Senior Software EngineerTwitter Feb 2021 - Nov 2022San Francisco, Ca, UsI worked to build a new backend platform to serve search results, including building a full implementation of Twitter user search on top of it. We built this stack with modern tools and allowed the search product teams to iterate and experiment significantly faster than before. We launched this for 100% of Twitter’s >300M users.I lead a project to include Tweets from people you follow in search results in addition to results from people outside your network. The main search index isn’t well suited to return personalised results based on the accounts you follow. I drove the design and implementation of a new index which can supply additional search candidates from your follow graph.I lead a project to build a new platform for ranking Tweets at scale. I designed new systems to enable ML engineers to distribute light ranking models for experimentation and production without requiring knowledge of our real-time inference infrastructure. I designed it so that it can rank an order of magnitude more tweets than our previous light ranking system, providing better recommendations for users. -
Senior Backend EngineerMonzo Bank May 2017 - Feb 2021London, England, GbI joined the payments peam prior to the launch of Monzo’s current account product. I designed, built and maintained distributed payment processing systems (Mastercard, Faster Payments, CHAPS, Bacs, cash deposits) that are now used by over 4.5 million customers.I led the design and implementation of a new payments processor to handle cash deposits via integration with PayPoint, a company offering over-the-counter deposits in shops. Adding cash deposits was an important strategic feature to encourage customers to use Monzo as their primary bank account. The cash deposit system now handles over £500k worth of deposits a day, and has the least operational overhead of all of the bank’s payment systems, measured by the number of issues requiring manual investigation.I worked on the design and implementation of a Faster Payments gateway, the system responsible for maintaining connections with and routing payment messages to the UK Faster Payments network. This was a technically complex architecture project that required a live cut-over migration from a hosted 3rd party product, bridging physical and cloud infrastructure. This required extensive load testing and passing a full functional test suite from the payment scheme operator.I designed and built a system for ordering batches of physical mastercard debit cards, from multiple suppliers. Among the system’s responsibilities are assigning new unique card numbers to each card, encoding chip and magstripe data, and abstracting the embossing capabilities and label printing rules of each supplier.I was an incident manager for critical incidents - a member of a small rota of people to whom incidents were escalated if they required coordination and decision making beyond the expectations of first-line on-call engineers. E.g. facilitating communications between the executive team, customer support teams, press and regulatory communications teams. -
