  • Jaguar Land Rover and Gorillaz Code Breaking Challenge

    Competed and finished second out of 40,000 participants in the JLR code-breaking challenge, in collaboration with Gorillaz, by solving a series of technical puzzles and coding challenges in three days.

    The challenges were designed to test curiosity, persistence, lateral thinking, and problem-solving skills. For example, obtaining passwords and keys by analyzing sound waves, interrogating binary data hidden in images, writing JavaScript to mathematically align randomly swirling pixels, and manipulating color hues programmatically. Instead of questions or instructions, participants had to figure out how to crack the codes.

    For my prize, I was fast-tracked through JLR's recruitment process where they were seeking world-class engineering talent to build the software for their first- ever EV, the Jaguar I-PACE.

    Once onboard with JLR, I delivered software-over-the-air capabilities by sending binary deltas of Linux software and firmware to the car via 4G, enabling new features, bug fixes, and performance optimizations to be delivered to the car and installed, even while the car is in motion.

  • Freebets4all | AutoMatcher

    The AutoMatcher (no longer operating due to unavailability of odds data) was the world's first-ever automated matched-betting odds compiler.

    The system received changes to sports betting odds from 50+ sports betting providers, up to 100 times per second via a WebSocket. The odds were then stored in both SQL and NoSQL format and could be analyzed and queried to identify closely matching odds for the same betting market (e.g., correct score, match winner, and horse race winner) across different bookmakers to locate matched-betting opportunities.

    The opportunity could then be selected to show the user how to make a risk-free profit on the arbitrage situation by covering all outcomes of the event, often using bookmaker's free bets and bonuses to enhance winnings. The AutoMatcher then generated instructions in multiple languages to show the user how to place the bets using a variety of techniques, such as slight variations on a mathematical formula, depending on the type of bonus the bookmaker had to offer.

    This pioneering system helped Freebets4all become the UK's best-known matched-betting website, generating revenue via affiliate marketing and well-loved by the matched-betting community of 80,000+ users.
