Hi, I'm Emanuel

Software Engineer ยท Backend Systems ยท APIs

I've spent 20 years building backend systems. The work I care most about is the kind where the engineering makes a real difference for real people: AI that removes friction humans shouldn't have to deal with, platforms that scale because someone thought them through, tools worth maintaining.

I'm curious about most things. I boulder, swim, and travel. I think about stoicism more than is probably normal. I also train using Mike Mentzer's HIT principles, and the idea of less volume, more intensity, done right, maps surprisingly well onto how I think about code. Let's chat about tech.

What Interests Me
โš™๏ธ

Backend Systems

How data flows, how APIs are structured, how infrastructure holds up under real load. I'm drawn to the work that lives closest to the fundamentals.

AI as a Tool

I've spent the last couple of years using AI as a development partner. What interests me is AI handling the volume work so the team can focus on problems that actually need judgment.

Movement & Discipline

I boulder, swim, and train using Mike Mentzer's HIT principles. The idea of less volume, more intensity, done right, applies further than just the gym.

If you want to talk engineering, AI, or compare notes on HIT training, I'm easy to find.

Selected Projects
PrismCV Project
PrismCV
Ruby on Rails
Docker
LLM / AI
API

PrismCV is an AI-powered resume and career intelligence platform. I architected the Ruby on Rails backend from the ground up, managed all Docker deployments, and ran systematic benchmarks across multiple LLMs to identify the optimal model for accuracy and cost-efficiency. The platform processes and enriches candidate profiles at scale, applying AI to surface insights that traditional parsing misses. Read more
