Experience

• Constructed IoT simulator to perform end-to-end testing on qualifying firmware against elevator emergency phone systems to verify full functionality. Data piped to PostgreSQL database for further data cleansing and additional pipelines for visual dashboards displaying real-time alerts and status updates.
• Applied data analytics and machine learning models to historical data from elevator controllers to predict breakdowns. Training, fine-tuning, and live field tests reinforced a high confidence rate at .75 accuracy. Predictions from a single controller and callback type have an estimated savings of $60,000 a year.
• Programmed service to run and collect data from CB3/CB4s to analyze elevator trip behavior. All data reported to servers via MQTT and error code / sub-code messages. Data was further used to decrease non-communication module rates from 25% to 17.5% in SECs 150,000-unit portfolio within a year.
• Implemented rules logic for controller characteristics via code and subcodes in SAP NWDS. Each controller rule base is used to alert and flag errors into a remote monitoring platform to notify the support team and Schindler’s customers.
• Collaborated with INDU team to program and build emergency UPS replacement for HUAWEI battery hardware / firmware. UPS communicates through RS232 serial connection with event handling to adapt to all hardware malfunctions.

• Designed mobile layout for both Android and iOS mobile devices.
• Implemented mobile-friendly Figma design to allow better user interface on varying devices from resolutions spanning 360 x 380 to 1920 x 1080.
• Reduced latency with AWS Lambda to improve infinite scrolling image gallery.
• Resolved Jira tickets daily for bugs or abnormalities with website and mobile application.

• Increased monthly metrics of sales, turnaround time, and reviews from 55% to 80% satisfaction of more than 10 years of customer feedback within 3 months of joining management through customer service and professional repairs.
• Maintained a detailed inventory of electronic, cosmetic, and other parts worth over $200,000 alongside financial records bi-weekly to ensure monthly growth in profits.
• Managed a team of 6 technicians by providing weekly training on difficult repairs and various software applications to further personal and professional development.
• Exceeded daily sales and product add-on quotas by offering customers more sustainable methods of saving revenue long term through additional insurance or protection of devices.

• Designed antenna to fit CB3/CB4 needs and constraints to ensure stable connectivity to over 50,000 units in SEC.
• Validated firmware for the first iteration of Schindler’s CB3/CB4 through stress testing and hardware documentation.
• Engineered solutions for noise interference issues with the CB3/CB4’s antennas leading to a significant increase in quality of RSSI, SINR, RSRQ, and RSRP allowing qualification for emergency communication service requirements.
• Optimized and reduced the cost of hardware assemblies and manufacturing.
