| 01/2017 - | Facebook had shut down the Parse, after that Community launched the Parse
Server as open-source, and this was a big opportunity for small companies to use one of the strongest backend service for free
Consequently, I was given the opportunity to participate as Migration Engineer at one of these small companies to implement Parse as backend on AWS platform
My responsibility was to create VPC the role of which was to configure and secure Web
Services. Creating Security Groups and allowing only port 443, installing Apache Server and configuring to point to Parse Server
Creating Cloud Front to reduce latency for customers around the world were some of my duties. Parse Server has a built in MongoDB but is not sustainable, so I had to create a separate MongoDB in AWS which point to Parse Server and that is by configuring node

| 05/2011 - | JSP, BEA WebLogic Server Inmarsat is one of the pioneering companies that provides mobile satellite communication. Because of its highly confidential nature, I am not allowed to explain the HLD of the Inmarsat network, but as a Deployment Engineer my duty was to maintain servers starting from CAR to AAA servers. Most of the servers are on RHEL 6.2 and where constant maintenance is and upgrade for security are crucial Liferay is build up by big amount of JSP applications and is upgraded upon customers' request i.e. new features, resolving bugs and deploying ear files on WebLogic servers Before upgrading or resolving issues testing in a lab environment and proposal for MOP is of key importance in this process. After undertaking these steps, my task is to present the procedure and proposal to the Inmarsat Engineering team for approval/feedback. Because of my previous knowledge on ASR9K routers my responsibility has expanded to configuration of SVN and APN on ASR5K Since there are more than 220 servers I had to find a better solution to complete some tasks such as upgrading/installing and configuring firewall etc and the solution I figured for tackling this issue was by creating my own Python scripts Deployment Engineer |

As a Network Engineer I had to configure Iups, Iur, Iub traffic towards RNC and SGSN. In partnership with Tellabs, AT&T agreed to use Tellabs 8605 to increase the network's bandwidth. Configuration of 8605 was done by increasing number of T1, DS3, OC3, OC12 and OC48 from RNC towards Tellabs 8800. Plan to configure and design and increase the amount of ports was done by utilizing a number of Mobile Phone users in the regions. So, AT&T sends us every week a highly detailed traffic usage based on the region and relying on this I had to configure and to implement in that particular region Glossary Term Definition Iups Is the interface between the UMTS RNC (Radio Network Controller) and the SGSN Iur Is the interface between RNC's RNC Radio Network Controller Iub Is the interface between Node-B and RNC SGSN The Serving GPRS Support Node MEAS Mobile Ethernet Access Service PGW Packet Gateway Rx Interface towards PCC (Policy Charging Controller) PPI Promoting and Pricing Innovation LDAP Lightweight Directory Access Protocol GGSN The Gateway GPRS Support Node SGSN The Serving GPRS Support Node SGW Security Gateway MME Mobility Management Entity UTRAN Universal Terrestrial Radio Access Network VPC Virtual Private Cloud LTE Long Term Evolution AWS Amazon Web Services ISP Internet Service Provider NMPR Network Migration Planning Report ANRS Amdocs Network Rollout Solution System CAR Content Access Register AAA Authentication, authorization, and accounting MOP Method of Procedure JSP Java Server Pages HLD High Level Design PSTN Public Switched Telephone Network Network Engineer |
