If you need a Make.com automation that leverages AI, I'm here to help. I am an expert in building complex Make.com integrations that seamlessly connect with LLMs such as ChatGPT, Perplexity, and Claude, as well as various modules like HubSpot, Pipedrive, Google Suite, WordPress, LinkedIn, and many more. Whether you're looking to streamline workflows, enhance productivity, or optimize data automation, I can create tailored solutions to meet your needs.

I turn AI-generated ("vibe-coded") apps into secure, scalable, production-ready software and build the custom backends that no-code automation (Zapier, Make, n8n) simply can't handle. 🌟 Top Rated Plus | 100% Job Success | 6,400+ Hours | 7+ Years Experience | Flexible US/EU/AU Time Zone Coverage | NDA Ready What I focus on: ✅ Production-hardening AI-generated MVPs Did you build your app with Cursor, Lovable, Bolt, Replit, or any AI coding tool? I secure it (auth, RLS, rate limiting), fix performance, and deploy it scalable enough to handle real traffic (hundreds to thousands of users), on whatever cloud you use. ✅ Taking over "vibe-coded" apps & unfinished logic Is your app stuck mid-build, or written in a language you don't want to touch? I don't care what language it's in. I'll take over and build the remaining challenging backend logic, deployed scalable and production-ready on AWS Lambda, GCP Cloud Run, Azure App Service, or your own infrastructure. Strongest with AWS and GCP, solid experience with Azure. ✅ Solving what automation tools can't Have Zapier, Make, or n8n hit their limits? Custom business logic, third-party database validation, high-volume API requests, guest/user validation flows, fully customized PDFs generated from HTML templates: I build secure custom backends in Python or Node.js for exactly these cases, deployed on AWS Lambda or your cloud, properly authenticated so no one else can touch them. ✅ Standard automation, done right Still copying and pasting between tools by hand? Any platform with an API can be automated end-to-end with Zapier, Make, or n8n, saving you thousands of hours of manual work. 🧩 Tech I work AI: OpenAI, Claude, Gemini, Vertex AI, AWS Bedrock, LangChain, Whisper, ElevenLabs, RAG, AI agents, voice AI, text-to-speech/speech-to-text, image & video generation Automation: Zapier, Make/Integromat, n8n, Pabbly, Airtable, Typeform/Jotform, ClickUp, Trello, Notion, Slack Backend: Python (FastAPI, Flask, Django), Node.js, TypeScript Frontend/Mobile: React, Next.js, React Native (Expo), including OTA updates for iOS & Android Cloud: AWS (Lambda, EC2, S3, CloudFront, CloudWatch, Cognito, SES, Bedrock), GCP (Cloud Run, Vertex AI, BigQuery), Azure App Service, Docker, CI/CD Data: Supabase (incl. RLS), PostgreSQL, MongoDB, Firestore, BigQuery, MySQL Integrations: Stripe, Shopify, HubSpot, GoHighLevel, Kartra, DialPad, SmartLead, Apollo, Clay, QuickBooks Recently: built and shipped MessageFuture, a full AI-powered web + mobile app (React Native/Expo), solo-funded, launched on Product Hunt. Primary languages right now: JavaScript/TypeScript (Next.js, Node.js) and Python. I'm language-agnostic though, and happy to work in whatever your codebase already uses. If your AI-built MVP needs to survive real users, your app is stuck mid-build, or you need automation that actually holds up, let's talk. Preference: fixed-price, milestone-based, or retainer engagements. Open to hourly only when required.
