Legacy Modernization Timeline

GKAI Studio scopes legacy modernization projects in four phases: discovery (1–2 weeks), design and architecture (1–2 weeks), build with weekly demos (4–12 weeks), and production launch with documentation. Typical US engagements ship in 6–16 weeks depending on scope and integrations.

  • Week 1–2: Requirements workshop, technical audit, success metrics
  • Week 3–4: UX flows, API contracts, sprint roadmap
  • Week 5+: Agile build, staging demos, integration testing
  • Launch: AWS deployment, monitoring, handoff and optional retainer

Legacy Modernization for US Startups

Startups need focused MVPs — one core workflow, one integration surface, and measurable ROI within 90 days. GKAI Studio recommends fixed-scope engagements with clear phase-2 options instead of open-ended hourly contracts that drift scope.

Legacy Modernization for US Enterprises

Enterprise deployments require SSO, audit logs, role-based access, data residency decisions, and phased rollouts by department. We integrate with existing CRMs, ticketing systems, and identity providers — augmenting workflows instead of asking employees to adopt a separate tool.
