The core decision

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

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.

Fit

Who this service helps

  • Founders designing the data model for a SaaS, marketplace, CRM, POS, or operations platform.
  • Teams whose current schema is slowing feature delivery or reporting.
  • Businesses planning a legacy migration or database cleanup.
  • Engineering teams needing review of tenancy, permissions, audit trails, or data integrity.

Scope

Scope agreed around the product

  • Domain modeling and relational schema design
  • Tenant-aware data models for SaaS and multi-branch operations
  • Indexes, query review, and reporting data design
  • Data migration, mapping, reconciliation, and validation planning
  • Audit trails, status models, permissions, and record ownership
  • Documentation, data dictionary, and handover

Deliverables

What the engagement can deliver

  1. A database design blueprint or ERD tied to business workflows
  2. Schema, relationship, constraint, and indexing recommendations
  3. Migration and reconciliation plan for legacy data where needed
  4. Reporting and analytics data model recommendations
  5. Data dictionary and implementation backlog

Platform & Integration Review

Focused assessment

A prioritized decision plan for your existing platform.

How we work
Agree the questions and access, review the platform, then walk through the findings and next decisions.
What you provide
The current architecture, known incidents, the list of integrations, and appropriate access to documentation or code.
Engagement boundaries
One platform. Penetration testing, code rewrites and migration execution are scoped separately.

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.
