Present Role Senior Architect and Development Manager in Lexmark International, Kolkata

2. EXPERIENCE SUMMARY
I have been working with Lexmark International India Private Limited for 10 years. Earlier, I worked with
Tata Consultancy Services for 5 years. I have the experience of successfully delivering quality software to
our customers in a variety of projects of different sizes and complexities on various platforms. Being one of
the first members of Lexmark Enterprise Software’s Kolkata chapter, I have the experience of building an
organization from ground up. Throughout my career, I have assumed various technical leadership roles –
that of a Module Lead, Team Lead, Domain Owner, Architect and Senior Architect. For the past 3 years, I
am also handling the responsibility of people management for the employees in my teams.
JOB OBJECTIVE
I see myself as a problem solver. My primary objective has been to provide the optimal solution to the
problem at hand that will delight our customers as well as serve the business interest of my organization.
For that, I aspire to assume leadership roles in the organization wherein I am empowered to influence
decisions and implement them in a way that would help my team, department and the organization grow.
PRESENT ROLE
In my current role as a Senior Architect and Development Manager, I provide technical direction to my
teams and manage the entire SDLC, besides coaching and managing the performance of my direct reports.
I interact with the customers and the product management team regularly to gather requirements, analyze
them, propose reusable solutions and decide the delivery timeline. I like to keep myself abreast with the
latest trends in hybrid app development (web & mobile), javascript frameworks, dev-ops, architectural
patterns etc.
I always encourage my teams to be self-managing. Also, my role as a senior architect needs me to provide
technical guidance for some of the more demanding requirements. Often times, I implement POCs for some
of the more complex technical needs. I encourage my teams to take calculated risks, question status quo
and adopt industry best practices for developing solutions in Agile with particular emphasis on automated
testing, continuous re-factoring and shorter release cycles. My teams thrive on adapting to changes be it in
terms of requirements, technology or otherwise.
My high performance teams are primarily responsible for providing solutions to manage unstructured
content of our customers. These solutions facilitate easy content-capture & content organization that
ultimately feeds the content to the customized workflow demanded by the business processes adopted by
our customers. To achieve the same, they have been working on the following: -
 Integration: Integrate Lexmark’s ECM product Perceptive Content with various ERPs like
Salesforce, SAP, Microsoft Dynamics AX, Kofax Total Agility (in-house BPM product).
 Financial Process Automation: Ease customer’s Accounts Payable workflow from end-to-end
right from Invoice capture, Invoice data extraction, Invoice processing and approval.
 Higher Education (Admission): Streamline Admission workflow beginning with capturing Student
and Application info and then managing the approval workflow.
 To achieve such deep integration with 3rd party ERPs, my teams use Lexmark’s Integration
Framework called Perceptive Connect Runtime which is a OSGI based middleware that facilitates
easy hand-shaking between variety of 3rd part systems.
 Until very recently and for over 2 years, I was managing teams who were developing re-usable
libraries to address different aspects of managing content. Some of the key libraries delivered are
Capture, Document, Workflow, Search, Viewer and Print. All these libraries are built using
Lexmark’s own Application Development Framework which ensures that the libraries are platform
independent, backend-agnostic, form-factor aware, HTML5 based, responsive client-side modules.
Besides managing project execution, I dedicate time towards building my teams. This requires, among
other things, having regular one-on-ones with my employees to understand their aspirations, identify
leaders, set expectations between each other, seek and provide feedback and most importantly help them
perform at an optimal level leading to their overall career growth. I am also closely involved with recruitment.

3. From time-to-time, I like to take up new initiatives like organizing online coding competition at Lexmark
Kolkata. I practice and promote knowledge sharing sessions with the aim of removing information silos. I
have tried to provide my employees with a platform to innovate and possibly apply them to their current
projects. The results have been quite satisfactory.

18. Designing software models to simulate Body Control Electronics of an Automobile (TCS)
Duration May 2005 to Dec 2005
Description
A modern day vehicle needs to carry out several intelligent functionalities such as
Adaptive Cruise Control, Immobilizer and Anti-Theft Alarm. These functionalities
are shared among electronic components called Electronic Control Units or
ECUs. Several ECUs are installed inside a vehicle and are interconnected to
each other through a network called the Control Area Network (CAN). The main
aim of the project was to design and develop software models that will simulate
these functionalities. Models were developed using State Charts and Activity
Charts. The tool used for developing the models was Statemate. Simulating a
particular functionality of an automobile using Statemate models allowed a better
understanding of the requirements. This considerably minimized the chances of
errors while developing the actual hardware using ECUs.
Role Team Member and Function Lead
Contribution
Served as a function lead for two critical and complex functionalities of an
automobile namely, Immobilizer and Diagnosis. Developed models and test
benches to simulate and test these functions. Was also responsible for
developing, simulating and testing CAN communication model for a given vehicle.

19. Behavioral Modelling Frameworks tool (TCS)
Duration Sep 2001 to Jan 2003
Description
The aim of the project was to develop a tool called Behavioral Modelling
Frameworks (BMF) that would try to formalize the ‘requirements capturing’ stage
of SDLC. This was achieved by capturing the requirements using mathematical
models rather than adopting the conventional way of documenting the
requirements in English language. In this manner, precise and unambiguous
requirements could be gathered from the client. Message Sequence Charts
(MSCs) and High Level MSCs (HMSCs) were the main constructs of this model.
MSCs are similar to sequence diagrams of UML. However, MSCs have strong
mathematical foundation and hence they can be formally analyzed. HMSCs, on
the other hand, are directed graphs where each node points to a MSC or another
HMSC.
Role Team Member
Contribution
Developed models using MSCs and HMSCs that tried to capture the
requirements described in a given problem statement. Implemented algorithms to
analyze the models and generate all possible use case scenarios and then
filtering out the practical and meaningful scenarios. Models were also analyzed to
find out the race and deadlock situations.
