How I work

Built for distributed teams

A decade at international companies has made global collaboration second nature — I work daily with diverse teams across every time zone.

01

Remote-first for a decade

Deep work blocks, minimal meeting overhead, and a home setup built for focus — remote work is how I do my best work, not an adjustment to it.

02

Global by default

Comfortable collaborating with engineers, security teams, and stakeholders across US, European, and Asian time zones — async when possible, overlapping when it matters.

03

Async by default

Decisions in writing, status in shared channels, meetings reserved for what actually needs a conversation. Nobody gets blocked waiting on me.

04

Documentation as a deliverable

Runbooks, SOPs, and knowledge transfer baked into every project — so systems keep running and teams keep moving with or without me in the room.
