What we build
Application Development,
End to End
Transform your ideas digitally from requirement gathering to final project implementation, with our custom application and product development services.
Maintenance, Enhancement & Support
Software evolves after the first release. The Eternal team stands by for application maintenance, enhancement, and support long after your product goes live.
Third-Party Product Customisation
Off-the-shelf and open-source products rarely meet 100% of a client's requirements. Eternal has customised third-party code across AWS-hosted, server-level products and open-source platforms like Magento, closing that gap.
Mobile Application Development
One of the earliest mobile app development agencies, Eternal builds native iOS and Android apps as well as hybrid, cross-platform experiences for utility and enterprise-level use cases.
Our lifecycle
Web Application Development
Life Cycle
Team Eternal always focuses on client success — and success is not overnight. We follow a precise process, project planning, and execution across each stage of the development life cycle.
Stage01
01
Requirement Process
Every engagement opens with project analysis and consultation, hands-on requirement gathering, transparent project budgeting, and formal contract acceptance before a line of code is written.
Stage02
02
Planning Process
We plan resources and project timelines, then translate them into a functional specification document that keeps the whole team — and the client — aligned before development begins.
Stage03
03
Prototyping
User experience design moves into HTML and front-end scaffolding, validated through UI/UX testing — so the look, feel and flow of the application are proven before back-end work starts.
Stage04
04
Development Process
Our engineers build the back-end, source code, database and any third-party integrations, deploy to a staging server, and run unit tests before anything moves further down the pipeline.
Stage05
05
Release & Evolution Process
We manage change requests, deliver the final build to production, train the client's team and hand over documentation, then stay on for ongoing maintenance support.

★★★★★
Large scale MongoDB development delivering multi type content within complex collections with embedded typing and logic and in multiple languages on AWS. Technically complex but delivered faultlessly. Thanks everyone at Eternal, job very well done!
Richard P.Bournemouth, GB
★★★★★
The Eternal team did an excellent job setting up our application. It was a complex scenario with several legacy issues, but they worked swiftly and communication was excellent, all managed through a very helpful online project management system. I will definitely be using them again in the future
David H.Leeds, GB
★★★★★
Great team to work with, they fixed a very difficult problem which 5 other coders could not figure out. They did in an hour. Amazing team, will hire again for future projects.
