Software Engineer Manager
Resume:
Hello,
I am a PhD in Software Engineering with special focus on software maintenance and automation of business processes. In various projects and roles that span the software lifecycle development, I have moved from development to quality assurance to build-release-deployment cycle management and most recently, bare-machine environment setup on a cloud in a DevOps role.
My roles have consistently been that of a lead software engineer and responsibilities have included interacting with cross-functional teams, reporting into CTO, CEO or Head of Infrastructure management. As a lead I am able to craft organizations, processes and management of software systems that align with business requirements. Experience has also enabled me to set and manage business expectations to match technical and technology capabilities as well as deal with personnel management and issues.
DevOps is currently an exciting area as it brings about change in operations, making continuous integration and continuous deployment a higher priority and goal than ITILs structured and silos-based smooth operations focus. Agile DevOps is about having flexible processes in place that enable fast turnaround time especially in testing or deploying changes. Challenges in this area often have to do with non-Agile teams attempting to reach goals that are not in their reach and the solution to this is to make teams agile through small iterations that are unique to the team; i.e. the exercises and iterations the team requires to go through need to be identified and then executed till the team is Agile – and is able to evaluate itself as being Agile. Being able to prioritize and identify issues is just as important as being able to solve the issue.
In my most recent projects, I have undertaken the role of an end-to-end Solutions Engineer and in this capacity I am able to ensure different teams and solutions play well together and integrate in context of each other and not in isolation. To this end, I employ my own software engineering method, a post-agile matrixed approach that I call Tactile. Tactile maps a project’s requirements to verifiable tests and milestones for both tracking purposes and to ensure alignment of solution to expectations at each milestone (which is also a checkpost).
I have employed Tactile most recently to configuring a bare-machine on a cloud using Chef, a ruby-based framework. I have also researched Ruby as a scripting and web application language and Rails as a REST framework for web applications. This research was done to assess software maintenance needs of the Web Application stack that uses Ruby on Rails and SQL-based database.
With Best Regards,
Chandra Gupta

The system includes a staging directory for the intermediate transformations and manual steps to convert the data into pdf format and excel format before sending it via email to recipients
Used Ubuntu Linux 13.04 using /bin/sh scripts, Ruby 2.0, REST API & MySQL 5.5
3.Effect of Duck Typing, Closure and Scope resolution on maintenance of Ruby on RAILS Applications
Identify Ruby language constructs that make program understanding and debugging difficult, such as the yield co-routine, scope resolution of class variables, duck tying, metaprogramming and the mix of syntax features from different programming languages
Identify and solve RAILs maintenance issues such as relying on programming conventions to ensure model-view-controller design pattern structure, connection between data model and app using plurals, routes.db matches based on regular expression matching. Also analyze the pros and cons of the DRY – “Don’t Repeat Yourself” principle and “Convention over Configuration” principle from a maintenance perspective and code change perspective.
Compare and contrast Ruby with other Object-Oriented and Scripting languages to improve Ruby scripts

Designed an automated process to make each test independent of other tests.
Worked with TruView Risk Management Team to improved their release and installation process.
September 2009 – November 2009
Bloomberg, NY Senior Software Engineer
Fixed a production issue by tracing back code changes in code repository, manually reviewing logic and detecting defective logic. Extracted the design of a complex reporting process on the Analytical Desk (ADSK) ticket processing system to extend the system with a new ticket picking algorithm.
Worked on a reporting service that connected to a SQL Server Database and proprietary Fortran coded database to extract statistical data, calculate ranks for representative performance, convert the data to XML and provide it to GTK screens. Quickly learnt the Bloomberg Application Server (BAS) Services and Rapid/GTK
