PROFESSIONAL HISTORY

Career Highlights

CURRENT ROLE

SENIOR DEVELOPER, FRAUD SERVICE LAYER LAB

At Scotiabank's Fraud Service Layer Lab, I'm leading the design and implementation of NRTCHQ — a real-time fraud detection platform processing cheque deposits across Mobile, ATM, and Branch channels. The system identifies suspicious patterns in seconds, preventing fraud at source while maintaining seamless customer experience. I'm driving cross-functional collaboration between fraud analysts, product teams, and infrastructure engineers to translate complex risk requirements into scalable technical solutions.

Key Contributions & Responsibilities

  • NRTCHQ Platform: Designed and led the development of a distributed, real-time fraud detection system processing cheque deposits across three channels (Mobile, ATM, Branch) with sub-second latency—protecting millions of daily transactions from fraud at source.
  • Implemented ML-Driven Risk Assessment: Integrated machine learning models to identify fraudulent cheques instantly, reducing false positives while maintaining high detection accuracy, resulting in faster customer settlement and reduced fraud exposure.
  • Led Cross-Functional Teams: Orchestrated collaboration between fraud analysts, product managers, and infrastructure engineers to translate complex risk requirements into scalable, production-ready technical solutions.

Cisco AppDynamics

2023–2024

SENIOR SOFTWARE ENGINEER & SCRUM MASTER

On the Java Agent Team at Cisco AppDynamics, enhanced an Application Performance Monitoring (APM) product delivered as SaaS—combining software engineering, AI-driven monitoring, and solution design to help global clients optimize performance, reliability, and customer experience.

Key Contributions & Responsibilities

  • AI-powered anomaly detection: Contributed to features that automatically identify abnormal behaviour in business transactions and application metrics—alerting customers proactively before service degradation.
  • Advanced root cause analysis: Built graph-traversal algorithms analyzing slow code execution, database queries, and remote service calls—helping enterprises resolve issues faster.
  • Strengthened SaaS delivery: Partnered with product managers, architects, and vendors to improve delivery models, integration patterns, and enterprise-scale client onboarding.
  • Startup-style innovation: Supported innovation pods piloting AI + SaaS prototypes, later scaled into enterprise-grade offerings.

★ Recognition · "Getting to the Finish Line"

"Thank you for solving problems related to the Analytics agent that helped us secure the SBI account. SBI was reporting issues that weren't reproducing in our environment — you kept chasing the customer until we got access to their environment to reproduce the issue (at very high scale, in a specific setup), which you then resolved. Thank you for your perseverance and customer obsession — this helped us secure the deal with SBI."
