Oracle PL/SQL Developer

Hello, I'm Patrick.
I help companies turn business requirements into reliable Oracle PL/SQL and data warehouse solutions.

Remote · CET with US Eastern overlap

Oracle certified PL/SQL developer with 10+ years of experience, much of it building data warehouses in banking.

Services.

01

PL/SQL development

Translating business requirements into reliable PL/SQL packages, procedures, and functions while maintaining existing Oracle codebases with a focus on stability and maintainability.

02

Data warehouse development

Designing and developing Oracle-based data warehouses, including data models, staging processes, and the PL/SQL logic that loads and maintains them.

03

ETL & data integration

Building and tuning the data flows that move and reconcile data across systems, using PL/SQL or integrating with the ETL tools already used by your organization.

04

Making remote work, work

Hiring remotely takes trust, and I treat earning it as part of the job. I adapt to your team's way of working, whether that means Scrum, Kanban, or an approach that works best for you. I communicate clearly and make sure collaboration stays simple and effective.

My focus.

My career has taken me through data warehousing, data engineering, and everything around it. The work I keep coming back to is PL/SQL on Oracle, because it's what I enjoy most and do best.
