You will get a normalized PostgreSQL or MongoDB database design and optimization
Project details
You will get a clean, normalized database design or optimization that makes your application faster, more reliable, and easier to scale.
Poorly designed databases cause slow queries, data inconsistencies, and expensive rewrites later. I design schemas that are built right from the start — or fix existing ones that are causing problems.
My recent work includes designing a 15+ table PostgreSQL schema for a multi-tenant SaaS platform and improving query performance by 40% through strategic indexing on a production system with real users.
Every schema I deliver is normalized, indexed intelligently, and documented so your team can maintain it confidently.
What makes my work different:
• I explain every design decision (not just deliver SQL files)
• I include migration scripts (Alembic, Knex, or raw SQL)
• I test query performance before and after optimization
• I think about your data at scale, not just today
Whether you need a fresh schema for a new project or optimization of an existing slow database — I will deliver clean, documented, production-ready database architecture.

Background: B.Sc. Biochemistry, with a Software Engineering certification from Holberton School. My analytical foundation combined with hands-on engineering training shapes how I approach problem-solving — methodical, detail-oriented, and focused on getting things right.
My code samples and live project demos are available in my Portfolio section below.
Let's build something reliable.
Steps for completing your project
After purchasing the project, send requirements so Anthony can start the project.
Delivery time starts when Anthony receives requirements from you.
Anthony works on your project following the steps below.
Revisions may occur after the delivery date.
Schema Review & Planning
I review your requirements or existing schema, identify issues, and propose the optimal data model before writing any code.
Design & Implementation
I build normalized schemas, relationships, indexes, and migration scripts according to the agreed design with progress updates.
