Hello,
I am a senior Python & ETL developer and have been working with these stacks for over 7 years.
Please check my past SAAS work; shimmercat.com. As you can know, this SAAS project was built by Python, Django, Elasticsearch, Logstash, Beats, PostgreSQL, Grafana, Docker, Redis, and so on.
So I would like to help you with my experiences and skills.
Best regards,
Maksym
