Frontend developer and data storyteller with 6+ years of professional software development experience, specializing in 3+ years of interactive data journalism and visual storytelling. I translate complex datasets into award-winning, human-centered digital experiences using JavaScript, D3.js, HTML, CSS (SASS) and modern web technologies.

My work sits at the intersection of code, design, and journalism—collaborating closely with writers, editors, researchers, and designers to create interactive narratives that reach millions of viewers across 40 languages. I'm passionate about web accessibility, responsive design, and crafting experiences that make data meaningful, memorable, and accessible to diverse global audiences.

When I'm not coding, you'll find me playing violin, sketching, reading, or exploring the best eateries in Delhi.

Always Online. Rarely Connected.
My first byline: A data-driven longform feature exploring the growing loneliness epidemic in an increasingly connected world. I took full ownership of this project—conducting in-depth primary research interviews, analyzing public health datasets, creating interactive data visualizations, designing the visual narrative flow, and developing the immersive storytelling experience from concept to launch. Published across six Indian languages, this piece demonstrated how frontend development serves journalism, turning complex sociological research into an accessible, emotionally resonant digital story.

From Delhi to Chennai, Indian cities are getting hotter
Built an immersive interactive exploration of urban heat inequality across six Indian cities, combining interactive heatmaps (MapLibre with pre-rendered raster tiles, zoom levels 9–15) with Canvas API animations that reveal two decades of urban expansion from 2000–2020 using Landsat satellite imagery. This sophisticated geospatial visualization project demonstrates the power of combining low-level charting and mapping libraries to create engaging storytelling experiences that communicate climate data at both granular and landscape scales.

How bad is Delhi's air?
Award-winning data visualization (Best Data Visualization, WAN INFRA 2025). Built an interactive visualization analyzing 11 years of air quality data across Indian cities using GSAP-powered animations and real-time API integration. Hundreds of SVG rectangles dynamically transform into bar charts revealing long-term PM2.5 trends, while an interactive hero carousel enables seamless exploration across multiple cities with hourly updates from IQAir's API. This project demonstrates how animation, real-time data, and intuitive interaction design transform environmental data into engaging, accessible storytelling.
