About me

I'm Juan Manuel Vallecillos, SAP consultant and developer. I've spent over 10 years working on implementation, support, and evolutive projects, always at the intersection of ABAP development and Finance (FI) / Materials Management (MM) business processes.

I've worked on projects of every size: full implementations, migrations, AMS support, and one-off developments of high complexity for companies across very different industries (manufacturing, distribution, services). I don't share client names or identifiable project details here, but I do share the technical problems that keep repeating, regardless of the industry.

Besides my work as an independent consultant, I'm also part of my own SAP consulting company, which I turn to for projects that need more hands than I can provide alone.
