Acerca de este Servicio
Businesses lose money every day their systems don't talk to each other manual data entry, missed orders, disconnected customer records. I fix that.
I'm a Senior Integration Lead with 7+ years building production integrations for enterprise SaaS platforms in the .NET/C# ecosystem. I've connected CRMs, ERPs, payment gateways, and internal tools for companies that can't afford broken data pipelines.
What you get:
- Clean, documented, production-grade code (not a duct-taped script)
- Proper error handling and retry logic integrations that don't silently fail
- Data mapping between systems with different schemas
- Security best practices (OAuth2, API key rotation, encrypted secrets)
I only take on integration work I can guarantee is stable. If your stack is unusual, message me before ordering I'll tell you honestly whether I'm the right fit.
