My Work Experience

Where I've interned and worked during my career.

Altair Integrated Services | Sep 2019 - Nov 2019

Blockchain Application Developer in Analytics & Data Management

Altair Integrated Services is a fintech startup that provides IT consulting services and top talent acquisition to insurance and private equity companies. Worked closely with Charles Link, Altair's vice president of Analytics & Data Management, to develop an innovative new data security product that uses blockchain technology to protect personally identifiable information (PII) from unauthorized access and alteration: • Helped develop product specifications, use cases, and system architecture. • Researched existing applications of blockchain technology to data security. • Tested blockchain network implementation coded in Python and Flask for proof of concept. Unfortunately, new funding priorities put our project on hold. #StartupLife

Altair Integrated Services | May 2019 - Aug 2019

Lead Instructor for Modern Application Development Course

Worked closely with senior software developers/co-instructors Christopher Cooper and Vladimir Berns to develop a course curriculum on modern application development. Team-taught our new 8-week course to Altair's college interns. Course covered cloud computing with Azure (Cooper, 1 week); relational databases with Azure SQL Database (Berns, 1 week); web app development with Python/Flask/SQL (Chapman, 5 weeks); and business reporting with Power BI (Berns, 1 week). Interns and instructors worked together to complete two capstone projects tailored to our client's business requirements—a time tracker web app coupled with data analytics reports: • Designed a normalized relational database (3NF) with 8 data tables and 7 join tables in SQL. • Wrote SQL database API using 3 views, 10 joins, 7 stored procs, and 3 user- defined functions. • Coded business logic in Python and wrote API wrappers for SQL using 5 ODBC driver methods. • Built frontend with 8 Flask routes/views, 2 Flask-WTF forms, 5 Jinja templates, and 9 CSS styles. • Created 3 Power BI reports to extract/visualize useful information from raw data in Azure cloud. • Graphed monthly costs by department/project/worker based on times tracked in SQL database.

Drexel University | Sep 2006 - Aug 2008

Visiting Professor of Computer Science

Course coordinator for Drexel's first college-wide Computation Lab, a three- course sequence taken by all first-year engineering students. Used Maple computer algebra system to teach computer programming, symbolic-numeric computation, scientific visualization, computer simulation, and data analysis. • Led a team comprised of a dozen faculty members and teaching assistants. • Expanded lab from pilot project for 70 students into college-wide offering for 700 students. • Integrated Maple TA into course to automate testing/assessment via online quizzes and exams. • Implemented robust Maple TA grading algorithms to eliminate manual grading of 2,100 exams.

University of Waterloo | Sep 2005 - Aug 2006

Postdoctoral Research Fellow in Computer Science

Collaborated with Maple co-inventor Prof. Keith O. Geddes to investigate the computational properties of Geddes series expansions via experiments in Maple. • Invented, classified, and named 139,656 different types of Geddes series expansions. • Laid groundwork for convergence theory of Geddes-Newton series for positive-definite kernels. Achieved first result by combining p = 48 univariate interpolation problem types with t = 10 linear integral transforms to generate C(p⋅[t+1]+1, 2) = 139,656 series types. Second result led us to series of research breakthroughs presented by Prof. Geddes in his invited conference talk at SNSC'08.

University of Waterloo | Sep 2003 - Aug 2005

Adjunct Professor of Applied Mathematics

Taught one science/engineering calculus course per trimester for five consecutive trimesters. • Gave lectures, held office hours, created exams, wrote solutions, supervised teaching assistants. • Received very favorable teaching evaluations and heartfelt thank-you notes from my students.
