Full-Stack Developer
Platform Engineer

Building complex, data-driven systems with deep understanding from processor architecture to distributed systems. I don't just write code—I understand how it becomes machine instructions.

About Me

What I Do

Full-stack developer at ModestTree Media Inc, building enterprise data platforms that modernize legacy systems. I architect distributed systems with offline-first sync, real-time collaboration, and multi-platform support—handling gigabytes of structured data across 20+ Docker containers.

My superpower is systems thinking: I understand how code translates to machine instructions, how garbage collection works across languages (Python, C#, Java, JavaScript), and how to make architectural trade-offs between client, server, and infrastructure. This foundation—from processor architecture to distributed systems—lets me design scalable solutions, not just implement features.

Currently pursuing a Masters in Computer Science at Concordia University while leading technical teams and organizing security community events.

Education & Experience

Concordia Innovation Lab — Software Engineer Team Lead

January 2025 - Present (Concurrent with ModestTree)

Readality VR Reading App: Lead 5-person engineering team. Designed technical architecture, authored design documents, conducted PR reviews, mentored team on Meta SDK. Hands-on development: hand-tracking interactions, performance optimization, backend integration. Balance leadership with 10+ hours weekly coding.

ModestTree Media Inc — Full-Stack Developer

September 2021 - Present (4+ years)

Enterprise data platform modernization. Distributed systems with offline-first sync, real-time collaboration, conflict resolution. Database optimization (10x improvements), Docker adoption (~20 containers), multi-platform architecture. Full-stack ownership: backend + frontend + infrastructure decisions.

Masters in Computer Science (In Progress)

Concordia University • Part-time

Focus: Computer Science fundamentals—operating systems, computer architecture, distributed systems. Building broad, deep understanding rather than specializing.

Bachelor's in Electrical Engineering

Polytechnic University, Odesa • 2014-2018

Foundation in hardware, electronics, and low-level systems programming

Projects

Infrastructure Lab

Production-Grade Home Lab

Self-hosted infrastructure treated as production environment: Proxmox virtualization, Docker services, VPN server, Nextcloud. Learning Terraform and Ansible through real implementation. Focus on observability, security hardening, backups, and automation—applying platform engineering principles to personal infrastructure.

Proxmox Terraform Ansible Linux

Personal Project • Ongoing

"Most of my professional work is under NDA, but I can discuss technical architecture, challenges solved, and design decisions in interviews."

GitHub: Very active (10+ commits/month), mostly private repos. Some CTF challenges and infrastructure configs will be public post-event.
