PPG Industries • Full-time
Jul 2022 - Present • 3 yrs 10 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.
