Backend & Systems Engineer - Fintech and Trading Systems
Hi, I’m Kai, a backend-focused software engineer with a cybersecurity background, working on data-intensive and performance-aware systems in fintech and trading contexts.
My core experience is in Python and Go, building backend services, APIs, and infrastructure where correctness, scalability, and latency trade-offs matter. I enjoy working close to system boundaries; understanding how data flows, how failures happen, and how systems behave under real-world load.
I’m especially interested in trading systems, market data processing, and real-time software, and I’m gradually building toward quantitative development roles.
Based in the UK
