Custom software development

Built at AI speed.
Reviewed by people who've done this for decades.

We're experienced software developers who use AI to design, write and test software far faster than a traditional team. Every change still goes through senior review, so you get the speed without the shortcuts.

src/invoices/sync.ts AI draft
-  const rows = await db.all(query)+  const rows = await db.all(query, { batch: 500 })+  for (const chunk of rows) {+    await syncInvoices(chunk, { retry: 3 })+  }

Senior review

Batching looks right. Added an idempotency key so a retry can't double-post an invoice.

Example of how AI-written code is checked and improved by an experienced developer before it ships.

How we work

AI does the heavy lifting. Experience makes the calls.

AI is a tool in our hands, not a replacement for judgement. Here's what a project looks like.

  1. 01

    Understand the problem

    We talk through your business, your users and what success looks like, then agree a scope and a first milestone.

  2. 02

    Build fast with AI

    Our developers use AI to draft code, tests and documentation, cutting the time spent on boilerplate and routine work.

  3. 03

    Senior review on every change

    An experienced developer checks architecture, security and edge cases before anything is merged. Nothing ships unread.

  4. 04

    Ship and support

    You see working software early and often. After launch we stay on to fix, improve and extend it.

About

Decades of experience, now with better tools

Avant Garde Software is led by a principal software developer with more than 20 years of experience designing, building and running production software.

That experience covers high-performance backend services processing data from millions of connected devices, payment platforms handling large transaction volumes, and software for healthcare, legal and child-safety organisations, where reliability and privacy aren't optional.

We've seen enough projects to know where software goes wrong: unclear requirements, rushed shortcuts and code nobody fully understands. AI lets us move much faster, and our experience makes sure that speed doesn't create those problems.
