<p><span style="background-color:rgb(255,255,255);color:rgb(68,68,68);">We have specified a set of proven and flexible technologies that allow us to create functional apps of any complexity from scratch. And that is how we do our thing.</span></p>

Our process is simple, reliable, and available to customers. We provide access to all the necessary project tools and constantly communicate with each other. A Scrum-based workflow allows us to cooperate efficiently, even with time-zone differences between our team and clients.

We are transparent, and so is our process

<h2>Overview</h2><p><span style="background-color:transparent;color:#000000;">The founders of </span><a target="_blank" rel="noopener noreferrer" href="https://shootq.com/"><span style="background-color:transparent;color:#1155cc;"><u>ShootQ</u></span></a><span style="background-color:transparent;color:#000000;"> set a goal to meet the needs of photographers and develop their own web product that would offer broader and more relevant functionality than most standard CRM systems. The app was designed to solve real-world problems, allowing you to track customers, schedule photo sessions, track tasks, advertise studio services, and create email marketing templates.</span></p>

We found Gearheart through Upwork. We started small with them, and after seeing the quality of their work and project management skills, we expanded our engagement over time. I had two development teams at one point of equal size working on the project. I ended up firing the other development team and doubling Gearheart’s workload after I saw what they were capable of.

Let’s build your first app together

<h2>PURPOSE AND NEED</h2><p>The <a href="https://shootq.com/">ShootQ</a> photography management software had been on the market for ten years, and even though it operated well, the technology and the design were out of date. That’s why the owners have decided to develop the second generation of the application relevant to present-day business tasks.</p><p>When the <a href="https://gearheart.io/team/">Gearheart team</a> received a request to upgrade the application, the design and the back end were already under implementation. Our major task was to develop the front end, including the application’s interface, but, over time, we took over the entire project.</p>

<p>Initially, we received a completed back end and design of the project and took charge of the front end. Gradually, we moved on to the back-end frontier, where our target was to take an innovative approach and apply modern design.</p><p>Nine people in total were involved in the project, developing the entire set of functions to release the app as quickly as possible. At first, three developers from the ShootQ team were responsible for the back end, while Gearheart, represented by five full-stack experts and an analytic, worked on the front end. Over time, we started to manage the whole project.</p><p>After the app’s release, all ShootQ users were moved from the outdated version of the app to a new one, which offers many useful features, which we explain in more detail below.</p>

9 people in total were involved in the project, developing the entire set of functions to release the app as quickly as possible. 

So we started with  the team

We made a product, with a great number of features

<h2>TECHNOLOGY</h2><p>The ShootQ app was originally developed on Angular 2 with the back end based on Django. Eventually, we updated it to a new version of Angular 7. In addition to the Angular framework, we also used the <a href="https://github.com/ngrx">NGRX</a> extension.</p><p>Gearheart is one of the first companies to ever use Angular 2 for web product design. Two years earlier, when Angular 2 was under development, we used it to rewrite a <a href="https://gearheart.io/projects/timer/">Timer</a>. By the time Angular 2 was officially released, the above-mentioned project had already been in production. Thus, we could prove our experience at Angular 2 when we received an order from the ShootQ founders.</p><p>Main technology points to consider:</p><ul><li>The data of the CRM for photographers is kept at PostgreSQL, while the code is stored at <a href="https://bitbucket.org/">Bitbucket</a>.</li><li>Bitbucket Pipelines are used to run tests, measure the code coverage level, and update the test server.</li><li>The application server is hosted at <a href="https://aws.amazon.com/">AWS</a> and run by Docker Swarm.</li></ul>

Their project management is their most valuable asset. This is one of the biggest reasons we’ve stayed loyal to Gearheart, and why we consider them to be such an integral part of our process now.

<h2>RESULTS</h2><p>Following the release of the updated version of ShootQ, the Gearheart team continued to work on product updates and improvements until the end of 2019.</p><p>Based on the data from <a href="https://www.featuredcustomers.com/vendor/shootq">Featured Customers</a>, <a href="https://shootq.com/">ShootQ</a> is popular among web users. ShootQ client testimonials have a total content usefulness score of 4.7/5 given by 1040 users. Many popular photographers like Mike Larson, Sara France, Lukas &amp; Suzy Vandyke, and others prefer ShootQ to manage their daily tasks.</p>

I've managed even to implement repetition with ;.
