B2B SaaS product · Short engagement

Fullstack SaaS platform

Recovered a SaaS product foundation to clarify architecture, make front/backend exchanges reliable and accelerate delivery.

  • React
  • Next.js
  • TypeScript
  • Node.js
  • NestJS
  • PostgreSQL
  • Prisma

Problem

The product needed to keep evolving, but screens, API contracts and access rules no longer gave the team enough visibility.

Solution

Recovered key journeys, clarified front/backend responsibilities, tightened typing, better scoped auth and split the technical backlog into verifiable steps.

Outcomes

  • Changes split into smaller, safer delivery batches.
  • API contracts and access rules became readable across layers.
  • Technical backlog prioritized without blocking the product roadmap.
  • Foundation became easier for the team to own.

Highlights

  • Front/back framing.
  • API, auth and data.
  • Product-minded delivery.

This anonymized case study reflects a common senior reinforcement mission: understand the business logic, clarify fragile technical areas and ship without interrupting the team. The work focused on making decisions visible so the product could keep moving after the engagement.
