1. SQL
SQL (Structured Query Language) is the lingua franca of relational databases—querying, shaping, and governing data so people can actually use it.
Why It's Important
It powers analysis and reporting, unlocks trends hidden in tables, and keeps operations tight. Without reliable SQL, the rest of the tech stack limps.
How to Improve SQL Skills
Go beyond SELECT-star and cruise into performance land:
Use advanced features: window functions, CTEs, pivots/unpivots, conditional aggregates.
Read query plans: understand scans vs. seeks, join strategies, cardinality estimates, and how indexes change everything.
Design for clarity: normalize to reduce anomalies, then denormalize tactically for speed where read-heavy workloads demand it.
Prefer set-based logic: avoid row-by-row cursors; vectorized thinking wins.
Master transactions: ACID fundamentals, isolation levels, optimistic vs. pessimistic concurrency.
Practice with real data: public datasets, production-like samples, messy inputs—make the optimizer work.
Diversify engines: get hands-on with at least two systems (e.g., PostgreSQL and SQL Server or MySQL) to broaden instincts.
Keep iterating. Query, profile, refactor, repeat.

How to Improve Python Skills
Write daily: tiny scripts, quick utilities, and frequent refactors—muscle memory matters.
Adopt modern tooling: virtual environments, dependency managers (e.g., Poetry), structured logging, and task runners.
Lean into data: pandas or polars for frames, SQLAlchemy 2.x for databases, Pydantic for validation.
Ship services: build APIs with FastAPI or Flask; learn async when concurrency makes sense.
Test and type: pytest, coverage, and type hints with mypy—clean code survives longer.
Profile and optimize: timeit, cProfile, memory profiling; vectorize before you micro-optimize.
Read great code: study mature open-source projects to absorb idioms and patterns.
Small wins stack quickly. Automate a chore; then automate five more.
