Engineering Philosophy & Capabilities

Background & Foundation

Building Robust Systems Since 2020

I am a full-stack engineer and automation specialist with over 5 years of practical software development experience. My focus is at the intersection of high-performance backend systems, distributed data automation, and modern web applications.

Whether architecting custom video streaming proxies, building high-volume data pipelines, or launching full-stack SaaS platforms, I engineer clean, fault-tolerant solutions designed to scale reliably under real-world traffic.

Hands-On Code

High-Concurrency & Streaming

Architecting sub-second failover systems, HLS video pipelines, and high-throughput proxy servers using Go and Python.

Resilient Web Automation & Scraping

Building distributed data extractors, stealth crawlers, and automated workflows capable of handling complex anti-bot defenses.

End-to-End Product Engineering

Taking ideas from PostgreSQL database schemas and high-speed APIs to reactive, pixel-perfect frontend interfaces (SvelteKit / Next.js).

International Track Record

Delivered 50+ commercial projects for international clients, maintaining 100% on-time milestones and clean, maintainable codebases.
