    Ukraine - Last active: 07/30/2012 - Tests: 4 - Portfolio: 9

    4+ years xp in development of web-apps, complex sites and services that require scalability and conformation to the most current web standarts. You are welcome to use my strong skills in (D/X)HTML, CSS Layer 1-3, JavaScript/Ajax, XML/JSON, Python, Java EE with modern frameworks and different database engines such as MySQL, PostgreSQL, Oracle for developing featured web-2.0 websites as well as multitier enterprise-level web- applications. In my developing practice I use modern MVC/ORM/Ajax frameworks (such as jQuery, prototype-js, Spring, Struts, JSF, Hibernate, Tiles, etc. - take a look at the rest of my profile for details) in combination with strong OOP, design patterns, unittesting. That's why you'll get the product built using the best programming practices instead of "inventing the wheel". Over the last years I was working in relatively big outsourcing company. So it's usual for me to be envolved in a full development cycle of big web- applications, communicate with customers, have business trips to other countries and participate in remote teams.

    Microsoft Certified | Senior Developer | Team Leader

    Australia - Last active: 6 days ago - Tests: 9 - Portfolio: 3

    Over the last 15 years I have continued to develop my career, skillset, knowledge and experience. The last couple of years, upwork has introduced me to a great number of great people and projects. Two of these projects will be briefly outlined below. The first was designing and implementing a 4 million hits / day infrastructure to handle advertising banners. This client had a business requirement to greatly extend the reach of the live infrastructure. This project was completed in PHP / MySQL and is currently hosted on a cloud platform. This project scales automatically as required to handle any variation in the daily load. The final project was a hospital scheduling task. This client worked for a hospital and had over 30 different scheduling rules for every time-slot. The client used to do this manually and it took hours every week. I came up with a VBA based solution that would automate this task. On completion, the task took about 20 seconds to execute and correctly assigned all time-slots to the correct hospital resources. I would like to continue to be exposed to new and different challenges, that will further develop my skills and career. I also really enjoy making new contacts on the upwork network. I look forward to the many varied opportunities and roles that upwork offers.
