• Working on projects involving developing Smart 3D Printers including integrating industrial controllers, Process Optimization based on Feedback signal from machine and HMI enhancement.• Strong knowledge on tuning Servo motors for improved performance of the system. • Strong knowledge in PLC Programming (ladder, ST, Function BLock Diagram); implemented more automation functions. • Good experience in C# programming; Modified existing HMI to improve aesthetic appearance and added more functionalities to make user friendly machine interface. • Created a Python application for file editing purpose based on the printing process; reduced significant amount of time in generating gcode from the slicing software. The post-processing scripts are handled by python application which process those in few seconds. • Solid experience in 3D printing slicing software, Simplify3D and CURA.

• Conducted research on 3D printing of silicone with a suitable support material to print overhang structures.• Developed a new process to print silicone with plastics. Material extrusion based 3D printer has been modified to support printing of both silicone and plastics. • Adhesion between the identified support material (plastic) and silicone is determined. Based on this result, support material is identified.• Identified and analyzed critical printing parameters to print silicone with support material which include printing speed, minimum infill density for support material, flow rate, critical overhang angle and other printing parameters.• Addressed critical issue when part is printed without support structure even though the overhang angle of the part is above critical. Modeled and predicted print failure due to material properties of silicone and vibration due to the X and Y axis movement during printing using COMSOL.

• A virtual reality framework is used to assess the mission performance of a representative quad-rotor. Simulation for the endurance test of a quad-rotor is carried out using ROS (Robot Operating System) and BLENDER (3D game engine).• The performance assessment is carried out for three different range sensors by varying specifications of sensor and weight of quad-rotor.• The performance of quad-rotor is observed by flying it through a series of waypoints in a simulated environment. Created simple indoor environment using BLENDER

• Managed over 800+ servers of both physical and virtual machines across various platforms including AIX, Linux (RHEL and CentOS), Solaris and Windows.• Migrated AIX servers from IBM p595 to IBM p780 using VIOS concepts and managed resource using LPAR, DLPAR and HMC operations.• Hands on experience with NIM (Network installation Manager) administration where activities include TL upgrade, OS Migration and NIM server configuration for daily backups.• Managed Linux and Windows servers through VMware.• Installed and configured ESX 5.5 on HP servers in the new data center. Created resource pools and enabled v-motion on ESX host servers.• Converted physical to virtual machine and hot cloning of physical and virtual powered on machines using VMware vCenter converter during migration.• Hands on experience with installation, troubleshooting of VMware ESX, creating and managing Snapshots, Templates, Cloning VMs, Migrating VMs through Vmotion, iSCSI Storage, Networking, Datastores, vCPU, vMemory, vNIC.
