About

I am Érick Lúcio, a Software Developer and Computer Science student at UNESC. I work on APIs, data and systems that need to move from text to operation.

I also work with applied AI when it brings clear value. I prefer combining model, rules and validation instead of relying on prompts alone.

Areas of work

Backend

REST APIs, authentication, authorization, integrations and persistence with maintainability in mind.

Applied AI

LLMs connected to real systems with RAG, normalization and rule-based validation.

Data

Modeling, SQL, PostgreSQL, MySQL, MongoDB and data preparation for analysis and automation.

Delivery

Docker, CI/CD, observability, deployment and architecture decisions with cost and operations in mind.

How I work

I cut what sounds good on paper but fails in practice.
When AI is involved, it needs rules, validation and a source.
I can work full-stack when needed, but backend stays my core.

Available for
