Software Engineer
PPG Industries • Full-time
Jul 2022 - Present • 3 yrs 11 mos
Built and owned a microservices documentation platform (C#, Node.js, Angular) that converts IICS metadata into AI-curated docs via RAG-powered chat using AWS Bedrock and Lambda, serving ~50 engineers across 4 sub-teams on event-driven infrastructure (Kafka, EC2, RDS, S3, Redis, Elasticsearch) with quality gating aligned to ISO/IEC 25010:2023 and IEEE 1012-2016. Developed a 9-page Power BI dashboard (Python, SQL Server, MS Graph API) that ingests and correlates error emails from 15+ legacy servers across the US, Mexico, Europe, and Asia in real time — reducing unplanned downtime by 60%. Also reverse-engineered a Java 8 service from binary alone, rebuilding it as a Spring Boot application with restored serial-port/industrial scale integration, preserved SOA layer, and an async disk queue for zero data loss on network interruption.

Carlos exceeded my expectations on this documentation project. He delivered a complete architecture diagram, visual ERD database schema, API contract documentation with 75+ endpoints, and a phased itemized quote for all 36 steps of our platform. What stood out most was his patience and politeness throughout...

Carlos helped us with technical infrastructure and platform integration work. He was responsive, professional, and willing to investigate issues carefully rather than rushing through the job. He communicated well during the process and worked patiently through the server and configuration challenges...
