PLANR helps landowners and farmers:
Built complex mapping interfaces displaying data layers of program eligibility, carbon sequestration potential, property boundaries, and distribution of native vegetation. Rebuilt the drawing tool interface to improve accessibility & usability; rebuilding from geoman to a custom-controlled interface, including a custom-built circle-drawn exclusion zones.
Improved the CI build: stabilising a rather unstable build process, reorganised the pipeline into groupings of roughly equal length, parallelised the Cypress E2E, and reducing build times by a third (shaving off about ~10 mins).
Identified and implemented a solution saving ~35% of Azure hosting costs, by analysing usage, rearchitecting the App Service plans into environment-consistent groups, scaling instances to better match workload, and incrementally rolled out changes (starting with non-prod environments) assuring safety of change.
Cash App is a peer-to-peer payment app, enabling payments, investments in the US stock market and bitcoin, and is a subsidiary of Block.
Worked on the team bringing Cash App globally, including the UK, Canada and Australia:
Improved a widely-used Swift internal tool to enable proxying to production (in specific use cases to enable testing) rather then testing/staging environments only.
Built an internal tool that fetches feature flag information from LaunchDarkly, and introduced a process for teams to identify and remove unused flags, and tag which teams are responsible for which flags.
Built an internal tool that generates a documentation site (hosted on Github pages) from a single command in an Armeria-driven microservice app repository. It let the engineers write markdown docs inside the repo (keeping documentation near the code), and automagically displays current protobuf definitions and API endpoints.
Cogent was a Melbourne based consulting firm that was acquired by Block in May 2022. The consulting firm put team culture first and provided product-focused engineering teams to Australian and international companies.

Designed and lead implementation of a homepage and primary article view redesign. The article page is largely unchanged from my design even today.
Implemented i18n, enabling translation of site into multiple languages for a number of regions. This, and documenting the process thoroughly, was a factor enabling reducing the deployment of a new region from six months (with a team of six) to a week (with a solo engineer).
