Dedication to clean UI
I'm a Frontend Developer specializing in React.js, JavaScript (ES6+), and data-intensive web applications. At VoltVisionTek, I designed and built the company's core Battery Test Dashboard โ€” translating complex real-time sensor data (voltage, current, temperature, SOC) into clear, interactive visualizations using Plotly.js and Apache ECharts. I care deeply about performance, clean component architecture, and seamless user experiences. When I'm not coding, I'm learning something new. I'm always ready for the next challenge.
