Stepping into manger role of frontend team after manager departures: ran agile ceremonies, coordinated across backend and product teams to help manage workloads, mentored teammates, and advocated for team priorities at director and VP levels.Handled all frontend and backend-for-frontend deployments for three months until new engineers could be brought on, and trained in same.Sole on-call engineer for potential front-end issues across all teams for three months, including several sub-hour debugging-to-resolution responses, including during mid-day, peak-usage outages.Rebuilding tech-debt-heavy, patient-safety-critical frontend services supporting Rx verification by pharmacists , including introducing e2e testing and improving unit testing to better-reflect business value and support fast and safe new-feature delivery.Wrote, tested, and shipped Python (Flask) code to immediately reduce server load on vendor image-fetching endpoint by 90% by setting appropriate HTTP client headers, replacing proposed multi-week S3 intermediate micro-service cache project with no net lines of code outside tests.Building fast and observable CI/CD pipelines, including automated development environments for AppSync graphql APIs and frontend web code to allow multiple engineers to concurrently test and iterate on features with internal stakeholders, without incurring merging/release costs.Being awarded as a company-level divvyHERO for outstanding work on the UI team, notably efforts to coordinate across engineering, pharmacy, and product teams to develop new features faster and more safely.

Built a low-code react app and backend system providing a point-and-click builder experience to make data-enabled react-native mobile apps at Y Combinator-backed company.Implemented reusable, accessible, type-safe react components in rescript and tailwind, including, e.g., fast drag-and-drop component tree, composable settings modal, and typeaheads.Collaborated with product and growth teams to prioritize, scope, estimate, and deliver new features across client and server, including: automated and robust PWA build and publish system, stackable actions, custom code, and global state management API for customer apps.Architected new client data-handling patterns that eliminated hundreds of lines of common data-fetching, handling, and caching logic out of react view components and into separate per-type modules, improving performance, and reducing bugs and feature development time.Reduced time to query core tree-structure with fully-joined entities for compilation from 4931ms -> 1124ms, massively improving UX and reducing server load and costs.Implemented dataloader pattern to improve backend graphql response times by >500ms for main builder screen initial load, reducing SQL queries from ~40 -> ~5 for same.Swept floors: answering customer questions, spiking projects, writing documentation, upstreaming fixes to open-source partner companies like Expo, and writing release notes.

One of three engineers working on serverless rebuild of real-estate investment manager back-office software linked to an investor-facing investment management and reporting portal.Designed, implemented, and released complex, client-driven multifactor authentication frontend in one-week sprint using XState powered state management and React hooks.Supported frontend work by troubleshooting and improving the backend, including graphql resolvers (Velocity), lambdas (Go/Node), and infrastructure specifications (Cloudformation).Debugged, fixed, and implemented future monitoring for an event-driven recursive lambda saving company massive daily AWS expenses.Implemented new core features in graphql middleware to support rapid product development, including filtering, deletion, and search resolvers.Designed and developed a graphql introspection-based form validation system, including a fixture-based testing harness for same, ensuring automatic runtime type safety while remaining flexible enough to handle field-specific validation functions.

Developed several cross-application frontend libraries, including a flexible and lightweight data grid library implemented in CSS Grid.
