01 — About

Building end-to-end solutions across domains.

I'm a Full-Stack & AI Engineer with over two years of experience building production-grade software across various domains — from cybersecurity platforms and AI-driven tools to e-commerce solutions, social platforms, and medical management systems.

My expertise spans full-stack web development, applied AI & machine learning, secure backend architecture, and cloud infrastructure. I love turning complex problems into simple, scalable, and user-friendly solutions.

I work end to end — from designing data models and APIs to building responsive, modern interfaces — and I always prioritize clean code, performance, and security in everything I build.

Five systems. Five domains. One engineering standard.

Each project shipped as a complete product — architecture, security, and interface treated as one problem, not three.

SECURITY OPERATIONS

SIEM/XDR Cybersecurity Platform with AI Detection System

Real-time threat detection at scale

Built a scalable SIEM/XDR cybersecurity platform using a microservices architecture for real-time Windows threat detection. Developed backend services with NestJS and a React.js + Ant Design dashboard for alert monitoring, agent management, and analytics. Created a Go-based Windows agent integrating Sysmon/Winlogbeat with secure Kafka (mTLS) communication and self-healing capabilities. Implemented ML-based anomaly detection (Random Cut Forest) and integrated 1500+ Sigma rules mapped to MITRE ATT&CK. Deployed a zero-trust system using internal PKI, mutual TLS, and Docker infrastructure.

  • Modular microservices architecture orchestrated with Docker Compose
  • Go-based self-healing Windows agent with Sysmon/Winlogbeat integration
  • 17 Random Cut Forest anomaly detectors mapped to MITRE ATT&CK techniques
  • 1500+ Sigma rules for threat detection in OpenSearch with ECS normalization
  • Internal PKI (RSA 4096) and mutual TLS for zero-trust security

AI / TALENT INTELLIGENCE

AI-Powered Web Application for Talent Search and CV Management

Automated talent management & CV generation

ProfilFlow is a web application developed to automate and optimize talent management. It features a search and selection system, enabling efficient identification of suitable employees for specific missions. I implemented functionalities for comprehensive CV management, automatic updates with new skills and projects, AI-driven generation of professional CVs, and management of user roles and permissions, optimizing resource allocation and ensuring secure access while reducing administrative workload.

  • Automated CV data extraction via Azure AI Document Intelligence
  • AI-powered professional CV generation
  • Skills-based employee-project matching algorithm
  • Role-based access control system
