ESG reporting is a workflow problem as much as a data problem: teams need applicability rules, evidence, consolidation, review, and approvals before a report is ready.

For OriginSustain, I built NestJS/TypeScript backend services, PostgreSQL and Redis/BullMQ processing, and AWS/Docker delivery with CI/CD. OpenAI API and RAG support part of the reporting flow. The screens here are from the product’s illustrative command center; the numbers are demo values, not client outcomes.

You bring the client. I’ll handle the backend.

Opening a few white label slots for agencies, marketers and freelancers who need someone reliable for technical execution.

You keep the client. You keep your branding. I stay behind the scenes.

I can handle:

• Websites • Landing pages • AI automation • n8n workflows • WhatsApp systems • APIs and integrations • Lead generation systems

No need to turn down work because it’s outside your current service stack.

Send me the project, requirements and deadline. We’ll work out the execution and pricing.
