Given the complex nature of your project, verifying and comparing an already developed mobile app, desktop application, as well as other parts such as Firebase, Api Dev, HQ user management and Landing, I believe I am the best fit for the job. With 7 years of extensive experience in software development and specialization in web and mobile apps for Android and iOS using languages like PHP, Laravel, CodeIgniter, Python, JavaScript, WordPress etc., I have gained a deep understanding of app architecture, coding standards and debugging techniques.
In addition to my development skills, I have a strong background in database management including Firebase and SQL which will be crucial for evaluating their work. My previous projects involved continuous integration/continuous deployment (CI/CD), requirement analysis, designing architectural plans, thorough testing- all processes that I can utilize while thoroughly examining the company's claims about significant hours spent on tasks.
My passion lies in creating robust and efficient software solutions empowering me to deliver beyond client expectations. Henceforth I assure you is complete transparency throughout this process. With detailed analysis reports backed by solid proofs, I will give you an unbiased decision about whether the hours billed are justified or not. My rate is $100 but given the magnitude of your project I am open to earning your trust on a long term basis by providing valuable insights over monetary gains.
