Talesh started working with Magento in the confusing early days of Magento Beta. Over the last 10 years he has transitioned into a role of Consulting Magento Architect working with companies to direct (and occasionally rescue) their Magento projects.
All throughout his 20 years working with web application development Talesh has also held a keen interest in the security issues. Given the recent renewed interest in web application security Talesh has started evangelizing defensive development practices and helping teams build defensive Magento sites. Some of that manifests in the security podcast at magedef.com.
