About Espe

I help companies save time and reduce errors by automating processes, integrating APIs, and developing custom .NET tools.

I specialize in environments with repetitive manual tasks, data exchange between systems, and the need for more efficient reporting or process management.

I have experience in:
•Internal process automation
•API integration (REST and SOAP)
•Automatic report generation
•VB.NET / .NET development
•Electronic invoicing (FACE and eFACT)
•Energy sector

I have worked in real-world scenarios where technology must provide practical, reliable, and maintainable solutions.

My approach is clear: understand the problem, simplify the process, and develop solutions that genuinely improve daily operations.

Outside of the technical realm, I am inspired by music, animals, and the mountains, three aspects that reflect my work style: perseverance, attention to detail, and balance.
