• C, SAS (advanced macro coding), Python, picking up Ruby and Javascript .
• Strong UNIX shell scripting, SQL and ETL development with DBA experiences, and learning other languages as needed) to process large amounts of structured and unstructured data, Hadoop and Mapreduce.
• Management and implementation of database migration (including ETL) from Sybase to IBM Informix to Oracle, design and development of data warehouse and datamart to enhance Providian’s reliability and cost - effectiveness of risk assessment, as well as its ability to design and deliver a variety of tailored product or services to develop longer lasting relationship with customers.
• claims captures information from all doctors/providers caring for a patient with an accurate record of all prescriptions that were filled including dates of refills.
• EMR covers all patients (including uninsured) with rich data on lab results, vital signs, patient surveys, habits (smoking, etc), and problem list, etc.

EXPERIENCE:

Fullstack Software Engineering Student

Confidential

Responsibilities:

• Organizing full dataset files by route into folders for each Confidential and subfolders for each Confidential, and Inspecting records for errors and improper values.
• A record was labeled as invalid and discarded if it failed one of the following checks:
• For training of the SVM classifier, multiple smaller datasets were generated by a combination of subsampling and filtering by routes, cabin classes and request data ranges.
• For validation and training, each record was labeled according to the normalized price. Each record received 6 labels in total, each having either a value of −1 or 1.
• The corner case of the sign function returning 0 were interpreted as a label of −1.

Data Mining Algorithm Consultant

Confidential

Responsibilities:

• Dimensional data-reduction based statistical modeling. The model features data mining from high dimensional data by ignoring the not very important feature data elements and holding the principal data components. It clusters and considers data points in data space which are interacting with each other by some effect forces, by utilizing and leveraging on a data field developed and formed in the data modeling process.
• A "fermionic" behavior based marketing research model analyzing the long tail segmentation of Chinese ecommerce. Consumers in “long tail” are more like fermions particles (vs bosons) which requires much more personalized "space" (space address has three parts (location, momentum, and spin)), often exhibiting strong “crowd-avoidance” behavior pattern
• Confidential 's method works by projecting - ∇ f(x) on to the hyperplane tangent to the set of active constraints. By doing so it tries to improve the objective while simultaneously maintaining feasibility.

Owner, Family Business

Confidential

Responsibilities:

• Created a joint venture of a few families & owned and managed a portfolio of real estate properties: apartment buildings in Portland, Oregon, a motel in Sacramento, California, and single family homes in Brentwood, California. Microsoft Access consulting for other small businesses.

DBA(Informix, Oracle, Sybase, Teradata)

Confidential

Responsibilities:

• Managed multiple marketing databases and migrations with following major accomplishments
• Worked with the marketing department to design major marketing campaigns based on data modeling, for example:
• Constructed a data warehouse and front - end tools to allow data mining and segmentation analysis.
• Employed a dataset with historical trade line credit card information from Confidential, which included account characteristics such as age, credit line, and utilization, and used their one-year default rate to model future rates of defaults and their contribution to portfolio losses over time.
• Mapped out business logic and algorithms for various aggressive growth strategies involving new accounts, balance transfers and outstanding balances, as well as strategies aimed at attrition retention and account development.

Senior SAS programmer and analyst

Confidential

Responsibilities:

• Built and developed a team of DBAs, UNIX programmers, SAS programmers and migrated marketing department s customer database from Sybase to Oracle. Our system had to interact with existing tools such as Total System Services.
• Supervised the weekly and monthly updating and maintenance of data load operations.
• Supervised SAS programmers to code business logic and algorithms (mentioned in the prior section) adjusting variables such as balance transfers, minimum payments, interest rates, to increase customer desire and their motivation for building and accessing their credit.
• Managed a separate team of SAS programmers dedicated to the Providian s acquisition efforts of acquiring creditworthy consumers, including identifying and profiling of high - risk customers.

• Chronic patient cost analysis, incidence and prevalence rates for diabetes, hypertension, hyperlipidemia, and coronary artery disease; this analysis was used to support the actuarial and disease management departments.
• Database construction and statistics to develop chronic disease models aiming at the detection, prevention and ongoing management of chronic diseases, specifically using observational cohort studies to understand rates of disease progression, effects of fixed and time - varying risk factors, and the extent of heterogeneity in the course of disease. Epidemiology Analytics in the design and development of large-scale studies.
• Various experimental designs (Response Surface Methodology (RSM), Conjoint analysis): estimate the shape of the experimental response surface (contour plots) with a mixture of first-order & second-order models, with a relatively small number of runs while still expecting designs be orthogonal and balanced.
