PROFESSIONAL EXPERIENCE

Samsung India Software Operations Pvt. Ltd. (www.samsung.com)

Sept 07 - Present

Samsung India Software Operation Pvt. Ltd. (SISO) is a subsidiary company

of Samsung Electronics Corporation. Samsung is a South Korea based

technology company involved in development of software for the mobile

devices and consumer electronics. SISO takes project from Samsung

Electronics, Korea and provides services and solution to them. Company is

also involved in developing and commercializing software for mobile phone,

consumer electronics and memory cards in India.

Project 1: File Explorer (My Files App for Tizen platform) Role:

Technical Lead

Tizen is an upcoming open source platform from Samsung and it's partner

companies. To make the SDK open for people/organizations and readily

available to the the OEM's all native application should be present in the

framework.

Responsibilities:

My Role in this project is more like an individual contributor as well as a

team lead/architect.

During the initial phase of the project, I had discussions with HQ to

understand the requirements. After detailed discussions, I made elaborated

SRS document. Once requirements were frozen, I had started with High and

low level design diagrams, including interaction diagram, sequence diagram

as well as class and interface diagram. Once all design elements were

identified, I and my team of 4 engineers started development of the

project. After implementation, this project was sent to in-house test

teams.

During the development, I designed very crucial module of this project of

generating thumbnails of each file type. Later on to improve page loading

performance I added Cache manager which keeps most recently loaded

Thumbnails. Cache manager, which keeps most recently loaded thumbnails, was

added later to improve page loading performance.

Thumbnail manager's job is to generate thumbnail by decoding the image/

first frame of video content. For all other static content it decodes one

file and uses it for all files of same kind.

Cache manager, keep three pages of thumbnails and keeps them into heap

memory. When user scrolls page, It makes sure that, images of thirty images

on top of the current image and thirty images below the current images are

already in heap memory.

This significantly improved performance of the page loading and reduced

thumbnail generation count for images which lead to improved application

performance in terms of less image decoding hence less usage of CPU cycles,

less battery consumption and and faster user experience.

Project 6: Widget Development Role: Senior

Software Engineer-1

3 * 4 Virtual Keypad

This was the next project after completing 1st phase of resource editor.

This project took me to the real telecom and mobile application development

domain. I was given the assignment of implementing a 3*4 virtual keypad for

the first touch screen phone by Samsung in Japan market.

In touch screen phones, as we don't have hardware keypad, virtual keypad

helps user in entering text, numbers, symbols, pictograms, face marks

(Emoticons) and Japanese and Korean characters.

This keypad was initially not a separate widget, but was a part of a Input

Editor widget. So initially it was designed and developed just as an

integral widget. Latter many application developers asked for such widget

for their requirement. Due to which this module changed to an individual

widgets.

QWERTY Keypad

After completing 3*4 phone keypad, I was given the responsibility to

develop QWERTY keypad. This project was an extension of the 3*4 phone

keypad. 3*4 phone keypad had 12 keys where as QWERTY keypad has 36 keys

including 26 keys for alphabets.

QWERTY keypad was written for the horizontal mode because horizontal mode

has sufficient space to display all keys and it will also help user to type

faster compare to normal3*4 keypad.

Japanese/English Input Method Editor (IME)

Input Method Editor was the widget used to enter character (text, number,

symbol, face mark (emoticon), pictogram and Japanese and Korean character.

Any application which needs user inputs is using this tool.

Input Method Editor is a collection of small widgets like a Keypad, an

editable widget (Edit area) and few other widgets. It is using APIs exposed

by the widgets which are members of it. This widget is exposing all the

necessary APIs which an application developer can use. To input telephone

number, this widget can be changed to state in which the keyboard has only

number and widget can input only numeric values.

This widget also supports text prediction for Japanese characters. English

prediction was unavailable, because English is not the primary language in

Japan.

Responsibilities:

Requirement collection from customer, analysis and high level requirement

analysis document.

Responsible for module design, inter-module communication, data flow, call

flow and API design.

Implementing APIs, user interface and application logic.

Performed system/unit testing

Fixing issues reported by customer.

Environment/Tools: C, QUALCOMM REX, Samsung Platform and Trace32.

Project 7: Resource Editor Role: Senior Software Engineer-

1

Resource editor was very prominent project. It was my first project in

Samsung. This project includes modules like

A standalone application with its unique IDE, an engine which generates

resource files,

An engine which parsers resource files and

A resource loader which takes the resource file as an input and generates

User Interface as per the resource file.

Here the term resource is generalized for a Window, bitmap, string, a

widget and anything which could be a resource for an application. A

resource is nothing but an external content which helps to enhance the

application in term of Look and feel, appearance, better readability and

visibility.

The GUI part of the project is a standalone application with its IDE. The

application and its IDE contains a visible toolbar, a drawing canvas

(area), a property window and a tree view window showing parent-child

relationship of all the resources.

Toolbar of the application has all the widget, supported by the framework

(platform), displayed in an iconic fashion which can be dragged and

dropped. Use can drag widgets and can drop them on the canvas area. The

canvas will draw dropped widgets and will place them to the point they

dropped. Use can change size and position of each dropped widget with just

a mouse click. User can manipulate properties of each dropped widget from

the property window.

Once user is done with GUI layout, and the widgets, use can generate

compile that GUI. Compilation of GUI internally generates a resource files

in a format understandable by the resource loader.

After compilation the resource generator will generate two files, one

header file, containing IDs of all resources and one binary file which

contain resource and its information. It's the resource file, which is

going to be read by the resource loader.

Now the job of resource loader is to read resource file, parse resource id

and its information and create user interface based on the resource files.

Responsibilities:

Requirement collection from customer, analysis and high level requirement

analysis document.

Designing system architecture, module design, designing inter module

communication, data flow, call flow and system states.

Designed User Interface workflow and state of each screen.

Developed system from scratch using C++ and MFC.

Performed system/unit testing.

Environment/Tools: C++, VC++, MFC, Trace32, QXDM, Samsung Proprietary

Platform Qualcomm REX, Windows XP.
