Projekthistorie
- Architected and implemented a production-grade Intelligent Copy-Trading & Vault Aggregation Platform on Hyperliquid DEX — a microservice-based event-driven system targeting sub-500ms p99 end-to-end copy-trade latency (leader fill to follower order submission), 10,000 copy-trade events per second, 99.95% platform availability, and up to 10,000 concurrent followers per leader
Stack: Java 21, Spring Boot 4.0, Apache Kafka, Kafka Streams, Spring Cloud Gateway, Resilience4j, LMAX
Disruptor, Redis, PostgreSQL + TimescaleDB, Web3j (EIP-712), Apache Avro + Confluent Schema Registry,
Prometheus, Grafana, Testcontainers
- Architected and implemented a production-grade microsecond-level tick-to-trade HFT engine in Java 25 targeting on-chain prediction market CLOBs. System architecture prioritizes deterministic latency over throughput, with zero heap allocation, zero virtual dispatch, and zero CAS operations on the critical path
Stack: Java 25, LMAX Disruptor, Netty/Epoll, Agrona, Chronicle Queue, Web3j, Websocket, REST, JNI/C (RDTSC), ZGC, VarHandle, MemorySegment (FFM API), ByteBuddy, HdrHistogram, JMH, async-profiler, Linux perf
Architected and delivered mission-critical, event-driven microservices for a B2B corporate payment platform serving 55,000+ enterprise clients across 57 countries, enabling real-time virtual card provisioning that reduced card issuance from days to under 30 seconds.
Stack: Java 8, async-profiler, Spring Boot, Spring Kafka, Apache Kafka, Hadoop, Azure, Kubernetes, Docker, Helm, Jenkins, Git
Architected and delivered mission-critical components of the RI-Platform (Traveler information system), a
centralized real-time data platform serving millions of daily passengers across thousands of trains, processing hunderds of millions of events daily with 99.9% availability.
Stack: Java 8, Multithreading, Low latency, GC tuning, Python, Spring Boot, Apache Kafka, Kafka Streams,
Apache NiFi, Hadoop/HDFS, MongoDB, Docker, Kubernetes, AWS, Elastic Stack, Prometheus, Grafana, Jenkins
