Summary
🤩
Rockstar🎓
Top SchoolIgor Coelho is an experienced computer science professor and researcher based in Rio de Janeiro with 15 years of experience designing high-performance computing and combinatorial optimization solutions. He develops applied research across CPU/GPU acceleration, metaheuristics, smart grids, transport logistics (drone/truck/train/ship), graph theory, microcontrollers and distributed web/blockchain applications. As an active open-source contributor he has improved core NEO blockchain components and the NEO VM—adding caching, opcode documentation, stack isolation and performance-focused refactors that enhance consensus and transaction handling. His academic career includes a doctorate in Algorithms and Optimization and faculty roles at UERJ and UFF, where he blends theoretical rigor with practical system-building. Unusually for an academic, he pairs low-level GPU and microcontroller work with blockchain backend engineering, enabling cross-domain solutions from embedded devices to distributed ledgers.
