customers.

RESPONSIBILITIES: Main role: Senior java developer and as a agile team

member, I was involed in the whole life cycle of multiple in house

projects:

Meet client to capture requirements

Architecture and design and confirm base line architecture with client

Estimate time of backlog and report project progress

Release management and creating deploy-able release for the client

DB development (queries, procedure, function ) and and some DBA tasks such

as backup and restore, create schema, tables pace

Lead teams of software development (2-3). Our team resources were very

flexible. when we had a big task to develop, a Senior developer took the

issue and up to availability of resources, he split the task into small

pieces and assign it into other developers and he was responsible to

Projects

Project: Re-factoring existing legacy application to use AngularJS as

presentation techniques and Service Oriented Architectures in the back

end.

Year: 2012, 2013, 2014

Role: Senior java developer

Technologies: JAVA/J2EE, Hibernate 3, Spring 3, Apache Subversion SVN,

JSON, AngularJS,JSP,DHTML,CSS, RESTful Web services by Jersy Eclipse

Indigo, Jenkins, Maven, Oracle 10, PL/SQL, Weblogic 10, LDAP, Linux

Worked with UX Designer and Senior Software Developers to re-factor our

main enterprise application(DA-Desk) . The old application used XSL/XML in

presentation and EJB 1 and processors and session beans in business layer.

We re-factored the application into Presentation, Business Service and DAO

layers. Jersy Web-service frameworks used in presentation layers that

interacted with AngularJS in JSON format, on front-end to view and alter

data. Spring IoC container used for instantiating, configuring, and

assembling beans and services. Spring AOP used as transaction manager for

the service layers' methods that interacted with Oracle data base.

Hibernate 3 used in DAO layer to save/retrieve data.

Project: A Web-Services application to expose our Data Model to external

application

Year: 2011, 2012

Role: Senior java developer

Technologies: Spring Web-Services, XML Schema, JBoss AS 7,JAXB, Hibernate

3, Hudson, SVN, Maven, JUnit, Unix, Oracle 10, SQL Developer .

We had several in house applications required to access database schema and

directly queried the database. I worked with a Senior Software Developer

to design and develop to expose our data model through a Web-Service

application. The application designed into End-Point, Service and DAO

layers.

Spring IOC 3 used for instantiating, configuring, and assembling beans

and services and Spring-Web services used to expose contract first web-

services to external applications. In DAO layer Hibernate 3 was responsible

for retrieving data from Database. External applications were able to call

a service and pass criteria to filter result and even include which part of

data from the model they need to minimize network traffic. To test this

application, spring integration test were used.

Project: Port point

Year: 2011

Role: Senior java developer

Technologies: WEKA, RapidMiner, Machine learning, Neural Net,Evolutionary

Algorithms

Cost and Time Estimation of shipping using Historical Data Several

algorithms and statistical methods (Neural Net, Kstar, ..) used in this

project to find the most accurate method to estimate the cost and time of

shipping for each port in the world( by WEKA and Rapidminer java api is

used as method implementation).

I worked on this project from very beginning to prepare data-set and did

research on how to apply evolutionary algorithms to to estimate the cost

and time of shipping for ports in the countries.

Historical shipping data used to train this system on daily basis and

the best model save into Database . This model used to estimate the cost

of shipping for particular set of parameter.

Project: Integration Application

Role: Senior java developer

Year: 2009,2010

Technologies: Spring,EJB,Hibernate, JMS,Web-service (SOAP,REST),junit

/cactus, Weblogic as server.

Our customers had different technologies to communicate with external

applications. The goal of Integration Application was to provide an

application that supports various communication technologies like JMS,

Web-service (SOAP,REST),HTTP . This application was a

communication channel between our main application and external world.

Hence this application was being changed and re - factored

frequently, a test application was created using junit/cactus to

automate testing of integration application.

I worked with a group of senior developers to design and develop this

application. Spring IOC used for instantiating, configuring, and

assembling beans and services and Spring-Web services used to expose

contract first web-services over http to external applications.

Communication between this application and out main enterprise application

was through JMS messaging service.

Project: Enhance,Maintenance of DA-Desk application

Role: Senior java developer

Year: 2006,2007,2008

It was a web application(J2EE/JAVA) that accesses data in a distributed

environment (source of data,can be Web Service

from java(axis) or .Net C# web service, xml file or a socket, and database

ORACLE/SQL Server ) . it was built on a frame work that access data from a

data access layer (we had Shifted to Hibernate,latest Object relational

Mapping Tech ), this data access layer accesses data from different kind of

Dao's (Web Service DAO, XML DAO,Oracle DAO, SQL DAO ).The application

developer, access the data from data access layer, and no aware of real

source of data.

I worked as a software engineer on R&D and design and developing of

architect as a single ear file and multiple war files, in order to use each

war file as a plug and play module. Each war file will handle each sub

projects inside. Excellent usage of J2EE design patterns and practices.

Major war projects are: Clinical Documentation, Orders, Chart, Dialog

Search, Cerner (base web-context), Messaging, etc .

I worked on building up the chart module, which contained all the

information of a patient, in a physician's

Perspective, like Lab, Medication, Blood Product Admin, Radiology,

Cardiology, Other Diagnosis Reports, different physicians notes, Allergies,

etc.

Module-documentations: Physicians could create different notes on a

patient's diagnosis; send to other physicians for advice, verification and

approval. This module was tightly integrated with messaging.

Projects

Project:Office Automation

Role: Software Engineer

Year: 2003

Technologies: Java, .NET, Webservice, JSP, JSTL, Servlets, SQLServer,

Oracle and JBOSS

It was a large J2EE /EJB Web application and .NET (C#) window application.

It was built on a object relational mapping using EJB frame work to

interact with database, and also had published its business method to

interact with data base by Axis Web Service (Facade pattern to minimize Web

Service method numbers) so .Net client was able to use java server to call

business method by Web Service, to access data in database, and also uses

Dime Attachment of Web Service to pass large document (like scanned

document ) between .net client and java server .

I worked on R&D and design and develop on communication between Java and

.Net (by Web Service RPC, Dime Attachments) and also implementation of

Fa ade pattern .

(Lower level layer API, working directly with web service, so higher layer

level called these API,

not aware of Web Service, so if in the future we wanted to directly use

.NET, to interact with

database, we only changed these low level API, and not whole .NET client).

I also worked on a object relational mapping using EJB. (CMP EJB are mapped

to database tables, u can use objects to Interact with database, without

directly connecting to database)

Project:Web report project
