senior Java/Node.js backend HFT/Low latency
Comfortable with Node.js (docker/compose/bare metal) and can touch some DevOps if needed. Experience building parsers and "low latency" systems (~100ms scale) with Kafka, Redis, and other brokers. In Java, I prefer clean core Java (SpringBoot is fine, just slower for me). Worked on HFT with SPSC queues, NUMA affinity, byte-level optimizations, and Aeron as a broker. Also fine with hotpath optimizations, Big-O, and classic data structures.

Něco o mně
Mostly solo development, quite a bit of experience in node.js a bit less in java/kotlin. Have been working on large scale parsers, several automations (including resource protection bypasses), now building own HFT system, the goal is to create quant playground for myself.
