About Vivek Mayekar

I lead end‑to‑end SAP solution design and delivery across implementations, migrations, and global rollouts. My focus areas include Clean Core extensibility (RAP, in‑app, BTP), ABAP on HANA performance engineering (CDS/AMDP/code pushdown), and secure, scalable integrations (OData/CPI/API‑first). With a background in Computer Engineering and SAP certification, I merge technical depth with strategic vision to drive digital innovation and organizational success.HighlightsBuilt CDS Views for transactional/analytical reporting; enabled Fiori/UI5 and API consumption via OData V2/V4.Designed RAP‑based apps to modernize UX and protect Clean Core, standardizing behaviors, service bindings, and annotations.Achieved ~80% faster execution for complex reports using AMDP/SQLScript, CDS refactoring, and parallelization.Delivered multi‑country CFIN rollouts, ensuring robust replication, reconciliation, and mapping (IDocs, AIF, SLT); custom WBS mapping improved accuracy and reduced reconciliation delays.Strengthened MDG workflows, built custom loaders/templates, and improved data quality and cutover readiness.Automated Treasury (FX/FTP) valuation and cash flow postings, reducing manual effort and improving visibility and auditability.Led integration architecture with SAP CPI and third‑party platforms; delivered secure, versioned APIs with throttling, retries, and observability.Established quality governance (ATC/SCI, ABAP Unit, peer reviews), DevOps practices (gCTS/Git), and Cloud ALM‑based delivery.Advocated Clean Core guardrails, guiding extension decisions to maintain upgradeability.Mentored teams, drove code reuse/patterns, and improved velocity and maintainability across releases.SkillsTechnical: ABAP OO, RAP, AMDP/SQLScript, CDS, OData V2/V4, Fiori/UI5, CPI, REST/SOAP, RFC, AIF, SLT, MDG, Migration Cockpit, BTP, ABAP Unit, ATC/SCI, gCTS/Git, SAP Cloud ALM.Domains: FI/CO (strong CFIN), Treasury (FX/FTP), MM/SD/PP/PM/PS/QM/EWM, Analytics/BW, Governance & Compliance.My ApproachAt my organization, we thrive on pioneering SAP solutions.
