What we do

Services & expertise

A full-stack, end-to-end capability — one accountable company covering analysis, architecture, development and operations. Whatever needs to be engineered, we deliver it.

Software Architecture & Development

End-to-end design and development of custom applications, APIs and platforms — from the first sketch to a production system you can rely on.

DevOps, CI/CD & Cloud

Automated pipelines, containers and cloud infrastructure that let you ship faster, deploy safely and stay reliable under load.

IT Consulting & Solution Design

Independent analysis, architecture and technology strategy — so you make the right call before a single line of code is written.

Legacy Modernization

Re-thinking and re-designing outdated systems into maintainable, scalable solutions — evolving your stack without the rewrite chaos.

AI-Powered Development

We build real products faster by putting modern AI to work across the whole development lifecycle — from design to delivery.

In R&D

AI for Healthcare — ECG

An emerging focus: training deep-learning models for ECG signal analysis, bringing modern AI to medical diagnostics.

In R&D

AI on Edge Devices

Intelligence at the edge — fast, private, always available. We bring AI models out of the cloud and onto the devices themselves: smartphones, embedded accelerators and industrial hardware alike.

Why ADUNET

One senior company is worth more — and more cost-effective — than a big team without the skills.

A wide range of real-world experience across many projects and domains.

Deep knowledge of how and why things actually work.

Time-saving tooling and practices that keep delivery genuinely efficient.

Arguments made concisely and factually, not by opinion.

Thinking out of the box to find solutions others miss.

A mindset built to achieve real product quality, not just “done”.

Clear judgement between what’s important and what’s merely urgent.

Effective use of CI/CD — continuous integration and delivery.

One accountable partner covering analysis, architecture, development and DevOps.

Able to lead and teach, and set the rules that drive desired quality.
