Lucas Sotelo

Senior Software Engineer · Buenos Aires

I'm a software engineer, graduated from UBA. For the last seven years I've been building backend and full stack products, mostly with Java, Spring Boot and React, with a focus on microservices and distributed systems, plus search and applied AI. I like owning a feature from design to measurable impact. Currently at Jobint.

Outside of work I explore new music, play a few instruments, do calisthenics and read science fiction and business history.

Selected projects

EthereumIPFSDistributed SystemsUniversity
Undergraduate thesis at the University of Buenos Aires: a decentralized wiki and a real-time chat built on Ethereum and IPFS, with no central server.

Beyond the implementation, the work includes a quantitative and qualitative comparison of both ecosystems for building decentralized applications.
