• Owned several production database and service migrations in Seznam’s identity backend.
• Designed password storage that met new requirements and kept old passwords valid.
• Helping move deployments to Argo CD GitOps, C++ builds to CMake, and dependencies from Debian packages to Conan.
• Identifying hidden risks and assumptions in modernization proposals, and the cost of mitigating them, so the team can decide which to accept.

• Joined a new three-person team reviving an acquired ~10M-line broadcast weather suite, starting by restoring its build environment.
• Reconciled divergent customer-specific branches across five Git repositories, speeding development and helping ship customer-facing improvements alongside maintenance.
• Grew into the technical lead role, participated in hiring two engineers and an intern, and mentored teammates to lead increasingly complex projects.
• Proposed process experiments through which the team replaced fixed two-week sprints with a lightweight Kanban-style flow it found more efficient.

• Developed and optimized robust 3D mesh Booleans and spatial queries in BlueSkyPlan dental planning.
• Moved heavy computation off the UI thread, substantially improving responsiveness.
• Introduced modern CMake and pioneered Conan so computation ran standalone on Linux for integration with a cloud platform.

Designed and implemented a 4D-DCT light-field compression method in C++, building on the bachelor’s thesis, and coauthored two comparative papers.

Thesis with TESCAN 3DIM: CPU visualization of large volumetric data (cache-aware data structures, parallelization, vectorization).

Thesis Lossy Light Field Compression: Dean’s Award and Excel@FIT 2019 recognition.
