    Sergii Ievliukhin

    Java Technical Lead

    Ukraine - Tests: 1

    I have 10+ years experience in IT as a Java Web Developer. Huge experience in a Single Page Applications with a lot of media resources including video, svg, audio, etc. Experienced in development of SAAS applications. I’ve been coaching Java/Javascript. It means I have advanced knowledge of both: Front-End (HTML, CSS, Javascript) and Back-End (J2EE, etc) Outstanding experience in cross browser/platform Front-End allows me to build complex component-driven UI based on MVC and Action Listener patterns. Experienced with GWT, JQuery, Sencha, AngularJS, Atmosphere, pure Javascript, SockJS, Stomp.js, etc I reckon that the magic doesn’t exist so I know how works almost every popular framework/technology under the hood. I know how to organize Security over Stateless REST/Web services and how to eliminate vulnerabilities: SQL injection, XSS, Clickjacking, etc. Have a strong knowledge of one of the most popular framework for Java - Spring (security, data, mvc, aop, etc..). I know what are bottlenecks, so I can develop fast horizontally scaled server side applications. Have an understanding which storage type should be applied in a concrete situation: either NoSQL with optimistic transactions or SQL with ACID transactions or even with distributed transactions. All my customers were/are from the U.S. and there haven’t been any problems in communications. I’ve already been to the USA that's why business trips shouldn't be a problem, JIC. My work is my hobby, but my hobby isn’t the only work.
