Evan Dubuilds intelligent systems.

Cloud-native API gateway that dynamically reroutes traffic toward healthier and faster service replicas during load spikes.

• Built a MAPE-K control loop with a UCB multi-armed bandit strategy.
• Deployed microservices on IBM OpenShift/Kubernetes.
• Added EMA smoothing, cooldowns, and circuit-breaker safeguards.

Wireless embedded control system that replaced wired GPIO triggering with a Wi-Fi-based trigger path while preserving reliable event timing.

• Designed a lightweight wireless trigger protocol with synchronization.
• Handled packet loss using timeout and retry logic.
• Evaluated jitter, delay, missed triggers, duplicated triggers, and delayed packets.

LLM-assisted travel planner that converts user preferences into structured itineraries with transport, lodging, dining, and activity planning.

• Integrated Google Gemini API to generate structured trip plans.
• Built schema validation to normalize and repair LLM outputs.
