Top Rated Plus | $200k+ Verified Earnings | 6,500+ Logged Hours If you are looking for a veteran AI automation expert, n8n architect, Zapier integrator, or senior Python/Node.js backend engineer to deploy production-grade AI systems, you have found the right profile. With nearly 6,000 hours of custom API and backend engineering delivered on Upwork, I don't build brittle, low-code wrappers. I engineer highly reliable, secure, and token-optimized autonomous workflows that scale cleanly under heavy production traffic. 🚀 High-Intent Solutions I Deploy for Enterprise Clients Autonomous Agentic Workflows: Multi-agent pipelines (built with LangGraph, CrewAI, or Flowise) that automatically capture data, enrich profiles via scraping, and execute complex logic. Self-Hosted & Cloud n8n/Make Infrastructure: Setting up resilient automation hubs with custom error handling, webhooks, and state persistence. Serverless Edge AI Automations: Deploying lightning-fast, globally distributed agentic backend logic using Supabase Edge Functions and TypeScript.

When real-world payloads change, rate limits hit, or recursive loops drain your token budget, their systems break. Clients choose me because of my deep, foundational roots as an API Integration Architect and Full-Stack Engineer Because I understand custom database schemas, state management, and strict schema validation, I approach automation like a core software application. Your workflows will be built with enterprise-grade error catching, automated retries, and ironclad API data boundaries. How We Initiate Your Project To bypass the typical back-and-forth guessing games, send me a brief message detailing: 1. The current manual bottleneck or system integration problem you are facing. 2. The core software tools your business is currently running. 3. The specific operational outcome or ROI you want to hit first. I will review your brief and reply with a clear, engineering-first roadmap, structural recommendations, and an execution timeline.
