Work Experience
Test Engineer
GLI(A · Gauteng, South Africa · April 2025 – Present
- Performed end-to-end functional, regression, integration, and exploratory validation of regulated financial platforms across 15+ international jurisdictions, verifying that system behavior met applicable regulatory and certification requirements at every layer, from user-facing transactions to back-office records. This ensured platforms were certifiably compliant before market entry, directly reducing the risk of regulatory rejection and post-launch remediation costs.
- Validated complex financial calculations including account balances, payouts, refunds, and full transaction lifecycle workflows through functional and transactional testing, comparing results across integrated systems to confirm end-to-end consistency. Achieved 100% accuracy on certification-critical financial calculations, providing regulators and stakeholders with auditable proof of system integrity.
- Executed integration testing across interconnected platform components, including transaction engines, account histories, and back-office reporting systems, verifying that data flowed accurately and consistently between all layers. Identified integration failures and transactional discrepancies before submission, preventing systemic errors from reaching production or regulatory review.
- Proactively identified edge cases, compliance risks, and documentation mismatches in new system builds through exploratory and compliance testing, logging and managing all findings in JIRA with full evidence, expected vs. actual outcomes, screenshots, and supporting records. This strengthened system reliability and reduced the likelihood of regulatory delays or failed certification submissions.
- Reviewed source code changes, build versions, and system behavior to confirm strict alignment with previously certified baselines, ensuring no unauthorized modifications were introduced between approved and submitted builds. This enforced change control discipline and protected the integrity of the certification audit trail.
- Compiled comprehensive test evidence, compliance findings, and certification reports that served as the official basis for regulatory approval and market entry across multiple jurisdictions. Produced documentation to a standard accepted by regulators, directly supporting commercial timelines and license approvals.
- Managed 5+ concurrent regulatory submissions simultaneously, maintaining accuracy, full traceability, and 100% adherence to strict regulatory deadlines across all active work streams. Demonstrated the capacity to operate under regulatory pressure without sacrificing quality or compliance rigor.
