About this Gig
Enterprise Technical Documentation, Runbooks & System Specs
Outdated docs and missing runbooks lead to costly downtime. As a senior database architect, I translate complex infrastructure, schemas, and workflows into audit-ready, developer-friendly documentation.
What I Create:
- Migration Runbooks: Step-by-step cutover checklists, staging steps, rollback protocols, and validation scripts.
- Architecture Diagrams: System flowcharts and topologies (Mermaid.js, Draw.io).
- Data Dictionaries: Complete schema mappings, column types, constraints, and relationships.
- API Specs & SOPs: Structured REST endpoint docs, security rules, and disaster recovery plans.
Deliverable Formats:
- Markdown (.md) for GitHub, Notion, or Confluence
- Print-Ready PDFs
- Source diagram files (Visio / Draw.io)
Packages:
- Basic: Single SOP, technical spec, or 1 architecture diagram.
- Standard: Multi-step migration runbook + 2 system diagrams.
- Premium: Complete enterprise documentation suite & data dictionary.

FAQ
What formats do you deliver the technical documentation in?
I provide clean, version-controlled Markdown files (.md), standard PDF export, and raw vector/diagram source files (Draw.io or Visio) so your team can easily update them in GitHub, Notion, or Confluence.
Can you write runbooks for complex cloud or database migrations?
Yes. I specialize in step-by-step cutover runbooks, including pre-migration health checks, staging steps, rollback strategies, and post-migration validation procedures.
Do you require direct system access to write the documentation?
Not necessarily. I can work from architecture briefs, database schemas, codebases, or screen-share walkthrough sessions. If direct read-only access is helpful, it can be provided securely.
