About me
I offer practical one-to-one Python lessons for beginners. We work through short examples, write and change code together, and practise understanding errors. My lessons use structured slides, guided exercises and simple programs covering variables, input and output, calculations and conditions. You receive example code, a short recap and practice tasks. Message me with your current level and learning goal so we can plan a focused first lesson.... Read more

Logitech

Engineering Intern

Logitech • Full-time

Aug 2025 - Aug 2026 • 1 yr

Designed and released an open-source Logitech Options+ plugin that connects Logitech peripherals to Home Assistant, enabling low-latency, real-time control of smart-home devices via the Creative Console and Actions Ring; launched in beta on the Logitech Marketplace and reached 5k+ installs. More specifically, researched Matter and Home Assistant, set up a multi-device Wi-Fi/Matter testbed, and implemented a layered C# architecture using the Logi Actions SDK and Home Assistant WebSocket APIs, with dynamic device discovery, event-driven synchronization, debounced controls, and support for lights, switches, covers, and scripts. Designed, built and evaluated a real-time screen-to-light control pipeline for immersive gaming, using a TypeScript Matter stack to translate on-screen visual events into physical smart-light reactions and assess whether standardized Matter-based lighting can meet strict latency requirements. More specifically, built controlled latency-measurement tools, implemented real-time screen capture and image-processing components, generated and transmitted lighting commands over Wi-Fi to Matter-compatible devices, and analyzed end-to-end latency, throughput, bottlenecks, reliability, stability, scalability, and compatibility across smart lights from different manufacturers
