Diego Del RÍo GarcÍa

I’m a software engineer specializing in data integrity, billing systems, and data validation, and I bring “15+ years of high-stakes auditing and legal reconnaissance” to engineering problems. I build Python tools where traceability and determinism are non-negotiable, treating a missing log entry as “an unacceptable gap in the audit trail.”

I’m strongest at isolating critical information from high-noise environments and translating audit requirements into testable, reliable systems. My approach centers on reliability patterns like the Transactional Outbox, idempotent webhook ingestion, Dead-Letter Queue design, and dual-write race condition prevention, backed by ACID compliance and audit-ready logging.

In practice, I’ve delivered systems and PoCs such as The Mintlify Sentinel (semantic OpenAPI diffing with an Audit Gate), Micro-Billing-Ledger PoC (FastAPI + SQLite WAL with Dead-Letter Queue reason codes), and Aequitas (privacy auditing & sanitization with bounded backpressure and crash/restart acceptance testing). I also work with real-time auditing and protocol compliance as a Medical Interpreter, and I lead complex stakeholder audits across real estate and logistics—so I bring an evidence-first mindset to every engineering decision.
