I’m a software engineer in low-latency trading at Digital Wave Finance AG in Zug, Switzerland, where I build exchange connectivity: market data and private streams for venues such as Binance. What pulls me in is the part of the stack where microseconds matter - low-latency and high-frequency trading systems, and the hardware underneath them.
I graduated from EPFL with an MSc in Computer Science, specializing in Systems, after a BSc at the National and Kapodistrian University of Athens.
Research
Before industry, research took up a large part of my time. For three years at the Athena Research Center I built a query optimizer for SQL queries with user-defined functions, using tracing JIT compilation and operator fusion - up to 27× faster than Spark, SQLite and PostgreSQL. That work led to QFusor (ICDE 2024, Best Demo Paper) and a full paper at EDBT 2026. At EPFL’s DIAS lab I worked on GPU-accelerated query processing over out-of-memory data (DaMon 2025) and on predicting execution time for JIT-compiled database engines (CIDR 2023).
In 2025 I interned on Oracle’s MySQL HeatWave team in Zürich, on caching and concurrency control.
Interests
- High-frequency trading and low-latency systems
- Memory ordering, lock-free programming, allocators
- Database internals and query optimization
- What the hardware actually does - caches, TLBs, the memory system
