Work Experience

Honghui Energy (South HQ) / Guangdong Ruilai Huakong Technology Co., Ltd.

Software Engineer ｜ 2025.06 - Present ｜ Zhongshan, Guangdong
▸ A wholly-owned subsidiary of Honghui Energy (leading flywheel energy storage enterprise), responsible for core system development at the Southern R&D and production base

  • Participated in the 0-to-1 construction of the Southern base’s energy storage software ecosystem (edge-side-cloud), aligning with group technical standards; delivered software modules directly serving production line equipment testing and on-site delivery.
  • Collaborated closely with hardware and electrical protocol teams to resolve communication congestion and signal jitter issues in complex industrial environments, ensuring reliable interaction between power electronics devices and upper-layer systems.
  • Facilitated team Git collaboration and code review practices; developed multiple universal debugging toolchains to replace manual lookups with visual parsing, significantly reducing on-site troubleshooting cycles.

Key Projects

Flywheel Energy Storage Monitoring System (FMS)

Core Developer ｜ C++ / Qt6 / Modbus-TCP / CAN / SQLite / IOCP ｜ 2025.06 - Present

  • Refactored Modbus-TCP communication link with Windows IOCP and connection pooling, resolving UI blocking caused by high-frequency data acquisition, reducing CPU usage by ~15%.
  • Developed dedicated debugging module for DSP control boards (based on ZLG CAN SDK), implementing bidirectional dynamic parsing of IEEE 754 floating-point numbers and HEX frames, supporting multi-byte order (CDAB/ABCD) auto-conversion and register semantic mapping, replacing manual CANTest workflows and significantly improving hardware-software integration efficiency.
  • Designed sliding window algorithm for alarm signal debouncing; implemented high-frequency message persistence based on SQLite WAL mode, enabling efficient local retrieval and tracing of historical on-site data.
  • Promoted CMake modular builds and integrated Crash Dump exception capture mechanism, compressing full compilation time from 5 minutes to under 50 seconds, significantly enhancing development iteration and on-site troubleshooting efficiency.

Flywheel Energy Storage Edge Communication Gateway

Core Developer ｜ C / STM32F407 / FreeRTOS / MQTT / Modbus / IEC-104 ｜ 2025.12 - Present

  • Responsible for edge gateway core business logic based on STM32F407 and FreeRTOS, polling underlying devices via Modbus/RS485 downwards and establishing time-series data channels to the cloud via MQTT upwards.
  • Implemented protocol parsing and mapping conversion among Modbus, IEC-104, and MQTT, enabling a closed-loop data interaction across device-side, power protocol-side, and platform-side.
  • Designed and implemented time-series data caching and breakpoint resume mechanism for weak network conditions, ensuring data integrity during network fluctuations.

Flywheel Energy Storage Smart Cloud Platform

Backend Developer ｜ Golang / Docker / Podman / Redpanda / PostgreSQL / Redis ｜ 2025.06 - Present

  • Participated in core backend service development for the energy storage cloud platform (based on Alibaba Cloud Linux), handling high-frequency device data ingestion, protocol parsing, and time-series storage.
  • Led deployment environment configuration using Docker for local development and Podman rootless combined with Shell scripts for production, achieving secure isolated deployment with rootless accounts.
  • Introduced Redpanda message queue to decouple data acquisition and storage layers, smoothing concurrent write peaks; independently designed authentication middleware maintaining secure session state via JWT (AT/RT) and Redis.

Modbus-Tools (Personal Open Source Project)

Independent Developer ｜ C++20 / Qt6 / CMake / CI-CD ｜ 2025.12 - Present

  • Developed cross-platform debugging tool using channel/transport/session/parser layered architecture with built-in visual frame builder, eliminating tedious manual table lookups and hexadecimal frame concatenation.
  • Built Frame Analyzer core parser supporting automatic protocol recognition, custom scaling conversion, and register semantic annotation; supports JSON/CSV configuration import/export, compressing on-site troubleshooting time from minutes to seconds, improving integration efficiency by 5x+.
  • Established fully automated CI/CD pipeline via GitHub Actions for automatic build and release upon code push; client features built-in multi-language switching and Auto-Updater mechanism, ensuring agile iteration in field deployments.
