    I am an experienced software developer specialising in trading robots. I develop bots for MT4 and MT5. On top of that, I can develop bots for other platforms that don't use MetaTrader or need integration with APIs. I have years of experience on this. During development, this is what I do. - Develop an Expert advisor for semi or fully automated trading. - Back test and forward test the strategy and optimise it for better performance. - Add a User Interface to help you have total control of your EA. - Advise on what works best for the Expert Advisor. - If needed I can help set up a VPS to get your EA running 24/7. I also have tertiary level Mathematical and Statistical skills with good communication as well. Therefore, you are in good hands. Welcome.

    Hi My name is Kamran. I am an Expert web developer with many years of experience in the industry! I worked almost exclusively with some of the biggest companies and have been adding more skills to my arsenal over the past couple of years as well. The idea is to move to newer technologies, but I don't think I will be abandoning WP projects entirely, not for a while. My main strengths are: ✅ - Clean coding ✅ - 100% WordPress coding standard compliant, and I can adapt to any standards used by your development team ✅ - High availability - usually respond within 5 to 10 minutes to any queries during CST work hours ✅ - Fast and top quality work == Some background of my previous job experience == I worked for a Fortune 500 automotive company in a reporting and analysis position, and also building and maintaining a website in the company's intranet using Perl and MySQL. After that I was in charge of supporting a website built with Java and the Spring framework, using both MySQL and Oracle databases, for customers worldwide. I also worked at the tech support helpdesk for that same company for over a year, troubleshooting Linux servers and workstations, networking and other data related issues. I was also in charge of administering KBOX ticketing system for over a year, from content management to database administration, to scripting solutions for its customers. I also have knowledge in scripting using different technologies, such as VBScript, Javascript, Linux shell scripting, Perl, and some Powershell, as well as VBA for Excel and HTAs. I was regularly troubleshooting C and Java programs for bugs and/or enhancements as well. After that, I moved to a company named Softtek as a Software Engineer. I was part of a team that develops WordPress plugins and themes for an American multinational conglomerate corporation. The last position I held was for yet another company as a Linux intermediate administrator, where I was in charge of managing users with Centrify and I also installed Cacti to monitor some of the company's servers running CentOS. Currently, I'm a full time freelancer developing WordPress plugins and themes. I also do core PHP, Laravel, VueJS, and some React/React Native work. If you are interested in working please let me know and it will a pleasure to see how our company can over-deliver for you!
