November 2022 - November 2024

Summary

Led the design and delivery of a unified webhook and event API, migrating the platform from Pulsar to Kafka to serve product teams across the organisation. Also implemented RBAC authentication with custom SCIM, and built observability tooling using OpenTelemetry. Centralised SDLC compliance controls via GitHub workflows, reducing engineering overhead across multiple teams.

Global Developer Onboarding Experience at Intuit (QuickBooks)

December 2020 - February 2022

Summary

As a side initiative alongside my core role, designed and led the onboarding experience for backend developers, which was subsequently adopted globally across Intuit's engineering organisation. Co-founded a global DDD community and ran engineering-wide workshops across multiple regions. Created and led regular Lunch & Learn sessions to upskill engineers internationally.

Reviewer — The Art of Agile Development (2nd Edition) by James Shore

Technical Reviewer
James Shore
October 2020 - September 2021

Summary

Reviewed the second edition of The Art of Agile Development by James Shore, one of the most respected books on agile software engineering. Contributed feedback on code language conventions for non-native English speaking developers — a cultural and practical question relevant to international engineering teams. Acknowledged by name in the published edition.

Co-founder & Author
coderkids Snc
January 2015 - June 2017

Summary

Co-founded CoderKids.it, a programming education company teaching children to code using Scratch. Started informally in January 2015 under an existing company before formally incorporating in September 2015. Co-authored two books published and translated into multiple languages including Italian, French, English and others, written on commission from a publisher. Grew the operation to include 2 part-time employees and 8 contract collaborators before selling my share upon relocating to the UK in June 2017.

ML-Driven Responsible Gambling Platform at BetBuddy (Playtech)

Technical Lead
Playtech
May 2018 - August 2019

Summary

Led technical direction of Playtech's responsible gambling product, using machine learning and behavioural data to detect signs of problem gambling. Architected a key split of the monolithic application into two separate services — an ML batch processing component and a data presentation layer — significantly reducing infrastructure costs by right-sizing each service. Led development of the new client-facing interface and designed the data API. Hired and grew the engineering team, participated in client contract negotiations, and collaborated with stakeholders on strategy and delivery.
