Cost optimizations
DB/code optimizations (last one i remember was like 10x speedup on core parts of the application), implementing "hacky" caching techniques
Hiring & onboarding
Alleviating issues with unit tests requiring db
*Relatively painless* remediation of fundamental design flaws
As Head of Engineering i was busy with:
- Features/bugfixes/refactoring/reviews
- Counseling executive team & different devs departments
- Long/short-term planning
- Workflows development & transformations
- Tech stack maintenance (security updates, performance improvements, tech migrations)
- Infrastructure changes
- Managing tech debt
- Cost optimizations
- Major third-party integrations (posthog/google/bing analytics, Framer, etc.)

As Middle Python Software Engineer i did:
- Features/bugfixes/refactoring/reviews
- Technical troubleshooting
- DB/code optimizations, caching techniques
- Hiring & onboarding
- Unit testing (increasing coverage, development test isolation techniques, optimizations, observability)
- Application errors monitoring
- CI/CD updates
- External services development
- Relatively painless remediation of fundamental design flaws

As Middle Python Developer i was assigned to do:
- Features/bugfixes/refactoring/reviews
- Cloud services development (AWS)
- Third party integrations (airlines, payment gateways, etc.)
- Core E-commerce-like modules development and support
- Infrastructure designing
- Microservices migration (strangler pattern)

As Junior Python Developer i attempted (mostly successfully):
- Implementing new features/fixing bugs
- Refactoring
- Increasing unit tests coverage (even wrote a routine to write tests by itself, what would you realistically expect when they were only concerned by coverage percentage, not corner cases)
- Contributing to internal projects
- Learning production microservices architecture
In the same way that a bigger fish needs a bigger aquarium, I am eager to leap into a larger professional pond. Specifically cloud development, system design & architecture.
