Work experience

Operations Manager /Director - Finisar Actives, Fremont, CA: 2005-present

Manage operations of a factory which ships >3M units/qtr, 20 products and revenues > $10M/qtr. Successfully led a multi-functional team to transfer backend process from California to contract manufacturer in Asia.

• Set strategic operational goals (metrics: absorption, yield, cycle-time, on-time delivery, quality). Track performance against the goals and execute tactically if gaps arise.

• Perform capacity planning and address bottlenecks (labor, equipment).

- Increased factory throughput from 0.5 M units/qtr to >3M units/qtr.

• Improved cumulative yield of a key product from 3% to 10%.

• Reduced cost for a key product from $19.20 to $5.10 in less than 9 months.

• Achieved on-time delivery >99%.

• Implemented systems to improve quality –incl compliance with ISO 9K and 14K.

- Reduced returns/quality defects from 2000 dppm to <500 dppm.

• Reduced cycle time for a key product by > 40% .

• Coach team members to run lean manufacturing/continuous improvement programs.

- Improved visual inspection yield by 5%.

• Improved labor / equipment utilization by implementation of work centers.

• Increased transparency & effectiveness of operations by utilization of manufacturing execution data-base system (MES/CAMSTAR).

Sr. design engineer / Program Manager– (Finisar Actives, Fremont, CA) 2003 –2005

Transferred uncooled 1.3 um laser manufacturing technology from division in southern california to northern California in less than 5 months. This technology transfer is currently providing Finisar > $10M/qtr value. Developed two semiconductor laser products (revenues > $300K/qtr) & addressed yield issues.

• Finalized customer requirements – cost, technical specifications and schedule.

• Defined goals and timelines for different product lifecycle phases (EVT, DVT, MVT).

• Reduced chip cost by 10% qualifying second source for epitaxial wafers.

• Performed failure-analysis and implemented corrective actions to improve reliability of product.

- Improved ESD threshold (from < 500V HBM to > 1000V HBM).

Product Engineer - (Demeter Technologies, Finisar Corporation, El Monte, CA) 2002 – 2003

• Enabled better vendor management – implemented procedure to qualify incoming raw material.

• Improved customer focus: Performed failure analysis and provided responses to customer returns.

• Saved >$100K in Cap-ex by building characterization systems in-house.

• Improved product design by exploring impact of design parameters on jitter & mask margin of 10Gb/s eye diagram, S21, BER and RIN.

• Estimated reliability, MTTF of chip by performing highly accelerated aging tests (HALT).

Optical Engineer –Transmitter Design (Novalux Inc., Sunnyvale, CA) 2001 –2002

• Established high-speed test and measurement capability.

• Performed device modeling to extract key device parameters based on static/dynamic performance.

Skills

• Effective communicator with excellent problem-solving skills.

• Experience transferring technology/product between divisions / contract manufacturer.

• Clear understanding of product lifecycle management & new product introduction (NPI) process.

• Experience with implementation of statistical process control (SPC), and continuous improvement processes.

• 20+ yrs experience in semiconductor device design, processing & characterization.

• Familiar with Statistical data analysis (JMP) and design of experiments (DOE).

• Familiar with Manufacturing-execution-system (MES/Camstar).
