About

I am a Cybersecurity Engineer working across security engineering, systems engineering, software development, automation, and applied security research.

I approach cybersecurity as an engineering discipline: understanding how systems behave, designing controls into the architecture, building dependable technical solutions, validating them with evidence, and improving them continuously.

Professional Domains

🛡️ Security Engineering

Designing secure architectures, strengthening defensive capabilities, and improving the resilience of enterprise environments through engineering-led security practices.

📡 Detection Engineering

Developing, validating, and refining detection logic with a focus on behavioral analytics, telemetry quality, alert reliability, and measurable defensive visibility.

🖥️ Systems Engineering

Designing and operating scalable, maintainable, and secure infrastructure with attention to availability, identity, access, observability, and operational continuity.

💻 Software Development

Building backend services, internal platforms, integrations, and technical tools with secure, maintainable, and scalable software architecture.

⚙️ Security Automation

Creating repeatable workflows that reduce manual effort, improve consistency, accelerate technical validation, and support reliable security operations.

🧪 Applied Security Research

Investigating practical security problems, system behavior, defensive methods, and emerging technologies through experimentation and evidence-driven analysis.

Engineering Approach

Understand the system
        ↓
Design security into the architecture
        ↓
Build dependable technical solutions
        ↓
Validate behavior and control effectiveness
        ↓
Improve reliability, resilience and visibility

My work connects infrastructure, software, telemetry, security controls, and operational processes rather than treating them as isolated disciplines.

Technology Stack

Languages & Runtime

Python, JavaScript, TypeScript, C#, C++ and Node.js

Backend & Application Engineering

Django, Flask, FastAPI, Express.js, Next.js, React and Electron

Systems, Data & Delivery

Linux, Docker, Nginx, PostgreSQL, MySQL, Git and GitHub Actions

Selected Focus

  • Secure architecture: integrating security requirements into system and software design.
  • Reliable detection: improving the quality, coverage, and operational value of defensive analytics.
  • Resilient infrastructure: engineering systems that remain observable, maintainable, and dependable.
  • Security-focused development: building services, integrations, and tooling with security as a design constraint.
  • Operational automation: transforming repeatable technical processes into consistent engineering workflows.
  • Practical research: testing ideas against real system behavior instead of relying only on theory.
