- Student helper to PhD candidate working on "MultiPath Transmission Controle Protocol (MPTCP)". -Simulaltion of routing networks using INET Framework ( OMNeT++ Component based Network Simulation using NED-The NEtwork Description language) to test the experimental protocol "Multipath TCP". - Tutor of the lab exercises for the subject ”Communications Network 1” for bachelor students. - Configuration and maintenance of the networking lab.

- Part of testing and QA team as a tester for GSMA JOYN (RCS-e based application). - Verifying test environment under GSM/UMTS, LTE and WiFi networks. -Verifying the performance of IMS protocols (SIP and related protocols). - Used HP Quality Center and an inhouse resource management tool for test life cycle. - Finding defects, taking logs/traces, retesting and defect tracking/management with OEM teams. - Coordinating GCF tests with the OEM and the test lab.

- Testing of the Transport Software for the NSN Flexi Base Station(LTE/UMTS). - Collaboration with the developers in India remotely for defect management. - Setup, maintanance and firmware download/update for the Tranport modules. - Analysis of the Transport Protocols (LTE/UMTS) using Wireshark. - Extending Wireshark dissector code (in C language) for Transport Protocols. - Lab maintanance and management of the DHCP and the NFS Servers.

Developed a tool to detect external Electromagnetic Interference (EMI) effects on the MagTrak (Nuclear Magnetic Resonance tool used in Oil & Gas industry). - An SDR (software Defined Radio) served as the receiver. - A Magnetic Loop antenna and Current Clamps served as sensors. - Matlab and C++ SDK were used for simulation and presentation of the results. - Used Design of Lean Sigma tools and practices, as my supervisor registered my thesis for his Green Belt certification.

- Co-Authored the technical section of the successful project proposal. - Authored the RF and BSS Technical Audit Report and Checklists for GSM/UMTS sites in term of Capacity, Coverage and Installation Quality. - Trained the Technical Audit teams in field and in office. - RF Optimization for GSM/UMTS sites. - RF drive tests for KPI analysis, sector swap, Hopping, Rx Quality, Voice Quality, Antenna Tilt, handovers, GPRS and Edge.

- Microwave Transmission network planning using Path Loss tool. - Microwave links (SDH/PDH) and BTS installation, commissioning and media connection to GSM PLMN to turn the site status to ON AIR. - Quality Acceptance from Vendor and Operator, resolving issues during acceptance. - Performance and functional tests of the communication equipment (Microwave Links, Routers, switches).

- Conducted Line of Sight surveys (TSSR) for microwave network. - Hand-on experience with communication equipment (Routers, Switches and Microwave links). - Training with technologies and equipment related to Wireless networks, IP networks, E1 networks, SS7 Networks.

- Master Thesis: “Development of a Path Diversity Control Algorithm as a Path Management enhancement in the linux implementation of the redundant Multipath Transport Control Protocol (rMPTCP).”

- Bachelor Thesis: “Simulation of Target Tracking Algorithms through a Pulse Doppler RADAR.”
