About

My name is Justin DaCosta, and I'm currently working as a Machine Learning Engineer at Amazon AGI in the Bay Area. Before that, I worked on ML for Route 53, and created the Route 53 Firewall Advanced service, that allows realtime detection and blocking of malicious requests. I've been working as a software engineer for almost 10 years, at everywhere from small individual freelance jobs, to startups, to huge distributed systems handling trillions of requests per day.

I'm still fairly new to LLMs and AI being my primary day to day focus, but this blog will be a place for me to write about my experiences and learning, as well as a place to share my ideas and thoughts regarding how to make AI smart, fast, and cheap. My hope is that I may be able to combine my insights from working in low latency and high throughput distributed systems with my knowledge of LLMs to help build the next advances for universally useful AI.

As Paul Graham once wrote, "If you're not writing, you're not thinking." So bear with me as I attempt to think out loud.

I generally develop on either a Macbook, or a custom Linux machine running Ubuntu with Omakub. My daily driver keyboard is a Kinesis Advantage 360 Pro, and my daily driver watch is a Sinn 556i.
