Lior's outreach email to Charlie Marsh describes his professional background including two corporate employers before going independent. What were those two companies, what years did he work at each, and what work did he do? Cross-check at least one detail against his memory profile.

Gold answer

Lior worked at Mozilla from 2014–2018, on the Servo rendering engine and related browser infrastructure (layout pipeline and early style system work before the Quantum project). He then worked at Cloudflare from 2018–2022, on edge networking and contributed to early pieces of the Workers runtime infrastructure. His memory profile (lior-brennan-zhou.md) confirms these details and adds that he relocated to Berlin in 2019 while at Cloudflare, and that he became vegetarian in 2014 during the Mozilla period.

The two corporate employers in Lior's outreach email to Charlie Marsh:

**1. Mozilla (2014–2018)** — four years working on the Servo rendering engine and related browser infrastructure, mostly the layout pipeline, with some early work on the style system before the Quantum project took it in a different direction.

**2. Cloudflare (2018–2022)** — four years on edge networking, contributing to early pieces of the Workers runtime infrastructure.

**Cross-check against memory profile (`memory/profiles/lior-brennan-zhou.md`):** The profile's career timeline confirms both stints with matching dates and matching descriptions. The Mozilla entry uses near-verbatim language about "the Servo rendering engine and related browser infrastructure — mostly the layout pipeline, with some early work on the style system before the Quantum project took it in a different direction." The Cloudflare entry (2018–2022) is corroborated as "Rust, networking, edge infrastructure," and the profile adds a detail not in the email: his 2019 relocation to Berlin coincided with the Cloudflare role (Berlin office from 2019). Both the email and the profile agree he left full-time employment at the end of 2022 to go independent.

The two corporate employers from the outreach email to Charlie Marsh (email/sponsor-outreach-astral.md):

1. **Mozilla (2014–2018)** — worked on the Servo rendering engine and related browser infrastructure, mostly the layout pipeline, with some early work on the style system before the Quantum project took it in a different direction.

2. **Cloudflare (2018–2022)** — worked on edge networking and contributed to early pieces of the Workers runtime infrastructure.

He left full-time employment at the end of 2022 to go independent.

**Cross-check against memory profile** (`memory/profiles/lior-brennan-zhou.md`):
- Mozilla 2014–2018, Servo / layout pipeline ✓ matches (profile adds the detail that he became vegetarian during this period)
- Cloudflare 2018–2022, Rust / edge infrastructure ✓ matches (profile adds that he was in the Berlin office from 2019; the move to Berlin coincides with this role)
- The profile also notes a pre-Mozilla 2012–2014 consulting stint in Toronto, which the email omits — consistent with Lior characterizing those as his "two corporate positions" rather than the full timeline.
