SUMMARY:

• 10+ years of experience developing applications with expertise in migrations between frameworks, most recently angular/backbone to React.
• My core stack is using Javascript, Typescript, React, Redux, ES6/ES6, Vanilla JS, Axios, HOC, Redux Saga, etc.
• I am good at identifying optimizations with broad impacts for example, I started the practice of using SSR (server - side rendered) React on an expressJS nodejs server. I also specialize in build tool optimizations with webpack.
• Besides this I am also I maintain the CI build script files that trigger our unit and integration tests. I use bash, groovy, python and nodejs for my scripting needs depending on the task at hand.

Software Engineering Consultant

Responsibilities:

• Create a library of EXTJS components.
• Was primarily responsible for creation of an EXTJS custom grid that supported drag and drop.
• Created custom EXTJS Components leveraging the 4.2 version of EXTJS and styled them using SASS.
• Introduced modularity as a concept and encourage developers to leverage Angular directives for their re-usability and avo copy-paste of existing logic and markup
• Introduced the use of a javascript build tooling, specifically grunt to improve developer experience by automating the transpiling of LESS
• Worked on development of an internal CRUD application for user management and claim managemen
• Worked on the setup of the frontend of the application. Primary goal was to accomplish 3 objectives
• The first objective was to introduce modularity as a concept and encourage developers to leverage Angular directives for their re-usability and avoid copy-paste of existing logic and markup.
• The second objective was to encourage developers to avoid cluttering HTML markup with bootstrap classes and instead use custom styles on the markup that would then inherit the bootstrap classes as mixins in our LESS files
• The third objective was to demonstrate the benefits of unit testing some of the more complex elements in the code by implementing some logic using TDD and showing how it was possible to gradually refactor some of the existing code into more testable pieces of logic
• Designed directives for breadcrumbs, application notifications, dynamic form creation and custom field validation. All directives were built using test driven approach with the jasmine testing framework.
• Led the development of the project to deliver a new feature to enable mobile site consumers to create and manage ads to sell their car on autotrader.com
• Worked primarily in jQuery mobile development and JSF 2.
• The project was agile and driven by Jira. We used JSF 2.0 component presentation framework along with jQuery mobile.
• The goal was a consistent user experience across all mobile devices so I followed an adaptive rendering design pattern heavily in the styling strategy
• Used coffeescript to generate the js files and SASS for the CSS and incorporated a custom theme using jquery theme roller.

• Product Modeling and Management Applicatio
• Key contributor to the expansion of the application, developing many new features using Java, Spring Boot, Microservices, Angular, Hibernate, JPA.
• The main theme was TDD and agile. We incorporated Jasmine BDD testing framework for unit testing because of its excellent mocking api. I also used Sinon for its ability to create a fake server, it had a more fluent api for this than the extjs ajax simulation manager
• Introduced the use of DeftJS to make enhance the framework, we used the promise API along as the Deft ioc injector to make the code more modular as well as to help in testing with the ability to inject testable dependencies.

Full-stack Software Engineering Consultant

Responsibilities:

• My responsibilities were requirements gathering, user experience design, solution design and implementation
• I was responsible for a Transportation and Expense Procurement Reporting Applicatio
• Wrote both frontend and backend C# .NET 4.0, including stored procedures in TSQL and .NET webservices. Used PVCS for source control management
• Mentoring and training of cold fusion developers in HTML, JS & CSS. Most of this revolved around teaching EXTJS JavaScript framework since the company was adopting this for most of their internal applications at the time
• Wrote and proposed different architectural implementations to my supervisor that would make the code base more modular and follow SOLID principles, especially single responsibility because we had many instances of classes or modules that were doing too many things and global objects strewn all over the code.

Confidential

Software Engineer

Responsibilities:

• Tasked with upgrading an internal website used to gather, collect and share documents. This project consisted of primarily conversion from classic ASP to ASP.NET 3.5 framework however additional functionality and a new UI was also required
• I applied the use of DevExpress Gridview, among other DevExpress controls such as their upload control extensively in this project.
• Integrating the file upload control with the gridview’s CRUD functionality proved to be challenging but I was able to do this by disabling some default behavior and writing custom code. The JavaScript client-side API provided by DevExpress proved to be very useful here.
• I implemented grouping, filtering and search using client side JavaScript and making use of the gridview’s client-side API.
• For the UI, I customized a theme for the gridview
• The data layer consisted of data objects within our custom framework that I then tied back to the database (SQL Server 2008) by calling stored procedures.
• I cached some data using cookies and also server-side via session for optimization.
• I was tasked with the conversion of the Confidential Bank Statement reports to Confidential Bank Statement reports.
• I used DevExpress XtraReports reporting tool. I created a base class that would be used to derive all sub-reports.
• To encapsulate validation and data binding details, I employed the use of delegates, whose methods were overrides of virtual methods in the sub-report base class.
• For purposes of reducing the amount of code to be typed, I designed a helper class with static methods that included a recursive iterator that hydrated all sub-report data sources.
• I created scheduled services to be run for the generation of bank statements in .pdf file format from xml files, and the generation of print and digital media from the .pdf files.
• This project involved the automation of daily transaction processing. File watchers, statement and log creators, SQL stored procedures, and email messaging were all encapsulated in a web wizard
• Before this processing involved the manual execution of the stored procedures, emails had to be manual sent out and files copied and pasted manually.
• The ultimate goal is having a service run and only for a user to be alerted when there is an error but until the process workflow is finalized, a requirement was for a user to monitor all the steps. This is why a wizard was created.
