At SEIDOR, I deliver SAP S/4HANA implementations and custom development projects for more than 10 clients across oil and gas, construction, finance, and retail.
I build ABAP Cloud solutions with RAP, CDS-based OData V4 services, AMDP, HANA calculated views, data cubes, and stored procedures. I also extend SAP processes across SD, MM, PM, and FI through BAdIs and user exits.
I design SAP Integration Suite flows that connect S/4HANA with third-party ERPs, banking platforms, and web services through REST and SOAP. My work includes a mass payment file generator integrating React.js with SAP Business One Service Layer and HANA-based financial aggregation.
I bring full-stack ownership to integration work, building React.js, C#, Python/FastAPI, PostgreSQL, MariaDB, Docker, and Ubuntu Server solutions. Earlier, I developed workforce-management modules at Casa Luis Pazmiño and supported IT infrastructure at PepsiCo Alimentos Ecuador.
