What I'm looking for

I’m open to relocating and looking to build practical systems, AI tooling, and data infrastructure where I can work on challenging technical problems and keep developing products end to end.

I’ve built backend and desktop features for Bookmap’s trading platform, working in a large production codebase and maintaining containerised build and test tooling.

At Huawei’s Warsaw Research Center, I designed and benchmarked data placement and migration algorithms for heterogeneous memory systems, profiling memory-bound code near the OS layer. At Huawei London Research Center, I built distributed Python pipelines and Elasticsearch retrieval infrastructure for an in-house AI agent.

I’m also building AI tooling for a competitive-programming learning platform, personal desktop tools, Python APIs, and automation scripts. As a two-time ICPC World Finalist, I teach algorithms, data structures, and Git workflows and coach an ICPC team.
