Frequently Asked Questions

Why hire Python developers from Serbia?

Serbian Python developers offer deep expertise in AI/ML, data engineering, and backend development at 40-60% lower costs than Western Europe. Our developers are experienced with modern Python ecosystem, work in CET timezone for real-time collaboration, and have strong computer science fundamentals essential for complex Python projects.

What Python frameworks do your developers use?

For web development, we use Django for full-featured applications and FastAPI for high-performance APIs. For ML/AI, we work with TensorFlow, PyTorch, and Scikit-learn. For data engineering, we use Pandas, Apache Airflow, and various ETL tools. We also have expertise in LangChain for LLM applications.

Can you build AI and machine learning solutions?

Yes, AI/ML is one of our core strengths. Our Python developers build custom ML models, deep learning systems, NLP applications, computer vision solutions, and LLM-powered applications. We handle the full ML lifecycle from data preparation to model deployment and monitoring.

Do you work with LLMs and generative AI?

Yes, we have extensive experience with LLM integration using OpenAI APIs, LangChain, and vector databases like Pinecone and Weaviate. We build RAG systems, chatbots, document processing pipelines, and custom AI assistants tailored to your business needs.

What about data engineering and ETL?

We build robust data pipelines using Python with tools like Apache Airflow for orchestration, Pandas for transformation, and various connectors for data sources. We design data warehouses, implement real-time streaming, and create analytics platforms.

How do you handle ML model deployment?

We deploy ML models using containerization (Docker), cloud services (AWS SageMaker, GCP Vertex AI), and custom FastAPI endpoints. We implement MLOps practices including model versioning, A/B testing, monitoring, and automated retraining pipelines.
