The role involved

Working with the team on the drive to migrate the application, Customer Connect, from .NET 4.7 to .NET 6.

Making changes to a desktop application, Customer Connect implemented with Winforms, so that it can run on the .NET 6 platform. This involved removing any usages of older api(s) that are going to be removed in the .NET 6 platform. My particular task was to replace all usages of .NET Remoting with an open source package called CoreRemoting. The CoreRemoting project uses RPC internally but it provides a similar interface to that of .NET Remoting.

The application uses many services which we could not access directly therefore we had to mock these services using SoapUI.

Writing unit tests for each component we were working on, in my case it was the Cheque Scanner component.

Application Consultant, CIBC Equities Research Technology. December 1, 2014 – July 15, 2018

My primary role with the company was being responsible for all enhancements/updates to the Equities Research Information Publishing System and to be involved, end to end, in the SDLC. This entailed the following:

Working with the BA group to clarify all requirements and to define the scope of the changes to be included in the next development cycle.

Collaborating with my manager and other team members to identify the technologies we will use for the changes and to provide a realistic estimate of the development effort needed for these changes.

Implementing the changes together with other team members.

Ensuring that changes made in GIT are properly coordinated and labelled.

Making sure the tables in the database were properly indexed and scheduled a task to rebuild the indexes. Ensuring the queries in the stored procedures were using the indexes.

Check in on a daily basis with the development team to ensure that we are on track according to the given time estimate and what are the challenges that could possibly push out the estimated time of delivery.

The Agile methodology was employed, and daily questions/answers were maintained in Teams.

If any changes to the delivery date, update the BA team so that the business is aware of this change.

Upon completion of development, coordinate with the support team to move the changes to the UAT environment.

Send out a list of all features and/or fixes that are being addressed in this cycle, to all relevant groups.

Upon the QA team’s approval of the changes, coordinate with the support team to implement the changes into production within the appropriate window.

Coaching new team members to bring them up to date with the system.

Used SSIS for database jobs that moved data from the working set tables to the published tables. SSRS was the reporting tool of choice.

The system is an end to end solution for the authoring and publishing of equities research reports and has the following components:

Authoring

Implemented this application using Winforms and a MSWORD Addin, this tool enables analysts to create and route equities reports into workflow. The Addin provides a sophisticated data entry screen that retrieves the most recent market data to insert into the report and it also allows the author to modify this data as necessary, bullets and charts are also inserted from the data entry screen. The analyst can then choose, from an approved list, the vendors to which the reports will be distributed via SFTP.

Convertor

A windows service implemented in C# that converts the report, created by the Authoring component, into a PDF and other formats such as RIXML when the report is routed into workflow. The formats into which the report is converted are dependent upon the vendors that is chosen when creating the report. Used the MSWord API to manipulate WORD documents and the iTextSharp library for the PDFs.

Workflow

The workflow component is an internal ASP.NET website, written in C# and using Bootstrap 3.4.1, with the following functionalities:

Assigning the report to editors for review, editing and approval before publishing.

Viewing the PDF version of the report.

When securities covered by the report are flagged by compliance, the report can be assigned to the Compliance group for approval.

Publishing the report.

One of the projects that I worked on was to replace the legacy workflow frontend using Angular 7 re-using the existing services.

Transmitter

Upon publishing of the report, the transmitter windows service, implemented in C#, will then transmit the report to the external vendors in the configured format and this is done via SFTP. All SFTP destinations and accounts information are configured in a SQL database.

Market Data Feed

A scheduled task that invokes a WCF service in order to retrieve the latest market data from Thomson Reuters data feed service. The data retrieved is then stored in a SQL database that is then inserted into equites reports upon creation, the latest market data is also used to create price charts which are inserted into the reports.

Compliance Feed

Each covered security has a legal compliance attribute and this attribute is updated on a regular basis by a feed from the Legal Compliance group. This is implemented as SSIS packages triggered to execute at regular intervals. The nature of the legal compliancy attribute is visible when the reports are routed into workflow.

Price Chart Processor

Another scheduled task implemented in VB6 that calls a third party windows service, passing in the market data parameters, to generate historical price charts for covered securities. These charts are then inserted into the reports at a pre-configured section. The market data parameters that are sent to the third party service is taken from the SQL database.

Senior .NET Developer/Team Lead, Global Credit and Collections (i4Quality Software Solutions) March 2010 – August 22, 2014

The company is essentially a debt collections and call center service provider for various credit institutions and telecom companies. During my tenure at the company I performed several roles which are summarized below:

Collaborated in the design and implementation of an automated file processing system. The file processing system consisted mainly of services implemented as windows services hosted WCF services that performed the following tasks.

Downloading of new collection accounts files from various financial organizations. The layout of the files were mostly defined by the financial institutions and third party service providers such as AMDOCS.

