G Project Inc. (Goaloop.com)

09/2012 till date

Role: Chief Technology Officer and Chief Technical Architect

Location: 603 West 115 Street, New York, NY - 10025

Description:

I am currently employed at G Project Inc and I am responsible for the

development goaloop.com. It is a social networking platform with

functionalities ranging from basic user-interaction workflows to complex

monetary transactions. I designed the whole application from scratch and

developed it with a team of 5 developers. We launched the application last

month and currently the application is in invitation-only alpha mode. In

this job I donned several hats, including requirements gathering, building

tech-specs, design and development, work delegation and project management.

As with any other startup I had to keep a close focus on meeting deadlines

while building a robust software.

There has been many challenges in this role, but one of the biggest

technical challenges has been to find ways to keep the response time of the

application fast, even for content-rich pages. There are many parts of the

application which contain enormous amounts of data and it was a big

challenge to solve the issue of slow response time. I solved this issue by

designing and developing an in-house caching system.

Another wonderful aspect of this role is that I got an opportunity to look

through varied aspects of web application development. Finding an email

server which suits our needs, implementing the best SSL encryption for the

website, doing research and using various Amazon web-services (S3, EC2,

RDS, SES and so on), going through the documentation and then implementing

PayPal for monetary transactions etc are just a few examples.

Responsibilities:

. Requirement gathering: discussing the workflows with the founder and

other team members, give technical inputs, clarify technical issues

and challenges and come up with the UI workflows for best UX.

. Design the database for the whole application

. Design the backend architecture of the application

. Come up with tech-specs for the team.

. Hands-on coding

. Code-reviews of work done by other team members.

Role: Senior Analyst Developer

Location: 200 West Street, New York, NY - 10282

Description:

Worked at the Corporate Treasury Technology division of Goldman Sachs,

which oversees the funding operations of the organization. I worked on the

technology side of the operations, building tools for analyzing the data,

creating reports etc. This position provided me a view of the horizontal

slice of the firm's trading and funding operations. It required gathering

data from various trading divisions of the firm, consolidation and

transformation of the data for various purposes like regulatory reporting,

auditing, analysis and risk management.

Responsibilities:

. Building applications using Hibernate persistence API and server side

java programming.

. Data management using in-house cache management systems. Keen focus on

managing huge amount of data being sourced from all parts of the firm.

. Working on the front-end of the application built on internal

frameworks which use MVC architecture like struts etc.

. Designing and implementing various functionalities based on user

requirements specs from corporate treasury.

. End to end designing of the applications, starting from database

designing, in-memory cache management to backend and front-end

designing and implementation.

Citibank 08/2008

to 02/2009

Role: Consultant

Location: 283, King George Road, Warren, NJ - 07059

Description:

Worked on the development of applications, which dealt with Reference Data

in Prime Finance Domain. At that time the prime finance business used to

get the required data from multiple internal data repositories within the

firm. It also sourced data from outside vendors. In many cases, prime

finance platforms distributed reference data among themselves which created

duplication of effort. Reference Data team provided Ref Data as a common

asset and carried out the activities of sourcing, maintenance and

distribution of data in a centralized fashion. This effort provided

consistent prime finance reference data for client reporting and benefited

the business by avoiding conflicts, duplication of efforts and

decentralized data maintenance.

Responsibilities:

. Worked on the development of J2EE applications to retrieve, display

and update the reference data.

> Created a web application using Struts, Spring and Hibernate to

retrieve data from the web services and present it on the UI.

> Used spring beans and dependency injection techniques to

implement the struts action classes.

> Used Javascript and AJAX to get data for various sections of the

UI without refreshing the whole page.

> Used advance javascript libraries to do client side validations

and UI manipulations.

> Used weblogic to deploy the web services.

. Implemented web services to make the data available for internal

clients.

> Used AXIS and mule based internal web services framework to

implement the web services.

> Used Spring to configure the web services application.

> Used Spring AOP interceptors to implement calls to distributed

cache APIs.

> Used Hibernate to retrieve the data from the database.

> Used Weblogic to deploy the web services.

. One of the biggest challenges was to keep the response time to

retrieve/update the data because the large database size tends to take

a lot of time in serving the requests. We implemented distributed

cache to tackle this problem by maintaining in-memory caches to

retrieve the data instead of going to the database each time.

> Implemented the distributed Cache by creating various regions

and configuring indexing in Gemfire application.

> Implemented a multi-threaded Cache-Loader to load all the data

in the cache during startup.

> Implemented background multi-threaded daemon classes to keep the

cache updated and in sync with the underlying database.

. Wrote JUnit test cases to test the caching scenarios and to test the

programs to fetch data from it.

. Implemented an internal code release tool in perl and CGI.

. Tested and deployed all the applications in UNIX.

. Created cron jobs, monitored application performance and memory

availability in UNIX environment.

. Wrote stored procedures and sql queries in Oracle, to interact with

the database to implement business logic.

Environnent: Eclipse, Windows, SVN etc.

Technologies Used:

. Java and J2EE, Multithreaded Programming

. JUnit for writing test cases

. Spring, Struts, Javascript, Ajax, XML, Hibernate, Web Services

. UNIX, Perl, CGI.

. Gemfire as distributed cache management system

. Mule as the framework for web services

. Weblogic as the application server, Oracle as the DBMS
