Job description
Job Summary: We are looking for an experienced Python Developer to design, develop, and maintain high-performance applications. The ideal candidate should have a strong background in backend development, APIs, databases, and cloud technologies. Key Responsibilities: • Develop, test, and maintain scalable Python applications. • Build and optimize RESTful APIs and microservices using frameworks like FastAPI, Flask, or Django. • Work with databases (SQL and NoSQL) such as PostgreSQL, MySQL, MongoDB, or Redis. • Integrate and automate workflows using Python scripting. • Optimize application performance and troubleshoot issues. • Collaborate with frontend developers, DevOps teams, and data engineers. • Implement unit testing, integration testing, and debugging. • Work with cloud platforms (AWS, Azure, GCP) for deployment and scaling. • Document technical solutions and follow best coding practices. Required Qualifications: • 6+ years of experience in Python development. • Strong experience with web frameworks (FastAPI, Flask, Django). • Hands-on experience with SQL and NoSQL databases. • Knowledge of Docker and containerized applications. • Experience with Git, CI/CD pipelines, and deployment automation. • Solid understanding of OOP, design patterns, and software architecture. • Familiarity with asynchronous programming and multiprocessing. Preferred Qualifications: • Experience with message brokers (Kafka, RabbitMQ, or Redis Streams). • Familiarity with data processing libraries (Pandas, NumPy, etc.). • Experience in serverless architectures and cloud functions. • Knowledge of AI/ML frameworks (TensorFlow, PyTorch, Scikit-learn) is a plus.
