Where I've worked so far.

Richmond Hill, GA · Contract via Brainer

MES Systems Engineer / DeveloperJan 2026 – Present

Sole onsite MES developer for an EV powertrain plant (inverters, stators, power electronics), covering T-SQL, JSP, and C# WinForms in live production.
Cut worst-case MES downtime from up to 4 hours to under 1 hour per incident (75% reduction) after taking over onsite development and troubleshooting.
Built a material reuse feature in MES so only the main lot counts toward production, with automatic MES-to-ERP reconciliation. Removed manual entry for production teams.
Extended the line tracking display with defect (NG) classification, Cpk threshold alerts, and failure visibility by operation, used daily by quality and production teams.
Built new JSP pages and extended C# WinForms apps that workers use daily to log work orders into MES, and trained production teams on each release.
Handled daily support tickets in Jira and worked with the Korea HQ development team across time zones and languages to fix production issues and MES/ERP data mismatches.

MES System AnalystApr 2025 – Jan 2026

Maintained MES across SQL Server, the application layer, and shop-floor systems. Wrote and tuned T-SQL stored procedures, triggers, and SSMS reports.
Set up SQL Server linked servers so other teams could query MES data across databases without manual exports.
Monitored KepServerEX and OPC channels to keep equipment data flowing into MES, tracing values across OPC, logs, and SQL tables to find root causes.
Checked SQL jobs, backups, and indexes daily and validated the data behind reporting dashboards.
