Things I build, end to end

Open-data dashboards for a city and a state, a global cost-of-living tracker, an equity screening pipeline, and an Android medication reminder. Data pipeline, front end and deployment — all of it mine.

Kolkata City Dashboard

Nineteen domains of open data about one city — demographics, climate, air quality, transport, budget, crime, health — stitched into a single interactive portrait.

Thirty-plus primary sources arrive as APIs, CSVs and PDF-only government releases. A Python pipeline cleans and aggregates them into JSON committed to the repo; Next.js inlines that at build time, so every chart is pre-rendered with no runtime database. Every figure links back to its source, and the known limitations are published rather than hidden.

StockPicker

A six-stage pipeline that scans all ~1,800 NSE-listed stocks and ranks the top 50 — fundamental filters, nine technical and seven momentum signals, then a random forest / XGBoost / logistic regression ensemble. Every pick ships with the score breakdown behind it.

How these get built
Every project here is mine end to end — sourcing the data, writing the pipeline, building the interface, and shipping it.
