Product development phases

  1. Brief
    Short description of the product covering the major features and the use cases. In most cases, it is done in-house, however, we can create it for you.
  2. Specification
    Detailed review of the product which covers all the possible features and use cases as well as technical requirements. Designers and developers use this document to estimate costs for their work. Create your own spec or request us to develop it for you.
  3. Design
    We do not create designs. Clients typically approach us when they already have layouts, or they are in the process of creating them.
    However, we can recommend trustworthy studios or freelancers we have worked with.
  4. Development
    This is our specialization. We code websites and mobile apps. Please check out the stack of technologies we use. To get a quote on your product, send us your specification or design layouts.
  5. Support
    We do support most of the projects we have coded. Our clients tend to like continuing working with us. In some cases, we can start supporting projects we did not originally code. Show us your product, and we can discuss it.

    • Meduza

      "If not for these fellas, Meduza would not have been launched. I mean it would not have been launched within such a crazy timing. They found the right team, launched the website, publication system and two apps for less than three months. And they did it amazingly well. They are not cheap but worth it. These guys were a great help and found us a dream team".

      • V–A–C

        The guys pulled off the task of making a site with an incredibly intricate structure and lots of complex visual solutions. I would particularly like to note that the guys have no "impossible": they searched for solutions to every challenging task. Thank you so much for your patience, for the easy communication, and for all the alterations we came up with in the process.

        • Catery

          "A big part of our business is handled offline — dozens of business processes, integrations w/ our caterers, w/ our accounting dep. P&K got to the bottom of every little detail. They even participated in conf. calls with our legal team and consultants. Expensive? — Yes. Worth it? — Hell yeah!"

            "We have been looking for a reliable contractor for a long time. We found P&K agency and this is the only company we want to work with onwards. The agency which listens to you, talks to you in terms you are capable to understand and deliver the best results is truly unique. We have never worked with the developers who can do all this".
