Overview
GateShield is a backend-focused security project designed to inspect and classify API traffic before forwarding requests upstream.
The challenge
I wanted to build something that demonstrated backend systems thinking, security awareness, and product framing beyond a standard CRUD application.
What I built
Designed a gateway layer that evaluates requests before forwarding them.
Built rule-based inspection logic for suspicious or risky inputs.
Logged security-relevant events for later analysis.
Structured the app to support future expansion into dashboards, rules management, and richer traffic analysis.
Outcomes
Created a strong security-focused portfolio project aligned with backend and infrastructure roles.
Demonstrated API design, request handling, inspection logic, and architecture planning.
Established a base that can grow into a more production-style security platform.
