I'm a Backend Engineer and Data Scientist with professional experience building scalable backend systems and developing data-driven solutions using machine learning.
Most of my production work has been done in private repositories for startups and client projects, but I maintain public showcases and detailed summaries to demonstrate my technical depth, problem-solving approach, and engineering practices.
- Backend system design & RESTful APIs
- Wallets, payments, and transaction systems
- Authentication & role-based authorization
- Data analysis, machine learning, and model building
- Translating data insights into production-ready systems
- Cross-functional collaboration (backend, frontend, data)
- Languages: Python, JavaScript
- Frameworks: Django, Django REST Framework, FastAPI, Node.JS, Express.JS
- Databases: PostgreSQL, MySQL, SQLite, MongoDb, GraphQL
- Auth & Security: JWT, Role-Based Access Control
- Payments: Paystack, Stripe, Flutterwave, wallet & settlement flows
- Async & Realtime: Celery, Django Channels, WebSockets
- DevOps: Linux, Gunicorn, Nginx, AWS
- Languages & Tools: Python, R, Pandas, NumPy
- Visualization: Matplotlib, Seaborn
- Machine Learning: scikit-learn, Tensorflow
- Techniques: Data cleaning, feature engineering, model training & evaluation
- Use Cases: Prediction, classification, analytics-driven decisions
- Core: HTML, CSS, JavaScript
- Framework: React
- UI: Bootstrap, responsive layouts
- Integration: REST API consumption
- Git & GitHub
- Postman
- Docker
- AWS
Most client and startup projects are private due to NDAs.
