Legacy software modernization
We migrate systems that keep the company running but block change: old applications, macros, unmaintained databases, manual processes and single-person dependencies.

Frequently asked questions
Fixed price or phased? We clarify it after reviewing scope, risks and integrations. We prefer small phases with verifiable deliverables.
What do you need to start? Context, goal, current systems and one decision owner.
How we approach it
We treat legacy software modernization as serious engineering: clear scope, justified technical decisions and reviewable deliveries. We prioritise what brings business value and avoid the over-engineering that inflates cost and timeline with no benefit.
- Architecture suited to the problem, with no unnecessary complexity.
- Maintainable code, with tests on the critical parts and useful documentation.
- Well-designed integrations and APIs that grow without a rewrite.
- Reliable deployment and post-launch support as you need it.
We work in phases with reviewable milestones, so you always know what is delivered, when and why, and can adjust priorities without budget surprises.
More frequently asked questions
Do you work fixed-price or hourly? Fixed price when scope is stable; time and materials when there's discovery or frequent change. We make it clear in the proposal.
Is the code mine? Yes. We hand over the source code and documentation; we don't lock you into a black box only we can touch.
What happens after launch? We can agree corrective support, evolutionary improvements or a monthly hours pack depending on the pace of change and criticality.
