Memo Rebolledo
Senior Frontend Engineer
I build accessible, scalable, and performant applications for the web.
Hello there 👋 I am a Senior Frontend Engineer specializing in accessible UI, design systems, and performance. I work closely with design and product teams to ship polished web experiences that scale.
- Accessible UI at scale: WCAG-driven improvements, a11y audits and remediation, accessible component primitives and interaction patterns
- UI architecture & systems: component APIs, shared patterns, design systems, complex state and data-heavy UI
- Performance & quality: profiling, Lighthouse/Web Vitals mindset, rendering and bundling optimizations, regression prevention
- Data-informed UX: dashboards and journey telemetry to find friction and drive quality-of-life improvements
Experience
Senior Frontend Engineer · Cerby
- Led accessibility work across key product flows (account onboarding, secrets/notes onboarding, collections), aligning experiences to WCAG practices and removing adoption blockers for enterprise customers with thousands of users.
- Owned and evolved Cerberus design system used across Web, Extension, and Mobile: built accessible primitives (dropdowns, collapsibles, toggles, checkboxes) and complex UI (data tables), reduced duplicate components, and lowered UI bug volume through shared standards and close design collaboration.
- Frontend lead (team of 4) for a password manager migration tool delivered over 4–6 months: owned research, architecture, implementation, and QA; launched with LastPass and expanded to 1Password and Dashlane to support customers in the tens of thousands of users range.
- Improved confidence in releases by adding unit and integration test coverage across key web flows, helping catch regressions earlier and making refactors safer. Also helping the QA automate several end-to-end tests.
Senior Software Engineer · Wizeline
- Dow Jones / Wall Street Journal: Refactored newsletter UI into reusable React components, improving delivery velocity and reliability for a platform serving 3M+ subscribers.
- Led 5+ engineers building a Slack-integrated employee recognition product (Node.js, React, PostgreSQL, GitHub Actions), used by hundreds–thousands daily and embedded into onboarding and culture.
- Golden State Warriors / Chase Center: built and maintained suite rental platform (Next.js, GraphQL, GCP), improving SSR stability and mobile responsiveness.
Fullstack Engineer · Universidad de Guanajuato
- Built a job placement platform used by hundreds of graduating students & partner companies.
