02 / About

Less noise.
More useful UI.

I build interfaces where complex data becomes clear, useful, and easy to act on.

I’m Sai Teja Challa, a frontend developer with nearly 2 years of professional experience building responsive, scalable web applications, dashboards, and API-driven product interfaces.

At VoltVisionTek, I work on the core Battery Test Data Management Dashboard—turning real-time and historical voltage, current, temperature, and SOC data into interactive analytics with Plotly.js and Apache ECharts.

My wider toolkit includes Java, Spring Boot, MySQL, RESTful services, Git, Bootstrap, Python/Django, responsive design, debugging, and performance optimization.
