I build end-to-end systems — from mobile interfaces to serverless backends and cloud infrastructure.
My work lives at the intersection of mobile development, event-driven architecture, and AWS cloud services. I care deeply about system design, code maintainability, and making technical decisions that scale.
Evolving toward backend architecture, distributed systems, and cloud infrastructure.

Event-driven location system built on AWS
A serverless, event-driven system that tracks user location in real time and triggers automated actions based on geofence boundary events (ENTER / EXIT).
How it works:
- Mobile app (React Native) sends user position via REST API every 100m or every minute — including background mode
- AWS Location Service evaluates whether the user is inside or outside a defined geofence
- EventBridge receives the boundary event and routes it to independent Lambda consumers
- Each consumer handles a separate concern: IoT scene execution, push notifications, and event logging
- Loosely coupled architecture — new consumers can be added without modifying existing services
- Infrastructure fully provisioned with Terraform Why EventBridge? Direct Lambda-to-Lambda calls would tightly couple the location processor to every downstream service. EventBridge decouples producers from consumers, making the system easier to extend and maintain independently.
