI essay generation, Stripe subscriptions, and multiple API integrations (e.g Semantic Scholar). • Internal dashboards & admin tools — operational CRMs, analytics dashboards built with WeWeb, Retool, Supabase + n8n/Zapier/Pipedream. • Real estate platforms — marketplace-style apps (Airbnb-like) for room/flat sharing, with listings, profiles, booking flows, payments, and availability logic. • AI-powered real estate parsing systems — automation pipelines ingesting data from multiple sources, structuring with AI, syncing to Supabase, and triggering workflows. When I’m a Great Fit • You need a WeWeb + Supabase developer who can deliver clean, maintainable architecture • You want Stripe payments fully handled • You need APIs, automations, or AI added to your app If that sounds like your project, feel free to send me a message with your requirements and a short description of what the app should do.

Full-stack apps and n8n AI automation systems shipped to the App Store, running in production, saving businesses 15–30 hours a week. No demos. No prototypes. Production-grade systems built on React Native, Supabase, Laravel, and n8n. ───────────────────────────── 📱 REACT NATIVE MOBILE DEVELOPMENT I build cross-platform iOS and Android apps with React Native and Expo - TypeScript, clean architecture, and real device performance from day one. React Native with Expo Router, Expo SDK, React Navigation, Zustand, and React Query is my standard stack. I handle everything from component architecture to App Store and Google Play submission. Backend options I wire into React Native apps: Supabase - Supabase Auth, Supabase Realtime, Supabase Storage, Row-Level Security, Edge Functions, and Postgres full-text search Laravel - Laravel Sanctum for React Native auth, Laravel API backend with REST or GraphQL, Laravel Queues for background jobs Firebase - for teams already on the Google ecosystem React Native features I ship regularly: push notifications (Expo Notifications), offline-first sync, biometric authentication, deep linking, in-app purchases (RevenueCat), Stripe payments, and OTA updates via EAS Update. Most clients find me after a React Native developer left them with an Expo app that crashes on Android, or a bare React Native project nobody else wants to touch. I fix those too. ⚙️ N8N AUTOMATION & AI AUTOMATION WORKFLOWS I design and deploy n8n automation systems that eliminate manual work permanently. n8n self-hosted or n8n Cloud. I set it up, secure it, and build workflows your team can actually maintain. What I automate with n8n: Lead capture → CRM sync → follow-up sequences AI-powered document processing with OpenAI and Claude AI Webhook-triggered Laravel or Supabase backend actions Content generation and multi-channel distribution Invoice creation, approval chains, and payment reconciliation API-to-API pipelines between tools that were never meant to talk n8n integrations I use constantly: OpenAI, Claude AI (Anthropic), Supabase, Laravel webhooks, Airtable, Google Sheets, Slack, HubSpot, Notion, Stripe, Twilio, Mailchimp, Typeform, and custom HTTP nodes for anything else. If you've maxed out Zapier or Make (Integromat), n8n gives you self-hosted control, unlimited executions, and the logic complexity those tools can't handle. Clients typically reclaim 15–30 hours per week after their first n8n deployment. 🗄️ SUPABASE & LARAVEL BACKEND DEVELOPMENT Supabase: Supabase Postgres schema design, Row-Level Security policies, Supabase Auth (magic link, OAuth, phone OTP), Supabase Edge Functions (Deno), Supabase Realtime subscriptions, Supabase Storage with CDN, and pgvector for AI embeddings. I take Lovable or Bolt-generated MVPs and replace the toy backend with a Supabase setup that can actually handle production traffic. Laravel: Laravel REST API development, Laravel Sanctum and Laravel Passport authentication, Eloquent ORM, Laravel Queues with Redis, Laravel Horizon, Laravel Nova admin panels, Laravel Livewire, Inertia.js, and full Laravel deployment on Forge + DigitalOcean or Laravel Vapor (serverless). Laravel is my choice when a project needs complex business logic, multi-tenancy, or a robust admin layer that Supabase Edge Functions alone can't cover. Full-stack combinations I ship: React Native + Supabase + n8n React Native + Laravel API + n8n automation Next.js + Supabase + Laravel microservice Expo + Laravel Sanctum + Supabase Storage 🤖 AI INTEGRATION & AI AGENT DEVELOPMENT I integrate AI into React Native apps, Laravel backends, and n8n automation stacks not as a feature demo, but as a working system. AI services and frameworks I work with: OpenAI API - GPT-4o, Assistants API, function calling, fine-tuning Claude AI (Anthropic) - Claude 3.5 Sonnet for complex reasoning and document analysis LangChain -RAG pipelines, vector search, memory, and agent chains pgvector + Supabase - semantic search and embeddings stored directly in your Supabase Postgres database n8n AI nodes , AI automation workflows with LLM-powered decision branching AI systems I build: RAG document Q&A, AI lead qualification inside n8n, GPT-powered Laravel admin tools, Claude AI chat assistants embedded in React Native apps, and AI agents that trigger real actions not just generate text. ───────────────────────────── WHO I WORK WITH ✅ Founders who need a React Native app built right the first time Supabase or Laravel backend included ✅ SaaS teams adding React Native mobile to an existing Laravel or Supabase web product ✅ Businesses that want n8n automation to replace 15–30 hours of weekly manual work ✅ Startups with a Lovable or Bolt MVP that needs a real Supabase schema and RLS before launch ✅ Teams integrating OpenAI or Claude AI into their React Native app or n8n workflow ✅ Laravel shops that need React Native mobile added without switching their entire backend Message me with what you're building. Let's connect!

