Professional Summary

8+ years of SAP experience spanning seven ERP implementations, custom ABAP/ABAP Objects development, and integration architecture across ECC and S/4HANA. Progressed from functional MM implementation specialist — leading a greenfield ECC deployment and multi-site rollouts — to hands-on ABAP developer and integration architect, building reusable OO frameworks with design patterns (strategy, BAdI, custom exceptions), REST API/webhook connectivity, EDI/IDoc pipelines, and RFC-driven web applications. Full-cycle delivery through requirements gathering, technical design, build, unit testing, integration testing, cutover, and hypercare.

Promotional Trade Management Platform — Flagship Project
Sole developer · live in production 2026 · React 19/Vite SPA + Node.js/Express API · SAP ECC integration via node-rfc · TypeScript · SQL Server · deployed on AKS

• Automates end-to-end retailer trade-deduction clearing — parses retailer deduction files, auto-matches them to SAP trade agreements through a configurable rules engine, and posts to SAP after a multi-role approval workflow, replacing a manual per-deduction clearing process
• Cut weekly deduction-clearing effort ~93% (~57h → ~4h for a typical week), returning an estimated $95k–$135k/yr (~1 FTE; ~2,000–2,700 hours annually) — multi-customer by design and projected to scale to ~$200k/yr across additional retailers
• Runs against a ~$2–3M/week deduction stream with built-in financial safeguards: an append-only exclusion ledger with per-batch reconciliation, duplicate-posting protection, and a minimal SAP write surface of exactly 4 whitelisted write RFCs (never auto-retried)
• Integrated 16 SAP RFC modules (11 custom) via node-rfc; enforced role-based access control with 24 atomic permissions across 5 roles plus a dollar-threshold sign-off gate
• Delivered from request to production go-live in nine weeks — 112 database migrations and 1,600+ automated tests (unit + Playwright E2E), validated against SAP QAS

Implementations & Functional Leadership

• Led a greenfield SAP ECC deployment at a newly acquired subsidiary — full lifecycle from requirements gathering through go-live, replacing legacy Excel operations with a fully integrated ERP environment
• Executed SAP ECC rollouts across multiple production facilities and distribution centers — MM configuration, master data migration, user training, and cutover coordination
• Served as SAP QM module lead for one year — owning inspection plans, quality notifications, and user support across manufacturing sites
• Integrated SAP Ariba for indirect procurement — PunchOut catalog configuration, cXML transaction flows, and supplier onboarding and enablement
• Designed IDoc frameworks for yard inventory visibility and EDI partner integrations (X12 850/855/856/810) via SPS Commerce

Integration Architecture & Custom ABAP Development

• Architected a reusable SAP-DocuSign integration framework in ABAP Objects — OAuth 2.0 authentication, REST API connectivity via ICF handlers, webhook processing, BAdI-based extensibility, and a configurable application registry with optional PI/PO routing
• Automated executive PO approval workflows — release strategy triggers multi-signer DocuSign envelopes with MIGO goods receipt block and BAPI-driven release on final signature
• Built a BSP-based executive approval application — 61-field form with SmartForm PDF generation and a 4-level DocuSign signature chain
• Implemented ABAP Unit test suites covering constants validation, exception handling, error code mapping, and type contracts

Application Development

• Developed an AI-powered process documentation hub (Next.js, Azure AI Search, RAG) and PMO tracking tools for internal operations visibility
• Python automation for master data loading and deployment validation across multi-site SAP landscapes

Independent S/4HANA Development

March 2024 – Present

• Extended SAP-DocuSign integration framework to S/4HANA 2025 using ABAP Objects — strategy pattern (ZIF callback interface with multiple implementations), custom exception classes with HTTP status and error chaining, ICF HTTP webhook handlers; 51+ ABAP objects across 4 transport packages
• Built automated deployment tooling via SAP ADT REST API — Python/Click CLI orchestrating transport package creation, object upload, activation, and cross-system validation across S/4HANA 2025, S/4HANA 2023, and ECC 6.0 environments

NTT DATA Services

SAP Functional Consultant | Business Systems Analysis Senior Associate July 2018 – February 2020 | Phoenix, AZ

• Provided SAP MM help desk support for a major aerospace manufacturer — troubleshooting and break-fix across logistics, sourcing, and quality management modules
• Performed functional configuration maintenance and ticket resolution across the MM landscape
