Python is my main programming language and I love it. There are many advanced topics like decorators, context managers, generators, metaprogramming that can massively improve your skills. Python OOP, when applied correctly, is an insanely powerful tool. The ability to see into the "matrix" of Python is a key skill: I can help you to develop it and boost your productivity.

I know ins and outs of Django and contribute to its open-source development, as well as use it for a day-to-day job. I can help you to create readable and maintainable architecture, design data structure, write ORM queries of any complexity without the need for raw SQL, debug any issues, and efficiently optimize your application. I am also proficient in DevOps and can help you deploy your app to any server or debug deploy problems.

I have experience writing and optimizing real-time complex (>250 lines long) queries on 10s of millions of data points. I can really feel the data and it's relations, and can help you to design a normalized data structure and create a query of any complexity. I also can suggest on how to tune the database server - this may provide a 10x performance boost for free.

Celery is my go-to tool for background processing, to ensure smooth user experience and enable scheduled tasks. It has a lot of caveats, and I've dealt with most of them. Async tasks require a different mindset - I can help you to create a straightforward and bug-free data pipeline.

Redis is often used only as a cache, but it is an insanely valuable tool for fast data storage and atomic operations. I can guide you on how and when to use it's various data structures and teach you to leverage atomicity and avoid race conditions.

I've always deployed everything I've built myself, and I can help you too. The main tools are AWS, Nginx, Gunicorn, Supervisor, and Ubuntu/Linux.

AWS is my favorite cloud provider. I can help you to deploy the whole application, using EC2, S3, RDS, and Route53. I also have experience building reliable cross-service communication via SQS and SNS.
