    Good afternoon. I conducted a basic assessment of your project, but I lack information to calculate the budget. I have a few questions; we can discuss them via text, but it's better to have a call (if convenient, I will create an audio meeting through Hangouts in Google Meet).
    About me: What sets me apart from competitors?
    I am a programmer, IT solutions architect, with 12 years in IT. I founded the company ingello\systems, previously I was the technical director of the company TAXER. Before that, I was the director of the company Sitio. Prior to that, I was a senior programmer at Igrolan.
    During my career, I have saved startups and companies (not exaggerating) hundreds of thousands of dollars. There are specific examples, see below.
    I am looking for interesting and complex, multi-stage projects, and I also consider equity participation in startups (I have experience). You can trust me with a project of any level, and here is the proof:
    Video about my team:

    Our website:
    https://systems.ingello.com
    Here are some interesting projects I have worked on:
    Garage — for this startup, we saved at least $40,000 (!!!) on the development of mobile and administrative applications.
    https://business.ingello.com/garage
    Taxer — this was a previously funded product that became profitable, used by hundreds of thousands of Ukrainians. I collaborated in the role of Technical Director (CTO).
    https://business.ingello.com/taxer
    And here we, on the contrary, lost several thousand dollars due to an architectural mistake. But then we rehabilitated. This is a very complex project for a TOP-1 Amazon partner, a cool German brand.

    Mobile applications and admin panels for a taxi and delivery service. Here you can see a bit of the working process.

    Among our cases, you can find those that are similar to your project — some infrastructurally, some architecturally, some functionally. Here are a few links.
