Some of the bigger things I've worked on:

• Took our background actions project from 50 to 100%, with a focus on correctness (introducing idempotency into our retryable bits) and infrastructure (booting up a new temporal cluster).
• Created an automated, zero-downtime migration for moving customers between database storage strategies.
• Migrated our monorepo from yarn to pnpm.
• Swapped out Monaco for CodeMirror, along with creating our own language server and LSP client to provide autocompletion, diagnostics, and all the things you'd expect out of an advanced editor.
• Load testing scenarios using Grafana's k6
• Added a scheduling trigger for Gadget actions (basically, cron jobs).
• Added real-time streaming to our log viewer.
• Migrated us from one database provider to another with no data loss and within our 30 minute maintenance window.
• A steward of the platform and codebase. That meant ensuring the platform was kept up and running, and that the codebase was kept up to date and organized according to our principles.
• User-defined HTTP routes for Gadget apps (comparable to AWS Lambda).
• Created a library  providing typesafe React bindings for Gadget (lots of advanced TypeScript).
• Initial implementation of @gadgetinc/mobx-quick-tree  (reduced node event loop blocks).
• V1 of our Shopify connection (managed syncing, webhooks, and oauth for Shopify apps).
• Designed and implemented a planner (topographical sort) for Gadget's nested actions.

Less technical things I'm involved with:

• Sharing my knowledge and context of the system to help accelerate all members of our team.
• Lots of informal mentoring via pairing, code review, and internal conversations.
• Interviewing candidates to assess technical skill (and a small amount of sourcing).

• Helped build and influence the design of packwerk , an open-source tool for enforcing boundaries in Ruby/Rails codebases.
• Building tools, patterns, and educational materials to enforce software architectural boundaries on Ruby/Rails projects.
• Designed and built an intra- and inter-cluster eBPF-based ping mesh for network observability in our Kubernetes platform. Required digging into the TCP stack implementation of linux (bootlin  helped a lot for easy source code navigation)
• Built a data pipeline to isolate performance regressions in the Shopify platform.
• Continued to help build our organization with regular interviews (~1 per week).

• Designed and helped develop Fraud Protect for Shopify Payments (a warranty system for protecting Shopify merchants against fraudulent chargebacks).
• Designed and helped implement a new model for expressing order risk (known as "risk assessments").
• Started interviewing on a regular basis for the R&D organization, primarily pair programming.

• Designed an approach for asynchronous label purchasing.
• Created a regional failover setup for our shipping service (using AWS Route 53).
• Automated our shipping service's infrastructure with Terraform.
• Moved our shipping service from classic EC2 to VPC EC2 with zero downtime.
• Improved performance of our shipping rates/label service through profiling.

• Created new and expanded existing test infrastructure (e.g, static analysis, automated HTML validation, creating and validating test seams for functions with complex responses).
• Move the local development environments to the cloud, with a service that had pre-warmed environments and leasing capabilities.
• Improved the stack by dependency refactoring, reducing build times, build size, and resource consumption.
• Expanded YouTube's primary local development environment with new functionality, also building out new service fakes to improve boot time.

• Focus on computer vision
• Graduated with a 3.8 GPA.
• Awarded an NSERC Graduate Scholarships 
• Thesis: Underwater Stereo Matching and its Calibration 

• Graduated with a 4.0 GPA and first-class honours.
• Dean's list recipient all years.
• Awarded the "University Medal for Academic Excellence" in both Mathematics and Computer Science.
• Led my ICPC programming competition  team to the northeast North American regional twice.
• Thesis: Automatic Panorama Construction: An In-Depth Look into Image Stitching
