Industrial Equipment Data Platform | Industrial Equipment Data Platform

Designed and implemented a production-oriented industrial equipment platform for equipment telemetry management, RBAC permission control, operation auditing, dashboards, and report workflows.

• Built a Flask + Jinja web application with REST APIs, SQLAlchemy models, MySQL persistence, Redis-backed sessions, and CSRF/session protection.
• Designed RBAC permission management with user, department, role, permission inheritance, effective permission cache, and audit log support.
• Implemented equipment data models and workflows for machines, measurement definitions, limit configuration, records, and event history.
• Developed MQTT-based telemetry services for configuration synchronization, heartbeat handling, and equipment data ingestion.
• Created operational pages for permission management, operation history, tool management, telemetry settings, dashboards, and reports using Bootstrap, jQuery, DataTables, and Chart.js.
• Packaged and documented deployment with Docker Compose, Nginx, Gunicorn, systemd, and Linux service operations.
• Validated RBAC behavior and performance with automated tests, including permission inheritance, cycle prevention, cache behavior, and API throughput under database load.

Tech stack: Python, Flask, SQLAlchemy, MySQL, Redis, MQTT, Docker Compose, Nginx, Gunicorn, Bootstrap, jQuery, DataTables, Chart.js

Wafer Test Management Platform | Wafer Test Equipment Management Platform

Built a web platform for wafer test equipment management, recipe/library workflows, wafer map operations, remote tool access, and runtime monitoring.

• Developed Flask APIs and Jinja-based management pages for recipe, algorithm/library, simulation, tester, file, batch, PCM log, and system modules.
• Implemented wafer map and shot map workflows for die selection, wafer-edge selection, chess-pattern selection, shot validation, die coverage, and sorting logic.
• Integrated noVNC, WebSSH, Socket.IO, and file management features for remote equipment operation and support workflows.
• Built parsers and upload flows for tester libraries, recipe/spec files, wafer definitions, probe settings, and related engineering data.
• Added equipment monitoring data structures for CPU, memory, disk, tester state, probe card life, PM count, clean count, lot information, and runtime status.
• Packaged deployment assets including Nginx, systemd services, simulator services, certificates, offline packages, and release scripts.

Tech stack: Python, Flask, SQLAlchemy, Flask-Login, Flask-SocketIO, Pandas, OpenPyXL, Paramiko, WebSSH, noVNC, JavaScript, D3, Bootstrap

Manufacturing Data Analytics Platform | Diagnostics and Quality Analytics Platform

Developed a data analysis and reporting platform for diagnostic logs, measurement data, statistical rule evaluation, charts, and daily reports.

• Built Flask REST APIs for manufacturing data search, filtering, configuration, detail retrieval, Excel export, daily reports, and statistics pages.
• Implemented statistical evaluation workflows with NumPy-based rolling-window calculations, conversion metrics, mean/stddev processing, and cache tables.
• Designed SQLAlchemy models and MySQL-backed cache workflows for high-volume diagnostic and measurement data.
• Created dashboard/report pages using Bootstrap, DataTables, Chart.js, box plot charts, date range pickers, and AJAX-driven filtering.
• Integrated third-party remote support services including noVNC, WebSSH, file access, and batch operations.
• Packaged services with Docker Compose, Nginx, systemd timers/services, PyInstaller build scripts, and deployment documentation.

Tech stack: Python, Flask, SQLAlchemy, MySQL, Redis, NumPy, Pandas, OpenPyXL, XlsxWriter, Docker Compose, Nginx, systemd, Chart.js, DataTables
