Summary
🤩
Rockstar🎓
Top SchoolDaniel Boll is a software development engineer with seven years of hands-on experience building scalable full-stack systems using C++, Rust, TypeScript and NoSQL databases. He holds a Computer Science degree from UNIOESTE and led a university functional programming study group, translating academic rigor into production-quality compiler and VM work implemented in Rust. Daniel has improved performance-critical systems—from parallelizing a C++ predictive species distribution model to contributing database integrity fixes in the Limbo project (a modern SQLite evolution) addressing WAL and io_uring edge cases. At Smart BR Soluções he drove major migrations and infrastructure upgrades (Next.js 11→13, Java 8→22, Docker Swarm→Kubernetes) and led marketplace integration planning as technical lead before focusing on search, CI/CD and scalability. Now at Amazon, he combines deep low-level systems experience with pragmatic e-commerce platform engineering and a habit of contributing to open source in his spare time. Notably, his background blends compiler/compiler-VM design, database internals, and production e-commerce integrations—skills that surface in both research and mission-critical engineering.
