Database Design Services | Ronhy Raktos - Fullstack Web Developer Portfolio

Database Design Services that structure efficient and scalable databases.

I specialize in designing normalized and optimized database schemas using MySQL and PostgreSQL.

Structuring efficient databases, writing clean queries, and ensuring performance for scalable applications. Expert database design with proper normalization, indexing strategies, and query optimization.

"Great applications are built on great databases - I design schemas that scale."

Technologies

Database Tech Stack

Core Database Design

Building robust and scalable database architectures:

Schema Design – Entity-Relationship (ER) modeling with proper normalization (1NF to 3NF)
MySQL & PostgreSQL – Expert database design for both relational systems
Relationships – One-to-One, One-to-Many, Many-to-Many relationships design
Data Types & Constraints – Optimal data type selection and integrity constraints

Performance & Optimization

Ensuring high-performance database operations:

Indexing Strategy – B-tree, Hash, Full-text indexes for query acceleration
Query Optimization – Writing efficient SQL queries with execution plan analysis
Partitioning & Sharding – Horizontal scaling strategies for large datasets
Backup & Recovery – Automated backup strategies and disaster recovery planning

Why Proper Database Design?

Strong database foundations enable scalable applications:

Data Integrity – Constraints and relationships ensure data accuracy
Query Performance – Well-designed databases execute queries in milliseconds
Scalability – Proper design supports growth from thousands to billions of records
Maintainability – Clean schema design reduces bugs and makes maintenance easier

Development Flow

Database Design Process

01

Requirements Analysis

Gather business requirements and understand data flow, identify entities and their attributes, analyze relationships between entities, determine access patterns and query requirements, and document business rules and constraints.

02

ER Modeling & Schema Design

Create Entity-Relationship diagrams, design normalized table structures, define primary and foreign keys, establish data types and constraints, and plan for scalability and future growth.

03

Optimization & Indexing

Design optimal indexing strategies, write efficient SQL queries, analyze query execution plans, implement partitioning for large tables, and plan caching strategies for frequently accessed data.

04

Implementation & Documentation

Create database migration scripts, implement triggers and stored procedures, setup backup and recovery procedures, provide comprehensive documentation, and ensure data security with proper access controls.
