## Work

Selected work. Teams that shipped faster. https://leanrob.com/#work

- **Jobber**, Senior Software Engineer (2025–2026, current): AI tooling that helps developers ship with less friction. Built GraphQL guardrails that catch dangerous schema changes at every stage of development (local work, AI-steered changes, commits and pull requests), improved the application deployment pipeline, created AI tooling for custom development workflows, and built an artifact proxy that protects against compromised packages. Tags: React, Ruby on Rails, GraphQL, Node.js, TypeScript, AWS, Docker, AI tooling.
- **Getty Images**, Senior Software Engineer: Building an AI image platform on a world-class library. Developed and deployed features across Getty and iStock's multi-site architecture; migrated legacy features to a modern React and NestJS layered architecture following team-defined ADRs, spanning Ruby on Rails, Angular and the new stack; strengthened testing coverage and CI reliability; coached teammates on AI prompting, tool integration and workflow automation. Tags: React, Next.js, Ruby on Rails, Angular, NestJS, Jest, GitLab, Copilot.
- **Shopify**, Intermediate Software Engineer: Faster dev loops for the Point of Sale mobile team. Full-stack development in React Native, GraphQL and Rails; led projects from inception to deployment; built the end-to-end testing platform that runs tests on real devices, captures run videos, suggests fixes on failure and retries automatically; improved retail mobile speed and resolved complex stability issues. Tags: React Native, GraphQL, Ruby on Rails, Redux, Appium, BrowserStack.
- **Arc'teryx**, Senior Software Engineer: A sharper storefront and a single front door for sign-in. Led a major navigation redesign across multiple teams; ran high-priority identification system migrations; built scalable solutions with React, Next.js and AWS (CloudFront, S3, SST) plus Auth0; created mission control environments that kept critical issues moving to fast resolution. Tags: React, Next.js, Node.js, AWS, CloudFront, S3, SST, Auth0.
- **Finhaven**, Founding engineer: A Rust trading platform, built and handed over. An event-sourced, event-driven system using domain-driven design and CQRS, with an immutable record of every transaction; both sides of each trade encrypted with elliptic-curve cryptography (secp256k1 keys). Shipped and approved by the BC Securities Commission. Tags: Rust, React, Python, Trading, Financial Tech, DDD, CQRS, Event Sourcing.

## Stack

"Things I've built with…": pick a stack, read the code, see what it shipped. https://leanrob.com/#stack. Sample code and motion in this section are illustrative demos, not production source or telemetry.

- **React Native**, fast, reliable checkout: a checkout that never drops a sale. Cart and checkout screens, barcode scanning on iOS and Android, offline sales that sync later. (React Native, TypeScript, iOS, Android)
- **GraphQL**, safer API changes: an API that changes without breaking apps. Automatic change checks, a retirement dashboard, clear feedback on changes. (GraphQL, TypeScript, CI)
- **Ruby on Rails**, dependable builds: package installs you can count on. Private package source, approved-package list, faster repeat installs. (Rails, Ruby, RSpec)
- **Rust**, accurate money movement: money that is always accounted for. Account ledger, settlement, extensive automated tests. (Rust, Postgres)
- **TypeScript**, fast web pages: boards that teams actually share. Create, share and comment on boards, related-image suggestions, a shared look across apps. (Next.js, TypeScript, React)
- **AI tooling**, safe coding help: AI help without losing control. Coding assistant, step-by-step history, bulk code-change tools. (TypeScript, LLMs)
