I'm a Python Backend Developer passionate about building IoT systems, real-time data pipelines, and smart infrastructure platforms.
With experience designing and developing BAS/BMS (Building Management Systems) and energy monitoring systems, I focus on clean architecture, performance optimization, and system reliability.
- 🔧 Experienced in Python (Django), PostgreSQL, and MQTT/Modbus for IoT integration
- 🌐 Designed large-scale IoT data collection systems (Energy, Water, Air Quality, Fire Alarm, etc.)
- 🧩 Skilled in Database design, system architecture, and real-time monitoring dashboards
- 🧑💻 Enjoy solving complex problems and optimizing queries for performance
- ⚙️ Familiar with Nginx, and Windows/Linux Server environments
- 🎯 Love building practical systems that connect hardware, data, and people
- 🤝 Strong sense of ownership — I take responsibility from design to deployment, ensuring results that matter
- 🧭 Collaborative mindset with proven experience leading small teams and supporting cross-functional work
- 💡 Believe in clear communication, continuous learning, and accountability in every project
