Work History

Dec 2007 -- Current (Rogers)
Position: Enterprise Architect

SunGard was contracted by Rogers to define Rogers next generation data center (NGDC). The NGDC was based on defining services and service tiers. Services represent non functional application requirements such as RTO (Recovery Time Objective) and RPO (Recovery Point Objective). Service Tiers are a way of grouping defined services. Higher service levels have a lower RTO and RPO. The highest service level involved continuous availability with an RTO of < 5 minutes with no data loss.

SunGard was contracted to define infrastructure best practices that would enable the deployment of Rogers' NGDC based on service tier definitions and provide a roadmap from existing as-is state to future to-be NGDC state. Infrastructure best practices were defined for network, storage, database, mainframe, intel and unix based machines, governance as well as applications.

I was sub-contracted to SunGard and responsible for classifying Rogers' highest profile applications into as-is service tiers and to-be service tiers based on existing and future non-functional business requirements. I was also responsible for evaluating all application architectures to define infrastructure elements being used in as-is and to-be states. The evaluation included defining how application architectures would have to be modified and how much effort would be involved to take advantage of the new infrastructure for the future to-be state NGDC.

Nov 2006 -- Nov 2007 (Navantis Inc.)
Position: Chief Architect

Navantis is a Microsoft gold certified partner that specializes in systems integration and solutions delivery. Navantis has an impressive list of clients including Microsoft, OPG, Honda, Logitech and CIBC.

I am responsible for architecting, developing prototypes and proof of concepts proving the recommended architectures in a pre sales role for high impact projects. I am also responsible for mentoring architects and evaluating the architectures they create.

I am responsible for choosing technology that provides differentiation in Navantis' proposed solutions. I have been specializing in health care and programmable device solutions. The technologies I have been involved with include Biztalk HL7 accelerator, Sharepoint, MOSS, Microsoft business intelligence solutions, WPF, smart client, DSL and DataXtend(ORM).

I was the technical lead on a number of swat teams whose objective was to re-architect solutions to ensure they meet enterprise objectives in terms of scalability, availability, reliability, performance and transactional atomicity. I successfully re-architected multiple health care solutions to ensure they met the enterprise objectives. This resulted in significant performance improvements as well as scalability and transactional improvements.

July 2006 -- Nov 2006 (Yak Communications)
Position: Senior Developer/Team Leader

Yak Communications is a leading tele communications company. They have developed a residential VOIP offering.

I am responsible for leading the VOIP development team. I am responsible for the development of the recurring billing system, signup web interface and subscriber provisioning, call center web portal and reports server web interface.

June 2005 -- June 2006(Tucows Canada)
Position: Architect/Senior Developer/Team Leader

Tucows is the second largest Registrar in the world. Tucows also develops a variety of Internet products that are distributed via resellers around the world.

I was responsible for re-architecting, designing and developing a Blogging application created by Tucows (Blogware). The application was originally launched in a prototype phase in order to meet market demand. The prototype had quality, performance and stability problems.

The application was written using the Ruby language. A multi-tier architecture is used involving the following components. Radware load balancers, squid proxy servers, apache web servers, FastCGI, CGI services, an application layer, memcached services and Postgresql as the database server.

The re-architected production version is now scalable, stable and has exceptional quality. Performance now consistently meets or exceeds business requirements. The new architecture involved changes to database schema, tuning database queries, addition of squid caching, rate limiting/anti-spam support, usage of Ajax on front end services, addition of connection pools, modifications to fast-cgi support and adjusting the usage of farmed servers to handle client load and distribute traffic accordingly. Significant application re-architecture was also required to improve quality and performance.

I have also been responsible for adding new functionality to Blogware in terms of multi-lingual support using a gettext, UTF-8 and locale based solution.

Jmeter was used to ensure Blogware met is performance and functional goals under load and stress. Performance goals were achieved for the current client and database loads as well as meeting 6 and 12-month projections on database and client loads.

All new functionality has been delivered on schedule with excellent quality and performance. Blogware is known as one of the premier blogging services.

October 2002 -- June 2005 (Afilias Canada)
Position: Architect/Senior J2EE Java Developer

The Web Administration component was developed using the J2EE Struts Web framework. All deliveries for .ORG were made ahead of schedule with excellent quality and performance.

I am the project lead for the business intelligence group. I designed and created a data warehousing application that included full ETL capabilities as well as a Web based graphical interface used to interface with the data warehouse. I also designed and created management dashboard interfaces, a Web based report repository tool and a Web based billing tool. The ETL tool was developed using J2EE java technologies. The rest of the business intelligence tools were developed using a combination of Java and Perl technologies.

Multiple facets of the business such as external customers, executives, marketing, technical support, operations, management and development use business intelligence tools.

A critical factor to Afilias is that all internal and external products must meet and exceed certain SLAs. Therefore significant performance analysis is performed on all products. It is also critical to Afilias that the solutions are scalable, available, reliable, fault tolerant and redundant. Afilias provides global services that have to be 24/7.

November 2001 -- October 2002 (DestinyWeb Designs)
Position: Senior J2EE Java Developer

DestinyWeb Designs created a Web Based Student Registration System (SRS) for U of T Continuing Studies. This product has also been delivered to a number of other continuing education schools such as UCLA.

I was responsible for architecting, designing and developing SRS. SRS supports both a student interface as well as an administrative interface. SRS is a highly dynamic and configurable system that can easily be adapted to differing school environment depending on their requirements. SRS supports an architecture that is internationalized and localized.

All components of SRS are developed using J2EE Java technology. The Eclipse IDE was used for development. SRS is developed using Apache's JSP based struts. The Web Server interfaces with an abstracted business layer using EJB technology. The business layer interfaces with business rules as well as an Oracle database using JDBC (Data Access Object design pattern). I was responsible for the creation and implementation of use cases through all of the layers of the architecture. Use cases are first modeled and realized using Together J. Realization involving object diagrams, sequence diagrams, instance diagrams as well as state diagrams.
