Role: Senior ATG Developer

ATT.COM is AT&T’s B2C application where individual customers primarily shop for wireless devices, plans, services & accessories. The platform serves as a doorway for various items that AT&T sells on their website such as wireless, internet and uverse. Other than shopping as a first time new customer, one can even add a line or upgrade his existing plan.

Project: IPDSL

HardRock serves as a viewpoint for internet plans whereas URock is where one can actually buy them. HardRock, being an isolated platform, primarily focuses on wireless (cellphones), whereas the interface to URock is very static. All plans are displayed to every customer, even if he’s not qualified for one after an eligibility check. This project would enable customers to view only the plans that he’s eligible for in HardRock.

Achievements: Asked and got clarified critical questions from business that brought new hidden scenarios to light and enabled to re-scope the project and re-define timelines.

Responsibilities:

Enable dynamic user segmentation within the CQ engine in accordance to user eligibility qualification.

Enhance the check eligibility logic to consider IPDSL and VDSL users as separate groups and return only the qualified internet plans in each group.

Project: Super Folder

After introduction of Adobe Day CQ in eCom, every developer was facing challenges in their day to day activities to bring up their local environments and start working on their tasks. A concept called Super Folder was proposed which would enable one box to setup a full-fledged working environment and others could download it via an installer to have a readymade environment in their local boxes.

Achievements: Got identified as the sole resource to maintain and enhance Super Folder.

Responsibilities:

Maintain and enhance Super Folder to make it more efficient and configurable for diverse project needs.

Provide dedicated support to ALL developers in resolving ANY local environment issues.

Project: HardRock Phase II

ATT.COM serves as a gateway to different types of products sold on the website. This project was launched to solve two primary purposes. First, enable a platform for the birth of a common cart i.e. customers can buy any product under a single umbrella and second, introduce a new sophisticated content management system that would take enable business owners to perform daily content push instead of the developers.

Achievements: Proposed and implemented pipeline chain logic for cart compatibility logic to which the architects remarked ‘Wow!’

Responsibilities:

Rewrite the add-to-cart framework from scratch to host new business logic.

Develop a cart conflict framework for devices that can be mirrored for other product types.

Have the atg code integrate with the newly adopted CQ framework.

Role: ATG Feature Lead

Premier is AT&T’s B2B application where business customers login and shops for mobility and wireline items as permitted through their roles. It integrates with around 50 different external systems in order to achieve its functionality. Premier is a critical financial application for AT&T mobility and yields majority of the online revenues.

Project: SBS 3.0 Phase II

The second phase of the SBS project comprised of enhancing the sale of wireline products on the site. It also introduced ala-carte shopping i.e. shopping components of the wireline bundle instead of buying the whole bundle together. Hence it introduced new standalone products, mini bundles, shared web hosting & Tech Support 360 products.

Achievements: Come up with the idea of relationship model and successfully implement it.

Responsibilities:

Implementing a relationship model to hold different kinds of relationship with the working line of service group to another line of service group either in cart or already purchased previously on account.

Understand split order requirements and functionality and design relationship model in the best way to simplify the process.

Implementing availability of wireline products based on the customers service address.

Project: Content Provider Performance Enhancement

There is a sophisticated framework built on top of the product catalog that delivers content to the various types of user. Due to the complexity of the business rules the framework was going through a major performance drawback and the main target of this project was to improve the overall performance of the site to at least 50%.

Achievements: Improved the performance of the device page by 4 folds and even the ATG out-of-box promotion’s evaluation process.

Responsibilities:

Came up with the concept of JSON objects along with another front end developer and implemented it successfully, minimizing repository calls to NIL from the jsps.

Worked on the idea of a new filter framework whose job at a very high level are: calling a retrieval framework, caching content with a unique key, call filter which in turn calls filter tasks.

Implemented a very flexible logging framework that details which task filtered how many and which items.

Took advantage of ATG’s repository cache to build a global cache while server starts.

Globally cached promotions so that it takes minimal time for their evaluation during a certain session.

Project: SBS Phase I

Premier used to be a mobility only platform. SBS introduced a new era to Premier delivering its customers the flexibility to shop for wireline products (mainly bundles) and add wireline or wireless boltons.

Project: Checkout Refactoring & Performance enhancement

Due to lots of developers working on several functionality and releases the Checkout and LOSG initialization portions of the code had grown ugly and out of control. The major target of this project was to put a few extensible and scalable frameworks in place so that the code remains organized and under control.

Achievements: Implemented a generic framework to copy any object from VOs to repository using ATG Dynamic beans by implementing a common interface.

Responsibilities:

Came up with a generic validation framework that can report most types of form exceptions to the client but was not accepted by the architects due to certain drawbacks.

Took charge in persisting all contact information in the checkout flow by implementing a generic model to persist user inputs to the repository via a copy utility that takes advantage of dynamic beans to copy selected attributes from one object to another.

As QA team was relatively new to the project with minimal knowledge of the application, performed end to end QA testing identified defects and fixed relevant ones.
