Cristovão Neto
@cristovoneto
Full-stack engineer improving APIs, building tools, and shipping React/Node.js products.
BrazilWhat I'm looking for
At LSI - Information Systems Laboratory, I’ve worked on a Spring Boot bidding and contracts system, making API responses much faster by creating optimized SQL Server views.
I also architected an auditing tool for 452 public entities in Paraíba, using web scraping and LLMs in Node.js, and I’ve mentored five junior developers through coaching, task allocation, and code reviews.
Previously at Diletta Solutions (remote), I built frontend features in Next.js and helped US-based stakeholders by presenting changes in English and feeding their feedback into the product roadmap.
I also founded Decifrando, a SaaS for Catholic musicians that generates chord charts and PDFs, and I’ve instrumented acquisition tracking with PostHog, UTM tracking, and A/B tests.