Your AI SaaS works in the demo, then breaks the moment real users hit it. I build the version that doesn't, the kind running in production right now, moving 10,000+ clinical messages a day at 99% delivery and saving one client $400K a year. RAG that doesn't hallucinate, agents that survive edge cases, multi-tenant data that stays sealed. And where it matters most, in regulated healthcare and fintech, that's the work I'm known for. WHAT MAKES ME DIFFERENT Most developers build exactly what you spec. You get someone who tells you what the business actually needs first, before you spend the budget, then builds it to last. Five plus years leading architecture, making build-versus-buy calls, and operating as fractional CTO for founders without a full-time technical hire. The rare part: shipped HIPAA-compliant healthcare systems and SEC-compliant fintech infrastructure to US standards, where audit trails and reliability are non-negotiable. Few AI developers can claim that honestly. PROVEN IN PRODUCTION The VP of Enterprise Solutions at Fukuda Denshi USA endorsed an HL7 gateway I built for their HealthMosaic platform, now moving 10,000+ clinical messages a day from 200+ hospital monitors at a 99% delivery rate, saving an estimated $400K a year. For a US fintech startup, a SEC Reg CF compliant backend with 248 passing tests and zero production bugs. What clients say: "He thinks like a product owner, not just a developer, and delivered production-ready work ahead of schedule." Justin R., VP of Enterprise Solutions, Fukuda Denshi USA "By far the best developer I've worked with. If you need someone who delivers, hire him." Carmen M., Business Consultant "Clean, well thought out design, finished weeks ahead of schedule." Jett S., Founder, NxtSzn If you're building in AI, healthcare, fintech, or any SaaS where it has to work the first time, send me what you're building. You'll hear back within a day on whether I'm the right fit, and I'll tell you straight if I'm not. WHAT I BUILD FOR YOU → AI-powered SaaS and MVPs, multi-tenant, Stripe billing, RBAC, row-level security, architected to scale from day one → AI agents, RAG systems, and intelligent automation on OpenAI, Claude, Gemini, and LangChain, built around your business logic, not wrapper demos → HIPAA-compliant healthtech, HL7, FHIR, EMR integration, clinical workflows to US standards → Fintech infrastructure, event-sourced ledgers, escrow, payments, audit-grade reliability → API and system integration, REST, GraphQL, webhooks, CRM and ERP, into existing and legacy codebases → Cloud and DevOps, AWS, Docker, CI/CD, production deployments that hold up under load CORE STACK & KEYWORDS React, Next.js, TypeScript, Node.js, NestJS, Python, FastAPI, Django · OpenAI, Anthropic Claude, Google Gemini, LangChain, RAG, pgvector, Pinecone, AI agents · PostgreSQL, MongoDB, Redis, Prisma, Supabase, Firebase · AWS, GCP, Docker, Kubernetes, CI/CD · Stripe, HubSpot, Salesforce · HIPAA, HL7, FHIR, SEC Reg CF, multi-tenant SaaS, MVP development, fractional CTO
