Engineering & Modernization

Make existing software faster, cleaner and easier to evolve.

Software that works but fights every change is expensive in a quiet way: features take longer, bugs return, and good developers leave. We work on existing codebases. We find what is slowing them down, fix the parts that matter in an order that makes commercial sense, and can stay on as the engineering team that keeps them healthy.

You might be here because

  • Pages that used to load instantly now take seconds as data has grown.
  • Every release breaks something unrelated.
  • The original developer has left and nobody fully understands the system.
  • Your in-house team is at capacity and the backlog keeps growing.

Software modernization, technical audits and ongoing engineering

Technical audits
A written assessment of code, architecture, infrastructure and risk.
Architecture review
Whether the current design can carry the next stage of the business.
Backend optimization
Slow endpoints, heavy jobs and wasteful resource use found and fixed.
Database optimization
Queries, indexes and schema reworked for the data volume you have now.
Technical debt
The debt that costs you most, paid down in planned increments.
Legacy modernization
Old frameworks and unsupported versions replaced without a risky rewrite.
Cloud modernization
Containerised, reproducible deployments on AWS or Azure.
Application performance
Measured improvements to load time and responsiveness.
Reliability and scaling
Monitoring, alerting, backups and capacity for growth.
Ongoing engineering
A standing team for features, fixes and maintenance each month.

What this looks like in practice

An audit before a rebuild decision

Before committing to a rewrite, a business asks for an independent view of what is salvageable. Often most of it is.

A slow report traced to three queries

Performance problems usually have a small number of causes. We measure first, then fix those.

Extra capacity for a stretched team

We take a defined part of the roadmap and work in your repository, your process and your review flow.

How we approach it

  • We measure before changing anything, so improvements can be shown.
  • Fixes are prioritised by business impact, not by what is most interesting.
  • Changes ship in small steps behind tests, not as a big-bang rewrite.
  • We say when something should be left alone.

A defined way to start

For businesses with existing software

Engineering Audit

An independent review of your codebase and infrastructure, ending in a roadmap ordered by what will help most.

  • Architecture review
  • Codebase assessment
  • Performance review
  • Database review
  • Technical risks
  • Prioritized roadmap

Legacy application modernization without a rewrite

A full rewrite is the most expensive option and the one most likely to fail: the old system keeps changing while the new one chases it. Most legacy applications can be modernised in place.

We replace one part at a time behind a stable interface, starting with whatever causes the most pain. The system stays in production throughout, and each step can be stopped or reversed.

Technical debt consulting: what to pay down first

Not all technical debt is worth repaying. Ugly code that nobody touches costs nothing. Fragile code in the part of the system you change every week costs you on every release.

We map debt against how often each area changes and how badly it fails, then give you an ordered list with estimates. You decide how much to take on each quarter.

When to modernise, and when to leave it alone

Modernise when an unsupported framework has become a security risk, when adding a feature takes weeks that should take days, when hosting costs are out of proportion, or when nobody can be hired to work on the stack.

Leave it alone when it works, rarely changes and is not exposed. We say so when that is our finding.

Questions about engineering & modernization

What do we get from a technical audit?
A written report covering architecture, code quality, performance, database, security and infrastructure, with risks ranked by impact and a prioritised roadmap. It is written to be read by a non-technical decision-maker as well as a developer.
Should we rewrite or modernise?
Usually modernise. A rewrite is justified when the platform itself is the obstacle, for example a language or framework that is no longer supported. An audit answers the question with evidence.
Can you work alongside our in-house developers?
Yes. We take a defined part of the roadmap and work through your repository, your pull-request reviews and your release process.
Our application has become slow. Where do you start?
By measuring. We add tracing to find where time is actually spent, which is nearly always a handful of queries or endpoints, and fix those first.
Do you offer ongoing maintenance?
Yes, on a monthly basis: fixes, dependency and security updates, monitoring and small improvements.
