We're engineers first. Consultants second.
ZaStack was founded in 2019 on a simple premise: most software problems aren't technology problems, they're judgment problems. We bring the judgment and the hands to build it.
We work with founders shipping their first product and CTOs modernizing their tenth system — the discipline is the same either way.
ZaStack is remote-first — serving clients worldwide, made up of engineers who have shipped production software and AI systems inside startups, growth-stage companies, and large enterprises before working here.
We take on a small number of engagements at a time, by design. Every project gets senior attention from kickoff to handoff — not a rotating cast of juniors learning on your budget.

Four things we won't compromise on.
We say no before we say yes to everything.
Every engagement starts with a scope that protects your budget and our judgment. If something doesn't belong in the project, we'll tell you before it becomes a line item.
We build systems we'd be comfortable running.
Code is judged by what happens after launch — monitoring, incidents, onboarding a new engineer. We build for that day, not just for demo day.
You see progress the same way we do.
No black-box updates. You get access to the same repos, boards, and metrics we use internally, from kickoff to handoff.
The goal is to make ourselves replaceable.
Documentation, runbooks, and knowledge transfer aren't an afterthought — they're a deliverable, so your team can operate independently when we're done.
