- Implemented new Java, Spring, and PostgreSQL testing standards that leveraged software quality.
- Refactored and improved various legacy components in a time-sensitive environment.
Senior Java Expert
- Maintained and improved a deployment microservices pipeline to AWS ECS using Docker and CircleCI.
- Developed various fixes and improvements on Spring Boot microservices that integrated with Firebase, MySQL databases, AWS SQS, and AWS S3.
- Worked on a very tight release schedule and ensured that deadlines were respected.
MP Analytics Limited
- Maintained and improved an application that gathers data from multiple banks and creates analysis of investment strategies.
- Improved call times on various code parts by optimizing SQL queries and JPA implementations.
- Implemented new requirements along with a new test structure.
- Split up the project into microservices and created new Github actions deployment jobs, Dockerfiles, and server setup scripts.
- Created an asynchronous file processor to speed up XLS file uploads that run in the background with Amazon SQS and S3.

Java and Spring Engineer
- Developed Java AWS Lambda functions for processing IoT messages from personal safety devices. Configured AWS IoT rules and Kinesis Stream to interact with the Lambda function.
- Created a Java critical section locking mechanism to handle parallel processing of device messages and avoid concurrent changes on devices.
- Improved the legacy codebase with constant refactoring, reorganization of dependencies, and introduction of unit tests, integration tests, and end-to-end tests. That heavily increased delivery reliability and sped up the deployment cycle.
- Improved the overall development processes with better PR reviews and helped propose a better scrum process by keeping it lean.
- Implemented a solution to avoid duplicate message processing using Memcached on AWS Elasticache.
- Created an end-to-end tester platform to allow testing messages flow from AWS IoT to Kinesis, Lambdas, Java API, and DB.
- Developed a continuous delivery strategy for zero downtime on production deployments allowing a rollback when necessary.
- Created an AWS Lambda function for processing and storing the device's audio data on S3.
- Redesigned DB integration test architecture, enabling tests to run up to five times faster and with 1/3 code lines.
- Implemented an AWS X-Ray tracing service for an API, instrumenting AWS Lambda and external services calls.
- Developed an MVP application using Spring Boot to send out forms to clients, process their responses, and provide a dashboard for analyzing the responses.
- Structured a microservices architecture using Netflix Eureka.
- Created a deployment pipeline using Github and Heroku.
- Developed REST API integrations with Typeform and Cumul.io.
- Defined project structure with Spring Boot 2 and developed most of the application.
- Led two other developers ensuring code quality and testability through code reviews.
- Created an integration layer for interacting with ERP and CRM sides using Spring 5's new web client.
- Created test cases structure for each code sector: controllers, database, and entities. Achieved 75%+ overall code coverage.
- Created definitions of how to integrate with external services from logistics providers, matching our modeling to providers' custom modeling.
- Developed integrations with logistics carriers using an API made by P44 for data parsing/processing.
- Developed unit and integration tests for components using the latest standards.
Java Lead Engineer
- Architected a complete Java 8 with Spring Boot project.
- Created REST web services for survey processing, reports, benchmark, and client configurations.
- Developed full project test coverage with multiple scenarios.
- Created an email processing and queuing system for sending out surveys.

- Created the continuous integration and deployment pipeline with Docker and CircleCI.
Back-end and Web Developer
- Architected an AngularJS web front-end application using Grunt.
- Structured the deployment pipeline using CircleCI and Cloud66.
- Developed a standalone Java application that runs on clients to extract DB information from legacy Sybase and communicate to an FTP server.
- Created a Spring Batch data integrator that imports data from various clients into a multi-retailer DB.
- Developed a web application using AngularJS and Bootstrap 3 for creating multiple crops of a single picture.
- Managed Ubuntu Linux servers and Wildfly application server.
- Created REST integration with Imagga.com and Imgix APIs to post-process images.
