Hire an Android Programmer Team With Four Ages
With Four Ages Android developers’ services, you can choose any of these flexible cooperation models:
Product Development
With this cooperation model, working with an Android app development company means we take full responsibility for the entire process, from initial architecture design to implementation. You can either work with our team of qualified candidates, managed by a certified PM, or oversee the engineering team yourself — it's up to you.
This approach is also a good choice if you don’t have a technical CTO but know what needs to be achieved from a business perspective. In such a situation, we offer fractional CTO services, where a software architect and a UI/UX expert will start working on your project and design the solution from scratch. Afterward, we create a team of experts to handle development and implementation.
Team Extension
This collaboration framework assumes a natural extension of your current IT team. The experts from our side will join your engineers on a remote basis to reinforce the efforts on Android development. If you're looking to hire an Android programmer, this model allows you to seamlessly integrate additional talent into your team.
Team extension is a great choice when you need to find extra resources to accelerate software development, meet deadlines, and reduce time to market. It’s also ideal when you need to add specialized talent to your team for a specific period without an ongoing full-time commitment.
Staff Augmentation
With this cooperation model for Android development, we assemble a team of skilled engineers managed by our certified PM. When selecting developers for your project, we consider their past experiences in the same or adjacent industries. As an Android development company, we ensure each team member brings relevant expertise to deliver high-quality results at a competitive cost.
Once a dedicated team is complete and starts working on Android development, you will receive regular reports on the project's progress and budget. Our PM will provide information about milestones achieved, current spending, and other essential details each week or as agreed.
