I have worked with Alex over 1.5 years with my company site and intranet systems. At first I needed only someone to finish a 2-3 week project, but this has led to a long term partnership. Alex has been easy to communicate and he has kept the deadlines. I would definitely recommend to use his services and will work with him in the future myself.

Rocklab was able to take a very weak existing code base and rewrite it in a way that was sustainable. We also executed strict user experience requirements that is very unique to traditional design. The Rocklab team continually came through under deadline time and time again.

We have been using RockLab for a few years without an issue. They helped us in a project and provided us with the best service. We had a great experience with them. RockLab helped us revamp our website Teabloom.com, both functionally as well as visually. Their team is very responsive and very knowledgeable on all aspects of web development as well as web design. We highly recommend them for any Magento related project.

Visit Profile

Please introduce your company and give a brief about your role within the company?

RockLab is founded by two IT experts(I and my friend Alex Kryvtsun) who have been working in the IT outsourcing industry for around seven years. Although our team is young, each developer in our company has many years of experience. While working with multiple clients and dozens of projects, we have learned a lot about customer's needs, expectations, and challenges. We believe that our customer's success is our success.

What was the idea behind starting this organization?

My friend and I were working in outsourcing companies for five years. It was an excellent experience, but we always dream about founding our company to provide the best service to clients. And with the same thought, we founded our company three years ago. Now we are actively growing and expanding.

What is your company's business model–in house team or third party vendors/ outsourcing?

In our company, we have two independent departments - PHP and Python The PHP team specializes in Magento, in particular: - Magento backend / frontend - Bugfix - MultiStore - Marketplaces - Multi Vendors - Creation of individual modules. Python team develops complex web apps in: - Django & Flask - React & Redux - Сreate a custom CRM systems - Schedulers - Dashboards

How is your business model beneficial from a value addition perspective to the clients compared to other companies' models?

We are into outsourcing business. We regularly take projects and have high-level developers and reasonable prices.

What industries do you generally cater to? Are your customers repetitive?

We cater to an extensive list of industries. There are some examples: Healthcare, Law, eCommerce, Fashion, and Tourism

Mention the objectives or the parameters critical in determining the time frame of developing a web app.

I think minimal time-frame for a production-ready but straightforward app is one month, but usually, we spend about 2-3 months on small projects, about six months on mid-size apps and 6-18 months on big projects.

How much effort in terms of time goes into developing the front end and back end of a web app?

We are full-stack developers so experienced in both front-end and back-end. The time frame depends on the amount of work.

What are the key parameters to be considered before selecting the right platform for a web application?

We are experts in Python, PHP, and Magento, so the platform depends on the client's needs. We usually develop web apps and sites to React, Django, and Laravel and eCommerce solutions in Magento.

Which platform and technologies do you prefer to use in the development of your web apps?

- Magento: We create eCommerce or marketplace site from scratch, migrating from 1 to 2 version, develop custom extensions, edit existing modules/grids/pages, integrate payment/shipment methods, install security patches - Laravel/CodeIgniter: Create SPA from scratch with Vue or React, create any web site from a blog to the vast web app - Python/Django: Create sophisticated web applications from scratch using React, Redux, Apollo

Which Content Management System do you prefer to use (Wordpress, Joomla, Drupal, etc.)?

For the last eight years, we've worked with a different type of CMS (Magento/Joomla/WP) and frameworks (Laravel/Zend/CodeIgniter). And now we can work on any CMS or framework where use MVC pattern.

Do you provide website maintenance services?

Yes, we do. After finishing active dev process, we always care about our projects.

What are the key factors that you consider before deciding the cost of a web application?

The main key factor is - detail specification. When we have a functional specification and mockups, we can bifurcate the project into small components and evaluate each one. And after that, we have the correct cost.

What kind of payment structure do you follow to bill your clients? Is it Pay per Feature, Fixed Cost, Pay per Milestone (could be in phases, months, versions, etc.)

We prefer hourly rates and billing by weeks.

Do you take in projects which meet your essential budget requirement? If yes, what is the minimum requirement? If no, on what minimum budget you have worked for?

The minimal budget requirement is $1000 for new clients.

What is the price range (min and max) of the projects that you catered to in 2018?

The price range of the projects we catered in 2018 was from $5000 to $50,000.
