Full Stack Developer | React, Node.js, AI Integration & n8n Automation

I'm here to build web applications and AI automations for your business to solve real problems, simplify operations, or handle the pressure of growth. Building a new product or improving an existing one, the objective stays the same: reliable performance and room to grow. Six years as a Full Stack Developer working in React, Next.js, and Node.js, plus business process automation in n8n, Make, Zapier and GoHighLevel. I've built SaaS platforms from zero, rescued stalled codebases, and shipped Shopify, Stripe, Amazon SP-API and MUX integrations into production. Because I write code, the automation doesn't stop where the no-code nodes run out: custom API calls, webhooks no connector supports, deduplication logic, error handling that alerts someone instead of failing quietly. 42 contracts from 15 clients. Two out of three jobs on my profile come from someone who hired me before. WHAT I BUILD Full-Stack Web & SaaS - React, Next.js, Node.js (Express, NestJS). PostgreSQL, MongoDB, MySQL. MVPs from zero, or rescuing codebases someone else left half-finished. AI Agents & AI Integration - OpenAI and Anthropic Claude APIs, function calling, RAG over your own documents, chatbots, MCP servers, vector databases. Workflow Automation - n8n, Make, Zapier, GoHighLevel (GHL). Lead routing, CRM sync, order syncing, payment flows. Recent work includes a Redis-queued Shopify to Airtable sync that deduplicates burst webhooks, and a Stripe payment automation across GHL and n8n. API & Systems Integration - Stripe, Shopify, Amazon SP-API, MUX, HubSpot. REST, GraphQL, webhooks, payment gateways, third-party APIs that are badly documented and still have to work. Cloud & DevOps - AWS (EC2, Lambda, ECS, Fargate, SQS, SES, S3), Docker, DigitalOcean, CI/CD. Why clients choose me: - Bug warranty - 30 days after delivery, any defect in code I wrote gets fixed at no cost. - Weekly written progress updates, so you always know where the project stands. - Code documented well enough that the next developer you hire can pick it up without me. - Post-deployment support and performance tuning - I don't disappear at launch. Message me with the problem and I'll map the shortest path to solving it. Already have a spec? Send it over and I'll build to it. Either way you'll get a plan with timeline and cost before you commit to anything.
