Hire the Best Python Numpy Developers
in South Africa

I am an experienced quantitative software developer with over 7 years of Python development experience, primarily focused on automated trading and backtesting. I bring a wealth of expertise in quantitative development, particularly with the powerful backtesting library, Vectorbtpro, hyperparameter optimization libraries Optuna and Raytune and machine learning and neural networks centered around the ecosystem of Tensorflow and Scikit-learn. My primary skill set includes: - Programming Languages: Python - Data Manipulation: Pandas, Polars, Numpy, Numba - Backtesting Libraries: Vectorbtpro - Technical Analysis Libraries: Ta-lib, pandas-ta - Machine Learning and Optimization: Tensorflow, Scikit-learn, Autokeras, Optuna, Mlflow, Raytune, along with several ML models such as XGBoost, Catboost, LSTM, MLP - Scripting: Pinescript - Databases: MySQL, SQLite, PostgreSQL - Web Development: Django, Flask, FastAPI, Streamlit - API Integrations: REST API, Websockets - Message Brokers: Redis Recently, my passion project has been building a backtesting and trading framework that aims to bridge the gap between backtesting and optimization with live trading, such that they operate seamlessly together, to ensure live trading is both as optimized as possible and runs as close to our backtests as possible. It also includes a machine learning module to make it easy to train and integrate machine learning models into your strategies. In addition, I am highly experienced in backend web development and can take any trading and/or backtesting system from paper to a robust, scalable, modular system with all the feaures you might want such as API integrations, analytics, automatic notifications, authentication controls, etc. I'm also experienced in Streamlit frontends and have worked on a variety of projects from both the front and backend perspective to bring together a unified user experience for backtesting and trading. If you’re looking for a developer who not only understands the technical depth of quantitative systems but also how to design, scale, and integrate them into real-world trading environments, I can help bring that vision to life. Whether you need a full trading framework, a custom machine learning pipeline, or an optimized backtesting engine, I can architect and implement a solution tailored to your goals. I appreciate you taking the time to assess my profile, feel free to reach out to discuss your project needs and let's work out how I can help you achieve your trading goals.

I am a developer with some experience tinkering with small projects. I have prior experience in various programming languages - namely: - C - at a low intermediate level (with familiarity with tools like Valgrind (memory management), GDB (debugging), clang-format (code formatting)) - Python - at a advanced level, with familiarity with package management tools like poetry, environment management tools like pip-env, and code formating tools black/flake8/ruff, as well as having a beginner-intermediate level understanding of multiple mathematics/data science/machine learning frameworks namely - Numpy, Pytorch and Pandas, and experience web-scrapping with BeautifulSoup and Selenium. - Java - at an intermediate level - Bash - basic beginner level, with some basic commandline scripting experience Additionally, I have experience working with Microsoft's Office Suite - namely PowerPoint, Word, and Excel, so I am capable of preparing and presenting presentations if needed.

I am an Senior Software Developer and part time university student currently pursuing a Bachelor of Science in Computer Science and Mathematics seeking to contribute to your Software Development department through a full time position. I have worked at LottoStar (1609 Group) beginning as a Junior Developer in February 2019 and advancing to Intermediate in June 2020. I attribute my quick rise to willingness to learn and work above and beyond my given requirements. I started out primarily on the backend working with Python, Django and Postgres and then later PHP and Phalcon. Once we expanded Expanded our codebase I shifted towards both backend and frontend development using HTML, CSS and pure Javascript at first and then later the React framework. This improved my skills using and designing APIs on the back and front end. One of our most difficult tasks, which I was a primary member of, was upgrading our software on the backend as our versions of Python and Django were deprecated.
