Stream Lead - Tata Consultancy Services (TCS) - Switzerland
(2023-01)
- Led a cross-functional team across parallel S/4HANA release cycles (RE2, RE3, RE4 & RE8), managing end-to-end delivery of 60+ migration objects with full ownership of timelines, sprint planning, and cutover execution; engaged onsite with client stakeholders during design, mock load, and production load phases driving alignment through proactive stakeholder management.
- Ensured 100% load rate and data quality across all release deliverables including parallel delta load phases; coordinated Enterprise Asset Management (EAM) Functionals and ABAPers to resolve issues with minimal delay — earning formal client and project stakeholder recognition for closing all migration objects ahead of schedule and go-live support.
- Automated end-to-end migration workflows by bridging BODS staging tables to Migration Cockpit via database synonyms; eliminated a ~10-step LSMW load process through IDoc extension and replaced manual Excel-based value mapping with automated table extraction — reducing load times, eliminating errors, and ensuring zero data loss.
- Acted as technical anchor and first-line support; extracted and reconciled Maximo (non-SAP) data for SAP migration, automating file-based delivery directly into staging tables; resolved 100+ defects during mock data load cycles, led Root Cause Analysis (RCA) sessions to mentor the team, and managed stakeholder communication by translating complex issues into clear, actionable updates.
- Delivered cross-module support including Logistics classification objects and Project Systems (PS) dependency builds; managed end-to-end Transport Request (TR) lifecycle across Development, Integration, and Production landscapes ensuring version-controlled object migrations.
Data Migration Developer - Tata Consultancy Services (TCS) - Switzerland
(2021-12 - 2022-12)
- Designed and executed end-to-end Extract, Transform, Validate, Load & Reconcile (ETVLR) pipelines in SAP BODS sourcing from SAP ECC, Data Collection Files (DCFs), and non-SAP systems; performed data profiling, cleansing, and deduplication to ensure source data integrity prior to migration.
- Defined data quality rules, field mapping specifications, and transformation logic across all migration objects; validated rule adherence at each stage to enforce completeness, consistency, and referential integrity.
- Extracted data from SAP ECC, applied transformation rules, and loaded into SAP S/4HANA via Migration Cockpit (LTMC/LTMOM), LSMW, FM/BAPI, and IDOCs; executed pre-load and post-load validations with reconciliation across record counts, key fields, and financial balances.
- Migrated master and transactional data across Plant Maintenance and Asset Management with end-to-end quality validation and sign-off at each migration phase.
- Built BOBI Web Intelligence reports to automate reconciliation workflows and managed Transport Request (TR) promotions across Dev, QA, and Production landscapes. Implemented multiple automation solutions — auto-generating Migration Cockpit templates, consolidating 300+ Excel tabs, aligning mandatory fields with Data Field Specification (DFS) files, and building a real-time load status tracker — reducing manual effort across the migration lifecycle.
- Proactively took on additional migration objects during mock, cutover, and production load phases within a SAFe Agile delivery framework; supported teammates with error resolution and BOBI report enhancements — consistently exceeding assigned scope.
