About
At InsightPRO, I validate Call Detail Record data across two billing systems for National Telecom Public Company Limited. I developed Python scripts with Antigravity and Codex to check high-volume data across Excel, CSV, and status reports.
I use Postman to provision test data and validate APIs, and Apache JMeter to evaluate performance and system stability. I also investigate duplicate and suspense records, track defects through resolution, and document QA results.
Previously, I tested telecom, POS, web, and mobile applications at YIP IN TSOI & CO., LTD., K. Stone Corporation Co., Ltd., Gosoft (Thailand) Co., Ltd., and 1 MOBY CO., LTD. My work included designing and executing test cases, supporting SIT and UAT, and validating payment and promotional workflows.
