Dario Sanchez Design Engineer

Senior design engineer and systems thinker with 8 years of full-stack experience, most of it leading frontend architecture, UX, and design on teams of 3–6 engineers. Physics B.A. from UCLA.

I care about UX in a broad sense that accounts for the entire stack and any aspect of human-computer interaction. Beyond aesthetics, this includes facets like performance and general software quality (bug count). This interest extends to improving efficiency within engineering team processes, such as coming up with more ergonomic ways of coding with LLMs within a team, and refactoring away longstanding bottlenecks to speed up our output.

Sometimes I build physics projects with friends, like a Tesla coil and an X-ray machine.

Experience

Jan 2023 – Present

Major, Lindsey & Africa

Senior Software Engineer

  • Lead frontend, UX, and design authority following MLA's acquisition of Hire an Esquire. Ship and maintain two legal recruiting platforms across the full stack.
  • Top GitHub contributor in the project's history. Spearheaded several major refactors and modernization initiatives.
  • Onboarded and mentored two more engineers after the acquisition; interviewed engineering candidates.

Aug 2018 – Dec 2022

Hire an Esquire(acquired)

Senior Software Engineer & Designer

  • Main frontend engineer and sole design authority on a 3–4 person engineering and product team. Built most of the frontend from the ground up and worked directly with leadership on technical and product direction.
  • Proposed and led TypeScript adoption across the entire codebase, shifting the team from constant bug-firefighting to consistent feature delivery.
  • Led a large migration to RTK Query, replacing an ad-hoc data-fetching layer that had become a bottleneck.
  • Mentor for two engineers, both now senior at MLA.

Projects

UXSpice

UXSpice

A new circuit simulator. Circuit simulators are famously cumbersome. They don't have to be, so my goal is to raise the bar for speed, design, and overall user experience without trading one for another. Built with Svelte, WebGPU, and ngspice, each picked for performance. Svelte compiles away, WebGPU draws straight to the GPU, and ngspice compiles to WASM and runs in a Web Worker. I built the UI library from scratch for maximum customization.

Education

University of California, Los Angeles (UCLA)

Physics, Bachelor of Arts, 2014 – 2017

A broad education in physics, philosophy, mathematics, and computer science, across both the sciences and the humanities.

Tools That Inspire Me

  • Linear

    For treating design, speed, and UX details as core features.

  • Base UI

    For being the best take on headless components that currently exists.

  • U.S. Graphics

    For taking the opposite aesthetic position from Linear and being just as right.

  • Paper

    For raising the bar on design tools in a market most consider settled.
