Big Data Developer in Mumbai, Maharashtra, India

Created a near real-time electricity and carbon tracker for India for use for policy analysis. The data for the tracker is continuously scraped from meritindia.in, stored in an AWS RDS instance, and served to the website via an API using AWS Lambda. The website itself uses Vue.js and plotly.js. It was featured in the Wall Street Journal - https://www.wsj.com/articles/solar-power-is-beginning-to-eclipse-fossil-fuels-11581964338?mod=hp_lead_pos5

Created a time tracking tool for Indian lawyers to help Indian lawyers fill out their timesheets more quickly and ensure they don't forget about any billable work they've done. The tool integrated with Outlook/Google emails and calendar, as well as OneDrive, using OAuth, to give users a summary of the work they've done by parsing emails, calendar events and files worked on.

Successfully piloted the tool with two medium-sized law firms, and iteratively improved it to meet customer needs.

Led design, development, sales, and marketing for the product.

Used AWS Lambda with API Gateway as the back end, and DynamoDB as the database. Also used Python, Pandas, AWS S3, and SES to generate and send out billable work summaries to users via email. Used AWS Cloudwatch to automatically generate and send out billable work summaries to users weekly. Used the Microsoft Graph API and Gmail and Google Calendar APIs to read user data.

Used Google Ads and Analytics to sell to users, Leadpages to host our landing page, and a combination of personal referrals and cold emails for sales.

Created and launched an Android app to make governance more accountable by allowing users to post about issues they face, view existing issues posted by other users, and hold elected officials accountable to their actions.

This uses a Ruby on Rails back end hosted on Heroku with MongoDB as the database.

Created a fully-automated Instagram page that scrapes and reposts photos of food from Mumbai, crediting the source. Trained a neural network using transfer learning to classify photos of food, and trained a random forest to predict which users are likely to follow the page. All of this is hosted on an EC2 instance.

Built a scraper using Python, Pandas, and Tabula to extract data about doctors in the Indian state of Haryana from PDFs and graph various statistics about them.

Created an Android app to connect buyers with local sellers of items. The buyers can post for items they would like to have made, and sellers can bid on the price they would charge to make the item. Used Parse as the database and for authentication.

Created a WhatsApp bot which crowdsources reports of fake news and works with text, photos, videos and audio. I used Python, Lambda, DynamoDB, API Gateway, Docker, ECR, ECS and S3 for this.
Users can forward suspected fake news to the bot to report it, or see how many other users have reported it and the reasons they reported it.

Built a reservation manager for restaurants, built using React for the front end and Firebase for the back end and authentication.

The manager allows restaurants to log in, create tables, create/edit reservations, and see a summary of reservations on a given day.

The Toptal React Academy is an exclusive learning program that teaches the React framework to select members of the Toptal network. After a month of study, all graduates are tasked with completing a 30-40 hour final project to build and deliver a React app from scratch. The above is a walkthrough of my final project.
