Python experts can wear many hats and specialize in multiple fields from AI and ML through web development to game dev. Depending on your business needs we can help you find a Python developer with relevant experience.
Python machine learning engineers
To boost your business with machine learning, you don’t necessarily need to integrate expensive feature-loaded ML solutions into your systems. A freelance Python contractor can solve many ML problems using simple tools. They can help you apply linear regression algorithms for predictions or Bayesian classifiers for filtering documents. They also can build an AI solution for image recognition, text, and data processing. For complex tasks, they can create and train neural networks using APIs for deep learning libraries.
If you need to build a real-time computer vision application, you can hire OpenCV developers who code in Python. Using OpenCV-Python API, they can solve tasks on image processing, video capture, and analysis to build such app features as face detection and object detection.
If you want to prototype, train, and deploy a scalable deep learning model, you can hire Keras developers. Using the Keras Python API wrapping Theano and TensorFlow numerical computation libraries, Python programmers can build a neural network in a few lines of code.
Python data engineers and ETL pipelines
Many Python developers have a good understanding of relational (MySQL, PostgreSQL, MSSQL) and non-relational (MongoDB) databases. They also are experts in algorithms that collect, cleanse, and validate data. Whether you need to build a custom BI tool or a web scraping and aggregation pipeline, a Python programmer will be of help.
Using Pandas, SciPy, NumPy, and other Python data science modules, programmers can create powerful tools for data manipulation and analysis. You can hire Pandas, Numpy, ad SciPy developers to build ETL pipelines that will import data from various file formats, such as JSON, SQL, or Microsoft Excel, and execute various data manipulations such as merging, reshaping, selecting, and cleaning. Python data engineers have all tools needed to write reliable scripts that integrate multiple data sources and databases into one system.
Moreover, Python engineers are good at visualizing data. They successfully use Matplotlib and Seaborn libraries for plotting graphs. For advanced interactive visualization of 3-D data, they can use the Mayavi app. Those tools make creating beautiful custom charts simple.
Python programmers and DevOps
Python experts can help you improve your team’s development lifecycle. They know how to write reliable scripts to automate your CI/CD pipelines and orchestrate your infrastructure. Those scripts are platform-independent and usually work well with version control systems, configuration management tools, and automation testing frameworks.
Developers building APIs with Python
If you have a bunch of services on the backend of your web app, a Python web developer can help you orchestrate them. Python is a good language for creating highly scalable APIs and gluing pieces of software into great microservice architecture. The PyTest framework allows writing effective unit and functional tests for Python API and helps developers ensure flawless operation of your app. In this view, engaging a Python programmer in your next API interaction project would be a smart decision.
Python web backend development
Python web developers are good at building web services. For fast development, they have several Python web frameworks at hand. For example, they would use Django for sophisticated, multi-layer, full-stack apps or Flask for building small and simple projects.
Python engineers building desktop apps
You can ask a Python engineer to build a desktop application for you. They’ll choose the right GUI framework for the platform you target. Apart from the Python’s standard GUI library Tkinter, there are a couple dozen cross-platform and platform-specific GUI toolkits, such as PyGUI, wxWidgets, Kivy, PYQT, etc.
Python game developers
Using PySoy and PyGame libraries with popular game engines, Python developers can create a game prototype within a few days. Or they can build a production-grade game for you. Such popular games as Battlefield 2, Frets on Fire, and World of Tanks, for example, were written in Python.
