What I'm looking for

I’m looking for backend-focused opportunities in SaaS, ERP, fintech, business platforms, and data-intensive products.

At TTMI, I co-lead backend delivery for a 20-module ERP platform supporting accounting and store-management users across 50 stores. I designed and implemented a weighted-average inventory costing engine with accountants, translating business rules into transaction-safe inventory and accounting workflows.

I re-engineered bulk invoice ingestion with PostgreSQL COPY and staged processing, reducing an estimated three-hour batch to 15 minutes. I also designed resilient AWS SQS/ECS background processing and optimized financial and inventory reporting.

Previously, at Locuno - Family Safety Network, I designed and implemented a Django REST backend for an HRM and KPI evaluation platform, including role-based access, approval workflows, and asynchronous report generation. I’m open to backend-focused opportunities in SaaS, ERP, fintech, business platforms, and data-intensive products.
