Model the business before creating tables
We identify the core entities, lifecycle states, ownership rules, and reporting needs. That keeps the schema connected to business behavior rather than mirroring a screen-by-screen prototype.

Database Development & Design
Design the database layer behind a product so it protects the business rules, supports reporting, handles growth, and avoids costly migration problems later.
The database is where product decisions become permanent
The database is where product decisions become permanent
A database design defines how the business understands customers, orders, tenants, payments, workflows, permissions, and history. Poor modeling creates reporting gaps, duplicate records, slow features, and risky migrations. I help design schemas, relationships, constraints, indexes, data flows, and migration plans around the product and operational reality.
In depth
Design for tenancy, permissions, and auditability
SaaS and operational platforms need clear tenant scope, role boundaries, record ownership, and change history. The database model should help enforce those rules rather than relying only on application convention.
In depth
Plan performance and reporting from the start
Indexes, query shape, denormalization, reporting tables, and background processing are chosen around expected access patterns. The goal is to support product screens and business reporting without turning every dashboard into a slow custom query.
In depth
Migrate and reconcile legacy data carefully
Legacy imports are rarely clean copies. Field meanings, duplicates, missing references, historical states, and source-system mistakes must be reconciled with business rules before the new system can be trusted.
In depth
Document ownership and change rules
The deliverable can include ERDs, migration plans, validation rules, data dictionaries, and developer handover notes so the database remains understandable as the product evolves.

Explore all services →What does a database development & design engagement start with?
It starts with the product goal, current system, users, data, and constraints. The first step is to decide what should be built, what should be reused, and what risks must be removed before implementation.
Can you work with an existing team or codebase?
Yes. The engagement can review the existing architecture, codebase, backlog, and delivery process, then define a practical plan that your team can execute or that I can help deliver directly.
Do you only advise, or can you build the system too?
Both are possible. Some engagements produce an architecture and delivery plan for your team. Others include implementation, technical leadership, review, and handover. The build scope is agreed separately from the assessment.
How do you avoid overbuilding?
The scope is tied to the business workflow, expected users, operational constraints, and evidence from existing projects. Features, infrastructure, and integrations are prioritized by what the product must do reliably now and what can safely wait.
Can this be handled remotely for international clients?
Yes. Discovery, architecture review, implementation planning, and delivery can be run remotely with agreed access, milestones, communication rhythm, and documentation standards.
