Hire the Best Apache Spark Engineers in Belgrade, RS
Belgrade, Serbia
Hi! I'm a Data Engineer based in Belgrade, currently pursuing a Master's in Information Engineering. Over the past 2 years, I've been building and maintaining cloud-based data pipelines, data models, and analytics workflows, mainly using Python, SQL, Spark, BigQuery, Databricks, and Infrastructure as Code with Terraform. What I can help you with: - Building and maintaining ETL/ELT pipelines using Python, SQL, and Spark - BigQuery + Dataform transformations, data modeling, and query optimization - Workflow orchestration with tools such as Dagster and Airflow-style patterns - Setting up and improving cloud infrastructure with Terraform - Working with AWS and GCP services for data ingestion, storage, and processing - Improving pipeline reliability, data quality, monitoring, and maintainability - Organizing raw data into clean, analytics-ready tables and models I've worked on projects involving e-commerce supplier data integration, cloud pipeline development, BigQuery model refactoring, event-driven AWS ingestion, and Spark/Delta Lake analytics platforms. I enjoy taking messy or unstructured data workflows and turning them into systems that are easier to understand, operate, and scale. If you tell me your goal - what data you have, where it should land, how often it should run, and what you want to analyze - I'll suggest a practical plan and we can start with a small first milestone.
