Scope

What we do

Custom software development means designing and building software from scratch for a company's specific processes. ORELSIS develops scalable enterprise software with C++, Go, Python and JavaScript, along with cloud, AI and machine learning technologies. We manage the full lifecycle, from analysis to go-live and maintenance.

What we deliver
  1. 01Requirements analysis and scope document
  2. 02Software architecture and technical design
  3. 03User interface and experience design
  4. 04Tested, documented source code
  5. 05Integration with existing systems
  6. 06Go-live and user training
Process

Four steps, measurable progress

  1. 01

    Discovery

    We clarify the scope by analysing your business processes, users and technical constraints.

  2. 02

    Design

    We design the architecture, data model and interfaces, and gather early feedback with a prototype.

  3. 03

    Development

    We build in short iterations and share working software with you at the end of each one.

  4. 04

    Go-live

    We complete testing, deploy the software and train your teams, then move into maintenance.

FAQ

Frequently asked questions

We mainly use C++, Go, Python and JavaScript. Cloud infrastructure, AI and machine learning are also part of our solutions. We choose technologies based on project requirements.

Source code ownership and licence terms are clearly defined in the contract. We agree on the options with you at the start of the project.

If your processes are standard, an off-the-shelf product is usually faster and more economical. For unique processes that give you a competitive edge, custom software is a better fit. We often recommend a hybrid approach that combines OREL products with custom development.