After downloading, the files are validated and transformed using biztalk as per clients specification then loaded into a pre-processing queue by a file loading WCF service. The WCF service also queues a job to process the validated contents of the incoming file.

Another WCF service then picks up the queued job and invokes a client specific processor which then imports the new collection accounts into the company’s CRM system, applying the appropriate commission rates, letter plans etc…

The accounts are then worked on by client services/collections personnel and any activities, such as talking to the customer and payments, will then be reported back to the originating financial institution.

In order to report such activities, an orchestration engine Active Batch, invokes client specific reporting processors that will output all activities into files which will then be uploaded to the originating institution. The layout of the reporting files are defined by the financial institution and third party service providers such as AMDOCS.

Generation and uploading of Avaya Predictive Dialer campaign file to a secured FTP location that is configured on the dialer.

Downloading the campaign dialer results file and applying notes to accounts, within the company’s CRM, which describes the result of dialing each account. This could be answered, answering machine etc…

Collaborated in the design and implementation of a Debtor website replacement

This legacy site was developed using MVC 4 and the ADO.NET entity framework and SSL enabled. The frontend of this site was then re-implemented using Angular 7.

It allowed debtors to view their account balance and also gave them the ability to submit post- dated payments with their banking information. This information is all encrypted when stored in the database as per client’s compliance.

The site also allows debtors to update their information such as address, phone and email.

Team Lead for a project to provide a Telecom client in Panama with workforce management, CRM and reporting tools.

Designed and collaborated in the implementation of a new case tracking application for the Telecom client, this application was a replacement for the legacy case tracking application that was implemented using Winforms. This desktop application creates and tracks the progress of tickets for technical difficulties with customers’ post and pre-paid cell phones. Technology used to create this application is WPF using the MVVM model and SQL server 2008 as the database server. Included in this phase of the project was the migration of existing active tickets from a legacy system into SQL server.

Designed and collaborated in the implementation of another new desktop application that tracks the call center’s workforce planning and efficiencies, in near real time, for incoming/outgoing calls. This application was also a replacement for the legacy Winforms app that was being used. Technologies used in the development of these applications were WPF using the MVVM model, SQL server 2008, Oracle and Informix. Unity Framework was used as the Dependency Injection mechanism to access SQL server, Oracle and Informix.

In an effort to standardize document and content collaboration as well as to implement best practices throughout the development life cycle, participated in the design and implementation of the following.

Created and administered portals using SharePoint 2010/2013, to track requirement and design specifications.

Created a custom site template and master page for the Software Development portal and also customized the DataFormWebPart to include items from an external issue tracking system.

Migrated the entire sharepoint site from version 2010 to 2013 using the Sharegate third party tool.

Implemented a build server, using Cruise Control, to do regular builds and unit tests on a common libraries solution.

Team Lead, T4G Limited, Toronto March 2004 – July 2008

Project #1 – DESTINATION MANAGEMENT SYSTEM (DMS) – https://www.tourismbc.net

A large and complex web based application, enabling suppliers of tourism services and products, to register for marketing programs offered by Tourism BC. The application includes a program management component which allows TBC to create marketing programs on the fly to which suppliers could then register if they are eligible.

Designed the application with a layered architecture including the UI, Business Logic and Data Access layers.

The data store consists of a Live and Pending store and implemented in SQL server 2000.

Created a DTS package to import data from TBC’s legacy system into our SQL server 2000 environment.

Stored procedures were designed and implemented to access views instead of the tables directly allowing for changes to the underlying data model without significant changes to the Data Access layer.

Designed and helped to implement an auditing system which records all changes made from the application, these changes are presented in the UI.

Listing information collected from the supplier is first placed in the pending store and would then be subjected to a quality check process.

Designed and implemented Quality Check, Inspection and ‘To Be Contacted’ workflows, using K2 studio which are triggered based on specific events within the application.

Upon inspection and quality check approvals a task would then be triggered in the background which would then copy the listing data to the live store. Tasks were implemented using the spring framework and scheduled with a scheduler implemented as a windows service.

Tasks could be independently implemented and configured to be run by the scheduler in an xml file without having to modify the scheduler.

Designed and helped implement a publishing/subscription system to which specific events could be subscribed for and then handled appropriately. Subscriptions were configured in an xml file and could be done on the fly.

The pages in the application were associated with specific business object which were time-stamped and serialized into view state. Time-stamping allowed for an implementation of an optimistic locking mechanism which protected simultaneously updates.

Designed and helped to implement a shopping cart for the system which uses Moneris web services to verify/validate credit card transactions. All financial transactions, credit card and invoices, were then published to Agresso by ftp in file formats specified by Agresso.

The application was designed to behave differently based on the role of the logged in user. Roles included Product Service Coordinators (PSCs), suppliers, administrators etc. and were implemented in Active Directory as local security groups.

Designed and implemented
