Senior🎓
Top SchoolJeferson Lima is a Senior Software Engineer and team lead with 12 years of experience building scalable web and embedded systems from Brazil's Bahia. He combines deep algorithmic skills (graphs, dynamic programming, greedy techniques) honed in programming marathons with practical expertise in backend (Node.js, Ruby, Java, Kotlin), cloud infrastructure (AWS, GCP, serverless/Firebase) and performance-driven platform work. He has led engineering teams, cut costs through low-cost serverless designs, and delivered large storage and stability improvements in production systems (e.g., 80% storage reduction and CDC stability work). An avid hardware tinkerer and IoT researcher from his UFBA days, he cofounded two startups that merged electronics and cloud backends, giving him uncommon end-to-end product insight. He also mentors and teaches data structures, system design and interview prep, translating deep technical knowledge into clearer, hire-ready engineers. Practical, curious and entrepreneurial, he thrives at the intersection of embedded devices, backend architecture and developer productivity.
