I build reliable n8n automation, AI automation, CRM automation, CRM Integrations, Make workflows, Zapier workflows, and API integrations that remove manual work, improve lead follow-up, and keep business systems running without fragile handoffs. I’m a Top Rated Upwork freelancer with 100% Job Success, $80K+ earned, and 130+ completed projects. I help teams connect their CRM, forms, websites, calendars, email, SMS, payment tools, databases, dashboards, and AI tools into one clean automation system. Clients usually hire me when: → Leads are not tracked, assigned, scored, or followed up properly → Their CRM is messy, duplicated, slow, or difficult for the team to use → Forms, websites, ads, calendars, email, SMS, payments, and CRM tools are disconnected → Existing Zapier, Make, or n8n workflows are breaking with real users and real data → They need AI agents, OpenAI, ChatGPT, Claude, API integrations, dashboards, portals, or custom backend logic → No-code tools are not enough and the workflow needs custom development I can help with: → n8n automation workflows, including triggers, webhooks, routers, API calls, conditions, error handling, logs, retries, and n8n cloud or self-hosted setup → AI automation and AI-powered business workflows using OpenAI, ChatGPT, Claude, prompt chains, AI agents, lead qualification, document processing, reporting, and human approval flows → CRM automation, CRM integration, CRM cleanup, pipeline automation, lead routing, lead scoring, sales follow-up, task creation, and reporting → Make scenarios and Zapier workflows with filters, paths, routers, lookup tables, webhooks, custom API requests, and workflow debugging → API integrations using REST APIs, webhooks, OAuth, Google Apps Script, Python scripts, Node JS backend logic, custom scripts, and database sync → Automated lead capture, routing, scoring, assignment, reminders, follow-up, reporting, invoicing, and document generation → Internal dashboards, admin panels, client portals, SaaS tools, and custom business applications when automation tools are not enough CRM platforms I work with include: HubSpot, GoHighLevel, Pipedrive, Salesforce, Zoho CRM, Monday, Airtable, ClickUp, Keap, Freshsales, ActiveCampaign, Mailchimp, Klaviyo, Insightly, Copper, and custom CRM systems. Automation and integration tools I use include: n8n, Make, Zapier, OpenAI, Claude, ChatGPT, Google Apps Script, Airtable, Notion, Google Sheets, Slack, Trello, Asana, ClickUp, APIs, webhooks, custom Python scripts, and Node JS backend logic. Full-stack and backend tools I work with include: React, Node JS, Python, Django, Flask, FastAPI, Express, MongoDB, PostgreSQL, MySQL, REST APIs, admin panels, dashboards, portals, and custom web apps. Before building, I map the full workflow: → Where the data starts → Where it needs to go → What should happen automatically → What should stay manual → What can fail → How duplicates should be handled → How errors should be logged, retried, or reported → How the team will use the system after delivery This helps avoid fragile automations, duplicate CRM records, broken webhooks, messy dashboards, missing follow-ups, and expensive rebuilds later. The goal is not just to connect apps together. The goal is to build a clean, reliable automation system that saves time, reduces errors, improves response speed, and gives your team a process they can actually use after delivery. Message me with your current tools, workflow, and the main bottleneck. I’ll suggest the cleanest way to build it using n8n, AI automation, CRM integration, Make, Zapier, APIs, or custom development when needed.
