We build the parts of software no one notices until they break.
Zhendao is a 34-person engineering studio that designs platform infrastructure, internal tooling, and reliability systems for teams whose outages make the news.
The name comes from a seismograph, not a slogan. Zhèn is the tremor — the load spike, the failed deploy, the 2 a.m. page. Dào is the path a well-built system draws through it: absorbed, logged, recovered, boring.
Founder Wéi Zhao started the studio in Shenzhen in 2019 after six years running infrastructure at a payments company that treated downtime as a marketing problem instead of an engineering one. Zhendao takes the opposite position: the interface is not the product. The thing underneath it is.
We're a studio of 34, split between Austin and Shenzhen, working with roughly nine clients at any given time. We turn away more projects than we take — mostly ones where the ask is a redesign and the actual problem is a database that can't hold the load.
What we actually get hired to fix
Platform engineering
Internal platforms that let product teams ship without filing a ticket to the infrastructure group. Golden paths, not gatekeeping.
Reliability engineering
SLOs that mean something, on-call rotations people can survive, and postmortems that change the system instead of assigning blame.
Data-path migrations
Moving a company off a database, queue, or monolith it has outgrown, without a weekend of downtime or a resume-generating event.
Developer tooling
CLIs, CI pipelines, and internal dashboards built for the fifty engineers who use them daily, not the one VP who sees the demo.
A few things we've shipped
How an engagement runs
Audit
Two weeks embedded with your team, reading logs and runbooks before we write a proposal, not after.
Scope
A written plan with the failure modes we're solving for named explicitly, so we're not graded on vibes.
Build
Weekly demos against a real environment. No slide decks standing in for working software.
Hand-off
Runbooks, recorded walkthroughs, and 60 days of on-call shadowing before we step back.
Who you'd actually work with
Wéi Zhao
Six years running payments infrastructure before starting Zhendao. Still writes code on client projects most weeks.
Priya Nandakumar
Led the Ledgerline migration end to end. Previously spent four years on a database internals team.
Tomás Ferreira
Runs client engagements and refuses to let scope creep in without a written change order.
