I am decisively steering Diamond away from legacy systems and championing the integration of new technologies that are positioning us at the forefront of our industry.My team is building tooling to support sales and operations. This involves the development of internal apps, syncing with our CRM, and generally helping data flow from marketing all the way to job completion. Our tools facilitate mapping, estimation, costing, contracts, sourcing, scheduling, and oversight management. We are eliminating bottlenecks, increasing quality, and scaling our sales and ops teams!Highlights* Building with React, Remix, TypeScript, gRPC/Protobuf.* Creating a CI/CD pipeline via GitHub, Docker, GCP, Kubernetes, ArgoCD.* Building apps with performance in mind (e.g. redis cache, server-side rendering).* Instrumenting apps with observability via OpenTelemetry, feeding into Jaeger, Prometheus, and Grafana.* Securing internal apps with OpenID Connect and implementing role-based access.* Establishing the foundation of a Diamond software engineering program, including developing a level/competency matrix, designing an interview process/question bank, and documenting a software development process (e.g., RFCs).* Mentoring engineers through code review, assisting in RFC authoring, and guiding in goal setting.

Spent years in Uber's Marketplace organization working on technology driving real time optimal Driver positioning, incentives, and data processing pipelines. Helped launched multiple evolutions of pricing systems, built mobile frameworks that reduced multi-week rollouts to < 1-day via backend driven UIs. Developed frameworks to power both in-app pricing features and driver dispatch (e.g. job offers). I also spent time collaborating across all of our high level teams to unify in-app multi-platform tooling across all of Uber's mobile apps (rider, driver, eats, freight, air).Highlights* Built the first iteration of hex-based surge rendering on Android. Later evolved this from raster-based tiling to vector rendering, reducing network payloads to ~5% of their original size.* Worked relentlessly to minimize memory pressure from the Bitmap hungry map rendering. Migrated to stream processing, which greatly reduced memory consumption in our map processing pipeline.* Designed the system for Uber's first cohesive Driver Dispatch experience, combining 3+ separate job offer code paths into a single, highly flexible system where job rendering decisions could be tuned via backend decision making.* Worked with our Observability/SRE team to build config-powered grafana dashboards and corresponding monitoring queries. The established patterns were adopted by many other teams!
