About
Senior frontend engineer with nine years of experience building consumer and B2B products in React, TypeScript, and Next.js. Comfortable across design systems, accessibility, performance, and the long tail of browser quirks. Led the migration from a legacy monolith to a typed, componentized frontend. Looking for a Staff frontend role where the work compounds — not a maintainership.

Experience
Senior Frontend Engineer · Acme Platform
2021 — Present
- Built features in React, TypeScript, and GraphQL across the consumer platform — primarily checkout, onboarding, and the design system.
- Worked with design on components that the wider org ended up using, and helped keep the migration to a typed, componentized frontend moving.
Senior Frontend → Staff. Shipped the platform that three other squads now build on — and the rewrite that cut p95 by 38%.

About
Staff frontend engineer, nine years in, two promotions ahead of where my title says I am. The work I want to be measured on: turning an internal platform into a product ten teams build on, owning the rewrite that cut p95 from 1.4s to 870ms, and writing the design system the company finally treats as the canonical source. Currently shipping in React, TypeScript, and Next.js; comfortable with GraphQL, design-system ops, and the year-long rewrite that nobody else wanted to own. Open to Staff Frontend roles where the mandate is scope, scale, and the next hundred engineers — not a maintainership.

What changed
Headline reduced to a keyword list — no role, no verticals. About reads like the resume summary that already exists in the sidebar. Experience lists the stack instead of the shipped work.
What changed
Headline names the next role, the platform, and the metric. About opens with the role, not the title, and earns the comp-shape story in three lines. Experience lists the shipped-work outcome with a metric that survives the skim.
Names and companies anonymized. The rewrites are real engagements redacted for the page; specific comp movements depend on the brief, the candidate, and the market at the time of the search.
