Mattia Asti

Software Engineer

I'm a software engineer with over 14 years of experience, currently based in London, UK. I work best with TypeScript across the full stack while specializing in the frontend, where I've been using React for years. These days, a lot of my work is AI-assisted, and I've used Claude Code heavily over the past year. I'm the type of engineer who thrives at the intersection of product and code; I genuinely enjoy talking to users, understanding their problems, and shaping solutions that address real needs. I'm a big fan of home automation and love finding new ways to use my collection of Raspberry Pis.


Staff Software Engineer - Apple May 2022 - Present

I'm part of Apple Services Engineering where I work on internal tooling allowing us to scale our localization across 175 countries and over 50 languages.

  • Replaced an opaque AI black box with an agentic editorial workflow users can see and steer at every step.
  • Built a remote caching service in Rust used by 20+ teams. Saved 6k hours/year in compute and engineering.
  • Cut analytics feature delivery from 3 months to 2 weeks by applying AI across the whole workflow: design and process, not just code.
  • Cut CI from 30 minutes to ~3 across a 9-app monorepo with state-of-the-art tooling.
  • Organized high-profile community events with engineering directors, including an EMEA frontend conference and a talk with the creator of Bun.
  • Act as a technical multiplier across the org: my internal React guides are the go-to standard and engineers of all seniority levels rely on my reviews and advice.
  • Authored company-wide shared libraries; my internal Playwright Docker image has 100k+ downloads.
  • Pioneered identity attestation and mTLS-based internal auth; my guide and example repo became the go-to reference for frontend engineers.
