Professional Experience

Software Development Engineer II Apr 2026 – Present
Amazon Connectivity Team
  • Cross-Layer Performance: lifted end-to-end Wi-Fi throughput 2.36× (10.59 → 25 Mbps) on FreeRTOS via profiling from PHY through SDIO, kernel, and application; resolved IMI memory bottleneck (SDIO), TCP shared-lock and mutex contention (kernel), and application memory contention, plus CPU overclock tuning.
  • Dynamic NVRAM/CLM Loading: architected runtime loading from flash, enabling a single firmware image to serve multiple SKUs and regulatory regions without per-region rebuild.
  • Wireless Bring-up: led Wi-Fi/BLE bring-up on next-gen ASIC platforms; integrated wireless chipset BSPs/SDKs into production FreeRTOS firmware for NPI programs.
  • RF Validation Firmware: owned delivery of purpose-built images to unblock RF, antenna, and platform validation engineers across NPI cycles.
  • Cross-Layer Debugging: drove root-cause analysis and resolution of 10+ firmware tickets across Wi-Fi, BLE, and platform stacks, from internal validation reports through field escalations.

Software Development Engineer I Aug 2023 – Mar 2026
Amazon Connectivity Team
  • Secure Provisioning: built a modular BLE setup subsystem from scratch with end-to-end encryption and dynamic country-code configuration, enabling global SKU deployment from a single firmware base.
  • Measurement-Driven Optimization: characterized unstable network reconnection and redesigned DHCP logic, reducing reconnection latency by 76% under challenging environments.
  • Latency-Sensitive Performance: tuned WMM QoS (EDCA) parameters to prioritize latency-sensitive traffic, improving p99 latency for streaming services by 24%.
  • Power Efficiency: developed Wi-Fi power-saving and wake-up pattern mechanisms, extending battery-operated IoT device standby from 40 to 65 days.
  • Sustained Ownership: resolved 50+ firmware tickets across Wi-Fi, BLE, and connectivity stack from internal validation and field reports.
