About QBurst, with offices in Fairfax (Virginia, USA), Sheffield (England, UK) and Trivandrum (Kerala, India), is a software services company that provides services in web 2.0 and mobile application development. Having developed enterprise-grade products for several successful startups and medium-sized enterprises, QBurst has earned the reputation of being a high-tech cost-effective service provider. QBurst's delivery cycle is much faster compared to large consulting companies, and as a QBurst client you get personalized attention. We have much more in-depth knowledge of web 2.0 and mobile technologies compared to most of the large consulting houses.

Mission "To be a world leader in developing custom web and mobile applications for startups, small and medium enterprises".

History QBurst was started in India in 2004 by three software professionals. They had a wide-range of development and consulting experience before starting QBurst. The initial clients of QBurst were startups having small budgets but with big dreams. QBurst helped them quickly develop robust, fast, scalable and highly-available applications within their tight budgets. The apps were developed in small and short iterations following the principles of agile development. This enabled these startups to reach their target audience early, engage users, get continuous feedback and then make quick changes to their applications to meet real end-user needs. These companies were able to quickly change course according to market conditions. QBurst started growing steadily when some of these startups (like freepatentsonline.com) became immensely successful. In 2008, QBurst started its US and UK subsidiaries, QBurst USA, Inc and QBurst UK. QBurst currently employs 140 professionals that include developers, graphic designers, QA, business analysts, architects, XHTML/CSS specialists and so on. QBurst is providing the same agile-style methodologies to established companies like Plusnet, a broadband services provider in UK and a wholly owned British Telecom subsidiary, to enhance their legacy applications.

Project Management We typically use a hosted instance of Trac or Redmine for project management. Customers are also given access to the project tracking software. Trac and Redmine have integrated version control (Subversion), wiki, task and milestone management, document management and bug tracking facilities. In addition, we have integrated build tools like Cruise Control. Our clients can get all project related documentation and reports in one central place accessible from anywhere. The application under development is hosted from day 1. This allows the client to get deeply involved in the development process and provide early feedback.

Quality QBurst's goal is to deliver quality products to our customers, which means products that meet all the functional as well as non-functional requirements such as speed, scalability, reliability, availability and maintainability. We rely on agile processes to achieve our goals. We understand that requirements evolve and change during the project life cycle and definitely during the product lifetime. These changes may be driven by new technologies, which change user expectations. Changes become necessary when your organization grows where you could go from a shared hosting to a dedicated server to maybe a load balanced server cluster (if your application becomes very popular). There is no such thing as future-proofed software. Source code must undergo continuous enhancements and refactoring. This is where agile methodologies play an important role in. By creating automated unit and functional tests, developers get the confidence to continuously refactor and improve. Changes to source code that break the application are caught by running automated tests. A project is split into multiple time-boxed iterations. Depending on the nature of the project, each iteration would typically last 2 to 6 weeks and would implement a set of use cases and feature sets. Customer interaction is crucial for the success of iterative projects.

Featured Projects

QBurst has successfully built and deployed close to one hundred web applications using different MVC web app frameworks like Symfony, CakePHP, Django, Zend, Struts, Spring, Ruby on Rails, and .NET. We have extensively used one or more JavaScript and AJAX toolkits like ExtJS, Scriptaculous, Prototype, Dojo, JQuery, YUI and MooTools to bring richness and responsiveness to the UI. Most of these webapps are powered by MySQL database, but on some specific developments we have used databases like SQL Server, Oracle and PostgreSQL. We have also used non-relational databases like Google’s BigTable for one of our app engine projects and Lucene in a few others where there is a lot of unstructured and text data. These webapps are hosted in a variety of environments - shared, dedicated, virtual dedicated and of late mostly up there in the cloud (Amazon EC2, Flexiscale and Google). Mentioned below are some of our interesting projects:

Featured Projects

Full-text Search Engine and Document Delivery System This site delivers 10 million+ pageviews a month and has an Alexa worldwide rank of 1600. Our customer who owns this site started operations in 2004 and is now #1 in their space. The website primarily serves documents. The website primarily serves more than 50 million documents stored in MySQL database. Read-only replicas of this database allows distribution of load between multiple servers. The site has a powerful full-text search feature built on top of the open-source Lucene search engine. Lucene's indexer, indexes the documents in the database and stores them in multiple index shards. Each shard or fragment is of a manageable size. Searches are parallelized and handled by around 10 search servers with each server handling a portion of the index. The results are merged, ranked and served by the web servers. System architecture is akin to and inspired by Google. The site is also search-engine friendly with all 50 million documents in the site being spidered and indexed by Google. The data assets are monetized through Google AdSense and a document delivery system for paying customers. The site also offers features like saved searches, search-term alerts and portfolios. The site was developed using PHP, Symfony, Java, iBatis, Lucene and MySQL. Load balancing and high-availability was achieved by having a system with multiple web and search servers, and having read-only replicas of the MySQL database.

Re-engineering Business Support Systems for a Residential ADSL Provider This project was done for a major broadband provider in UK having more than 200,000 customers. Their entire system was built in-house 10 years ago and evolved over the years. The system could no longer adapt easily to accommodate new requirements. As a result, launching new products and reacting to competition and market conditions became a slow process. Even small changes became too time consuming to implement given the level of testing involved. QBurst provided resources to work with the customer's development team to undertake a major re-engineering effort. The team decided to go for API-driven subsystems. Subsystems would communicate with each other through APIs. Legacy subsystems were wrapped under APIs to effect a smooth transition. A new MVC framework was created so that development is streamlined. Permissions were managed within the framework so that developers don't have to worry about that. Technologies used include PHP 5, custom MVC and ORM frameworks, JQuery and MySQL.

Testing Services for the #1 Widget Platform Company This customer based in Virginia has the most widely used widget platform in the Internet in terms of the number of widgets served. Their platform allows widget developers to create, distribute, share, track and monetize Internet widgets. Widgets can be built using Flash, images or HTML/JavaScript. The platform allows the widget developer to deploy their widgets into a number of popular social networking sites (FaceBook, MySpace, Hi5) and widget galleries like iGoogle. The number of permutations that needed testing is very high given that the customer needs cross-browser compatibility too. QBurst was engaged to do QA for the widget platform. Given the fast paced environment, releases were made frequently and at least once in 2 weeks. This made testing a challenge since there isn't much time to manually test every combination. So QBurst has started working toward automation of tests. We have finished automating all the smoke tests, so we can quickly catch any major problems. We have now started automating the entire set of regression test cases. Once that is complete, regression can be done in a matter of hours instead of days. This will give developers faster feedback and will further shorten the development cycle. Most of the test cases were automated using the Selenium framework. However, Selenium cannot automate Flash application testing and this is a problem that we are now trying to solve.

Personnel, Equipment and Vendor Management Systems for a Big Construction Company This customer is a $350 million construction company having thousands of employees and a large number of contractors. Headquartered in Dublin, CA, they specialize in heavy, highway and civil engineering construction. They needed a system to keep track of hourly rates, worker skill level and training, accidents, disability and insurance information, work and worker locations and equipment usage and rentals. QBurst developed the system using Spring, Hibernate, Oracle database and Dojo for automating the personnel-management related requirements. The key feature of this system is that there is only one page. The different sections of that page are updated through AJAX calls. This makes it very usable since all the information about an employee or contractor is accessible from the same page, thereby improving the efficiency of supervisors. This system also interfaces with the other enterprise systems like Dispatch, Accounting and Payroll.
