## Projects

### Innovatrix – AI Operational Risk Early Warning System (2026)
AI-powered IT analytics platform built in a 24-hour hackathon to predict and flag operational risks in software project management.

- **Discipline:** AI / ML
- **Role:** Full-Stack & AI Engineer
- **Status:** Completed
- **Stack:** Next.js, React, Tailwind CSS, FastAPI, Python, PostgreSQL, Machine Learning Models, Docker, Monorepo Architecture
- **Case study:** https://gauravrathva.me/projects/innovatrix-risk-analytics-hackathon
- **Problem:** Delivery risk in software projects usually surfaces as a missed deadline — long after the signals that predicted it appeared in daily logs, bug trends, and task churn. Project managers are reacting to outcomes instead of leading indicators.
- **Approach:** Treat project telemetry as a time series and score it continuously. Rather than another reporting dashboard, the system watches team activity for anomalies and surfaces a ranked risk view answering one question: which projects need attention this week?
- **Architecture:** Full-stack monorepo. Next.js frontend for the analytics dashboards, FastAPI service exposing scoring and anomaly endpoints, PostgreSQL for project and activity history, and ML risk models running behind the API. Containerised with Docker; designed for Jira and Kaizen ingestion.
- **Result:** A working end-to-end prototype delivered inside a 24-hour sprint — risk scoring, anomaly detection, cost-overrun forecasting, and automated reporting, with role-based access already in place.

### Calzye – Free Online Calculator Suite (2025)
A free, privacy-first suite of 48+ online calculators for math, finance, HR, tax, health, and unit conversions — all running client-side with no sign-up.

- **Discipline:** Web
- **Role:** Solo Developer
- **Status:** Live
- **Stack:** Astro, TypeScript, Tailwind CSS, Cloudflare Pages, Schema.org / JSON-LD
- **Case study:** https://gauravrathva.me/projects/calzye-calculator-hub
- **Live:** https://calzye.com
- **Problem:** Online calculators are a solved problem that nobody solved well: the common ones are ad-heavy, slow, and quietly send your salary or health figures to a server. And a 48-tool site normally means 48 sets of metadata to hand-maintain.
- **Approach:** Ship every calculation to the browser so no user input ever leaves the device, and treat the calculator list as the single source of truth — structured data, sitemap, robots.txt, and llms.txt are all generated from it, so adding a tool requires no SEO upkeep.
- **Architecture:** Astro static output on Cloudflare Pages. A shared calculator dataset drives routing, search, category filtering, FAQ blocks, and every generated metadata artefact. Critical CSS is inlined, analytics deferred, and fonts loaded non-blocking to protect the critical path.
- **Result:** A live suite of 48+ tools across math, finance, HR, health, and conversion, with dark/light theming and no flash of unstyled content — and an SEO layer that scales itself as new calculators land.

### Fresh Cart (2022)
Android-based local grocery ordering platform connecting users with nearby stores for real-time ordering, tracking, and UPI payments.

- **Discipline:** Mobile
- **Role:** Android Developer
- **Status:** Completed
- **Stack:** Android (Java), Firebase Realtime Database, Firebase Authentication, Firebase Cloud Storage, REST APIs, UPI Payment Integration
- **Case study:** https://gauravrathva.me/projects/fresh-cart
- **Problem:** Neighbourhood grocery stores had no way to take orders online. The delivery apps that existed served chains and large catalogues, leaving small local shops — and the customers who prefer them — offline.
- **Approach:** Build both sides of the transaction rather than just the storefront. One application serving two roles: customers discovering nearby shops and tracking orders, store owners managing inventory and fulfilment, sharing a single realtime backend.
- **Architecture:** Native Android in Java, with Firebase Realtime Database for live order state, Firebase Authentication for both user roles, and Cloud Storage for product imagery. UPI handles payment so no card data is ever touched.
- **Result:** A complete working prototype covering the full loop — discovery, cart, order placement, live status tracking, UPI payment, and store-side fulfilment — delivered as a two-person capstone.
