- Analyzing the requirement specified by customers and drive towards a solut ion-oriented approach

- Prepared use cases as per project requirements and developed a design document with project specifics.

- Designed the individual modules using Java and struts. Used Servlets to design Java classes and JSP for the User Interface.

- Trained in Web Sphere Process Server tool and used it to design modules for applicat ions and integrat ing them to a solut ion. Management Analyst:

- Independent ly handled the Support division of the Global Leadership, Sales and Support team.

- Led a team of 4. Provided support for Business establishment in Africa. Academic Projects August’14 –December’15

- Development of Multi Layered Aggregate switch Data Center Network architecture using SDN – Thesis Project a. Developed a Mult i-Layered DCN with increased aggregate switch blocks using Mininet virtual network simulator and built custom topology using Python. Used SDN to have centralized control over the network. b. Scaled the virtual network vert ically and horizontally with 96 hosts in a server rack to perform the Delay-Bandwidth Analysis. c. Compared Mult i-Tier architecture with Fat -Tree to evaluate the bet ter network suitable for scaling.

- Network Virtualization using Software Defined Networking a. Collaborated with a team of three to implement Fast Failure Handling, and studied Load Balancing with capacity opt imizat ion using SDN controller (POX) and Mininet VM.

b. Used Python and Ubuntu OS to achieve SDN implementat ion. Understood the ONF standards and Open flow protocols.

- SDN Security – Defense mechanism for Port Scan Attack a. Developed a defense mechanism for Port Scan Attack using Python. b. Init iated Port Scan attack using Nmap and used shell script ing to init iate several commands simultaneously. c. Created a Network topology using Mininet and modified the SDN controller to manage the funct ionalit ies of hosts and the switches to detect malicious data.

- A Simple File Sharing Service

a. Developed a file sharing service where files are centrally located on server and shared among mult iple clients using C. b. Implemented an Inter VM communicat ion and file sharing service among two virtual machines.

- Simulation of Label-Switching Networks using NS3 a. Created and simulated a custom topology using C++. Analyzed and understood the simulat ion outputs. b. Examined the process of label switching in MPLS protocol using NS3 tool on Ubuntu.

- Implementation of Voice over IP (VoIP) using Session Initiation Protocol (SIP) a. Ut ilized a server using Asterisk Software and a few XLite phone VoIP users as client to establish call between them in Ad-Hoc Mode. Experimented call establishment, busy user, call on hold and call conferencing scenario between the server and client . Education:
