Our Expertise

How we helped clients grow their businesses

From an MVP to a successful e-learning platform

Defined Learning contacted us to develop the MVP version of the Defined Careers app in Ruby on Rails. The whole code-base was built from scratch which later was integrated with Defined other existing systems. Our UX/UI team was also responsible for the designs later.View project

faq
  1. Outdated manual processes: If manual processes are slowing down your organization, custom software can modernize and streamline them.
  2. Integration challenges: If current systems can't effectively communicate or share data, custom software can be developed to integrate them.
  3. Unique business requirements: If your organization has specific needs that can't be met by existing software, custom software can be designed to meet those needs.
  4. Scalability limitations: If your organization is expanding and existing systems can't keep up, custom software can be designed to grow with your business.
  5. Security risks: If sensitive data is being handled, custom software can be developed with stronger security measures to protect that data.
  6. Competitive advantage: Custom software development company can give your organization a unique advantage by providing a customized solution that meets your specific needs.
Different custom software development firms have varying pricing models, often charging by the hour for software development services. However, cost depends on project complexity and other factors. It's important to clearly communicate project requirements and goals before asking for cost estimates, but remember that a lower price may not always result in a better solution, especially in the software development process.

As a software development firm, we can deliver our services in two different ways:

  1. Dedicated team: a method in software development services where a company is contracted to deliver a specific, well-defined product or set of products within a specified timeframe and budget. The focus is on providing the project goals, rather than ongoing support or maintenance.
  2. Staff augmentation: in software development, works by adding external software developers to a company's existing in-house development team. The external developers are integrated into the team and work alongside the in-house developers to complete the software project.

Selleo advocates following the rules and principles of Agile and Lean software development methodologies as the best approach to managing projects. We use Scrum as a lightweight agile process framework to manage our software development as it ensures an appropriate level of communication and collaboration with the client people. We perceive it to be a critical success factor in the execution of outsourced projects. The methodology many times proved to greatly help to integrate all the team members involved in the case of both independent and augmented development teams.

Scrum business processes
The cost of custom software development services can vary significantly depending on several factors. Firstly, the complexity of the software plays a crucial role in determining the cost. More complex software with advanced features and functionality will generally be more expensive to develop. Secondly, the size and experience of the development team can impact the cost. Hiring a large team or a highly skilled team of developers may result in higher costs.

Our custom software development process involves several key stages:

Requirements analysis: We engage in conversations with you to precisely understand your needs and business goals.
Designing: We create a software design and prototype that takes into account your requirements.
Programming: Our team of programmers begins the process of software development.
Testing: We thoroughly test the software to ensure it functions correctly and meets all requirements.
Deployment and support: We assist in the software deployment process and provide technical support after deployment.
