About Me
I work on databases, specifically query engines and the compilers behind them.
Query compilation
Built a backend for LingoDB that turns MLIR straight into x86_64 and arm64 machine code, without LLVM in the compile path.
Runtimes
Wrote a spec-compliant WebAssembly runtime in Rust, with both an AOT and a JIT backend.
Research
Published my work on fast bounds checking for 64-bit WebAssembly at VMIL 2024.
Education
MSc Computer Science at TUM, graded 1.0 with high distinction, with semesters at UIUC and NUS.
Experience
Software Engineer
CedarDB • January 2026 - Present • Full-time
- Extending the PostgreSQL compatibility of the query engine, stability and important bug fixes
- Improving storage layer performance on arm64
- Continuous benchmarking + improving telemetry
Student Researcher
TUM Chair for Database Systems • April 2025 - December 2025 • Working student, 20 h/week
- Worked on LingoDB, a compiler-based analytical database system built on MLIR
- Implemented a novel backend using TPDE, which translates MLIR directly to x86_64 and arm64 assembly, taking LLVM out of the compile path. It compiles 8 to 24 times faster than LLVM's -O0 pipeline at on-par run-time performance
- 19 merged pull requests, among them the TPDE execution backend, jump fusion, tuple support for the baseline backend, and faster load/store code generation
Software Developer in R&D
Rohde & Schwarz GmbH & Co. KG • February 2023 - March 2025 • Working student, 20 h/week
- Developed C++ libraries to enable high-speed communication between system components of signal analyzers
- Implemented diverse communication protocols, including TCP, HTTP, MQTT, ZMQ, and shared memory
- Created the first fully automatic C++ serialization framework through template metaprogramming
Tutor
TUM • April 2023 - March 2024
- Taught Operating Systems and System Software
- Taught Fundamentals of Algorithms and Data Structures
Working Student - Software Developer
CHECK24 Services GmbH • April 2021 - January 2023 • Working student, 12 h/week
- Developed browser-based internal tools with Python Django backends and JavaScript frontends
- Invented a scheduling tool that uses SAT solving to find optimal meeting slots
Software Developer for Internal Services
IfTA Systems GmbH • June 2020 - March 2021 • Working student, 10 h/week
Engineered a web-based time tracking system for HR, streamlining employee productivity management
