Ricky's Projects

Some projects I've worked on

Prism A friend and I built a decentralized options exchange on Ethereum in 2015. We created a order execution exchange for ETH options, binding options in Solidity contracts, using Oraclize for price feeds and IPFS to offload data. Apparently this was the second ETH derivatives exchange built globally. Live demo of the app, and paper here.

Hide I built a Chrome extension to harness remote CPU cycles to mine Monero. Click here for an article I wrote about my findings.

Cryptotrage I used to build market making and taking bots, using simple graph algorithms to find multi hop cross-exchange price arbitrages. Assets needed to be distributed across exchanges in the right amounts to execute - forecasting arbitrage windows and relocating was more complex than actually finding the mispricings in real-time. With market making back in 2015, I was able to consistently represent spreads representing up to ~10% of prices and for half a year, I was the only market maker for two low volume tokens.

LazyMe I built a program to do my Spanish Homework for me. Perdón, Señor Garcia! I had a semesters worth (1000s) of online exercises to do; so I wrote a script to navigate through the exercises and submit all the correct answers for me. I got an A.

Puma I built an iOS application which stores your notes in the cloud encrypted using private keys from the iphone's secure enclave. (Hybrid encryption for top performance and security.) Login with biometrics and a passphrase to decrypt your notes, so noone can see them even if the storage server is hacked.

Lucky 13 Joined a robotoics competition to race autonomous vehicles around a ~100m track and to escape an (prior unknown) labyrinth. I worked on localization, mapping, control and path planning. Website here

StyleX Although design is not my forte, I tried to create a personalizable website so you can store all your clothes and belogings online. Not only that, but you can try different outfits on a virtual-YOU to see what looks best. Save the outfits that look good. Check it out here
