Profile

I am Blaise Ndayishimiye, a versatile software engineer building products that real people use every day. My work spans mobile development, institutional software, intelligent data systems, and AI research.

I founded HelixNova™ Inc, a technology company operating out of Canada, focused on delivering production-grade software across industries.

I have a strong focus on language technology and NLP — building digital tools that preserve and extend the reach of African languages. Currently fine-tuning LLaMA for agent-based workflows and applied AI systems.
