Work experience

Sep 2009Present


Data Realm Software Inc.

Analyzed, designed, and implemented a niche health care application for scheduling and practice management using python, django,  javascript, jQuery, mysql, and JasperReports.

Invented new heuristics algorithms for Kemeny ranking while doing research and business development on data-driven decision making.   Designed and ran computational experiments to compare these algorithms with optimal solutions from an integer linear program implemented with pyomo.

Sr. Software Engineer, Methodology Advocate


Developed the optimization algorithms for  About:Time® for Exchange Server using C# and AboutTime is an enterprise resource scheduling application that reduces costs and boosts customer satisfaction. Unlike calendaring systems, AboutTime finds solutions to complex scheduling problems in seconds. It is a web application that uses web services, a MS SQL Server database, and is integrated with Microsoft Exchange. Designed, developed, and executed stress tests that simulated load from concurrent users using Application Center Test (ACT).

Sr. Software Engineer, Team Lead

Knowledge Junction Systems

Team lead on ConciseMatch - a guided selling solution for telecommunications providers. ConciseMatch used a 3-tier J2EE web architecture with a Weblogic application server and JSPs, EJBs, and XML/XSLT. I was responsible for managing and mentoring 10 junior and intermediate developers.   I was also responsible for research and development of the core configuration algorithms.  These algorithms were prototyped using Ilog OPL Studio then implemented in Java.

Total Care Technologies

Played an key role in designing and developing the eXpert application for nurse scheduling. eXpert's Schedule Generation assists with creating a Staffing Model and Position Mix, as well as helping to generate optimal schedules that meet the demand while satisfying constraints imposed by policy, union contracts, and staff preferences.  Created prototypes using C++ Builder, participated in requirement and design meetings, and developed the algorithms to create a position mix using Ilog Solver and C++.

Ken and Peter did an outstanding job preparing for and delivering a great demo today!  All the comments during the call were extremely positive and our primary contact called me back after the conference call to say "That was a grand slam!" - P.M., CEO, Actenum

Ken is a mature, patient and professional Software Engineer. His attention to detail is evident across all of his work, from requirements analysis and estimation to coding, testing and documentation. - D.T., Application Specialist, eOptimize

Ken was an exemplary leader and mentor. As a team lead he defined and implemented the agile processes used by the development team.  - S.B., Software Developer, Knowledge Junction

Thank you Ken.  This is the shortest, clearest, and most complete security-related requirements document I've ever seen.  It's a pleasure to write test cases based on this document! - S.H., Quality Assurance, Actenum
