Senior member of the engineering team responsible for the development, maintenance, and continuous evolution of large-scale, mission-critical enterprise systems for public-sector clients.
Extensive hands-on experience working with legacy Delphi codebases using Delphi 5 and Delphi Tokyo, focusing on writing clean, testable, and maintainable code while ensuring system stability, scalability, and long-term sustainability.
Regularly performed deep performance tuning, debugging, and troubleshooting across multiple environments, with strong attention to system-wide impact analysis and optimization.
Played a key role in a major architectural overhaul of the business unit’s core product, isolating more than 70 tightly coupled libraries into independent repositories, eliminating circular dependencies, and migrating from Jenkins to GitLab CI/CD. This initiative reduced CI pipeline execution time from 50 to 15 minutes, improved IDE startup performance from over 60 seconds to under 10 seconds, and resulted in a scalable architectural model adopted across multiple engineering teams.
Strong focus on software quality and reliability, consistently designing code with testability in mind and implementing automated unit tests using DUnitX to validate business rules and critical components.
Actively contributed to modernization initiatives through the development of .NET APIs to expose and decouple legacy functionality, including asynchronous integrations using RabbitMQ, enabling gradual system evolution and integration with newer services.
Worked with relational databases including SQL Server, Oracle, DB2, and PostgreSQL, designing and optimizing queries, data access layers, and transactional workflows.
Collaborated closely with other engineers in architectural discussions, supported peers through code reviews and technical guidance, and applied AI-assisted tools throughout the development workflow to enhance productivity, troubleshooting, and solution design.
