Cloud Architecture

Two production-style AWS builds: one focused on fault tolerance under load, the other on independent deployability and cost efficiency.

CloudAWS
Fault-Tolerant AWS Admissions Architecture
Designed and deployed a fault-tolerant architecture for a university admissions application across two Availability Zones. EC2 instances run in private subnets behind an Application Load Balancer, with Auto Scaling validated to four instances under simulated peak traffic and Amazon RDS Multi-AZ synchronous replication providing database high availability.

Pipeline Risk Modeling Platforms (Oil & Gas)
Directed multimillion-dollar, AWS-hosted SaaS implementations supporting probability-based risk modeling across transmission, distribution, and storage pipeline assets for major U.S. pipeline operators. Led cross-functional squads of 8 through requirements, UAT, and production deployment in full compliance with PHMSA, the federal framework governing U.S. hazardous liquid and gas pipeline operations.

Simulated Attack Chain Case Studies

Three simulated AWS attack chains: privilege escalation via Lambda, privilege escalation via EC2 instance profiles, and a full SSRF to breach simulation modeled on the 2019 Capital One incident. The common thread is dangerous permission combinations, not single misconfigurations, being what actually gets exploited.

IAMLambda
Privilege Escalation via Lambda
Starting from a read-only IAM user, chained sts:AssumeRole, Lambda management permissions, and iam:PassRole to reach an overprivileged Lambda execution role. Deployed a payload that attached AdministratorAccess to the original low-privilege user, fully escalating access.

IAMEC2
Privilege Escalation by Attachment
Exploited a combination of iam:PassRole, ec2:RunInstances, and iam:AddRoleToInstanceProfile to swap a low-privilege role for an admin role on an EC2 instance profile. Stole temporary administrator credentials from the Instance Metadata Service and used them to terminate a protected EC2 instance, proving real impact.

Secure Portal & Authentication Enhancements
Implemented Multi-Factor Authentication and Single Sign-On across enterprise portals, and led the integration of a secure payment API with CIBC, one of Canada's largest Schedule I chartered banks, enabling students to transact directly within institutional platforms. Production security work, not a simulated environment.

Applied Agentic AI Case Studies

AgentsMulti-Model
AI Agent Enhancement Project
Expanded an existing AI agent from a basic prototype into a more product-oriented application. Added multi-model testing across OpenAI and Claude to compare response quality, performance, and operating cost, and scoped a usage dashboard covering token consumption, latency, and estimated spend.

MLXGBoost
Imbalanced-Data Fraud Detection
Built a machine learning pipeline for credit card fraud detection on a highly imbalanced dataset, where fraud represented roughly 0.17% of transactions. Compared logistic regression and XGBoost across multiple imbalance-handling techniques, with threshold tuning on the precision-recall curve delivering the strongest practical tradeoff between catching fraud and limiting false alerts.
