Juan Alberdi

• Development of batch processing solutions for international payments at CaixaBank, ensuring the automation, scalability, and reliability of critical processes.

• Responsible for reviewing and organizing developments (new and evolving), as well as preparing technical documentation, functional analyses, and hour/effort pricing for clients and internal use.

Technologies and Tools:

• Spring Batch: design and implementation of high-performance, large-volume batch processes, optimizing execution times and ensuring scalability and resilience.

• Oracle: optimization of SQL queries and advanced database management in mission-critical environments.

• Java + Spring Framework: development of modular and maintainable components, integrated into complex banking sector architectures.

Agile Methodologies (Scrum/Kanban): task management, sprint tracking, and collaboration in multidisciplinary teams using tools like Jira and Confluence.

Version Control (Git): use of repositories and branches to ensure code traceability and quality in collaborative environments.

Key Contributions:

• Implementation of batch solutions for massive international payment processes, reducing execution times and improving traceability.

• Optimization and continuous improvement of batch processes by applying good development and architecture practices.

• Preparation of hour and effort pricing to correctly size projects and facilitate planning with clients and internal teams.

• Active participation in requirements analysis and technical decision-making, consolidating my role as a programmer analyst.

• Preparation of key documentation (functional/technical analysis, development guides) for internal teams and clients.

• Collaboration in mentoring programmers and disseminating best practices within the team.

• Role Description:

◦ Participation in the development of batch solutions for banking sector projects, contributing to the automation and scalability of critical processes.

◦ Responsible for the implementation of batch processes, requirements analysis, and technical support, consolidating my role as a programmer-analyst.

• Technologies and Tools:

◦ Spring Batch / Java + Spring Framework: implementation of efficient and scalable batch processes in high-volume data environments.

◦ Oracle (SQL): regular use for data management in batch processes.

Linux: server management for script execution, task automation, process monitoring, and log review.

◦ Python: development of scripts for support tasks, data processing, and complementary automation to batch processes.

◦ Version Control (Git, SVN): code management and coordination with the development team.

◦ Agile Methodologies (Scrum): teamwork and project tracking through task boards and follow-up meetings.

• Key Contributions:

◦ Development of batch processes for large-volume banking operations, ensuring performance and reliability.

◦ Implementation of Linux and Python scripts to facilitate the automation of recurring tasks and process validation.

◦ Support in optimizing batch processes to improve their performance and robustness.

◦ Participation in planning and requirements analysis, providing technical proposals and design improvements.

◦ Active collaboration with the team in continuous improvement and development best practices.

• Technologies Used: Programming: Android. Frameworks: Spring Framework for efficient application development.

◦ Service Integration: Implementation of REST and SOAP services to facilitate interconnection between different system components.

◦ Database Management: Solid experience in handling MySQL to ensure data efficiency and security.

• Key Results: Contributed to project success by developing technological solutions that improved efficiency and user experience in the context of a smart city. This experience allowed me to consolidate skills in integral application development, from conception to implementation, covering both the server-side and mobile and web interfaces.
