PARESHKUMAR AVAIYA

I’m a Senior Embedded Engineer with 12 years specializing in low-power IoT and wireless protocols—Amazon Sidewalk, LoRaWAN, and BLE. I’m one of the earliest Sidewalk integrators globally, shipping FUOTA systems, dual-protocol NCP modules, and secure boot implementations across 15+ products for Fortune 500 clients.

I lead end-to-end firmware from hardware bring-up to mass manufacturing readiness, optimizing resource-constrained systems and delivering real-world reliability at scale. At OXIT LLC (US-based remote), I architected a modular multi-protocol Network Co-Processor (NCP) with dynamic runtime switching between Amazon Sidewalk, LoRaWAN, and BLE on a shared SX1262 radio, and I modernized legacy codebases by rewriting 70% of the firmware.

I also build robust OTA and security capabilities, including a custom unicast FUOTA for Amazon Sidewalk (supporting BLE/FSK/CSS link types with mid-session transitions) and secure boot with ARM TrustZone plus tamper detection. I coordinate field deployments, manufacturing provisioning/testing, and compliance work like FCC test-mode firmwares—grounding my engineering in what actually ships and survives.
