Core Capabilities
Embedded Avionics Software
End-to-end development of airborne safety-critical firmware — bare-metal drivers, BSP/HAL, low-level peripherals, and ARINC 429/MIL-STD-1553B interfaces. ICD-driven real-time development, board bring-up, and hardware/software integration for defence and aerospace platforms.
Linux Application & Networking
Real-time Linux application development on SBC platforms using C and Python — multi-threaded architectures, deterministic UDP/TCP socket communication, and custom CLI diagnostic tools purpose-built for embedded aerospace environments.
Avionics Protocol Systems
Full-stack ARINC 429 and MIL-STD-1553B protocol software — BC, RT, and BM implementations on embedded platforms. Deterministic protocol stacks, real-time data exchange, and Qt-based simulators for ICD-driven interface validation and testing.
IV&V & DO-178C Support
Full-lifecycle independent verification and validation with rigorous DO-178C process compliance. Requirements-based testing, MC/DC structural coverage analysis, LDRA and IBM Rational RTRT toolchain expertise — with traceability, tool qualification, and audit-ready certification documentation.
LRU Test Bench Development
Integrated LRU-level verification platforms using Qt — protocol analyzers, GUI simulators, hardware interface validation tools, and automated ICD-driven test solutions for ARINC 429 and MIL-STD-1553B systems across aerospace and defence programmes.
