Work Experience

AEM Lead Developer

2017 - 2021
  • Re-implemented the order chat table for Shell MarketHub 1.0 Marine, entirely restructuring the marine lighthouse table, order details page, and views management functionality. I was awarded as the best individual contributor in 2018 (Q1).
  • Prevented multiple requests made to the AEM back end to fetch the same menu that JSON required on every page of the SMH. I used client-side caching resulting in page loads of MarketHub (except Hybris pages) faster by 750ms to one second.
  • Performed adaptive image renditions based on the size and location of the page. For all the heavily sized images, suitable images renditions were generated and used according to the size of the image container.
  • Built the integration in the AEM back end to use the Salesforce REST API for contact creation and updates on the contact flow, contact de-activation, and deletion for the project blaze. SMH uses Salesforce CRM through an API built with Apigee.
  • Re-implemented the Shell MarketHub login page through a new login and landing page to make it completely authorable.
  • Integrated in four AEM components, thereby allowing SMH to enable videos accessibility in SMH pages.
  • Implemented lazy images to decrease page load time by loading them asynchronously to the page load event.
  • Worked as a technical lead and developed the Marine GSAP integration project from January to March 2020. This enabled action status updates to flow from GSAP to Marine, reducing COS efforts.
  • Recognized with the best performing team award in 2020 (Q1) and SMH people choice award in October 2020 (Q4).

Shell MarketHub
Shell MarketHub (SMH) is a B2B AEM project with 50,000 users across 60 countries and 24 experiences. There are 143 sites in several languages. SMH is a B2B website where users from different businesses log in and purchase various products from Shell, like lubricants, oil, and fuel. Businesses that use SMH are eCommerce, aviation, marine, lubricants, and US fuels. SMH has an annual revenue of 18 billion.

My technical responsibilities included:
Development of new reports and widgets (for the US fuels business) and Sightly components, modification of old JSTL and JSP components, OSGi services, custom workflows, Sling schedulers, custom JCR event listeners, and Sling servlets.
Integration with NGAP and the relational database.
Integration of the following services with AEM (UAM): Salesforce CRM, microservices, SOAP web services, and REST services (Shell legacy applications exposing REST services or integration with third-party REST services.)

Development of modules for marine, aviation, and UAM.
Leading cross-business implementation activities for marine, aviation, blaze, and AEM/UAM CRs.

Wegmans Food Markets, Inc. is a privately-held American regional supermarket chain headquartered in Gates, New York. This project aimed to migrate to the AEM platform.

As part of this project, we started by identifying the base page and home page templates, recognizing the reusable components required to be developed apart from reusing the out-of-the-box components. We also performed integration with Target and DTM and handled content migration scripts to migrate their thousands of products and recipes.

Under Armour Brand
Under Armour, Inc. is a leading American sports clothing and accessories company.

UnderArmour brand was one of the most complex projects that Adobe handled. This project required a lot of customization of AEM assets functionalities to suit the client's requirements. We heavily customized AEM project creation, AEM assets search and replication functionality (activation and de-activation), and collections. We created a new site called "Vendor Portal" where only the published assets would reside ordered by brands and published date. Many custom workflows were designed to handle expired assets, automatically de-activating them from being published, moving projects to a different location based on the attributes selected while project creation, creating custom renditions when assets are uploaded, and more. Also, we performed integration with InDesign, making assets modified in InDesign automatically available in AEM and vice versa—a two-way synchronization.
