• Uses several open source UI components and REST APIs.
• Open-sourced under an MIT license: Github.com/dritani/Antique-Book-Scan

Google FooBar Challenge September 2016

• Google FooBar is a programming challenge that Google inserts in its search engine results for people who extensively search for programming-related terms.
• The puzzles require knowledge of algorithms and data structures and place tight constraints on time and memory efficiency.
• Puzzles get progressively harder with each level.
• I completed all five levels (15 puzzles total) and received a call from a Google recruiter after finishing level 3; proceeded up to the second phone interview.


• A freelance job aggregator website; it scans websites (currently only Craigslist) for iOS freelance job opportunities
• Hosted on an Amazon EC2 instance with a Python SimpleHTTPServer as the back-end, simple HTML/CSS for the front-end, and a daily Cron job to run the scraper.

Av0cado.com Back-end Code

• Built this web scraper written in Python to scan Craigslist for freelance job opportunities.
• It uses the Python requests library to make HTTP requests, the "threading" library to throttle the number of concurrent connections, and many different user agents and proxies, to avoid getting IP-banned.

VBA Automation Project

• Contains several buttons that automate parts of the workflow of the portfolio associates at the financial company where I used to work at.
• One button opens emails in Outlook, saves attachments, opens them, and copies their content to other Excel files.
• Another button opens Axys (portfolio management software) and simulates mouse clicks and keystrokes to run the daily reports and save the results automatically.

Jewelry Supplier Inventory Macro

Built three Excel macros to transfer jewelry images, quantities, prices, and more from one Excel sheet belonging to the supplier to another one meant for the retailer. Saved the client two days' worth of monthly manual labor.

Enable My Team (via Toptal)

Added features and fixed bugs on a PDF annotation app currently in production.

Durst Sebring Imaging Systems (via Toptal)

• Fixed bugs in an internal Python tool that generates website front-ends.

Video Compressor Mobile App

I developed a video compression utility app and published it to the App Store as an independent developer. The app was built using React Native and acted as a wrapper around the FFmpeg multimedia library.

Custom Employee Management Software

I developed the client-side portion of an Employee Management Software, custom-built according to customer specifications. The client-side consisted of a React.js web front end and a cross-platform React Native app published on both app stores.
