Selected projects
Work that ships.Proof that holds.
A selection of security and quality engagements - what we tested, what we found, and what changed for the teams that shipped after us.
Case studies
Three engagements. Zero hand-waving.
AI SaaS security and QA hardening
Security testing and QA for an AI content platform on Azure. We assessed the Entra External ID authentication and the Stripe checkout, subscription, and credit-metering flows, verified webhook signature handling and multi-service routing, and reviewed the Azure Container Apps, App Service, PostgreSQL, and Storage Queue footprint - then ran functional and regression passes across the three AI tools before handover.

Multiplayer shogi companion - QA and hardening
Cross-platform QA and infrastructure review for a real-time multiplayer shogi companion built for iPad video production. We tracked down and closed critical coordinate-translation and board-mirroring bugs that broke move sync between players, hardened WebRTC connectivity across PC-to-iPad NAT boundaries with STUN/TURN and timeout handling, and reviewed the AWS Lambda Function URL and cross-region Secrets Manager setup used to issue TURN credentials.
Flowa engagement - Media Production
Workflow automation platform security and QA
Security and QA coverage for an AI-native workflow automation platform built around a drag-and-drop canvas editor, connecting 173+ integration nodes across 23 categories - from AI/ML models and databases to cloud services, social media, and e-commerce. We reviewed credential handling and secrets isolation across third-party connectors, then ran functional and regression testing on the canvas editor and workflow execution engine.
