At eSales, I own production support for a supply chain management and integration platform used by shippers and carriers, from incident triage and root-cause analysis through deployment and verification. I hardened APIs without disrupting active integrations, stabilized a UTF-8 migration across system boundaries, and built an automated support deployment pipeline.
I've worked with PHP since 2001 across logistics, education, insurance, healthcare, telecom, and infrastructure. At Paper CO, I helped build an AI tutor for children using the OpenAI API, fine-tuning, system prompts, and guardrails; I also bring deep experience with legacy systems, Oracle PL/SQL, Java, COBOL mainframe integrations, Linux, and production operations.
