PROFESSIONAL WORK EXPERIENCE

Aug14-Oct15, Valerus Field Solutions

Project Engineer

Interacted with midstream natural gas clients to assess project specific engineering and design needs in order to ensure that the assembly meets the design intent. Managed equipment sizing tasks to ensure compliance with API 688/618 pulsation and mechanical.

Designed custom made supports using Autodesk Inventor for process piping and skid mounted assembly and change process P&IDs. Reviewed BOM and progress of assembly with manufacturing shop to ensure timely delivery

Jul13-June14, C&J Energy Services

Mechanical Engineer

Recommended hydraulic fracturing fluid end design changes using ProE/Creo for increased fatigue life at high treating pressures.

Reduced inventory and maintenance costs by performing supplier change tests on triplex reciprocating pump components like valves, seals for endurance. Documented statistical analysis reports as per company standards

Achieved 60% cost reduction by retrofitting current product failed pump design. Interacted with operations and maintenance teams to troubleshoot onsite failures with oilfield equipment

Oct 12 – Jul 13, Onsite Caterpillar Inc. – Contract Position

Product Development Engineer

Experimentally developed tightening specifications for bolted joints in diesel engines, mining and material handling equipment using torque-angle transducers. Used RS 960 for data acquisition and Fastplot and DATK for data post processing.

Validated clamp load in bolted joints for mining and material handling application using Ultrasonic measurement technique (Minimax) to meet project goals with Caterpillar standard implementation procedure. Enhanced hands-on skills by conducting fatigue and bolted joints measurement using MTS Flex Test Controller and EDAQ data acquisition systems.

Lead investigation for on-field failures to identify client testing and validation needs. Recommended design modifications using DMAIC technique. Prepared technical report and presented design reviews to recommend cost effective solution.

May 11-Aug 12, Cummins Inc.

Mechanical Engineer

Newly design using Creo/ProE diesel engine power transfer components such as Gear Housings, Flywheel housings (major castings) using for various Industrial pick-up truck, marine and agricultural applications.

Completed assigned project goals and satisfy customer needs as per internal Cummins standards and implementation procedures.

Interacted with overseas cross functional design and project teams to identify and solve current product on-field DVP&R issues. Provided timely project updates by conducting meetings.

Designed and prepared fixtures using ProE required to conduct static and fatigue tests for validation in conjunction with the machining dept. Planned and coordinated experimental tests with lab technicians to collect basic strain, temperature and vibration measurements.

Performed reverse engineering on flywheel housings to experimentally determine safe fatigue loads on flywheel housings as a part of DFMEA process.

Validated engine valve train and power transfer components such as push rods, valve springs, flywheel and transmission housings for Dynamic Fatigue Margins, dwell condition limits, material Low Cycle fatigue limits and bolted joint design as per Cummins standards to be a part of Design Validation Planning and Report issue solving.

Coordinated non destructive failure analysis tests Magnaglo, Zyglo with Metallurgy department to inspect and analyze for crack initiation and propagation in major casting components as a part of DFMEA process

Used concepts in Statistical Process Sampling to reduce machining cost on surface roughness of fuel system injector clamps. Post processed data to identify and eliminate special causes and decrease process variability by plotting X bar and R charts in Minitab.

Presented project results in design reviews to promote projects in production phases. Documented results in a technical report format to as a part of company literature.

Jun 06 – May 07, Thermax

Mechanical Engineer

Design, Manufacturing and Testing of Industrial Flow Control Valve for Regenerative Cooling System -

Interacted with customers to identify root cause for Butterfly valve leak and propsed new concept Flow Control Valve (Poppet Type) having efficienct valve operating characteristics

Modeled new design concept using SOLIDWORKS. Manufactured prototype flow control valve using Design for Manufacturing principles for achieving 50 % cost reduction over existing designs. Performed hands-on testing in coordinating with testing team to verify the prototype design parameters

Aug 07 – Jul 08, Thyssen Krupp

Manufacturing Engineer

Managed day-to-day manufacturing activities - fabrication and welding to subordinate engineers and technicians. Worked with quality control team- scheduling hydro-testing and chemical non-destructive testing for industrial boilers, material handling applications

Documented orders initiated by the client and determined the impact of changes on inventory control of the project. Minimized project specific inventory using SAP (production planning and material) module

GRADUATE PROJECTS

Developed FEA model of 2D composite with contact elements for contact nonlinearity problem due to dynamic loading. Enforced periodic boundary conditions to predict composite elastic properties and stress analysis using node coupling commercially available ABAQUS 6.91 SE.
