Service

API & Integration Development

I build APIs and integration services that connect business applications, automate repetitive processes, and support dependable information exchange between systems.

What This Service Includes

• RESTful API development: Build ASP.NET Core endpoints, backend logic, authentication, authorization, and consistent response contracts.
• Third-party integrations: Connect business software with external providers, SaaS platforms, and cloud APIs.
• ERP and workflow integration: Synchronize data and automate workflows involving time tracking, payroll-related operations, and administrative processes.
• Communication gateways: Implement cloud-backed email, SMS, and notification APIs for application-to-application use.
• Data exchange: Integrate SQL databases and external systems with validation, transformation, and resilient error handling.
• Documentation and testing: Make services easier to integrate, troubleshoot, and maintain through clear contracts and suitable tests.

Relevant Experience

I built serverless email and SMS RESTful gateways using Microsoft Azure, SendGrid, and Twilio. I integrated software with the Fortnox API to automate time tracking and streamline payroll processing, and modernized a Visma Administration 2000 integration agent to improve reliability and communication security.

My Approach

I first identify the systems, their data contracts, business rules, and failure conditions. I then build integrations with clear boundaries, secure communication, predictable error handling, and maintainable code.

Let's Work Together

Whether you need a custom API, ERP integration, or workflow automation, I can help connect the systems your business relies on.
