I’m an embedded systems developer and practical problem-solver focused on low-power IoT. I work extensively with ESP32-class hardware, BLE advertising and connection flows, and LoRa/LoRaWAN telemetry for metering and environmental sensing. On the device side I’m comfortable with ESP-IDF/Arduino, sleep-mode optimization, SDI-12 sensor integration, and building usable on-device UIs with LVGL/TFT. On the product side I value clean interfaces and reliable data paths—designing simple provisioning flows, building basic backends and dashboards when needed, and collaborating closely with partners to turn prototypes into field-ready tools. I care about accuracy, battery life, and clarity: systems should be measurable, dependable, and easy to use.

Built and tuned a BLE advertising demo targeting sub-milliamp averages using sleep modes and a 32 kHz external crystal. Focus on measurable current draw, stable intervals, and repeatable test methodology.
Implemented custom frame parsing for volume/flow units and integrated a lightweight telemetry pipeline to visualize usage patterns. Emphasis on robust decoding, retries, and field resilience.
