Software Developer Skills
1. Python
Python is a high-level, interpreted language prized for clarity and breadth. It stretches from web backends to data work, AI, scripting, and automation.
Why It's Important
It speeds up prototyping, has batteries-included libraries, and boasts a huge community. You get things done quickly without drowning in boilerplate.
How to Improve Python Skills
Steady practice wins. Tighten fundamentals, then layer on advanced patterns and real projects.
Nail the core: Syntax, data structures, functions, modules, and common algorithms.
Code daily: Small scripts, katas, and challenges to build fluency.
Go deeper: Comprehensions, decorators, generators, context managers.
Ship real things: Build microservices, CLIs, or contribute to open source.
Write clean Python: Follow PEP 8 style and meaningful naming.
Learn the ecosystem: NumPy, Pandas, FastAPI, Django, Flask, PyTest.
Test and debug: Unit tests with unittest or pytest; step through with pdb or your IDE.
Read code: Study well-structured repositories and seasoned contributors’ patterns.
Explore, code, refactor, repeat. The cycle compounds.

6. Docker
Docker packages applications and dependencies into portable containers so software runs the same on every machine.
Why It's Important
It slashes “works on my machine” mysteries, speeds delivery pipelines, and makes local development mirror production.
How to Improve Docker Skills
Smaller images, reproducible builds, and secure defaults are the name of the game.
Write tight Dockerfiles: Multi-stage builds, fewer layers, smart caching, minimal base images.
Use Compose: Orchestrate multi-container dev environments with simple YAML.
Resource controls: Set CPU, memory, and I/O limits to prevent noisy neighbors.
Security basics: Non-root users, least privilege, image scanning, and secret management.
Registry hygiene: Tagging, immutability, and pruning old images.
Observability: Centralized logs, metrics, and health checks.
