Work Experience
Head of R&D | Co-founder
Pipio.ai
- Co-founded a generative AI company called Pipio.ai as the technical co-founder and developed the technology that helped the company attract the first round of funding and grow.
- Built a generative AI company using in-house developed algorithms and models and the backend render service.
- Collaborated with my co-founder and successfully raised capital and grew the R&D team and company.
Machine Learning Lead
Helm.africa
- Developed a natural language processing (NLP) and computer vision service to build task-oriented conversational agents for low-resource languages. Technologies include transformers, PyTorch, Torchvision, Flask-RESTful, and PostgreSQL.
- Created intent classification, sentiment, and entity extraction models that rely on various deep learning and classical machine learning techniques to accommodate various languages. Used transformers, scikit-learn, PyTorch, and TensorFlow.
- Developed a machine vision-based quality assurance application with a machine vision camera interface. The technologies include Torchvision, Flask-RESTful, GenICam, and React. Used deep transfer learning to improve sample efficiency of clients' data.
Research Group Leader | Principal Research Scientist
Council for Scientific and Industrial Research
- Developed a real-time image processing framework as well as image enhancement, target detection, object tracking, and state estimation algorithms.
- Developed software interfaces to hardware devices like cameras, pan-tilt-zoom systems, communication radios, and real-time clocks.
- Led the company's image processing team of full-time employees and students, published some papers, and helped with talent management and screening.
Senior Research Scientist, Optronic Sensor Systems
Council for Scientific and Industrial Research
- Developed models for a physically based optronics scene simulator. The models were developed in C++ and an in-house 3D modeling tool.
- Developed physically based renderers for the long and medium-wave infrared bands. The full software and hardware accelerated renderers were developed in C++ and OpenGL with GLSL. The rendering algorithms ranged from simple to path tracing.
- Developed physically based renderers for the short wave (reflective) and visual bands. The software and hardware accelerated renderers were developed in C++ and OpenGL with GLSL. The rendering algorithms ranged from simple to path tracing.
Senior Research Scientist, Modelling and Simulation
Council for Scientific and Industrial Research
- Developed a faster-than-real-time distributed modeling and simulation framework for wargaming-type simulations. The simulation framework was implemented in C++ and employed TCP communication between the nodes.
- Built vehicle and equipment models for wargaming-type simulations. The models ranged from behavioral to physically based and were implemented in C++.
- Created a 3D simulation viewer and analysis tool using OpenSceneGraph and osgEarth.
