Organizing teamwork of backend and frontend team
Some extra as a DevOps

The company specializes in computer vision. Wide range of technical and organizational activities, from infrastructure to development processes.

* Dev stack: python, javascript (react), pytorch, django/drf
* Infrastructure: AWS, terraform, docker
* Flutter/Dart/pytorch mobile for mobile application

Some non-standard solutions:
* Custom dataset processing tool: we couldn't use existing BB/segmentation tools. So did it with react + konva for frontend visualization and django for the backend
* Flutter for mobile: better testing support than appium, easier multiplatform (android + ios) development than react-native, also easier to connect to existing native libs/sdk (pytorch mobile in our case)

There are three main branches of my responsibilities here

Technical management - establish and support development processeses (e2e testing automation, CI, review and release processes), architecture design, code review, switching to react and react-native, team building and education, open sourcing some staff here https://github.com/tipsi/

Backend development - we're using django-rest-framework, asyncio, postgresql, rabbitmq and some other fancy things like docker-based microservices. We've switched to 'test everything' approach and this helped us to make quite big migrations, like mysql -> postgresql, python2 -> python3 and helps us with further updates.

Infrastructure support and development - we're relying on aws for our basic infrastructure, initial pre-setup and management with ansible, monitoring with prometheus and grafana, ELK for log collection, gitlab-ce as internal git server and for CI, docker for everything.
There are some tricky things here, like testing in virtualized osx environment or usage of spot-instances.
