vTiger CRM ERP Expert

Greece - Tests: 1

I am an Internet Technologies and Software engineer, specializing in Vtiger CRM / ERP planning, development and implementation. My 8 years experience in Internet Technologies and 5 years focusing on vtiger allows me to implement any vtiger customization. I have implemented various integration projects of vtiger with 3rd party applications using WebServices, such as Joomla, Jomres, Wordpress, Virtuemart, OsCommerce and more. The strong background on business process re-engineering and business process integration allows me to easily understand the business needs on their CRM / ERP application to ensure the customization success. In the past 5 years i have worked with various companies in different industries around the world to help the design and the implementation of their CRM / ERP systems. Integrating their individual business processes to the vtiger platfrom, i have developed many modules for vtiger in order to "digitilize" companies specific processes and workflows to Vtiger platform. My philosophy for CRM / ERP systems is summarized in the following principle: "You cannot manage something that is not measurable". Towards this principle i assist my clients develop a system where they can track down all the information flow produced by their business processes and also the tools to streamline them, providing all the necessary information (BI) to the right department / user. I enjoy helping companies create their own tailor-made software that reflects their real needs, allowing the business to effectively utilize their resources and automate trivial processes thus saving time and money, that they can invest in growth (that is after all what software can provide time / money).

Slava Hatnuke Agency Contractor

Senior Web Developer (Node.js, AngularJS, MongoDB)

Ukraine - Tests: 3 - Portfolio: 2

10 years experience in web, architecture and development. Key technologies: JS, Node.js, AngularJS.., Twilio API, MongoDB, MySQL, Oracle, Docker/Vagrant, Automated Testing/BDD, Object Oriented Design: SOLID, GRASP... Just use modern technologies and approaches to solve issues. Respect trust, honesty, simplicity, organised process and flexibility in decision making! That is our way! Each project should use best practices to be successful. There are some of them: - agile methodologies (planning, backlog, retrospective ...) - object oriented programming - architecture based on the patterns - automated testing (functional and unit) - continuous integration - code review and cross review - safe refactoring of existing solutions - scalable solutions.. Actually I care about fun and quality in web development. Our company love working on projects which indeed need for users and make people little bit happy. We want to be clear and use agile practices to make development processes more transparent. We implement project step by step with best practices and grow functionality and keep quality. Have you seen the fish lived without water? Similarly project can’t live without suitable infrastructure like management, architecture, coding culture, automated testing, team building, responsibility, respect….. These things are water in the ocean of development, I am just one of them who care about this.
