Hiring an internal development developer offers several key advantages. Firstly, it provides greater control over the development process. You can directly manage the developer, set priorities, and make changes as required. This direct interaction can lead to better understanding of your business objectives, resulting in a more tailored product.

Secondly, internal developers are typically more committed to the company’s success. They are part of the organization's culture and understand its goals, which can translate into a higher quality output.

Thirdly, hiring an internal developer can lead to faster communication and problem-solving. Since they are within the organization, issues can be addressed immediately without the need for scheduling meetings or dealing with time zone differences.

Fourthly, internal developers can provide continuity and consistency. They can maintain and upgrade systems over time, ensuring a smooth transition between different stages of development.

Lastly, in the long run, having an internal development developer may be cost-effective. While the initial costs might be high, over time, the costs of training, integrating, and maintaining a developer can be less than outsourcing or frequently changing contractors.

In conclusion, hiring an internal developer can offer control, commitment, efficient communication, continuity, and potentially lower costs.
