• My team received company-wide distinction for reducing the deployment time of the entire stack from 6 hours to 1 hour, and fully automating the infrastructure provisioning and deployment processes.
• Created a custom Auto-scaling solution in AWS for the software that lead to millions of dollars in operations cost savings per year.
• Completely decommissioned the on-premises infrastructure supporting QRM within 1 year of the migration project initiation, leading to millions of dollars in infrastructure maintenance cost-reduction.

• Key member of the team that spearheaded the creation of Ford's Smart Mobility (FSM) Profile Management Platform (PMP).
• The platform is a set of cloud based micro-services developed with Java spring-boot that collects, exposes and manages user identity, user preferences and consent for a suite of applications used to transport people within a city using multiple mobility solutions like ride-share, taxis, trains, buses, bicycles etc.
• Deployed the MVP which included 4 micro-services in a Microsoft Azure cloud production environment within 6 weeks!
• Secured the communication with the deployed microservices behind an API-gateway using Spring Security and OAuth2 protocol
• This aggressive and successful feat was achieved by following extreme programing core practices like test driving development (TDD), pair programming, simple design and continuous integration/continuous delivery.

Provided technical leadership to the following IT initiatives:

• Continuous integration system migration which involved overseeing three cross-functional teams to provision and setup more than 100 virtual machines to drive cost reduction, provisioning automation, and improve end-to-end automated regression testing speed-up through cloud-based technologies.
• Perforce migration initiative into a new matured distributed version control system, GIT.
• Creating an effective continuous delivery pipeline to replace old software packaging systems built with ant and groovy with a new industry standard software compilation and packaging system based on maven.
• There were over 60 legacy groovy source files with an average of 500 lines of code in each source file that had to be understood, analyzed and re-written using chef to automate the continuous delivery pipeline.
• At the end of the automation, one click software releases without any human intervention was possible for all environments (production, pre-production, development, quality-assurance).
• Also, we created automation for overnight releases into the development environment using the newly re-engineered continuous delivery pipeline

Key Highlights:

• Drove and led significant efforts for Intuit's Electronic Filing Engine (EFE) enhancement, maintenance and support for more than two years, which serves more than 23 client applications including TurboTax, Lacerte, ProSeries, and QuickBooks, as well as over 90 million income and corporate tax returns yearly.
• EFE is an enterprise Java application originally built with EJBs; a key objective was modernizing and modularizing its architecture to use Spring 3 and hibernate; the purpose was to be container (JBOSS, Tomcat, Jetty etc.) agnostic.
• I was involved in this objective, and we completely re-engineered EFE to use Spring 3 and Hibernate in early 2016.
• The project took eight (8) months to complete.
• Successfully re-engineered the EFE's Groovy/Ant installer for EFE's migration into Amazon Web Services (AWS), which involved automation of the creation of a full production environment with over 70 dynamic and elastic internet protocol (IP) addresses, thus maximizing cutting-edge dev-ops technologies such as chef.
• Migration from legacy in-house cloud environment into an Industry standard cloud infrastructure (AWS) was a major, high visibility and fully funded project for Intuit in 2016; There are several product teams in a large organization like Intuit, and my team was one of the biggest, oldest and most important product teams because significant revenue and highly sensitive data flowed through EFE.
• The objective was to recreate new environments in AWS and forklift our software into those environments.
• After the migration was done, the software had to be fully functional and reliable for 90 million live customers.
• Several problems had to be solved to complete this migration; one of the key problems was re-engineering EFE's installer to work in a dynamically provisioned environment (no static machines), which I was responsible for.
• The original installer was designed using Groovy and Ant.
• The new installer would still leverage Groovy and Ant; however, it had to leverage chef as well.
• Any node in the environment's cluster could go down at anytime; hence the installer must be intelligent enough to automatically make a dynamically and newly provisioned node functional without ANY human intervention and with maximum reliability.
• I was able to meet those requirement and use the installer in AWS production within 4 months of development successfully.
• The migration was a major success that led to us winning an Award.
• Played an integral role in performing manual processes automation involving new development engineers and development environment establishment using docker, thus speeding the EFE onboarding process from one week to two hours.
• Played a significant role in encryption of data at rest and in-motion to successfully prevent UN-authorized access to EFE (Electronic Filing Engine), which stores the personal data of several tax filers in the U.S. and Canada: this was a key requirement for migration into the public cloud.
• A clear understanding of the security life cycle, vulnerability detection, and creation of countermeasures was necessary for the design and implementation of EFE's data encryption system.
• Created the QA (Quality Assurance) analysis framework/API using Node.js and AngularUI for helping QA engineers quickly aggregate metrics after regression testing.
• Attained various awards for displaying outstanding performance which included Win Together Award and Deliver Awesome Award in November 2014 as well as Forklift EFE into AWS Award in May 2017.
