Jorge Martinez-Rocha

About

Backend-focused engineer who built a time-sensitive data retrieval system for a source with no public API, using an AWS EC2-hosted persistent browser session plus a PostgreSQL TTL caching layer—cutting manual retrieval by 99% and achieving sub-10-second average retrieval. Emphasizes production security (Secrets Manager, encryption, IP allowlisting, rate limiting) and robustness via testing and edge-case handling (atomic file operations).

Key Strengths

• Designed AWS EC2-based backend with persistent browser + PostgreSQL TTL cache for non-API data source
• Reduced manual data retrieval by 99% with average retrieval time under 10 seconds
• Strong security implementation: Secrets Manager auth keys, encryption, IP-restricted access, CORS, rate limiting
• API reliability practices in Python/FastAPI: async I/O, validation, exception handling
• Test-driven/iterative testing approach that minimized regressions and sped delivery
• Proactively identified failure modes (app close during file processing) and implemented atomic file operations to prevent corruption
• Managed migration from local server to AWS EC2 with risk review and peer/mentor code/security review
