Embedded IoT engineer with end-to-end experience shipping connected devices and the systems around them. Deep in wireless smart-home firmware (Matter over Thread, Zigbee, BLE, and Wi-Fi on ESP32 and nRF), factory tooling, and OTA. Broad across full-stack web backends, cloud dashboards, and CI/CD. At ReZ-TI I own embedded technical direction—selecting chipsets, wireless stacks, and hardware-software trade-offs—while building the build-provision-flash toolchain that runs our manufacturing line.
Experience
Lead embedded technical execution for Matter-compliant smart home devices. Own chipsets, wireless stacks, and hardware-software trade-offs while building the factory tooling that builds, provisions, and flashes devices at scale.
- Own embedded technical direction: select MCUs (ESP32, nRF), wireless stacks (Matter/Thread/Zigbee/BLE/Wi-Fi), and hardware-software trade-offs across multiple product lines.
- Shipped Matter-certified smart home devices (24 GHz occupancy radar sensor, smart switch, RGBCW light driver, curtain controller, multi-zone thermostat) using ESP-IDF and nRF SDK.
- Built a Python-based meta-build system over ESP-IDF that handles multiple ESP-IDF/ESP-Matter versions, device types, provisioning methods, network types, and chip variants.
- Designed and deployed a mass-manufacturing certificate provisioning and device flashing workflow (USB + BLE) with a web companion, managing binaries, versions, certificates, and OTA servers.
- Implemented OTA updates over BLE/USB and DCL-based Matter OTA, including rollback-aware image management and low-power optimizations down to ~20 µA.
- Optimized Thread border router stability and OpenThread self-healing behavior for reliable mesh operation.
- Collaborate cross-functionally with chip vendors (Espressif, Nordic), KNX/appliance engineers, customers, and factory teams to align requirements and deliverables.
Built firmware and full-stack web infrastructure for IoT monitoring systems, including remote electrical transformer and solar greenhouse monitoring in Nepal.
- Developed ESP32 firmware and MQTT/cloud backends for remote monitoring systems using BLE, Wi-Fi, and cellular connectivity.
- Engineered end-to-end IoT systems: sensor firmware, REST/MQTT APIs, Angular dashboards, and Django admin tools.
- Led Git workflows and mentored interns on embedded and web development.
- Researched ISO-15118, IEC-62196, and OCPP 2.1 for EV AC/DC charger and fleet communication projects.
