Hi, I'm Marco Marassi.

About Me

I am currently a Software Engineer at Monzo.

Previously I was a Senior Software Engineer at Deliveroo in the Payments team, where I increased overall company revenue 0.5M GBP in the first three months after launching a re-design of the payment user experience, allowing the post-order tip feature to be de-composed from the existing monolith service and launch in 3 new markets, and for the new cash on delivery feature to be launched in Italy.
I've also led the system integration between the new DoorDash monorepo and the existing legacy Deliveroo infrastructure for subscription billing, collaborating with DoorDash, Deliveroo and Wolt's teams.
I've improved performance of rider paydays 12x - from 4h down to 20m, and decreased rider support queries by 75% on the rider payments and invoicing's legacy systems.
While there I also mentored 1 senior and 4 mid-level engineers by providing 1:1 coaching, from day-to-day problem solving, design and code reviews, conflict resolution, to sessions with practical homework-style exercises on specific technical topics.

Before Deliveroo, I worked as a Back-end Web Developer at Simpleweb. While there I led projects for early stage startups guiding customers through building their products: from POCs, passing through MVPs, to fully-fledged solutions for established companies. Doing so using technologies like Ruby on Rails and Sidekiq, Heroku and AWS, Laravel and PHP, NextJS, AlpineJS and TailwindCSS.

Before that, I have been Principal Web Developer at Somerset Design, and Technical Specialist for Mondago Ltd.

Outside of the office, you are most likely to find me at the local chess club, or chasing classic cars in the streets of town.
