RoviSys - Automation and Information Solutions May 2023 – Jan 2024 Systems Co-op Holly Spring, NC

• Successfully migrated legacy PLC 5 code to Studio 5000, ensuring seamless integration and eliminating code errors, resulting in enhanced system reliability and performance.Proficiently debugged and troubleshooted code, addressing critical issues to improve system efficiency and minimize downtime.

• Expertly set up Remote I/O modules, establishing connectivity with the controller and configuring hardware components using Studio 5000, optimizing data acquisition and system functionality. Played a pivotal role in the development of Human-Machine Interfaces (HMIs) using FactoryTalk View ME, providing intuitive user interfaces and enhancing operator control.

• Collaborated in the development of a Functional Design Specification (FDS) for a project with CAVA company, outlining the setup of OT servers and the installation of Rockwell software on Remote Desktop Servers (RDS). Actively participated in FATs and startup activities, guaranteeing that control systems met client specifications and performance expectations.

Visakhapatnam Steel Plant - Wire Rod Mill Jun 2021 – July 2021 Technical Training Intern Visakhapatnam,India

• Overhauled equipment in the wire rod mill division to check for gear and seal lubrication and maintenance. Reassembled the assembly lines and thoroughly examined large-scale industrial equipment.

• Used lean manufacturing principles to develop, evaluate and improve gear manufacturing methods and kept the gear values within a 98 percent accuracy range to boost the productivity of steel wires produced by the wire rod mill.

• Validated the results using the machinery’s manual and gave a comprehensive presentation to the expert assistants on the data acquired from my findings to boost the production of the product by about 15 percent. Projects

Transshipment Delivery Costs Optimization Python, Linear Programming(PuLP),Logistics December 2022

• Designed a Linear Programming model in Python that allows for the definition of the decision variables and objective function to solve with parametric constraints was created using the PuLP library, together with the Numpy and Scipy packages to replicate the essential functions used for calculating distribution costs in a manufacturing facility.

• Implemented visualization programming approaches such as the Seaborn and Mathplot libraries to build various plots to determine the flow of inbound and outbound manufacturing plant costs. CFD assessment of peformance of Two-stage ejectors ANSYS Fluent, Autodesk Fusion 360 January 2022

• Performed a comprehensive case study on the performance of single-stage and two-stage air ejectors used in combat aircraft. Developed a two-stage ejector with a maximal entrainment ratio that is about double that of a single-stage ejector at 1.48 bar pressure and a high temperature of 813 K.

• Diagnosed findings of the two-stage ejector are shown, showing an efficiency of around 86 percent more than single-stage ejector in terms of velocity contour, pressure contour, temperature contour, Mach number contours, and entrainment ratio.
