Silvershield
Software Engineer • Jul 2023–Nov 2024
Silvershield is a full-stack AI-enabled fraud monitoring platform that helps families protect senior relatives from inbox scams. I built the platform from concept to beta, owning all architecture and technology decisions end-to-end — selecting the stack, designing the data model, and shipping every feature.

Infrastructure & Security
With users trusting the platform with access to sensitive email inboxes, security and data integrity were the primary design constraints. I architected auth, permissions, and data access using Supabase Row Level Security and JWTs across a multi-user, multi-organization structure — ensuring each user could only access exactly the data they were permitted to see.
Performance & Cost
The original architecture used Nylas to connect Gmail inboxes for fraud detection. After profiling the system I identified it as both a cost and performance bottleneck and replaced it with a direct GCP integration. The result was a 70% reduction in infrastructure cost and a 90% improvement in processing speed.
