Systems Integration Lead

💡 About Me

I am an IT professional with over 15 years of experience specializing in end-to-end data pipelines, ETL orchestration, cloud infrastructure, and custom software development. Holding a Bachelor’s degree in Computer Science, my career has been defined by a passion for transforming complex, siloed data into real-time, production-grade business intelligence.

I bridge the gap between legacy enterprise systems (such as SAP S/4HANA) and modern cloud ecosystems (Google Cloud Platform and Microsoft Azure). Whether designing high-throughput API integrations, automating financial ledger synchronizations, or building secure, custom Python SDKs for internal automation, I focus on building robust architecture that scales.

🚀 Featured Architectural Solutions

Real-Time Financial Data Synchronization

The Challenge: Transition core General Ledger data from legacy hourly batch loads to a sub-second, real-time synchronization framework.

The Solution: Designed and implemented a streaming data pipeline bridging SAP S/4HANA and Google BigQuery. This strategy minimized data latency, giving corporate stakeholders instantaneous visibility into global financial reporting.

Automated Intelligent Invoice Processing

The Challenge: Eliminate manual data entry and optimize high-volume document ingestion.

The Solution: Built an end-to-end automated processing pipeline utilizing Google Document AI for machine-learning-driven optical character recognition (OCR), integrated via Microsoft Graph API to ingest attachments directly from secure communication channels, and streamed structured outputs directly into BigQuery for automated reporting.

Enterprise ERP & Credit Integration

The Challenge: Provide authorized corporate customers with automated, frictionless credit access integrated directly into the company's central records.

The Solution: Spearheaded the integration between Highnote’s credit card issuing platform and our core ERP system, developing complex account synchronization logic to ensure strict ledger accuracy, real-time balance tracking, and authorized tokenization.

🎯 Professional Philosophy

I believe that great software is built on predictability, clean code design, and strict data integrity. When I am not optimizing enterprise infrastructure or refining automation workflows, I enjoy diving into the systems logic found in classic science fiction or exploring the creative constraints of photography.
