Current engineering
Transforming live GPS data into route context, station state and passenger-facing information—while keeping the implementation robust for an embedded railway environment.
The public-safe view of my current work: route matching, station state transitions, next-station distance, train speed, ETA and resilient GPS source coordination.
Railway systems
Case studies focus on the engineering responsibilities and public architecture, without exposing proprietary code, customer-specific network details or internal protocols.
AC COACH PLATFORM
Embedded processing platform used in First AC, Second AC and Third AC coaches for passenger information, route-aware operation, device coordination, monitoring and diagnostics.
EMU / MEMU PLATFORM
Driver-facing embedded control and monitoring application for a large train-wide ecosystem spanning passenger information, displays, CCTV, communication and supporting subsystems.
