Royal Kesava

Engineer with 3 years of combined experience spanning Train Control & Monitoring Systems (TCMS) engineering on the Vande Bharat project and backend software development. Skilled in C#, .NET Core, ASP.NET Core, GraphQL, SQL Server, and REST APIs, alongside strong expertise in embedded systems, communication protocols (Ethernet/TRDP, MVB, CAN, RS-485), and technical documentation (SYRS, ICD). Experienced in authoring safety-critical system requirement specifications, designing subsystem communication architecture, and building scalable backend systems using clean architecture principles.

Proven ability to transition across embedded and software domains while delivering mission-critical, production-grade solutions.

Backend Developer (2025-09 – Present)

• Developed GraphQL APIs using C# and.NET Core (HotChocolate).
• Designed SQL Server schemas with indexing, stored procedures, and optimized relations.
• Integrated Azure Blob Storage for document workflows.
• Built CRUD operations with filtering, pagination, and validation.
• Implemented Repository Pattern, Clean Architecture, and Dependency Injection.
• Resolved production issues including database constraints and performance bottlenecks.

TCMS Engineer – Vande Bharat Project at Saini Electrical & Engineering Works (2023-02 – 2025-08)

• Authored and reviewed System Requirement Specifications (SYRS), Interface Control Documents (ICD), and protocol documentation for Ethernet/TRDP, RS-485, and MVB.
• Designed TRDP-Ethernet frame formats and RS-485 protocol documentation, including MVB-over-RS-485 master/slave frame formats.
• Contributed to Safe Data Transmission (SDTV2) protocol design.
• Documented TCMS network architecture, subsystem schematics, and communication flows, including Braking and Battery Management System (BMS) interfaces.
• Defined requirements for Zero-Speed and Standstill Detection to ensure safe door and braking operations.
• Prepared structured test cases and simulation workflows, contributing to validation of subsystem communication.
• Hands-on exposure to propulsion converters, regenerative braking, pantograph/VCB, and train-level protections (EOL, EBL, HVAC, PA/PIS).
• Worked with communication networks including Ethernet, CAN, RS-485, Wire Train Bus (WTB), Ethernet Consist Network (ECN), and Ethernet Train Backbone (ETB).
• Gained exposure to Human-Machine Interface (HMI) systems.
