Poland

Message

At Novasama Technologies, I engineered multi-party WebRTC video attestation for the official Polkadot app, including Metal-backed video rendering and synchronized animations. I also implemented encrypted, serverless messaging and an on-device search that returned results in 0.2–2.2 ms in benchmarking.

At Simble and KIWU, I led a cross-functional team of six across two production apps and architected a shared iOS framework for trip tracking, sensor processing, and networking. Earlier, I built mobile banking features at Bank BelVEB and developed an AR chemistry education app from its first public beta.
