As a Software Developer/Enterprise Java Developer at Aimsio, I faced the challenges of designing and developing different parts of our software as a service using technologies based on Java, Vaadin framework, SQL database, message broker, and Hibernate. As a member of Aimsio's platform team, my responsibilities included:Designing the architecture and Developing a Budgeting module to synchronize Budget items with Change Orders and all the systemwide constraints, enhancing the budgeting process, resource management, and data consistency.Implementing a dynamic form builder module that can provide different sets of functions and views to the end-user based on their access level and role, enabling them to define forms and generate reports based on their data and workflows.Developing a Native Spreadsheet Vaadin component with the ability to apply complex logic across rows and columnsImplementing a Condition System integrated with the user's session, role, and active tier controls the accessibility of report actions.Introducing a testing strategy roadmap for the development team to fix the flaky tests, manage the migration of unit tests and integration workflows, and update legacy JUnit 4 tests to JUnit 5 to improve the tests and code quality and enhance the CI/CD process.Participating in the general system architectural design process, collaborating consistently with other team members to develop and improve the various backend and web services modules.Identify the project's vulnerabilities and propose a roadmap to upgrade and migrate system modules to the latest LTS versions without interrupting the business side. Manage the system modernization initiative.

Worked as a Data Scientist and Research Assistant on Open Entity Resolution and Entity clustering using Deep Neural network approaches. During my collaboration, I used large language models (LLM) and NLP techniques developing software to study their practicality on Entity Matching under the supervision of Dr. Davood Rafiei.Teaching Assistant in File and Database Management (CMPUT 291) course under the Supervision of Dr. Rafiei. In this course, we helped students with basic concepts in computer data organization and information processing, entity-relationship model; relational model; SQL and other relational query languages; and storage architecture. They learned how to use Python, SQLite, and MongoDB.Teaching Assistant in Information Retrieval Course under the instruction of Dr. Denilson Barbosa.

At Fanap Co., I was a part of the SAKKU Container Orchestration Platform and POD Space Cloud Storage teams. These experiences allowed me to work closely with my colleagues to address complex technical challenges including:SAKKU Container Orchestration Platform- Worked as a software engineer leading a diverse engineering team with 9 software developers and 2 DevOps engineers.- Designed the project's architecture, implementing microservices software using Spring Framework and MVC architecture.- Hands-on involvement in backend development, fixing bugs, adding new features, and improving performance.- Planned the project's technical roadmap, guiding its evolution in line with our strategic objectives.- Leveraged cutting-edge technologies including but not limited to Apache Marathon, Mesos, Docker Swarm, etc in the development process, resulting in a remarkable 70% reduction in resources.Open-sourced many developed tools, services, and Docker images to support the open-source community. POD Space Cloud Storage - In the POD Space Cloud Storage project, I had the opportunity to contribute as part of a great team, solve complex problems, and collaborate to address various technical challenges. As a software engineer, I played an integral role in enhancing the cloud storage module, refactoring it using Spring Boot, and implementing an efficient file-sharing schema that resulted in a 40% improvement in performance.- Created a scalable service to generate thumbnails for the uploaded files.- Our team successfully migrated the project from Java EE to the Spring framework, standardizing the REST APIs and optimizing the response time performance.- My involvement extended to designing and developing a robust file-sharing system, implementing APIs for seamless file-sharing, and defining access levels for files and folders.

Tapleader SDK was an in-app real-time crash reporting platform that helps mobile applications prioritize and troubleshoot their most prevalent crashes based on the impact on real users. I implemented the Android library with Java and Android SDK to collect clients' activity data in different environments.SignalGo is a framework to distribute a computation among a group of mobile clients. My task was to design the client-server architecture of the framework and implement the Java client using Java 8.
