AI Development with Python

Predictive Analytics with Python

Get forecasts based on trends. After collecting and analyzing historical data your company is interested in, we train a Python model to detect patterns and, on this basis, predict future sales, recognize early signs of illness, detect fraud, and whatever else you’re looking for immediately after encountering new data. Before training, we clean your datasets, study them to select the features that have the strongest relationship with the predicted variable, then split the dataset into training and test data. To train models, we use algorithms (decision trees, K-means clustering, time series, Naive Bayes), Python libraries (pandas, NumPy, matplotlib, seaborn, and scikit-learn), and Python native functions. After training, we evaluate the performance of your model before deploying it into a real-life application.

Python Image Recognition

Recognize objects in real-time in new images or videos. We create image recognition models for use cases you asked for, including user age identification by faces, disease detection, and more. For tasks like classification and segmentation of images, converting written text on paper into digital text, object/action detection, and tracking in videos, we use convolutional neural networks. Before training, we can use available image databases or prepare your images by preprocessing them (adjusting to the same dimensions, scaling pixel data to a standard range, etc.) and augment them by rotating, zooming, injecting noise, etc., to prevent overfitting (memorizing only examples seen before). After training and evaluating the model, we integrate it into a web or mobile app, or deploy it to a cloud platform.

End-to-End Python Development Services

Belitsoft is a TOP Python development company that offers top-tier web and mobile applications, as well as websites.

Python Development Company for Startups

Even after growing into industry giants, many big startups continue to use Python due to its startup-friendly nature. If your project involves large data loads, big data, data visualization, machine learning/artificial intelligence, consider Belitsoft. Our Python developers quickly transform your ideas into reality, build an MVP as soon as possible to attract investment, easily scale the product by adding new features to meet market demands, and integrate smoothly with other software related to your product.

Python Consulting

Our Python consulting company provides expert solutions for healthcare, finance, e-commerce, education, transportation, and more, on how to best use Python. We either develop plans for integrating Python into your operations, or evaluate your existing systems through comprehensive code analysis, security audits, performance evaluations, and scaling assessments to prepare clear documentation with recommendations.

Python Enterprise Development

Our Python development team build applications for enterprises, integrate them with existing legacy databases and non-web applications written in C++, C# (along with its broader Microsoft .NET platform), and Oracle Java. They write code to integrate disparate applications and integrate with LDAP or Active Directory authentication systems. These may be corporate intranet and collaboration platforms like those used by this U.S. government agency or any other type of enterprise systems.

Python 2 to 3 Migration

For companies which have outdated applications with older Python backends with the end of support, we assist with Python migration and application conversion, especially when backwards compatibility is important. We adapt the source code to a newer version using libraries like 2to3, python-future, and six, identify incompatible source code and rewrite it. After porting the source code to Python 3, we conduct testing.

Python Refactoring

Unmaintainable apps have a very real cost. Clean and simple Python code that is well laid out and easy to follow saves time and money in the long term. Less time will be spent on maintaining, testing, and making changes. Future developers are more likely to update easy-to-read and understandable code without needing to rewrite the application from scratch.

Python Automation QA

Our experienced QA engineers design and develop automated tests for the web in close collaboration with the development team, maintain the required test documents (test cases, reports, etc.), and perform performance testing. They are experienced in backend test automation, web UI test automation, and understand the BDD approach, SDLC and QA processes, best practices, testing techniques, and methodologies.

Python Integration Services

Java with Python. We can either invoke Java functionality from Python and call Python functions from Java via a bridge like Py4j, or port the original implementation to the JVM. If you have a Java application project in the machine learning domain and want to integrate it with an irreplaceable third-party library available only in Python, we know the best ways to do that, allowing execution to switch seamlessly between the platforms. You will not encounter any stability issues.

Angular with Python. If you’re not happy with the way you currently implement UI, we are here to help. Angular is a natural choice for UI as well as Python for API. There are three general options to marry them: Angular HttpClient to make REST API calls; Angular's WebSocket client to receive updates in real-time; a message queue like RabbitMQ for asynchronous communication. Our developers will build nice frontends to efficiently visualize and manage your data.
