  • Avid self-learner. Please see my blog for personal data science projects.
  • Extensive programming in Matlab and Python.
  • Strong team player and team building skills. Strong communicator.

Work Experience

Mobile Action       San Francisco, CA       2016-Present
Consultant, Data Analyst

  • Analysis of mobile app usage data to understand top features and indicators that attract user acquisition.
  • Development of machine learning tools to provide market forecast for a new app.

Croweer Inc.       San Jose, CA       2015-2016
CEO

  • Started my own company that targeted the development of an on-site and online English learning system using the latest neuro-cognitive learning techniques and a fast nonlinear curriculum with special focus on language production.
  • Successfully tested developed system on-site on two groups of adult English learners.

Western Digital Corporation       San Jose, CA       2008-2015
Staff Engineer, Advanced Channel Group

  • Main responsibility was the development and support for the self-servo-write channel technology in Western Digital hard disk system which involve the estimation and prediction of head-positioning on a data track.
  • Development of new features, ownership of the self-servo-write technology spec and the technical validation spec for various generations of read channels. Direct support and coordination of vendor support for all issues.
  • Testing and development of testing tools in Matlab for self-servo-write features.

Broadcom Corporation       San Jose, CA       2004-2008
Principal Scientist, Read Channel Architecture

  • Main system architect for the signal processing of the servo data channel. Duties included developing DSP algorithms, running performance simulations, writing a design spec, and implementing bit-true fixed-point design in C++/Matlab for RTL verification for the servo data channel for various platforms.
  • Issues worked on in servo data channel (baseband PAM) design include: reliable preamble detection (i.e., locating the servo data channel preamble on the disk), sync mark detection, signal polarity detection, CTF and FIR equalization and optimization, timing and gain acquisition with initial startup, signal interpolation, data detection, waveform coding for reliable data detection, error correction coding for servo data, performance quality metrics.

Agere Systems       Allentown, PA       2000-2004
Member of Technical Staff , Read Channel Architecture

  • Member of the read data channel team contributing to four generations of read channel platforms.
  • Projects: Fixed-point implementation and verification of noise-predictive maximum likelihood and parity post processor blocks, error event classification and analysis, investigation of optimal partial response targets, improved sync mark detection for the servo data channel, constrained digital FIR (linear regression) implementation for the servo data channel, improved phase and frequency acquisition for the servo data channel.
