estructurIA

estructurIA helps contractors, civil engineers, architects, and construction professionals replace error-prone generic spreadsheets with a centralized system for creating and managing formal project budgets.

The product is built as a modular monolith with Next.js App Router, tRPC, and Zod. Business rules and monetary calculations run in server-side domain services before Drizzle ORM persists the data in PostgreSQL, keeping the web interface, Excel exports, and PDF reports consistent.

Implemented capabilities include secure authentication, project CRUD, versioned budgets, hierarchical categories and concepts, a reusable master catalog with user favorites, budget templates, controlled autosave, persistent ordering, editable Excel exports with live formulas, and PDF export history in private cloud storage.

Supabase provides authentication, PostgreSQL, private file storage, and Row Level Security for per-user data isolation. Excel exports are sanitized against formula injection, privileged service credentials remain server-only, and Sentry supports error monitoring.

As founder and product engineer, Alexis defined the product roadmap and architecture and implemented advanced workflows including templates, catalog favorites, ordering controls, optimistic autosave, unit tests with Vitest, and end-to-end stabilization with Playwright. The product remains in active MVP development and does not yet have verified usage or business metrics.
