Available to hire
I am Penelope Jones, a Developer/DevOps engineer with broad experience in middleware, Oracle databases, ETL, and large-scale finance and telecoms projects across multinational teams. I have worked on migrations, CI/CD automation, and agile delivery for clients in banking, government, and utilities, with a strong focus on performance and reliability. I thrive on solving complex data and integration challenges and enjoy collaborating with stakeholders to design robust, scalable solutions.
In addition to hands-on coding in C/C++, Java, Python, and PL/SQL, I have deep experience with Oracle technologies, Linux/Unix environments, and DevOps tooling. I am comfortable across database design to middleware, CI/CD, and production support, and I bring a pragmatic, user-focused approach to delivering high-quality software and data products.
