David Ramirez
Sean was my manager for the last 9 months and it was an absolute pleasure to have him. He is all kind and he is always open to helping with whatever thing you need. I have learned a lot from him. From managing people to dealing with projects and complex tech teams. I'm very happy to have had the opportunity of working with him and he has been an inspiration for wanting to be an engineering manager myself. Thanks mate!

I worked with good friend Sean for a couple of years in a small team of ruby developers in Manchester. Sean's humour in a team make the workplace fun and enjoyable, he understands problems and how to solve them well and is not afraid to get his hands dirty in legacy unfamiliar code. Since Sean left On the Beach we have kept in touch on regular monthly meet-up's and instant messenger. Sean is a great community contributor and friend. Thank you Sean for asking me to write this recommendation for you.

Engineering Director, Core

Jan 2023 - Present
As engineering head of the core group, I am responsible for 45 engineers and managers across 7 teams. The group is responsible for the core systems and APIs on which other offering-specific groups at Stuart can build software, including functionality for billing/pay, package/delivery lifecycle, courier and client lifecycle, fraud detection/prevention and customer support tools.In 2023, our division so far has delivered:- PIN code at drop off. In partnership with our large enterprise clients, we enabled a security feature to allow end-customers to give their courier a PIN for high value items proving they are the intended recipient.- Contributing to company-wide efficiency initiatives we reduced the cost of our customer support tooling by over €100K/year- We shipped enhancements to fraud detection systems to detect couriers who spoof their GPS locations in order to receive more orders.- We began an ambitious long-term strategic project to move from a monolithic solution to event-driven microservice architecture.My input to the success of the group includes:- Organising a series of workshops to help teams plan how to extract functionality from a monolith into standalone services using event-driven architecture.- Creating a technical design process for new services and reviewing proposed system designs, giving clear feedback to the teams and helping guide them to pragmatic and realistic solutions that intentionally make appropriate trade-offs.- Managing data compliance initiatives with OpenMetadata to allow for tagging of PII data- Creating a detailed Udemy training course to help engineers learn how to diagnose production issues and resolve them as part of a culture shift towards "you build it, you run it".Tech choices: Node/TypeScript, Ruby on Rails, Elixir, Scala, Kafka/Avro, Docker, AWS, Spinnaker, Kubernetes, ArgoCD, Jenkins.
