Joined Swirrl IT Ltd in 2019; continued in the role following acquisition by TPXimpact in 2022. Joined as a Senior Software Engineer and progressed to Principal Software Engineer.
Worked across web, geospatial, and linked-data systems using JavaScript/React, Java/Clojure backends, Clojure/Python data processing and ETL, SPARQL/RDF graph databases, PostgreSQL/PostGIS, AWS, Google Cloud, shapefiles, and Mapbox Vector Tiles.
Contributed to Swirrl’s core infrastructure, improving reliability and operational maturity across cloud-hosted data platforms, including architectural decisions and deployment automation for business-critical services.
Lead Engineer for a long-running programme with the Environment Agency, providing technical ownership across multiple concurrent projects spanning product development and site reliability.
- Architectural oversight and engineering direction for several production systems.
- Led reliability and operational improvements for public-facing data services.
- Rewrote the Catchment Data Explorer to modernise its architecture and improve maintainability and performance.
- Took the Shoreline Management Plan platform from prototype through to full production.
- Worked closely with client stakeholders to translate complex environmental and policy requirements into robust, production-grade systems.
Worked primarily on backend systems and a mortgage broker portal using Haskell and PureScript, building and maintaining robust, type-safe services and user-facing functionality. Focused on improving system reliability and correctness within a functional programming paradigm.
A key achievement was diagnosing and resolving a complex, deep-seated bug in the Haskell/PostgreSQL event sourcing persistence layer, restoring data consistency and improving the stability and integrity of the platform’s broker/customer data workflows.
GoMore is a peer-to-peer transportation startup based in Copenhagen.
Led infrastructure projects as part of the backend team, built Clojure APIs and worked on the Rails website as part of the broader product team.
Moved the product from Elastic Beanstalk to containers and migrated the main database load to Aurora, improving scalability and cost efficiency.
