Business Analytics Sprint

Data Science · October 2026

88/ 100

A ProoV case study · educational project, not employment

Built an end-to-end profit investigation that framed hypotheses, audited the data, and answered two SQL questions with correct aggregation and join logic. Identified Mobility as the largest category and Asia Pacific as the weakest-margin region, then translated those findings into a prioritized recovery plan, boardroom deck, stakeholder Q&A, and executive summary focused on discount governance and logistics efficiency.

Fundamentals of Cybersecurity

Cybersecurity · October 2026

84/ 100

A ProoV case study · educational project, not employment

Built a complete beginner SOC incident response workflow for a phishing-led breach: triaged the email indicators, mapped the attack to kill-chain stages, identified the anomalous sign-in, extracted the relevant IoCs, and sequenced containment actions that cut access first. Also drafted a GDPR Article 33 notification and an executive incident summary grounded in timestamps, scope, and response actions.

What stood out6

Correctly identified all four phishing red flags and reached the malicious verdict
Flagged the impossible-travel sign-in row and tied it to the intrusion path
Ordered containment actions sensibly by cutting access first before broader remediation
Anchored the response to concrete incident facts such as the 72-hour GDPR clock and the Rotterdam login
Leakage-Free Incident Triage
Evidence-Based Log Investigation

AI-Assisted Code Modernization with IBM

Junior Software Engineer · Software Engineering · October 2026

96/ 100

Based on a public IBM case study · not affiliated with IBM

Built and verified a full legacy-code modernization for a fleet maintenance service: fixed the wear calculation so nearly-due cars are flagged, handled missing service readings safely, corrected the nightly report’s average and crash path, and repaired a hidden mileage-conversion bug in shared helpers. Also added a data-driven breakdown-risk analysis that prioritizes active usage signals over total mileage, and documented the review process in NOTES.md.
