Professional Profile
I am a senior-level multidisciplinary engineer with extensive experience in software
development, cybersecurity engineering, DevOps, and security automation. My work
encompasses designing and developing complete systems across multiple technical layers, from
low-level software and embedded devices to backend architecture, web applications, network
infrastructure, cloud services, and security systems. My approach integrates both offensive and
defensive cybersecurity practices, along with automation and custom tool development to meet
specific technical requirements.

Software Engineering
Architecture & Engineering

Software Architecture: Design and implementation of complete software systems.
Backend Architecture: REST/API architecture, client-server systems, asynchronous and
concurrent systems.
Database Architecture: Authentication/authorization, role-based access control, task
queues, and caching.
Automation Platforms: Internal enterprise tooling and security-oriented applications.

Backend Engineering

Languages & Frameworks: Python (FastAPI, Django), C# (.NET, ASP.NET), C/C++,
TypeScript/JavaScript (Vue, Node.js).
Key Skills: Asynchronous networking, REST APIs, data processing, security tooling, backend
services, and embedded software.

Application & Platform Development

Traffic Management Systems: Development of platforms combining FastAPI, JavaScript,
Docker for real-time control and traffic analysis.
Security Systems: Development of anti-abuse systems including bot detection, IP-based
controls, and automated traffic analysis.

Cybersecurity Engineering
Offensive Security / Red Team

Penetration Testing: Red Team methodologies, network reconnaissance, web application
and API security, adversary simulation.

Defensive Security

Security Monitoring: Network, server, and traffic monitoring, event collection, anomaly
detection, and infrastructure visibility.
Data Protection: Designing mechanisms to protect systems and data from unauthorized
access, abuse, and data exfiltration.
Anti-DDoS Engineering: Traffic filtering, rate limiting, IP controls, and infrastructure
protection.

Security Monitoring & Intelligence Systems

Custom Systems: Development of data pipelines for monitoring, detection, alerting, and
response using Python, APIs, and custom dashboards.

OSINT / Digital Intelligence

Infrastructure Intelligence: Domain, DNS, subdomain discovery, network intelligence, and
exposure analysis.
Investigative Intelligence: Digital footprint and metadata analysis, information correlation,
and automated investigation workflows.

DevOps / DevSecOps
Linux & Containers: Experience with Arch Linux, Ubuntu, Docker, system services, process
management, and automation.
Cloud Infrastructure: AWS, Route 53, Cloudflare, VPS, cloud networking, and infrastructure
integrations.
Private Infrastructure: Proxmox-based server management, virtual machines,
containerized applications, and DNS management.

IoT / Embedded Systems
Platforms: ESP32, Arduino, Raspberry Pi, Embedded Linux.
Skills: Microcontrollers, IoT automation, device telemetry, and AI-enabled devices.

AI & Automation

AI Integration: LLM APIs, AI automation, intelligent agents, and AI-enabled embedded
devices.
Automation Engineering: Python automation, asynchronous processing, DNS automation,
deployment automation.

My Journey in Software Development
With a year of rich experience in software development, I've honed my skills by focusing on
the intricate realms of traffic-management systems and analytics, particularly within the
dynamic affiliate and traffic-arbitrage sectors, including numerous commercial projects.
For four enlightening years, I have shared my passion and expertise as an instructor in
cybersecurity and programming at IT FRIENDS, Kyiv, inspiring and educating others in these
crucial fields from February 2022 to January 2026.
My career path includes a rewarding stint as a developer at Binotel, where I enriched my
technical acumen from April 2021 to June 2021.
In addition, I served as a Software Developer and OSINT Developer (Team Lead) at Doctor
Online from July 2024 to December 2024, where I developed an OSINT platform for
collecting, processing, and analyzing open data, contributing to several commercial projects.
At T-Space, Kyiv, I worked as a Developer/DevOps from June 2025 to July 2026, further
enhancing my skills in commercial projects as a team leader, guiding talented teams to
achieve remarkable success and innovation.

Embedded: ESP32, Arduino, Raspberry Pi

Engineering Profile
Software Engineer: Design and implement complete applications.
Cybersecurity Engineer: Research attack paths and engineer defensive systems.

DevOps/Infrastructure Engineer: Manage Linux, cloud infrastructure, and deployments.
Security Researcher: Experienced in network and infrastructure research.
Systems Engineer: Connect various engineering domains from software to hardware.

Key Differentiator
My strongest asset is the ability to blend multiple disciplines, allowing me to approach
engineering problems as complete systems rather than isolated components. I am capable of
developing applications, building infrastructure, configuring networks, automating deployments,
monitoring systems, analyzing attack surfaces, and implementing defensive mechanisms.
