Senior Software Engineer

I build frontend systems that stay reliable as products and teams grow.

7 years across early-stage startups and companies with millions in ARR, working in multidisciplinary teams from different cultures and countries.

What I do

  • Design systems

    Component libraries and tokens that keep product teams consistent without slowing them down.

  • Web apps

    Fast, accessible React and Next.js applications, covered by tests that catch what matters.

  • Full product lifecycle

    From the first question about the user's problem to shipping, measuring, and iterating.

Tools I work with

  • React
  • Next.js
  • TypeScript
  • Playwright
  • Jest
  • Node.js
  • Express
  • MongoDB
  • PostgreSQL
