What I'm looking for

I'm looking to build real-time, scalable products across the full stack, with ownership of backend architecture, cloud infrastructure, and production systems.

I've built real-time systems for a 20,000-user chat application and TB-scale file automation platform as a freelance Full Stack Developer. I implemented Aho-Corasick multi-pattern matching for near-instant banned-word detection and shipped Node.js, REST API, and RabbitMQ-powered processing features.

I own production infrastructure end to end, including raw VPS deployment, Nginx configuration, security hardening, DNS, SSL, and ongoing maintenance. At The Small Data Store, I redesigned a multi-display React state architecture that avoided iframe cookie issues and shipped responsive layouts across desktop, tablet, and mobile.

I've also built reports and analytics with React, Go, and Python; implemented JWT authentication, file handling, queues, SMTP, WhatsApp integrations, and AWS deployments. My projects include a Next.js PWA for pet-care reminders, an LLM-powered task generator, and a CS2 highlight-download pipeline with Telegram delivery.
