Celadon Executive Interview

Most of the clients we had were repetitive, and our goal is always to keep it up.
Scope of work depends on the application platform of choice, the complexity of functionality, expected load, third-party licenses usage policy, and many other factors.
Iâd say the first step in app development would be to understand the critical functionality of the application and then develop the first application version in correspondence with these features - a so-called MVP. According to our experience, an MVP requires approximately 2-4 months.
We offer free project estimation and a preliminary consultation to help the client get realistic expectations on this point.
If one should choose only a single platform, the choice depends on the targeted audience and project goals.
Since at Celadon we focus on React Native technology, we often build native mobile apps for both platforms at the same time with minimal losses in cost comparing to a single platform.
The key factors are app complicity, number of platforms, scalability and the number of integrations with other software and services.
Another big deal is to build a system that is easy to maintain and expand in the future. Itâs often much more cost-efficient to put some extra effort in code documentation and flexible architecture at the beginning of the project to benefit in the long run.
We tried different billing structures before, and I can say that no one benefited from Fixed Cost.
Instead, we follow the Time and Materials collaboration model. We believe itâs the best solution for the agile development process in terms of transparency and flexibility.
It means that after we estimate the approximate cost and start the project development, we bill based on the effort in hours. The fee is calculated by hours spent by every specialist on every task â we usually charge every two weeks, at the end of each sprint. With every bill, we also provide a detailed report and the results of the work.
We plan the work scope and always aim to fit the estimated budget, but at the same time, weâre flexible to any changes or suggestion from the client.
In this way, the control over the budget entirely remains in the hands of a client, and we keep focused on the work and providing the expected results.
If we talk about mobile application MVP development, I think the minimum budget was $9000 so far.

Celadon are very professional and managed the project very effectively!
Review Summary
looking for a way to shorten ordering time as much as possible.
Celadon designed and developed a mobile app which is based on iOS and Android. It covers 3 major scenarios: in-venue order, preorder and delivery. The system is also fully integrated with the POS to get the order receipt confirmation, fetch and keep synchronized menu data to optimize the management effort.
Celadon got much freedom not only in technological decisions but also in the overall
project approach and management. The very exciting part was the recommendation system
that helped to improve ordering speed and upsell.

Review Summary
What is it about the company that you appreciate the most?
They stuck with the agile methodology and had sprint planning every two weeks. We could see the visibility of their work. They locked down the scope but were willing to accept requirement changes. Communication was really easy, and their speed was average. The user experience was good.
What was it about the company that you didn't like which they should do better?
They could be faster at developing, but we were satisfied with their work in the end. The quality was really good. Sometimes the quality is more important than the speed.

Excellent team and work!

Review Summary
Generally,
1. They are honest
2. They are quite scientific in their approach. Beyond programming, they are Software Engineers in the full sense of it. They put a lot of thought into the user experience, system security, stability and bring it down to simple programmable tasks.
3. Their project management is great, communication is perfect, and they are sincere.
4. We have started a second project with them, a web application.
5. We overshot the budget by about 20%, which is within tolerance for us in the circumstance,considering we created something that never existed from ground up in 5 weeks.
What is it about the company that you appreciate the most?
They are competent, swift and with excellent communication skills. Plus the price is great. But most of all we are at peace, knowing they are the team of staff we "Have" some miles away. They demonstrated an emotional connection to the project and put all their thoughts and abilities into it.
What was it about the company that you didn't like which they should do better?
Nothing I can think of right now.

Committed, Flexible and Success-oriented
