Work Experience

My tech journey kicked off at 12 with TeamSpeak servers, but professionally it began with Mikasa, a Discord bot I built in high school that grew to over 15,000 concurrent users across thousands of servers. Seeing it handle three million queries a month taught me the scaling systems and the importance of building things people actually use.

At Heybe-AI I automated content-processing workflows and cut daily review time from about six hours to roughly 1.2 hours using n8n, Flask, and Go workers on Redis queues. Fixing AI Chrome extension and bringing it to 99% reliability felt like turning chaos into order.

At Crypticorn I really leveled up. I turned a basic webhook handler into a FastAPI notification platform that now serves 77 million requests a month across Discord, Telegram, and email. I reduced API latency by about 25% (from 420ms to 315ms) and cut deployment errors by 40% with better CI/CD, lessons in how small, focused improvements make systems far more reliable.

Today I’m focused on Lunyn, building a Rust NASDAQ ITCH engine that targets sub-microsecond tail latency. Benchmarking against commercial feeds and getting interest from HFT firms keeps me excited to push the limits.

Along the way I’ve shipped tools like FlowState-CLI for productivity, an e-commerce API with Stripe integration, and IT Arsenal for DevOps automation.
