Developer Skills
1. Python
Python is a high-level, interpreted language prized for clarity and breadth. From APIs to data pipelines to machine learning, it slips into almost any stack without drama.
Why It's Important
Python’s standard library, thriving ecosystem, and gentle learning curve let you move fast, automate the boring bits, and prototype ideas that actually make it to production.
How to Improve Python Skills
Write code daily: short scripts, tiny services, small experiments—reps matter more than perfection.
Think Pythonic: embrace list/dict comprehensions, slicing, context managers, and idioms that read like prose.
Adopt type hints: add annotations and run static checks to catch bugs early and document intent.
Level up your tooling: virtual environments, dependency managers, formatters (like Black), linters (like Ruff), and test runners.
Learn async: use asyncio for high-concurrency workloads; understand event loops, tasks, and backpressure.
Master core libraries: pathlib, logging, concurrent.futures, functools, dataclasses—work smarter, not harder.
Read PEPs that matter: style (PEP 8), typing (PEP 484 and friends), packaging norms—guides that shape good habits.
Contribute or dissect code: open source or well-architected repos deepen intuition for structure, testing, and naming.

5. SQL
SQL is the language of relational data. Query, shape, and safeguard information with precision.
Why It's Important
Data sits at the center of most products. SQL lets you slice it cleanly, tune queries, and keep systems fast and correct.
How to Improve SQL Skills
Solidify the basics: SELECT, JOIN, GROUP BY, HAVING, and filtering that avoids surprises.
Go advanced: window functions, CTEs, pivoting, recursive queries—power tools for complex reporting.
Read query plans: understand indexes, scans, sorts, and how the optimizer thinks.
Design schemas: normalization vs denormalization, constraints, and careful use of surrogate keys.
Index wisely: composite keys, covering indexes, and selective predicates—speed with balance.
Mind transactions: isolation levels, locks, deadlock avoidance, and idempotent writes.
Practice relentlessly: real datasets, real questions, and refactors that remove hidden N+1s.
Know your engine: Postgres, MySQL, SQL Server all have quirks; learn the dialect you ship.

6. Docker
Docker packages apps and their dependencies into containers. Same bits, same behavior, everywhere they run.
Why It's Important
Consistent environments shrink “works on my machine” to zero, speeding delivery and reducing drift between dev, staging, and prod.
How to Improve Docker Skills
Write tight Dockerfiles: small bases, multi-stage builds, pinned versions, and minimal layers.
Prefer least privilege: non-root users, read-only filesystems, and explicit capabilities.
Compose services: define multi-container apps clearly—networks, volumes, healthchecks.
Cache smartly: order instructions to hit cache, prune aggressively, and measure build times.
Scan images: catch vulnerabilities early; rebuild promptly when bases update.
Use BuildKit: parallel stages, secrets, and improved caching for faster, safer builds.
Log and observe: consistent stdout/stderr, structured logs, and metrics from day one.
Mind storage: volumes for state, bind mounts for dev, and clear backup/restore paths.
