About this gig

Scale your business with Enterprise-Grade Engineering.


Are you looking to bridge the gap between your CRM and your operational data? As a Systems Engineer, I specialize in building robust integrations and custom software that traditional "coders" often overlook.


My Expertise Includes:

  • Microsoft Dynamics 365: Custom API integrations, Power Platform automation, and data synchronization.
  • .NET & C# Development: Building scalable, secure backends and desktop applications.
  • Third-Party Bridges: Connecting Dynamics 365 with platforms like WhatsApp, Twilio, or custom SQL databases.
  • Containerization: Ready-to-deploy solutions using Docker for maximum reliability.


Why work with me? Unlike generalists, I understand the underlying architecture of enterprise systems. My code is clean, documented in English, and built to handle high-concurrency environments.

Please message me before placing an order to discuss your specific technical requirements.
