01

RemindMe

Medication, simplified.

A HIPAA-compliant Android medication reminder that makes adherence effortless. Scan prescriptions with ML Kit OCR, add meds via voice, and never miss a dose. Built entirely with AI-assisted development to prove what one person and the right tools can ship.

The Insight
Medication non-adherence costs $500B annually. Existing apps are cluttered and assume tech-savvy users. RemindMe strips it back — scan, set, forget.
What's Next
Multi-patient support for caregivers, cloud backup, and a premium tier. Exploring partnerships with pharmacy chains.
02

StockPicker

1,800 stocks in. 50 out.

A six-stage analysis pipeline that scans every stock on NSE — combining fundamental screening, technical signals, quant momentum scoring, and a three-model ML ensemble — to surface the 50 stocks most likely to grow. Includes a full web UI with deep-dive profiles, portfolio builder, swing trade setups, paper trading, and exportable reports.

The Insight
Retail investors drown in stock tips but lack systematic frameworks. StockPicker replaces gut feeling with a transparent, multi-signal scoring engine — every pick comes with a full breakdown of why it scored the way it did.
How It Works
5-layer data pipeline with near-zero gaps → macro regime detection → hard fundamental filters → 9 technical + 7 momentum signals → RF/XGBoost/LR ensemble → risk-adjusted final ranking. All thresholds configurable via YAML.
03

Cost of Living Tracker

193 countries. One dashboard.

An interactive global cost-of-living tracker that visualises how prices have changed across 193 countries over 1, 5, and 10-year windows. Choropleth world map, multi-category breakdowns (CPI, food, energy, education), country comparisons, and PPP-adjusted views — all powered by World Bank and FAOSTAT open data.

The Insight
Inflation is felt locally but driven globally. Most dashboards show one country at a time. This puts the whole world on one screen — compare your country against any other, across any category, in seconds.
What's Next
Personal basket weighting, threshold alerts, housing and healthcare categories, and historical event overlays on trend charts.
04

Kolkata City Dashboard

18 domains. 30+ sources. One city.

An interactive open-data dashboard for Kolkata spanning demographics, elections, land use, climate, air quality, water and flooding, healthcare, disease, education, crime, judiciary, transport, budget, real estate, employment, energy, and digital infrastructure. 30+ open data sources stitched together, a 141-ward interactive choropleth, 75 years of IMD climate records, a 40-year metro ridership series, and cross-domain correlation insights — with automated refresh via GitHub Actions.

The Insight
Open city data exists but is scattered across PDFs, CSVs, and government portals. This dashboard stitches 30+ sources into a single interactive view — making Kolkata's story legible at a glance, from 1690 to 2026.
What's Next
Real-time traffic heatmaps, ward-level budget tracking, and comparative analysis with other Indian metros.
05

West Bengal Through Data

Zooming out from the city to the state.

A companion to the Kolkata City Dashboard that lifts the lens from a single metro to all of West Bengal — district-level demographics, economy, climate, health, education, and infrastructure stitched from open government sources into one interactive view.

The Insight
A city dashboard answers "how is Kolkata doing?" A state dashboard answers "how does Kolkata compare to the rest of Bengal?" Both questions need the same treatment — open data, stitched together, made legible.
What's Next
District-level choropleths, rural vs. urban splits, and direct comparisons between Kolkata and the rest of the state.
Philosophy
The best way to complain is to build it.
