You will get Advanced n8n Automation Workflows (APIs, Validation, Logging, CRM Sync)
Top Rated
Project details
You will get a complete, production-ready automation workflow built in n8n or Make.com — including API integration, validation logic, clean routing, structured logging, and clear documentation.
I design workflows that are reliable, scalable, and easy to maintain, ideal for data pipelines, lead flows, CRM sync, reporting systems, and multi-API orchestration.
My expertise includes:
• n8n workflow development (branching, retries, error-proof routes)
• REST API integration (auth, GET/POST, pagination, schema checks)
• Multi-stage validation (email, numeric, rules)
• Webhooks, triggers, event processing
• Google Sheets / Airtable automation
• Logging, error handling, Slack/email alerts
Every project includes a clean build, structured notes, and a stable system you can expand later. Whether you need a simple API trigger or a full intake-to-CRM automation pipeline, I deliver a workflow that works smoothly from end to end.

Senior n8n Automation Engineer for Complex API + Airtable + AI Workflow
Working with Lanh was a genuinely great experience. Communication was clear, fast and professional throughout the entire process. What stood out most was the ability to understand complex requirements very quickly and translate them into clean, thoughtful execution without unnecessary back and forth.
Reliable, detail oriented and highly capable when it comes to technical implementation and structured problem solving. You can tell there is real care behind the work, not just task completion.
Would absolutely work together again and can highly recommend Lanh to anyone looking for someone dependable and skilled.

Lead Qualification & Routing System
Lanh did great work on this project. His documentation was clear, his testing was thorough, and he handled edge cases. Would recommend.

Most automation problems I solve are not just about connecting apps. They are about duplicate records, unclear source of truth, wrong create-vs-update logic, silent failures, weak error handling, and AI outputs entering the system without validation.
Core stack: n8n, Make, Zapier, Airtable, Google Sheets, APIs/webhooks, Google Workspace, OpenAI/Claude, and CRM-style workflow systems.
Common systems I build:
- n8n/API/AI workflows with validation, logs, and controlled AI outputs
- CRM lead intake, qualification, routing, follow-up, and pipeline updates
- Make/Zapier automations for sales, operations, reporting, and handoff
- Airtable/Google Sheets source-of-truth systems with create-vs-update logic
- OCR/document/invoice processing workflows with exception handling
- Workflow audits, debugging, stabilization, and SOP handoff
Relevant systems I’ve built:
- n8n + Airtable + AI/API workflow with validation gates, safe update rules, testing checkpoints, and error handling
- OCR/document processing pipeline using Gmail/Drive intake, OCR/AI extraction, normalized fields, client-based routing, logs, and failure paths
- Lead qualification and routing system with form intake, deduplication, AI/rule-based scoring, create-vs-update logic, team notifications, and structured logs
- Financial/data automation workflows with deterministic matching, confidence scoring, anomaly flags, audit logs, and review states
How I work:
1. Understand the business process and expected outcome
2. Map the data flow, source of truth, and ownership rules
3. Build the workflow with validation and clear status logic
4. Test real scenarios, edge cases, duplicates, and failure paths
5. Document the system so your team can operate and maintain it
Best fit:
- Founders and lean teams with messy operational workflows
- Agencies managing leads, reporting, client operations, or internal handoffs
- Businesses using Airtable, Google Sheets, Notion, forms, CRMs, APIs, n8n, Make, or Zapier
- Teams that need reliable automation with clear logs, ownership, and maintainable handoff
If you have a workflow in mind, I can help map the logic, identify the failure points, and define the cleanest way to build it.
Steps for completing your project
After purchasing the project, send requirements so Lanh can start the project.
Delivery time starts when Lanh receives requirements from you.
Lanh works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements & workflow understanding
You submit your answers to the project requirements. I review your workflow needs, apps involved, and expected output.
Workflow design & mapping
I outline the automation flow (triggers → logic → API steps → output). Standard & Advanced tiers include a mini architecture diagram.
