ABU DHABI, UAE // 24.4539° N, 54.3773° EArchitecting Resilient C4ISR Systems, Tactical Data Links, RF Infrastructure & Sovereign Embedded Solutions.
With over 14+ years of progressive engineering leadership in Abu Dhabi, I specialize in bridging legacy defense platforms with modern Command & Control (C2) ecosystems. From patent-pending anti-jamming/anti-spoofing navigation architectures and bare-metal MIL-STD-1397 Type A (NTDS) hardware gateways to mission-critical naval combat communications and multi-band RF spectrum operations, I deliver sovereign capability from the circuit level up to strategic C4ISR integration.
Full-Spectrum Technical Architecture
End-to-end engineering authority spanning physical RF propagation, high-voltage legacy military bus conditioning, bare-metal firmware, and tactical C2 software.
C4ISR & Tactical Data Links
Deep protocol and hardware-level mastery of maritime and joint tactical data links. Specialized in naval combat system integration, Data Link Processor (DLP) interfacing, DTS/modem synchronization, and multi-platform C2 interoperability.
RF Engineering & Navigation Warfare
Mission-critical HF/VHF/UHF tactical radio infrastructure, satellite communications subsystems, and resilient Positioning, Navigation, and Timing (PNT). Inventor of patent-pending ground-based anti-jamming and anti-spoofing navigation technology.
Embedded Hardware & Bare-Metal Design
Custom hardware interfaces and deterministic bare-metal C (C99) firmware. Designing opto-isolated high-voltage level shifters (`-15V` to `+3.3V` CMOS), high-speed microcontroller gateways (ARM Cortex-M / Teensy), and hardware-in-the-loop (HIL) diagnostic instruments.
C2 Software, Networking & Industrialization
Architecting cross-platform Python Command & Control software, real-time TCP/IP socket telemetry engines, and virtualized Linux server clusters (Proxmox). Combining hands-on R&D with executive defense industrialization and turnkey proposal leadership.
Featured Engineering Portfolio
Legacy MIL-STD-1397 (NTDS) to Modern C2 Gateway Topology
MIL-STD-1397 Type A Parallel Interface
Legacy naval combat systems and Link 11 Data Terminal Sets communicate over parallel NTDS buses using inverted high-voltage negative logic: 0 VDC = Binary 1 and -15 VDC = Binary 0 across 24 input lines and 26 output lines with asynchronous handshake strobes (EF, IDR, ODA).
14+ Years of Defense & Telecom Leadership
Defense Communications & Naval Systems Consultant
Directed mission-critical naval telecommunications integration, Link 11 tactical data link infrastructure, and ship-to-shore C4ISR interoperability for the UAE Navy. Engineered custom hardware/software diagnostic solutions and resolved complex multi-vendor combat system interfaces.
Awarded an Official Certificate of Acknowledgment by the Chief Commanding Officer of the UAE Navy in recognition of outstanding technical contributions to military telecommunications systems.
Co-Founder — Technical & Commercial Lead
