Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I’m a full-stack engineer with 13 years of experience shipping end-to-end products—from taking features all the way from embedded/LoRaWAN firmware through AWS pipelines and Elasticsearch to React/Vue dashboards people use every day. I enjoy working remote-first, building systems that are fast, reliable, and easy to maintain across time zones. These days I also cover parts of AI infrastructure for clients and run self-hosted services at home, including model inference and training on hardware I control. I’ve built and owned production IoT platforms (including device ingest through AWS services like IoT Core, Lambda, SQS, and SNS), with full visibility from the sensor and device code up to the UI, dashboards, and authentication layers.…I’m a full-stack engineer with 13 years of experience shipping end-to-end products—from taking features all the way from embedded/LoRaWAN firmware through AWS pipelines and Elasticsearch to React/Vue dashboards people use every day.
