Product focus

Full focus on scalability, performance, and smooth UX — bringing together everything I refined over years of React Native, real-time backend, and interactive maps experience.

Charging Station Management — OCPP

Full implementation of the OCPP 1.6 and 2.0 protocol on both the backend (Node.js) and the React Native app. The system manages electric vehicle (EV) charging stations in real time, including charge point authentication, session start and stop, status monitoring, recharge history, user and tariff management, as well as remote alerts and diagnostics — all integrated into the app's main flow.

Real-Time Communication — WebRTC

Full WebRTC support on the backend (signaling server with Node.js and Socket.io) and the React Native app. Enables P2P video and audio calls with low latency, ICE candidate exchange, media stream management, TURN server support for restricted environments, and native integration into the app's service flow — ensuring smooth and secure communication between users.
