Technical Director / R&D Leader

I founded Beijing Hualazimi Technology and lead end-to-end product development for the PulseRing smart-wearable health management platform. I own technical solution design, system architecture, device integration, mobile applications, device cloud services, and operations-console implementation.

I designed the boundary between BLE device communication in the app and cloud services for account binding, health data, and device state. I built a FastAPI and MySQL device cloud with 91 business APIs, integrated Bluetooth SDKs, delivered uni-app and Flutter mobile tracks, added TOTP authentication and audit capabilities, and validated ESP32-S3 voice and remote-LLM prototypes.

I owned solution design and delivery outcomes for financial-sector clients in northern China, including Bank of Beijing, Hua Xia Bank, and Huatai Securities. I led engagements from solution architecture and technical review through delivery, launch, and acceptance.

I led low-code platform product design and deployments, contributed to the LogMind AI agent platform, and defined the architecture for security data warehouse and situational-awareness programs. My work established multi-source security-log aggregation, governance standards, regulatory-reporting pipelines, data-security compliance controls, and ML/LLM-ready data marts.

I managed a 40-engineer R&D organization covering big data, Java backend, and mobile development for in-house systems supporting the Sports Lottery Administration Center. I set technical frameworks, implementation plans, staffing, delivery cadence, quality processes, and cost controls, while participating in organization-level technology decisions and architecture reviews.

I defined the roadmap for the lottery internet big-data platform using the Hadoop and Spark ecosystem and delivered user-profiling and service-monitoring initiatives. I led user identity unification through device fingerprints, tag-system and API development, RFM and decision-tree models, and CMMI ML3 process, training, and quality initiatives.

While employed full time at China Sports Lottery, I assembled and led a seven-person cross-functional team to deliver an electrochemical energy-storage SCADA system from requirements through on-site commissioning.

I established the system ingestion architecture using GPS time synchronization, MQTT uplink transport, InfluxDB time-series storage, and integrations with BMS, PCS, EMS, AGC, protection relays, and meters. The solution supported more than 3,000 monitoring points and was deployed at multiple Shanxi power plants.

I reported to the CEO and led a 20-person R&D center, participating in product-direction decisions and establishing organizational structure, development planning, and delivery-quality mechanisms.

I led the architecture for subscription e-commerce, social-selling distribution, and cross-border e-commerce platforms across web, iOS, Android, and tablet products. I also delivered Chongqing Customs 2.0 integration, established component selection practices, and introduced change-control mechanisms for predictable product delivery.

I reported to the CEO and managed a 12-person R&D team, leading organizational development, architecture optimization, technical training, and product delivery.

I led development of the YouZhi HR system, including automated resume-email triage using Bayesian classification and NLP. The platform accumulated more than 10 million resume users after launch and iteration, and I also led a POC for a Ministry of Education vocational-student management system bid.

I performed architecture design reviews and developed overall hardware, software, and database solutions. I also delivered core technical breakthroughs, framework code, and engineering mentoring for products and projects.

I led architecture for the Yunnan Copper MES program, a project with investment exceeding RMB 10 million, including SAP XI integration through successful go-live. I additionally supported POCs and technical walkthroughs for MediaTek, ZEISS, China Construction Bank, and HP Finance.

I led a six-person engineering team delivering a bulk agricultural-commodity electronic trading system.

The system covered trading, customer management, settlement, and fulfillment subsystems, and I was responsible for team leadership and technical delivery.

I led teams delivering outsourced software projects for Microsoft, Siemens, and IBM.

My responsibilities included project delivery, technical training, team coaching, and engineering coordination.

I contributed to a national grain-depot information management system covering 25 million tonnes of grain capacity.

I also worked on a weighbridge plugin platform and related enterprise software-development activities.

I worked on software development, whitepaper writing, and pre-sales prototyping during my early software-engineering career.

This role established my foundation in enterprise application development, technical communication, and solution demonstration.

Bachelor of Engineering in Automation from Northeastern University (985). Received National First Prize in the 7th Challenge Cup National Undergraduate Academic and Technical Works Competition in 2001.
