Beschreibung

Senior Backend Engineer specializing in distributed systems, functional programming, and high-throughput data pipelines.

I bring 10+ years of experience building scalable backend services for companies like SoundCloud, Zalando, and Barclays. My expertise includes:

- Scala (Typelevel stack: cats, cats-effect, fs2, http4s, akka-stack)

- Distributed systems architecture & microservices

- Data engineering (Kafka, Spark, Databricks, BigQuery)

- Python for data analysis and backend services

- Cloud infrastructure (AWS, GCP, Kubernetes, Terraform)

I specialize in building resilient, maintainable systems using functional programming principles. Whether you need to scale existing infrastructure, migrate complex data pipelines, or architect new distributed services, I deliver production-ready solutions.

Available immediately for remote contracts across the EU.

F Technical Co-design: Collaborated with engineers and business Nostr experts to for mat the business idea and test the technical decisions that form the foundation of the platform against Nostr system. F System Architecture: Architected a distributed automated traffic intelligence system on the Nostr protocol, designing a resilient Scala-based infrastructure to handle de centralized data streams. F High-Throughput Ingestion: Engineered a non-blocking pipeline using Scala and fs2 that synchronizes and deduplicates 1M+ events across a 50-day sliding window with less than 6 minute BigQuery latency. F Behavioral Analytics: Leveraged Python (Polars) for time-series analysis and fea ture engineering; identified automated and spamming traffic patterns to bootstrap the platform's initial detection dataset. F Network Integration: Actively developing a high-performance Rust client for private relay communication, enabling publishing real-time spam scores in a private relay inside the network.
