About

With over a decade of experience in Oracle APEX and PL/SQL development, I have honed my skills in building and maintaining high-quality applications, particularly in industries such as telecommunications, energy, logistics, and finance. My journey began at TBD Systemy Informatyczne, where I developed and optimized financial-accounting and contract management systems, significantly improving user experience and system performance. I have also played a key role in implementing CI/CD processes to control application deployment and database schema changes, ensuring seamless operations and adherence to Service Level Agreements (SLAs). My expertise in database management, coupled with my experience in training and client consultation, has allowed me to deliver software solutions that simplify and enhance the work of government officials and other end-users. Currently, as a Senior Oracle APEX & PL/SQL Developer and Maintenance Team Leader at Pretius Low-code, I lead a team responsible for maintaining and enhancing client systems across multiple sectors. My role involves analyzing requirements, conducting client meetings, and implementing CI/CD processes to ensure efficient application deployment. I am dedicated to providing top-notch support to clients, swiftly addressing reported issues and ensuring the smooth functioning of production systems. My experience also includes roles in quality assurance and testing, where I contributed to major projects such as Smart Dom and Cyfrowy Polsat Go, validating financial data and ensuring compliance with international standards. My career is marked by a commitment to continuous improvement, technical excellence, and delivering solutions that meet and exceed client expectations.
