Developed end-to-end research pipelines, from problem framing and data acquisition/cleaning to feature engineering, model training, and rigorous evaluation, building modular dataloaders/metrics and automating experiments on HPC/SLURM.
Structured reproducible experiments with clear baselines, ablations, and uncertainty/error analyses; maintained versioned configurations, and comprehensive run logs to ensure consistency in model training and evaluation.
Implemented research-grade engineering practices including unit testing, code reviews, and lightweight MLOps work- flows for artifact management, leveraging platforms that parallel cloud-based ML infrastructure
Collaborated with faculty and peers to refine hypotheses and prioritize experiments; distilled findings into manuscripts, slides, and posters, and managed revisions/responded to reviews on tight timelines.
Ensured responsible data practices and thorough documentation of dataset preprocessing and labeling, contributing to scalable data pipeline standards.
Analyzed phishing email patterns that bypassed firewalls, applying data-driven strategies to develop detection methods and support actionable insights for the Global Information Security team.
Presented analytical findings and proposed detection methodologies to internal stakeholders, enhancing security measures through detailed reporting and collaborative feedback.
Designed and shipped Java/Spring features including PayPal integration, auto-recharge, email automation, ensuring re- liable software deployments
Built VoIP prob-based SIMBox fraud detection pipeline to flag illegal gateways and numbers, with automated scheduled reports.
Captured OTT traffic (Viber/WhatsApp/Skype/IMO) with Wireshark; engineered statistical features and trained machine learning models to detect call packets, achieving 78% accuracy for Viber call-hijacking detection.
Reverse engineered OTT apps using DEX2Jar, JD-GUI, and APKTool; decrypted SIP channels, and analyzed their encryption patterns with WireShark; documented ECDH/ECDHE and full key-exchange flows; recommended security enhancements.
