Our Competencies

After this many years in the trade, there isn't much of the stack we haven't shipped: frontend, backend, mobile, cloud. High-load systems, legacy rescues, greenfield builds. Pick a technology below. Odds are we've taken it to production more than once:

Backend Development

  • PHP, WordPress
  • Python, Django
  • NodeJS
  • Big Data & High Load

Machine Learning & AI

  • AI Integrations
  • Chatbots, Agents & RAG
  • Analytics & Tracking
AI Development services →

Frontend Development

  • ReactJS, NextJS, VueJS
  • JavaScript (JS)

Mobile Development

  • React Native

Cloud & DevOps

  • Google Cloud, AWS

What We Offer

Software development services across the whole lifecycle — from the first prototype to production at scale:

Full Cycle Development

We handle every aspect of your project, from idea to launch. We can also take over existing projects.

MVP Development for startups →

Prototyping & Design

Clickable prototypes in days, clean production UI after — you see the product before you pay for the full build.

MVP Development →

Backend & Frontend Development

Backends that stay up under load, and interfaces nobody needs a manual for.

Web Development services →

DevOps & Maintenance

We keep production boring: monitoring, CI/CD, backups — and someone who answers when it matters.

DevOps & Cloud services →

Mobile Development

iOS and Android from one React Native codebase — we've taken apps through both stores plenty of times.

Mobile App Development →

Architectural Solutions

Architecture advice from people who've paid for the wrong decisions — so you don't have to.

Architecture Reviews →

Improvements, Optimisations, & Scale

When traffic grows and the app groans, we find the actual bottleneck and fix it — measured, not guessed.

Performance & Scaling →

Consulting

Straight answers on architecture, AI, and build-vs-buy — from engineers, not salespeople.

Consulting & Audits →

API Development

APIs your partners can build on: documented, versioned, and tested against real-world abuse.

APIs & Integrations →

We put AI into products and operations where it actually pays — it's daily work for us, not a lab experiment.

From first sketch to a product holding real traffic — we've scaled systems for brands you'd recognize.

Fintech, e-commerce, automotive, media — after this many years, your domain probably isn't new to us.

Two-person startups and household-name corporations get the same deal: straight talk and working software.
