With over 15 years experience developing quality software across a number of industries I ensure my code is well tested, performs efficiently and that all web content conforms to accessibility requirements. I plan the full development lifecycle carefully and with each and every application I deliver, I ensure the code is written to the highest standards while adhering to the SOLID principles every step of the way. Security is a prime concern in this day and age and with all web applications I deliver to the customer, I always ensure the proper authentication and authorization implementations are in place and that a proper health check is done to examine the applications security and performance. I can deliver web applications, API's, web pages, web applications and even Progressive Web Applications which will work offline as well as online.
