Every month, we are needing to create about 50 accounts to order specific products from Amazon. We are looking for an automated way, where it will save us time, letting robots do the jobs for us. We have searched for solutions online, there are 2 ways to achieve it, through Amazon API or through Macro. If you have experience on Amazon and automated solution, feel free to contact me, I am interested in listening to your proposal and what you can develop for us.

The App (C++ / Qt or whatever you prefer) needs to convert Simulationresults from Simufact (*.csv) to the Moldflow-Format(*.xml). Simufact is for simulating forging-processes. There are several TimeSteps. We are just interested in the first and the last step. The Grid for the MoldFlow Resultfile (*.xml) must be taken from the Abqus Input File. It ihas a different Grid – so the simufact-grid must be mapped to the Abaqus-Grid (so we use the abaqus-coordinates in the CSV-File. It must be possible to define a Shift and Rotationmatrix (1. shift – x,y,z Value / 2. rotation 3x3 Rotationmatrix). Both Transformations are configured in an config-textfile. No Userinterface!

This posting is for a software engineer with strong Java experience. The candidate should have strong knowledge of the following technologies and concepts: - Linux - Java - Java program profiling, performance evaluation, memory usage, etc. - MySQL - BoneCP connecting with MySQL DB. - Netty(.io) using TLS server side. Optional but useful skills: - OpenSSL - BIO support for client side communications. - Embedded networking concepts. - C/C++ The primary goals of this project are: - Find and correct a serious bug in the existing socket server (Java) which causes the server to stop processing new connections. I assume there is a resource leak, out of pool connections, or some other system level design error. - Suggest and possibly implement performance improvements in the existing socket server. (We have some ideas). - Improve scalability of the existing socket server. - Create a lasting relationship for maintaining the socket server. Additional opportunities for work...

I have an Asterisks PBX and a Vicidial predictive dialer and I need help configuring these servers and some special functions that I need the PBX to Show Local Caller IDs when calling Local area codes. I also need help with recording which of my call back number(s) the inbound callers use to contact us. We have some code to use our Asterisks PBX to recognize the inbound callers ID and pop up their Caller ID data and all information we have in our data base to know which agent spoke to the caller and what notes we have in the db for this potential client... I would like to speak to some knowledgeable programmers to and assign some tasks to know who can help us with these servers and programs long term.
