Experienced Data Engineer | MSc in Big Data | Real-time Pipelines, Cloud ETL, and Analytics Expert I build robust, scalable data pipelines — batch and streaming — that help businesses move fast and make smarter decisions. With deep hands-on experience in Apache Flink, Kafka, Spark, Airflow, NiFi, AWS, and PostgreSQL, I’ve helped teams design systems that are reliable, maintainable, and built for scale. My name is Tawfik, and I focus on delivering clean code, clear communication, and long-term solutions — not short-term hacks. ✔️ Improved data quality by 88% through an Airflow + Python ETL pipeline ✔️ Built real-time data streaming pipelines for financial systems using Flink, Kafka, and Elasticsearch ✔️ Delivered end-to-end AWS data lake architecture with S3, Redshift, Glue, Athena, and dashboards with QuickSight 🧑‍🏫 I’ve also mentored over 500 students as a Teaching Assistant in Big Data at Nile University in Egypt, helping many of them launch careers in data engineering. My academic background includes research in fine-grained event-time processing and watermarking in Apache Flink, which adds a unique edge to how I approach real-world streaming challenges. 👉 Take a look at my portfolio and client reviews — and if you’re ready to solve your next data problem, I’d love to talk.
