Code and architecture audit
We assess code quality, security, performance, dependencies and documentation, and point out risks and priorities.
Custom software
Legacy system modernisation
We deliver legacy system modernisation without disrupting your business: code audits and architecture reviews, taking over application development from another vendor, database migration and step-by-step replacement with modern technology.
When a system needs modernising
Many companies run key processes on systems built over a decade ago. They work, but every change takes longer, technologies lose support, it is hard to find people who know the code, and integrating with new tools – including AI – is expensive or impossible.
Another common problem is losing vendor support: the company is left with a system with no documentation and no team able to develop it. Every outage becomes a business risk.
Modernisation does not have to mean rewriting everything from scratch. We usually propose a gradual approach: stabilise the system, carve out modules one by one and replace them with new ones, while the company keeps working as normal.
Warning signs
- Simple changes take weeks.
- The technology or database is no longer supported.
- No documentation and no one who knows the system.
- The vendor has ended the relationship.
- The system cannot be integrated with new tools.
Application takeover and migration – scope
We start with a thorough diagnosis and then plan the modernisation to minimise risk and cost.
Taking over application development
We take over maintenance and development from another vendor, rebuild documentation and tidy up environments.
Stabilisation and security
We fix critical bugs and vulnerabilities, update dependencies, and add monitoring and backups.
Database migration
We migrate data between database engines and versions (including PostgreSQL, MariaDB and MS SQL Server) with correctness checks.
Step-by-step module replacement
We carve features out into new modules and microservices, replacing the old system piece by piece.
Getting ready for AI
We expose data and functions via APIs so that the system can work with AI solutions.
How legacy modernisation works
Every stage ends with a working system – no risky “switch everything over at once”.
Free consultation
We learn about the system, its role in the company, known problems and expectations.
Audit
We analyse the code, architecture, database and infrastructure and prepare a report with recommendations.
Modernisation plan
We propose a strategy – stabilisation, migration or gradual replacement – with a schedule and staged quote.
Delivery in stages
We implement changes in sprints, with automated tests and the ability to roll back.
Maintenance and growth
After modernisation we provide maintenance, an SLA and ongoing development.
Technologies
Modernisation technologies
We modernise systems written in a range of technologies, migrating them to Java, Python, Node.js or modern PHP, with frontends in React or Angular. We work with PostgreSQL, MariaDB and MS SQL Server and run applications in containers with automated CI/CD.

- Python
- Node.js
- PHP
- React
- Angular
- PostgreSQL
- MariaDB
- MS SQL Server
- Docker
- Kubernetes
- SonarQube
- Playwright
- GitLab CI/CD

Example use case
Taking over and modernising a system from a previous vendor
A company uses an order management system built by a vendor that has ended the relationship. There is no documentation, the technology is outdated and every change risks an outage.
After a code audit we stabilise the system, update dependencies and add backups and monitoring. We then migrate the database to a current version and gradually move modules to a new API-based architecture. The company keeps working on a functioning system the whole time, and the new modules can work with AI solutions.

Frequently asked questions
Do you take over application development from another vendor?
Yes. We audit the code and architecture, rebuild documentation and take over maintenance and development of the system.
Does modernisation mean rewriting the system from scratch?
Not always. We usually recommend gradual modernisation, which reduces risk and lets the company work without downtime.
What does a code audit involve?
We analyse code quality, architecture, security, performance, dependencies and documentation. The result is a report with risks and recommendations.
Is database migration safe?
We plan migrations with backups, tests on a copy of the data and post-migration correctness checks, with the ability to roll back.
How long does legacy modernisation take?
It depends on the size and condition of the system. After the audit we prepare a schedule split into stages, each ending with a working system.
