I am a full-stack software engineer and founder of HelixNova™ Inc, a technology company based in Canada. I design and build cross-platform software, intelligent systems, and institutional platforms — from mobile apps on the Play Store to enterprise-grade desktop software.
My work spans Flutter mobile development, Java and C# backend systems, machine learning pipelines, and Linux infrastructure. I have a strong focus on language technology and NLP — building tools that preserve and extend the reach of African languages. Currently fine-tuning LLaMA for agent-based workflows and applied AI systems.
