Vahagn A.

I bridge the gap between low-level system efficiency and cutting-edge decentralized technologies. With a deep focus on Modern C++ optimization, I build robust, scalable applications where every millisecond and every byte of memory counts. My expertise spans from professional Audio Plugin development to high-stakes Smart Contract security analysis and Generative AI infrastructure. Proprietary Cryptographic Engines: Architecting and developing custom Cryptographic Engines from scratch, tailored for specific security requirements and hardware constraints. Implementing high-speed encryption/decryption algorithms (AES, RSA, ECC) with optimized assembly or SIMD instructions. Ensuring mathematical rigor and resistance to side-channel attacks for private networks and decentralized protocols. System-Level Optimization & Security: Bare-metal programming and firmware development for embedded systems and specialized computational units. Performing deep-level code audits to eliminate memory leaks, race conditions, and security vulnerabilities at the binary level. Developing secure boot protocols and encrypted data-at-rest solutions for sensitive industrial and medical environments. Systems & Desktop Development (C++ / Qt / JUCE) Developing high-performance, cross-platform desktop applications using the Qt Framework and QML. Expertise in Modern C++ (17/20/23) standards, focusing on memory safety, multi-threading, and low-latency execution. Specializing in Audio Engineering: Designing custom VST/AU plugins and Digital Signal Processing (DSP) algorithms. Medical Device Control & Automation: Developing robust, real-time control software for diagnostic equipment and laboratory automation. Crafting mission-critical User Interfaces (UI) using Modern Qt/QML for medical monitors and device consoles. Seamless hardware-software integration for automated laboratory workflows. Blockchain & Web3 Security: Comprehensive Smart Contract Auditing (Solidity/EVM) to identify critical vulnerabilities and logic flaws. Advanced Gas Optimization: Reducing execution costs through deep bytecode analysis and efficient data structures. Developing automated tools for blockchain security assessment and formal verification. AI, Machine Learning & Automation: Architecting Generative AI workflows using ComfyUI, Stable Diffusion, and custom node development. Integrating computer vision models like YOLOv8, SAM, and LivePortrait into production environments. Managing high-load computational tasks on Cloud GPU infrastructure for seamless model inference and training.
