PROFESSIONAL EXPERIENCE

Confidential

Technical Lead

Responsibilities:

• Following end-to-end process of Application software development using Agile methodology and Test-driven development (TDD).
• Analyzing the business requirements and propose an appropriate functional and technical solution.
• Interact with Onsite coordinator and Clients on a daily basis to understand the user stories created in Jazz RTC, Voting the story points and deliver the same at the end of the day or at the end of committed story points.
• Involve in various phases of Software Development Lifecycle like Design, Development and Testing of tasks for corresponding Sprint.
• Build core foundation libraries for Citi E-commerce applications, Digital wallet applications and cashback reward program to ease their implementation and maintenance as an automated process at each step
• Followed Microservices architecture/patterns to achieve Faster/Independent deployments of other services, Reduced Complexity, Increased Performance, easily debug gable/readable to any developer and make applications start & Communicate faster while interacting with Client/UI.
• Develop multiple API’s like MongoDB Connectivity API, SHA2 Algorithm API, Spring Cloud Configuration Server API by using Microservices architecture and authenticating the same via Platform Security Gateway
• Develop Swagger UI for each and every software library by importing Swagger API as dependency and write a Spring Configuration file to enable Swagger2 by including the Controller files package and path to build Swagger api docs
• By implementing Swagger UI, it is very easy for any user or developer to unit test all the REST End points and know the request parameters names which will make hassle free for developer to frame URI Path and test it via Poster/REST Client etc.
• Work with E-commerce application teams for a sprint or two and integrate the developed API’s with their applications and resolve all the issues wile integrating. By this, we can achieve automated solutions at each step of application development like Connecting to Database like MongoDB, Encryption and Decryption using SHA2 algorithms for security, Configuring Spring cloud configuration server for Zero-down time in production for small environment variable updates & Auto scaling
• Using Jenkins Server to deploy all the developed to Pivotal Cloud Foundry (PCF)
• Have configured JUnit setup for the application to achieve Industrial standard unit testing with multiple test cases at each component level.
• Have configured AppDynamics to monitor the applications health in Production once deployed like Severity 1 issues, Down time in production, Memory Leakage etc.
