Role
Senior Partner Solution Architect, IoT Specialist
-
Highlights
- I worked with many well-known Partners of AWS in the LoRaWAN sensor and gateway industry. I delivered several automated solutions to Partners for migrating fleets of LoRaWAN gateways from other providers (TTN, Chirpstack, etc.) to AWS IoT for LoRaWAN.
- I evaluated Partner hardware for compatibility with AWS IoT and IoT for LoRaWAN.
- I worked with an AWS customer to create a functionally equivalent IoT Core MQTT broker service using AWS Fargate. The solution was needed due to the age of the devices and their inability to perform SNI on TLS connections. I accepted this work due to my interest in solving problems in aging/legacy IoT devices that can be marooned/end-of-lifed due to cost-benefit ratios of replacing vs. supporting older devices. This is a special consideration for older medical devices that many people rely on.
- I evaluated IOTSAFE provisioning workflows and compatibility with IoT Core.
- I created an automated deployment procedure and CDK solution for Kubernetes environments providing High-Availability Greengrass machine vision capabilities.
- I assisted many Partners, colleagues and customers on IoT device provisioning workflows like JITR, JITP, EOST (RFC7030).
- My main super powers while in the AWS Partner organization was providing clear, well drawn architecture and sequence diagrams and delivering CDK/Cloudformation solutions for various AWS IoT automation tasks.
