Abdullah M.

I'm Abdullah Mahmoud, a Senior Support and Implementation Engineer with hands-on experience in electronic payment systems, software testing, technical troubleshooting, and application support.

I help businesses verify software functionality, identify issues, and document findings clearly so development teams can reproduce and resolve them efficiently.

My services include:

• Manual testing of applications and systems against business requirements.

• User Acceptance Testing (UAT) and verification of fixes and new releases.

• Bug reports with reproduction steps, expected and actual results, and supporting evidence.

• API testing using Postman.

• Application log analysis and technical troubleshooting.

• SQL queries for data validation and investigation.

• POS application and terminal configuration, deployment, and support.

• Preparation of test reports, operating procedures, and technical documentation.

My background in payment operations and implementation helps me understand how technical issues affect users and daily business processes.

I focus on understanding your requirements, maintaining clear communication, and delivering practical, well-documented results.
