André Figueira · Founder & principal engineer

One engineer, twenty-odd years of shipping software.

I'm André, the engineer behind Voidmode. This is the short version of how I got here, what got built along the way and what I tend to reach for.

The short version

I've been writing software professionally since 2003, back when PHP 4 was still a thing. Since then I've built and run production systems at enterprise scale, for ASDA, Tesco, Loblaws, Pizza Express and Harvester, and shipped my own products along the way. Voidmode is where all of that comes together.

The long version

Twenty-odd years, roughly in order.

  1. 2003

    First production code

    Professional work starts, back when PHP 4 was still a thing and most of the web was hand-rolled.

  2. 2006

    Voidmode starts

    Founded the consultancy, building specialised systems for businesses across all sorts of industries.

  3. 2012

    Agencies and startups

    Bespoke CMS work at MintTwist that got resold to client after client, then Holla@Me, a social network with big ambitions.

  4. 2013

    Lead engineer

    Agent Provocateur's platform, POS talking to warehouse in real time, and CI/CD before it was the default.

  5. 2014

    A platform from scratch

    Rebuilt Watchshop end to end, CMS, CRM, WMS, EPOS and Adyen payments, while keeping the old one alive.

  6. 2016

    Principal engineer

    Enterprise loyalty infrastructure for retailers like ASDA, Tesco and Loblaws. The eventing system I designed moves 7B+ events a year.

  7. 2022

    Trap Music Museum

    Custom ticketing and waivers that replaced a pile of expensive third-party tools.

  8. 2023

    mitchs.ai

    An AI that writes job ads in Mitch Sullivan's style. Revenue has gone up every month since launch.

  9. 2025

    Real-time 3D

    Velocity GP and Our Solar System, full games and simulations running in a browser tab.

  10. Now

    Not taking on new work

    Client work is paused for the moment, so the site stays up as a portfolio of what's been built so far.

How it works

How the work gets done.

  1. 01

    One person accountable.

    Every project here had me on it from the first conversation to production, designing the system, writing the code and making the calls.

  2. 02

    Small on purpose.

    A handful of projects at a time. It's the only way I've found to keep the quality high and stay close to the code.

  3. 03

    Senior help, when it helps.

    Bigger builds got more hands, senior engineers from my network who I've worked with for years and trust to ship.

Why it exists

“I started Voidmode Studios because I was tired of working in big teams where most time was spent in meetings instead of building. I wanted to work directly with clients and focus on shipping quality software. That's what I do.”
André FigueiraFounder, Voidmode Studios

For now

Strictly a portfolio, for now.

I'm not taking on client work right now, so this site is just here to show what's been built. The full portfolio has games you can play, products you can use and the stories behind the bigger systems.
