Software Engineer/Architect

Skills Used: Node.js , Meteor, Highcharts, HTML, JavaScript, CSS

Responsibilities:

QC Results was a project aiming to create customized forms, store data, and present stored data by utilizing statistical graphics.

Software Developer and Tester

Skills Used: Java, Multithreading

Responsibilities:

A simulation of Schroedinger’s wave dissemination over a two-dimensional space was performed by using multithreaded synchronization. A two-dimensional square bucket was assumed to be the water surface. To simulate wave dissemination over this water surface, the square was partitioned into N-by-N cells. Each cell maintained the height of its water surface. A wave was disseminated north, east, south, and west of each cell.

Confidential, Seattle, WA

Statistical Data Analyst and Researcher

Skills Used: Statistical Modeling, Regression Analysis, STATA, SPSS

Responsibilities:

User-satisfaction of a software application increases when system reliability increases. Two reliability variables, each with two levels, were utilized to explore this hypothesis in this project. An experiment was done by using Factorial Design. And a Regression Analysis was performed. Results showed existence of both main effects and an interaction effect. A negative correlation between user-satisfaction and the number of username/password failures was observed. User-satisfaction increased when number of defects decreased. Moreover, results showed a negative association between the interaction term and user-satisfaction. That is, user-satisfaction increased when two reliability variables, number of defects and the number of username/password failures, decreased jointly.

QA Engineer, Web Developer

Skills Used: Java, HTML, SQL, SoapUI

Responsibilities:

A web page which displays services provided and contact information was designed and developed for this tutoring firm. Java technologies were utilized. It was a small team.
