ASP.NET Core, Entity Framework Core, and C# Backend Development
Currently studying architecture patterns, clean APIs, and scalable .NET backend design.
A practical approach to complex systems.
I build and maintain backend systems for ecommerce operations, with hands-on experience in Adobe Commerce, Magento, APIs, data synchronization and production support.
My earlier career in civil engineering shaped a practical systems mindset: understand the constraints, make the dependencies visible, and deliver something teams can operate with confidence.

How I work
Every integration follows the same path, from the first question to life in production.
Understand
Map the business flow first: which system owns each piece of data, who depends on it, and what breaks when it is late.
→ flow map & owners
Design
Agree on payloads, boundaries and error handling before writing code, so every system knows what to expect.
→ contracts & failure modes
Build
Ship Magento modules, endpoints and integration jobs in small, reviewable steps, checked against realistic data.
→ modules, APIs & sync jobs
Operate
Stay with it after go-live: watch the logs, support the team and keep the system healthy as the business changes.
→ logs, fixes & upkeep
