I'm a Database Management Systems (DBMS) expert. I'll handle any database task — SQL queries, schema design, ER diagrams, normalization, or a full database project — built exactly to your requirements.

WHAT I DO

Design • Conceptual, logical, and physical database design • ER diagrams and ERDs built from plain-English scenarios • ER diagram → relational schema conversion • Relational schema → SQL DDL conversion • Normalization to 1NF, 2NF, 3NF, and BCNF (with the dependency reasoning written out)

SQL • CREATE, INSERT, UPDATE, ALTER, DELETE, and complex SELECT queries • Joins, subqueries, CTEs, window functions, aggregations • Views, indexes, constraints, primary and foreign keys • Functions, triggers, and stored procedures • Data extraction and reporting queries • Query optimization and execution plan tuning

Projects • Complete database projects with a simple front end • Sample data generation and seeding • Full documentation of the design decisions

DATABASES MySQL, PostgreSQL, Oracle, SQL Server, SQLite, MongoDB, Redis.

WHY ME • Every delivery includes documentation mapped to your exact requirements • Flexible budget and scope • I'll walk you through how the solution works, so you can explain it yourself • Quality guaranteed — revisions until it matches the requirement

Don't see your task listed? Message me anyway — if it touches a database, I can almost certainly help. Send the requirements and I'll quote you.
