Context
The environment
Security testing engagements required both automated coverage and manual reasoning across applications, APIs, authentication flows, and implementation details.
Problem
What needed to change
Identify exploitable weaknesses with enough evidence for engineering teams to reproduce, prioritize, and remediate them without disclosing client-sensitive information.
Constraints
- Client identities, targets, payloads, and findings remain confidential.
- Automated output required manual validation before reporting.
- Evidence needed to be useful to both security and development stakeholders.
Contribution
My responsibility
- Web and mobile penetration testing
- Manual validation of automated findings
- Authentication, API, and configuration testing
- Source-code analysis
- Technical reporting and remediation guidance
Approach
How I structured the work
Map the attack surface
Identify exposed functionality, trust boundaries, authentication paths, and high-risk input points before testing individual controls.
Validate, do not just scan
Combine tooling with manual verification to separate exploitable issues from noise and capture defensible evidence.
Report for remediation
Describe impact, affected behavior, evidence, and practical fixes so findings can move from a security report into engineering work.
Evidence
A safe view of the system
Outcome
What the work established
- Delivered validated findings rather than unreviewed scanner output.
- Produced technical remediation reports for web and mobile application weaknesses.
- Strengthened the connection between adversarial testing and secure development practice.
