Who we are

An engineering studio, not an agency

Build · Optimize · Deliver

ZeroLag IT is a new studio, started by engineers who spent their careers building large-scale mobile applications and full-stack web platforms inside other people's companies. The name is the promise: no lag between a problem being understood and it being fixed.

We are deliberately small and deliberately senior. The engineer who scopes your project is the one who writes the code, you get a release every fortnight rather than a status report, and the source, documentation and cloud accounts are yours throughout — not at the end, if you ask nicely.

We take on work we know how to do well. If your problem sits outside that, we will tell you on the first call rather than learn it on your budget.

  • Named engineers, no rotation mid-project
  • A working release every fortnight from week three
  • Full source, documentation and infrastructure in your name
  • Fixed team and rate, capacity-based rather than fixed-scope

Named engineers, start to finish

The people who scope your project are the people who write the code. No handover to a junior pool.

Working software every fortnight

A release you can open and use from week three, not a status report and a demo at the end.

Your code, your infrastructure

Full source, documentation and cloud accounts in your name from day one, handed over whenever you ask.

How we work

From first call to production in weeks

No discovery phase that bills for three months and produces a slide deck. You see running software in the third week.

1
Scope

A week of workshops that ends with a written technical scope, a fixed team and a first-release date you can hold us to.

2
Design

Interactive prototypes and a design system before a line of production code, tested with your actual users.

3
Build

Fortnightly releases into a staging environment you can use, with a demo at the end of every sprint.

4
Launch

Load-tested, penetration-tested and rolled out in cohorts, with rollback rehearsed before it is ever needed.

5
Run

Monitoring, on-call and a quarterly roadmap. Or a clean handover with full source and documentation.

How we build it

The stack behind the work

Chosen per project, not per fashion. These are the tools we build with day to day, and the ones we will argue for or against on your first call.

Tell us what you are trying to build

A 45-minute call with the engineers who would do the work, not a salesperson. You leave with a rough scope and an honest view on whether we are the right fit.
