    Work on a wide variety of Java EE applications in an efficient group with minimal meetings and overhead. It&quot;s 100% remote, work from home, and you can work any hours you choose. You need to be available at least about 30 hours/week. This position is open for US Based candidates only.Our group handles moving applications from one tech stack to another. For instance, moving an app from MySQL/Tomcat/RedHat/JDK6 to SQLServer/WebLogic/Windows/JDK7. Specifically, you&quot;ll be addressing bugs in either code or scripts that arise due to an upgrade of the JDK. These could be brought about the by Java issues alone or the new JDK&quot;s interaction with a different OS or app server. We also create new build processes for the different tech stacks. Often the issues we deal with are very difficult to solve and are not a simple matter of searching for a fix online. They require years of experience in Java, enterprise applications, and build systems.In addition to fixing issues, we are tasked with fully documenting the tech stack migration process and producing a repeatable process, which means committing changes to a source code repository, documenting changes, and generating EC2 images of the servers.As the issues we deal with are challenging and difficult to predict, effective communication (in English) is essential.Experience in at least some of the following is required: WebLogic, WebSphere, Tomcat, JBoss, JSP, Java SOAP, Maven, Ant, Eclipse IDE, SVN, Microsoft SQL Server, Oracle, or Sybase. Basic Linux proficiency is required (setting environment variables, navigating directories, installing software, SCP, archiving files, elementary BASH scripting). Advanced knowledge of Java is a must.

    We have a web application which we lost the original development resource. The site is written is asp.net vb speaking to a SQL 2000 database. The site must be able to speak with the major browser available today. The original phase of the project is about 20% completed, I estimate about 8-12 weeks of 20-30 hrs per week to complete the phase. The project is currently slated for 4 phases and potentially moreOriginally, a great deal of the application was written in T-sql instead of utilizing stored procedures, this will create a requirement for some redesign, although certainly required to provide the necessary infrastructure for future development. The application is geared for users of fire alarm detection panels and the signals which they generate. The application will be geared to support multiple languages (this phase only English), by the proper localization being built in the early stages.The selected developer will be interfacing with our full time in house staff. Phase 1 will consist of corrections to the already written portions, proper localization, conversion to stored procedures, more robust graphics experience, and completion of base design.

    I just redesigned my website page; Test1_CustomerQuestions.aspx. It can&quot;t be published until its CS page is also updated. Currently, the information collected on this page and the previous page; test_contact_info.aspx, is added together and passed through to the last page and then submitted to me as an email. The previous page is also submitted first as a separate email. I don&quot;t want this to change. Please contact Hershel Rich at 303 514-3003 for questions and to confirm your charge and completion time. We can also discuss other corrections.

    Hello I have a custom built software that deals with one of my customers classes they hold, it is a diary and links to SAGE ACT, which is a customer contact management software that you may be familiar with. I am unable to get hold of the original designer and I have a report that is not working on the customer built software which I need somebody to either look at and correct or create a new report that pulls the correct information and I need it done quickly. Reading your page I would like to know if this is something that you can do, I am aware that you will have to look at all both the databases before you can fully confirm but if you contact me on pm@1office.co.uk I would be happy to discuss further. I can give you access to the database and they back where all data is stored so you can look and see if you can do this project.
