@fabianvelasquez
I test security-sensitive SaaS products, protecting tenant data, evidence integrity, and release quality.
ColombiaWhat I'm looking for
At EPAM Systems for Cellebrite, I've tested Guardian Pro, Guardian NG, and Guardian Forensics—digital-forensics SaaS products handling evidence ingestion, hashing, permissions, auditing, and reporting. I've documented over 500 defects, with 302 confirmed Engineering fixes, and validated releases and UAT across the US, UK, Brazil, and Australia.
I focus on manual functional and risk-based testing for multi-tenant RBAC, customer-data separation, MD5/SHA256 evidence hashes, audit logs, APIs, and negative paths. Before Cellebrite, I spent more than seven years testing telecom IVR and MVNO flows at Quantica BPO, including activations, number porting, service purchases, and account refills.
