Profile
Quantum computing researcher and Agentic AI architect with 20+ years of engineering leadership. Currently pursuing Quantum Machine Learning research at NIT Puducherry while leading technology strategy at Innoviti Technologies. Creator of open-source post-quantum cryptography platforms (QBITEL Bridge & QBITEL EdgeOS) that bring NIST-standardized PQC and AI-powered autonomous agents to enterprise legacy systems and critical infrastructure. Pioneering the convergence of Quantum ML, Post-Quantum Cryptography, and Agentic AI multi-agent orchestration to build quantum-safe, autonomously intelligent financial services platforms.
Open Source Projects
QBITEL Bridge — AI-Powered Post-Quantum Security Platform

Apache 2.0 | Rust + Python + Go + React/TypeScript
- Enterprise-grade platform that modernizes legacy systems using AI-driven protocol discovery and NIST Level 5 post-quantum cryptography (ML-KEM Kyber-1024, ML-DSA Dilithium-5)
- Agentic AI engine with 16+ specialized autonomous agents using LLM-powered multi-agent orchestration, confidence-driven execution (auto-execute >95%, escalate <50%), and zero-touch security response in sub-1-second (900x faster than manual SOC)
- AI protocol discovery engine reverse-engineers undocumented legacy protocols from raw traffic using Transformer classification, PCFG grammar inference, and BiLSTM-CRF field detection with 89%+ accuracy
- Polyglot 4-layer architecture: Rust data plane (PQC-TLS, DPDK), Python AI engine (LLM inference, multi-agent orchestration), Go control plane (OPA policies), React dashboard
- On-premise LLM support (Ollama-first) for air-gapped environments; domain-optimized PQC for banking (10K+ TPS), healthcare (64KB devices), automotive (sub-10ms), aviation (600bps)
QBITEL EdgeOS — Quantum-Safe Embedded Operating System
github.com/yazhsab/qbitel-edgeos
Apache 2.0 | Rust (no_std) | ARM Cortex-M + RISC-V
- Embedded OS protecting critical infrastructure devices (power grids, railways, defense) against quantum computing threats using NIST FIPS 203/204 compliant cryptography
- Full PQC stack: ML-KEM-768 key encapsulation, ML-DSA-65 digital signatures, FN-DSA-512, AES-256-GCM, SHA3-256 with constant-time operations and zero secret-dependent branching
- 10-crate Rust workspace including secure bootloader, preemptive kernel with MPU/PMP isolation, hardware-rooted identity (PUF/eFUSE), and mesh networking (LoRa, 802.15.4, BLE)
- Targets STM32H7/U5 (ARM Cortex-M7/M33) and SiFive FE310 (RISC-V); minimum 512KB flash, 128KB RAM with OTA A/B updates and Shamir secret sharing for key rotation
- Aligned with IEC 62443, EN 50129/50159, IEC 62351, and Common Criteria EAL4+ for industrial, railway, and power grid compliance
