Leul Tewodros Agonafer

I combine strong algorithmic foundations with practical product experience: architecting PyTorch ML pipelines, shipping Flutter mobile apps, crafting full-stack ASP.NET systems, and creating immersive 3D graphics interfaces. A quick learner and versatile developer, I produce clean, production-minded code and visually thoughtful solutions ready to drive value in AI, web, mobile, or graphics roles. Portfolio grade: A+ (with published demos, metrics, and tailored ATS resumes for applications).
