Case study ยท SaaS

Accelerating feature velocity by 40% through modernization.

A B2B SaaS provider partnered with Velinsa to modernize a legacy platform, introduce automated testing, and regain confidence in their release process.

Stack: Legacy monolith to modular architecture Duration: 9 months Squad: 9 engineers, 1 architect, 1 delivery lead
Client context

Slow releases, growing risk

Years of incremental changes without a clear architectural vision had resulted in brittle code paths, long testing cycles, and frequent production incidents.

  • Release cycles of once per quarter with extended code freezes.
  • Limited automated test coverage and heavy reliance on manual QA.
  • Customer-facing incidents leading to delayed deals and churn risk.
Velinsa scope

Architecture, automation, and enablement

  • Introduce domain-driven design and modular boundaries.
  • Expand automated test coverage and CI/CD pipelines.
  • Implement delivery analytics and error budget policies.
  • Coach teams to own the new architecture and practices.
