I build the parts of a system that are not allowed to be wrong.

Technical lead on NextGen, a visual collaboration platform for enterprise Agile and operational management. I own the time-series and KPI services — aggregation, consolidation, and frequency models that all have to agree with each other — and stay close enough to DevOps to answer for what happens after the merge, not just what happened before it.

An airline financial-reconciliation platform, architected from scratch: ETL, matching and featurisation engines, KPI components consumed across the business. Also Scrum Master for the team — protecting its ability to finish things, and coaching juniors on clean code and testing discipline.

A configurator of business processes for marketplaces, built on top of workflow engines, with processes deployed dynamically into AWS sandboxes. Led the migration to microservices and publish/subscribe across feature teams, and wrote the Gatling scripts that found where it fell over before a customer did.

Brainstorming and animation features, an ACL security model applied at every level of the platform, and an in-house CQRS and event-sourcing implementation once the read side stopped keeping up. Proofs of concept for paths nobody had explored yet, and third-party integrations such as Jira.

Core platform modules, and the production incidents of everyone running them: diagnosis, fixes, automated tests to keep the same regression from coming back, and performance work alongside product and QA.
