How do agile teams function?

Agile teams are usually cross-functional, composed of developers, designers, and testers. They work in close collaboration and are empowered to make decisions independently. The team is responsible for the entire software development cycle, from gathering requirements to deploying the final product. Agile teams hold regular meetings, often daily, known as stand-ups to discuss their progress and address any roadblocks.

What is custom software development and how can it benefit my business?

Custom software development refers to the process of designing, developing, and deploying software solutions tailored specifically for a business's unique requirements. Unlike off-the-shelf software, custom software is built to align closely with your business goals, operations, and user needs.
Flexibility and Scalability: As your business grows, your custom software can easily be adapted to meet new requirements.
Competitive Advantage: Owning unique software can serve as a significant competitive edge over businesses using generic solutions.
Highly Tailored: Custom software caters specifically to your business needs and is not a one-size-fits-all solution.

How does code review benefit software development?

Code review is an integral part of the software development process. It involves examining the source code for issues related to quality, maintainability, and security. Code reviews provide an additional layer of verification and help in identifying errors or vulnerabilities that automated tools may miss.
