Experience
Senior Software Engineer
Exadel Poland
- Developed core C++ features of Vectric CAD/CAM software for CNC routers, used by woodworking shops to make signs, cabinetry, furniture, and 3D carvings.
- Implemented and optimized 2D/2.5D toolpaths (profile, pocket, V-carve, drilling) with robust polygon offsetting, ramps, and holding tabs, cutting calculation time by 35% on complex designs.
- Hardened the geometry kernel against degenerate imported DXF, SVG, and PDF data (self-intersections, micro-segments), reducing customer-reported toolpath failures by 40%.
- Built G-code post-processors for 30+ CNC controllers (Mach3/Mach4, GRBL, Fanuc-style) and least-squares biarc fitting that converts polylines into G2/G3 arcs, shrinking G-code files by up to 60%.
- Accelerated the 3D material-removal simulation with CUDA kernels and a multithreaded CPU fallback, cutting preview time on large carving jobs from about 90 to under 10 seconds.
- Optimized OpenGL rendering of vectors and 3D toolpath previews (VBO batching, GLSL shaders, level-of-detail) for smooth navigation on projects with 1M+ segments.
- Built a Python regression harness that regenerates toolpaths and G-code for 500+ reference projects and diffs them against approved baselines in CI.
- Mentored 4 engineers, led code reviews, and worked with Vectric's UK product team on release planning and customer issue triage.
Software Engineer
AItkom Software
- Developed machine learning models in Python (scikit-learn, PyTorch) for telecommunication network modeling, forecasting cell-level traffic and KPIs for mobile network capacity planning.
- Built probabilistic traffic models (Poisson arrivals, Erlang B/C queueing) and validated them with goodness-of-fit tests and confidence intervals on 2+ years of hourly network data.
- Engineered features with pandas and NumPy and applied linear algebra (PCA, SVD) to compress 300+ correlated counters per cell, cutting training time by 70% without accuracy loss.
- Trained LSTM and temporal CNN forecasters in PyTorch on NVIDIA GPUs (CUDA), reducing forecast error (MAPE) by 25% versus a seasonal ARIMA baseline.
- Implemented KPI anomaly detection (Isolation Forest, seasonal decomposition), cutting false alarms by 50% versus static thresholds.
- Exported models to ONNX and served them with ONNX Runtime in a C# (.NET) service, scoring 10,000+ cells in under 2 seconds.
- Built an MQTT pipeline ingesting IoT test-device telemetry (NB-IoT, LTE-M) into InfluxDB to calibrate IoT/M2M traffic models.
Software Engineer
Prime Factor Studio
- Developed core C++ modules of a 2D CAD drafting application for construction drawings (floor plans, elevations, sections), including lines, arcs, polylines, splines, hatches, and dimensions.
- Implemented an OpenGL renderer (GLSL shaders, batched vertex buffers, view culling) that kept pan and zoom at 60 fps on drawings with 500,000+ entities.
- Wrote computational geometry routines (intersection, offset, trim/extend, fillet, polygon Booleans, hatch boundary detection) with tolerance handling for floating-point robustness.
- Built object snapping and selection on a quadtree spatial index, reducing hit-test latency on large drawings from about 200 ms to under 5 ms.
- Added DXF import/export for AutoCAD interoperability and scaled plotting (1:50, 1:100) to PDF and printers.
- Built the desktop UI in C# (WPF) over the C++ engine via C++/CLI interop, with layer manager, property panels, and undo/redo.
