FAQ
Will I get the source code?
Sure. I deliver the source code and instructions to deploy the API as well as all commands needed to deploy the database structure.
I am not sure how large is my project. Which package should I choose?
You can ask me before you pay so I can review the specifications and your goals and let you know what option suits best. In case you have already chosen a plan incorrectly, I will cancel your order and will let you know what plan to choose (larger or smaller).
What does determine if a project is large or small?
It can depend on many factors: the number of entities (tables), the number of fields on each entity, how many relationships are between entities are, rules, etc. Since there is no way to configure the gig prices to this kind of detail, it is better to contact me first.
What about communication?
I can write in English or Spanish, but comments and code will be delivered in English. Once the project is started you will get regular updates as long as it is completed and maybe some questions to clarify some queries I could find during the development process.
