I'm Lucas Lopes, a software engineer who likes building things. I enjoy taking complex systems apart, making them simpler, and shipping products that feel good to use.

Experience

Dec 2021 - Present

Software Engineer

PhDsoft

Built an AI agent that acts as the main interface for a Digital Twin platform, letting users interact with the software, query documents through RAG, and operate the system through natural language. Led a MongoDB migration that cut critical query times and simplified the data layer. Built real-time 3D dashboards with Three.js so operators can monitor offshore oil rigs from a browser. Day to day, I write microservices in C#/.NET and build interfaces in Angular.

About Me

I like building things that solve real problems. Most of my time goes into writing backend services, wiring up AI features, and trying to make the end result feel good to use.

Lately I've been spending a lot of time with LLMs and retrieval-augmented generation. There's something exciting about making software that can understand context and actually help people get answers faster.

I'm still figuring a lot of things out. But I show up every day curious, I read a lot, and I care about writing code that works well and is easy to come back to.

B.S. in Computer Science from UNIFENAS, 2023.
