• I moved to the position in Strategy and Architecture. Our team reports into the CTO and has responsibility for determining the architectural vision and practice for JET. I lead on many of the architectural initiatives for this team.
• I am the engineering lead for the One programme which seeks to merge the various Just Eat Takeaway eCommerce stacks into a single system. I advise on architectural constraints, and work with the CTO, engineering and product directors, heads of engineering and principals to define the components that will comprise the One platform.
• I instituted an architectural advice process to review ADRs, raised by individual teams for work items as part of a programme. The process is based on the paper by Andrew Harmel-Law on "Scaling the Practice of Architecture, Conversationally"; it provide advice to teams on design and implementation. Through this I provided technical advice to varied programmes of work.
• I led on the creation a set of architectural principles to guide on future software design, engaging technical leaders throughout the organization. I encouraged guilds to support this with practices as "standing advice".
• I regularly provide ad-hoc advice to stakeholders across engineering, delivery and product on architecture and strategy issues; what Gregor Hohpe would call "riding the architecture elevator."
• I contributed code to the Just Eat platform to ensure that I remained in touch with the day-to-day developer experience.

• I joined Just Eat as a Principal Engineer in Integrations. In a self-directed role, my job was ensure good practice around inter-process communication. Working with internal guilds, I worked to define standards and best practices for HTTP APIs and Event Driven Architectures and ran architectural design workshops for teams in these areas.
• I led on the "Goldilocks" initiative to improve our service boundaries by right-sizing them to sub-domains. This work involved identifying sub-domains, beginning with an off-the-shefl model from APQC for retail, and then using techniques such as value stream mapping, event storming and event modelling with teams to refine this model for Just Eat's sector. The result was the identification of a number of sub-domains and a mapping of existing features onto those sub-domains, to allow teams to coalesce and simplify the service estate.
• I worked to create a plan to improve Event Carried State Transfer, adding Kafka as a protocol for series events alongside the discrete events from SNS.
• I introduced AsyncAPI to JET and envisioned and prototyped tooling to use it to deploy our messaging infrastructure (queues, topics etc.). I supported the messaging integrations team in taking that from prototype to product.
• Finally, I was the worksteam lead on a project to determine how Just Eat could integrate its platforms more closely, leading a cross-organizational team looking at how the individual hub-and-spoke broker based platforms could interoperate.
