• Code quality and best practices: Write clean, maintainable, and well-documented code, adhering to best practices in software engineering.

• Testing and validation: Develop comprehensive unit and integration tests to ensure the reliability and accuracy of our AI retrieval systems.

• API development: Build and maintain REST and GraphQL APIs using frameworks like FastAPI and Flask to expose our AI retrieval capabilities to other services and applications.

• Streaming and cancelable endpoints: Implement streaming responses and cancelable endpoints to support real-time and interactive use cases, such as model output.

• Continuous improvement: Stay up-to-date with the latest developments in AI and software engineering, and continuously improve our systems and processes.

• Language fundamentals: Proficient in Python, with a strong understanding of data types, string manipulation, type casting and conversions.

• Functions: Experienced in calling functions, using default and variable arguments, and writing lambda functions.

• Virtual environments: Familiar with tools like venv, virtualenv, pipenv, and poetry for managing project dependencies.

• File handling: Skilled in reading, writing, and manipulating files in Python.

• Error Handling: Expert in handling errors and exceptions to ensure robust and reliable code.

• Datamodels: Knowledgeable in designing and using data models to represent and manage data efficiently.

• Context managers and logging best practices: Proficient in using context managers and implementing logging best practices to maintain code clarity and traceability.

• Inheritance and method overriding: Experienced with object-oriented programming concepts, including inheritance and method overriding.

• Magic methods: Familiar with Python's magic methods to enhance the functionality of custom classes.

• Code formatting: Adheres to code formatting standards using tools like black, isort, flake8, and pylint.

• Testing: Strong background in testing methodologies, including unit testing with pytest, mocking, and integration testing.

• Versioning: Familiar with semantic versioning and maintaining changelogs to track changes and updates.

• Data structures: Proficient in using stack, queue, and priority queue data structures (via collections) to manage and process data efficiently.

• Functional programming: Experienced in functional programming concepts such as map, filter, reduce, generators, and decorators.

• Async programming: Skilled in asynchronous programming using asyncio, aiohttp, async generators, and handling timeouts with wait_for.

• Threading vs multiprocessing: Understands the differences and trade-offs between threading and multiprocessing, and can choose the appropriate approach for different tasks.

• Memory and performance profiling: Proficient in using tools like tracemalloc and cProfile to identify and optimize memory usage and performance bottlenecks.

• API development: Experienced in developing and maintaining REST and GraphQL APIs using frameworks like FastAPI and Flask.

• Streaming responses and cancelable endpoints: Capable of implementing streaming responses and cancelable endpoints to support real-time and interactive use cases.

• Machine learning experience: Familiarity with machine learning frameworks and libraries such as TensorFlow, PyTorch, or scikit-learn.

• Natural Language Processing (NLP): Experience with NLP techniques and tools, such as spaCy or NLTK.

• Distributed systems: Knowledge of distributed systems and experience with tools like Kubernetes or Docker.

• Cloud services: Experience with cloud platforms like AWS, GCP, or Azure.

• Open source contributions: Contributions to open-source projects or a strong portfolio of personal projects.
