What I'm looking for

I’m seeking a Sr Business Integration Analyst EDI role through its API and database path, where I can apply my experience testing APIs, comparing JSON output against relational data, and working with ERP systems.

At BillGO, I worked on roughly 3,000 biller-site integrations, validating REST API requests and JSON responses against OpenAPI specs and checking results with SQL. I traced a Wells Fargo error to a sitewide account-type change by sampling similar accounts, turning what looked like a one-off issue into a systematic fix.

At Gibraltar Building Products, I process vendor invoices and payments in SAP and Syspro, including 3-way matching. I bring nearly a decade of accounting and AP experience, alongside a B.S. in Business Administration (Accountancy).

I’ve kept building software through projects such as ap-invoice-tracker, a FastAPI and Pydantic REST API for AP invoices and vendors with MySQL-backed 3-way match endpoints. At Coding Dojo, I taught web development and received a 9.6/10 average in student feedback.
