Legacy App Dockerisation
Containerised a legacy app so it runs identically everywhere, from laptop to prod.
Overview
Containerised a legacy app so it runs identically everywhere, from laptop to prod. I containerised the app and its services with Docker and Compose, standardising local, staging and production so it runs identically everywhere and new devs are productive in minutes. Built with Docker, Docker Compose, Nginx, this devops & cloud project was delivered for a client in Worldwide and designed for reliability, a clean user experience and long-term maintainability — so it keeps delivering value well after launch.
The challenge
A legacy app was a nightmare to set up — 'works on my machine' bugs and painful onboarding.
What I built
I containerised the app and its services with Docker and Compose, standardising local, staging and production so it runs identically everywhere and new devs are productive in minutes.

Plan & design
A clear scope, architecture and milestone plan, so you know exactly what's being built and when.
Build & iterate
Development in reviewable increments with regular updates, so you see working software early and often.
Launch & support
Testing, deployment and ongoing support, so it keeps running smoothly long after go-live.
Legacy App Dockerisation — FAQ
Can you build a legacy app dockerisation for my business?
Yes. I build custom devops & cloud solutions like this legacy app dockerisation, using Docker, Docker Compose, Nginx and tailored to your exact workflow, timeline and budget. Send me your requirements and I'll reply with a clear plan and quote.
How much does a project like this cost?
It depends on scope. After a short discovery call I provide a clear, fixed quote and milestone plan before any work begins — no surprises. Smaller builds start low; larger platforms are quoted per milestone.
How long does it take to build?
A focused MVP can take a few weeks, while a larger devops & cloud build runs in milestones over a couple of months. You'll see working software early and often, not just at the end.
What technology do you use, and will I own it?
This project uses Docker, Docker Compose, Nginx. I pick the right stack for each project, and you own 100% of the code and infrastructure — delivered in your own repositories and accounts.
