Project Description:SF2.0: Redesign the complete StoreFront E-Commerce application. transforming the monolithic application to microservice to cater a decoupled business components as services so the newly acquired tenants to be integrated and consumed. Proposed and present overall plan in moving the monolithic services to decouple microservices that are exposed by REST webservices. Co-team with the Solutions Architect to produce a technical specification and system integration requirement. Derived context bound modeling decomposing modules based on the business capabilities. Coordinating with stakeholders and Business Analyst in understanding the business context and designing the API around sub domain and business models. Presenting the best feasible architecture and recommending the overall decoupled microservice infrastructure and iterative and incremental enhancements. POC and introduced event streaming to capture the user interaction for analytical purposes, this was achieved by capturing events (messages) to Kafka and Casandra as DB and dashboard to visualize the data. Defined deployment model to provision infrastructure to deploy microservices in containers. Guiding the offshore to understand the application architect and adhere to industries coding standards and acceptable API design patterns. Decoupled UI, presentation layer and business layer to manage and deploy independently. Adapted Domain Driven Modeling to segregate commonly used domain models to business specific modules. Developed CI/CD pipelines for frontend and backend applications using GitHub actions, hosted runners, and Jenkins. Used on-demand sandbox Kubernetes environments for front-end development and validation. Used spring session with Redis for distributed session management. Increased the number of user sessions handled by the website significantly with this stateless architecture. Used SAGA and event sourcing approach to solve eventual consistency.

SF1.0: Migrating EJB based legacy StoreFront E-Commerce application to monolithic RESTful service application. Collaborate with stakeholders and internal development teams to define the approach to decouple the core business EJB components to REST API. Identified 400 EJB beans that have to be rewritten as a business decoupled service. POC to showcase the development and deployment methodology to have the decoupled bean as services in a week of time. Defined the strategy to move all the business components to services in iterative and incremental phases without the downtime of the application. Implemented strangler pattern to rewrite the services as a REST API. Designed multimale aggregate services that mimics the facade approach in EJB. Encapsulated the aggregated service with an isolated transaction to keep the data consistency. Recommending and documenting coherent technical proposals that meet the platform requirement. Performed detailed design reviews across different application modules and services owners. Ensure smooth development and incorporation of business architecture with other layers. Design and execute proofs-of-concept for critical enterprise modules. Coordinate with peer architects and business experts across the business unit to translate key strategic objectives into proposed and governable roadmaps and designs. Architecting and designing software solutions for various requirements that integrate with different lines of business in one enterprise. Building the core business framework and guiding team to implement the functionality around the core framework. Monitor the progress of the project, guiding the team on the technical implementation and reporting the progress and blockers to the stakeholders.

Worked with Financial institutions like : CITI Group, JP Morgan Chase and State Street.Collaborate with the product owner and development team to priorities the features to deliver in incremental releases. Recommended the Whiteboard drawing approach probably the most common and best technique used to share ideas. Implemented the best OOPS and design patterns across the application bringing the application close to pattern-oriented application. Monitor the progress of the project, guiding the team on the technical implementation and reporting the progress and blockers to the stakeholders. Implemented Agile methodology and best practices using Scrum, pair programming, feature card, TTD in one team room development environment. Effort estimation using quantifying story cards on point base. Coordinating with the co suppliers to understand and integrate the API they provide. Identified and fixed concurrent access, performance and memory issues. Developed various modules using Spring WEB and Core modules. Implement aspects for all cross-cutting concerns like security, logging and user interacting features. Consumed various data from different source systems like enterprise loan and customer data using web services, document from i-vault. Fax and Email from info-source services. Code refactoring, peer code review and compliance with the organization standards. Facilitate integration and configuration between Blaze-DS, Flex Spring and Java framework. Helped L3 team to understand the application and fix the issues.
