Hi! I'm Tetiana - an AI Automation Expert who helps businesses eliminate manual work and build systems that run reliably on their own. If you need someone who delivers working automations in production - not just polished demos - you are in the right place. I design and build integrations using Make (Integromat), N8N, and Zapier - connecting tools, syncing data, and turning repetitive processes into fully automated workflows. Beyond that, I build AI Agents and AI workflows inside Make and N8N using LLM integrations (OpenAI, Claude), RAG pipelines, and MCP tools - so your systems do not just move data, they reason and act. For CRM, I cover both directions: I set up and configure HubSpot, Pipedrive, and GoHighLevel - building pipelines, automations, and workflows inside the platform. When clients need something more tailored, I build custom CRM systems in Airtable - with relational databases, role-based access, interfaces, and automations - then connect everything to external tools via Make, N8N, or Zapier. What sets my work apart: every system includes error handling, data validation, retries, fallbacks, and full documentation - built to run long-term without constant fixes. 🚀 What I help with Integrations with Make, N8N, and Zapier I build multi-step workflows, API connections, data routing, filtering, two-way syncs, and real-time tracking. I also fix and optimize existing Make and N8N automations that are broken or hard to scale. Need to migrate from Zapier to N8N or Make? I handle that too. AI Agents and AI Automation I build custom AI Agents inside Make and N8N using OpenAI, Claude, and other LLM integrations - including RAG pipelines, MCP tools, Agentic AI workflows, AI email assistants, and AI content generation systems. I also build AI image generation and AI video generation pipelines for content teams. AI Automation is the core of every system I deliver - not a feature added on top. CRM Setup and CRM Automation I configure HubSpot CRM, Pipedrive CRM, and GoHighLevel CRM - pipelines, lead scoring, follow-up sequences, task automation, and reporting. Then I connect these platforms to your other tools via Make, N8N, or Zapier for end-to-end CRM Automation that means fewer manual steps, cleaner data, and faster follow-ups. Custom Airtable CRM Builds When standard CRMs do not fit, I build custom systems in Airtable - relational tables, Airtable interfaces, Airtable Softr portals, role-based permissions, and Airtable inventory management - connected to third-party apps via Make or N8N. 📌 How I work 1. Discovery - your tools, your exact outcome 2. Process map with edge cases and clear ownership 3. Build and test with retries, fallbacks, logging, and alerts 4. Documentation and handover so your team can maintain it 🛠️ Tools I work with Automation: Make (Integromat), N8N, Zapier - make automation scenarios, N8N workflows, N8N Supabase, N8N RAG pipelines AI: OpenAI (ChatGPT), Claude, RAG pipelines, MCP tools, Agentic AI, AI image generation, AI video generation, HeyGen, Bannerbird CRM: HubSpot CRM, Pipedrive CRM, GoHighLevel CRM, Airtable CRM, Airtable database, Airtable Interface, Softr Forms: Typeform, Jotform, Google Forms, Gravity Forms Payments: Stripe, QuickBooks Online, Xero, Monobank Scheduling: Calendly, Google Calendar, Slack, WhatsApp E-commerce and docs: Shopify, PandaDoc Tracking: Meta Ads, Facebook Ads API, Google Ads, Google Analytics APIs: Webhooks, REST API, Google Apps Script If you have a process that still runs manually - or an automation that keeps breaking - send me a message. I will take a look and tell you exactly how to fix it.
