If your daily operations are swallowed by manual follow-ups, messy CRM leads, or repetitive admin work, hiring another human isn't the answer. Building self-running AI automation is.
I am a Retell AI Certified Partner and full-stack software engineer. While 90% of automation freelancers only know how to drag nodes in Make or Zapier, I write the underlying Python code, custom error handling, and API fail-safes. When volume hits, my systems don't break down — they scale.
WHAT I BUILD (AND HOW IT MAKES YOU MONEY)
📞 1. Inbound & Outbound AI Voice Agents (Retell AI, Vapi, Bland AI)
24/7 AI Receptionists: Sub-500ms response times, intelligent caller qualification, and instant calendar booking (Google Calendar, Outlook, GHL).
Outbound Sales & Lead Reactivation: Automated cold/warm outreach bots that qualify prospects, handle objections, and live-transfer hot leads directly to your phone.
Multi-Channel Follow-Up: Unified Voice + SMS + Email + Webchat execution so zero leads slip through the cracks.
⚡ 2. Hardened n8n & Make Workflow Infrastructure
Self-Hosted & Cloud n8n Architecture: Workflows engineered with retry logic, payload validation, and custom logging.
CRM & Tooling Sync: Deep, two-way integration across GoHighLevel (GHL), HubSpot, Zoho CRM, AgencyBlock, NetSuite, and Odoo.
Custom API Integrations: Webhooks, RESTful APIs, and database mapping (Supabase, PostgreSQL, Airtable).
🧠 3. Multi-Agent AI Systems & Knowledge RAG
Autonomous AI Agents: Custom agent workflows leveraging OpenAI (GPT-4o), Claude 3.5, and local/cloud LLMs (Ollama, vLLM, DeepSeek).
Company Knowledge RAG: AI chatbots trained on your exact internal SOPs, knowledge bases, and documents for accurate support.
Rapid Prototyping & Scraping: Custom web-scraping pipelines and agent harnesses (OpenClaw, Cursor, Lovable) for complex data collection.
THE PROOF
Retell AI Certified Partner: Officially vetted voice AI architecture specialist.
Proven Track Record: 27+ successful deployments, including single enterprise contracts valued at $9,100+.
Engineering-First Guarantee: Every build comes fully documented with built-in error monitoring and fail-safes.
