You will get an API, CRM and Google Sheets integration for your workflow
Project details
I will build a practical integration that connects your API, CRM, Google Sheets, or webhook-based tools so your business data moves cleanly between systems. The goal is not just to connect apps, but to create a workflow you can actually use: clear field mapping, basic validation, error handling where needed, and simple documentation for your team. This project is a good fit for lead capture, CRM updates, reporting sheets, alerts, and small operational workflows. I bring 19+ years of software development experience with APIs, databases, CRM systems, webhooks, and business automation, so I can understand both the technical side and the real business process behind it.

About David
n8n Automation Developer | AI Workflows, APIs, CRM & WhatsApp
Cartago, Costa Rica - 10:52 pm local time
I am a Senior Full Stack Developer with 19+ years of experience in .NET, C#, SQL Server, CRM platforms, webhooks, API integrations, omnichannel systems, and business process automation. My focus is practical automation: workflows that reduce manual work, connect tools, capture leads, improve customer service, and make business processes easier to manage.
I can help with:
- n8n workflow automation
- API and webhook integrations
- CRM, lead capture, and sales process automation
- WhatsApp Business and chatbot workflows
- Google Sheets, Google Calendar, Supabase, SQL Server, and database integrations
- AI-assisted processes using OpenAI, Claude, and structured prompts
My background in enterprise systems, CRM, SQL Server, SSIS, and omnichannel messaging helps me build automations that are not only functional, but maintainable and clear for non-technical teams.
If you need a small automation, a first MVP, or ongoing support for business workflows, I can help you define the scope, build the solution, test it, and document how to use it.
