Senior Systems Engineer HeadQuarters LLC
I architected and deployed a multi-tenant financial SaaS platform using Django, Django REST Framework, Angular, PostgreSQL, Docker, and Nginx. The platform integrated QuickBooks Online through a custom gateway and delivered accounts receivable/payable visibility, aging analytics, cash forecasting, and cash planning for multiple clients and entities.
I designed a Google Cloud data platform using BigQuery, Airflow, n8n, FastAPI, and Google Apps Script for ingestion, transformation, validation, and reporting across financial, operational, workforce, and client systems. I also built an AI-powered AP document-processing solution with OCR extraction, accounting validation, QuickBooks reconciliation, human review, idempotency, retries, auditability, CI/CD, monitoring, OAuth2, and event-driven integrations.
