Product at 90% completion. Product release waiting for branding. Senior Java Software Developer MotionPoint Corporation, Coconut Creek FL Nov 2015- Nov 2019

● Web based Computer Aided Translation Tool:

A web-based management and translation tool that allows customizing and managing the content translation flow and features a full-fledged translation tool for linguists.

Application transition to microservices architecture driven by scalability and maintainability concerns

■ Participated in formulation of strategy for transition, which included:

● Domain decomposition.

● Refactoring and modularization of the monolith to allow for easier extraction of functionality

■ Implementation of an API Gateway using Spring API Gateway for REST-API components using service self registration and client discovery with Eureka and Ribbon.

■ Migrating configuration to Spring Cloud Configuration Server.

■ Modeled distributed interactions using the Saga choreography pattern.

Legacy implementation

■ Maintained a J2EE web application built completely on JSPs, servlets and in-house ORM for data access on SQL Server.

■ Detected and fixed multiple performance bottlenecks related to excessive synchronization as well as identified opportunities for parallelization of tasks that manifested in increased customer satisfaction.

■ Increased unit coverage from 3% to 66% with JUnit, Mockito and PowerMock to stabilize application.

■ Mavenized the application and built integration tests with JUnit and H2 Database and automated user acceptance tests with Selenium as part of build automation .

■ Transitioned the in-house ORM and connection pooling to Hibernate and servlet container-managed connection pooling.

■ Implemented automatic detection of database schema version and flexible mapping with Hibernate, allowing for backwards compatibility and schema validation at application startup.

■ Introduced VeraCode static analysis reports as an effort to integrate security into our CI pipeline. Fixed security vulnerabilities associated with the application itself and its dependencies.

■ Migrated read-only, historical data for reporting/audit to a separate database, increasing performance significantly.

● Translation Service (T-Server)

A mission-critical proxy technology used to dynamically generate and serve multilingual content in real-time from the client’s original websites, featuring real-time content detection and content scheduling.

Microservices implementation and migration

■ Microservices implementation using Spring Cloud and Netflix stack.

● REST API Gateway with Zuul.

● Client-side discovery services with .Eureka and Ribbon.

● Spring Cloud Security/OAuth2 and JWT.

● Distributed logging and tracing using ELK and Sleuth.

■ Data migration from SQL Server to AWS DynamoDB via AWS DMS

■ Loaded data to AWS Elasticsearch with DynamoDB Streams and Lambda to allow for full text searches, spelling reviews by translation supervisors, translation versioning and history searches.

■ Implemented distributed read-through cache (Redis) and application cache (Memcached) to allow for better performance and collaboration between application components.

Legacy implementation

■ Responsible for finding and fixing synchronization issues affecting software performance and correctness, as well as proactively identifying opportunities for caching, parallelization and concurrency bottlenecks

■ Implemented a cached approach that allows the proxy to function and eventually recover from a DB outage

■ Migrated from an HTTP-based communication for low-priority, background requests to a message driven paradigm using RabbitMQ

● Translation data feeds

Custom translation data-feed for multilingual retail clients [10 languages], as an extra entry point for clients to access the Translation Service (T-Server) in order to translate new content under different contract rules.

Established mechanism for clients to submit files in multiple formats via SFTP with content pending for translation and return the translated files keeping file version control for contract purposes. J2EE/quartz/T-Server.

● MotionPoint Global Sitemap

A GSM allows users from around the world to view search results content translated into their local languages.

■ The MotionPoint Global Sitemap automatically replaces a client’s sitemap with translated URLs. by applying google rules/suggestions as XML’s attributes to serve the correct language or regional URLs in search results.

■ This process can be run on-demand or automatically scheduled for certain intervals to refresh the GSM with new and/or modified URLs. JBoss/ Java/ Quartz/ Svn/ T-Server.
