Robert Nasarek
Data Engineer & Developer
Hi I’m a freelance backend and data engineer specialising in data modelling, ETL pipelines, and data-centric application architecture. I design and implement scalable APIs and backend systems using Python and modern web frameworks like Next.js, Drupal, and Django to build robust data workflows for analytics and machine learning use cases.
My focus is on semantic and structured data systems that turn heterogeneous sources into reliable, queryable, and reusable knowledge. I deliver production-ready solutions, including containerised deployments and reproducible data pipelines, with an emphasis on correctness, performance, and maintainability.
