System modernization

Custom software

Leave behind the spreadsheets and systems that can't keep up.

We replace runaway spreadsheets, old programs and tools that have outgrown their purpose with a modern, secure and easy-to-maintain system. Without stopping your operation and without losing a single piece of data.

Before and after

The difference shows from day one

This is what changes when you leave the patches behind and move to a custom-built system.

Before

  • Dozens of scattered spreadsheets with no version control
  • Duplicated data that never quite adds up
  • Old programs only one person understands
  • Manual, slow and error-prone processes
  • Fear of touching anything in case it breaks
  • Impossible to know what's happening in real time

After

  • A single source of truth for the whole company
  • Consistent, up-to-date and reliable data
  • A modern, documented and maintainable system
  • Automated processes that save hours
  • Safe changes thanks to backups and tests
  • Dashboards with information at a glance

How we work

From legacy to a modern system, step by step

A clear migration plan that protects your operation and your data at all times.

  1. Audit of the current system

    We analyze what you have, what works, what doesn't and which data and processes are critical.

  2. Migration plan

    We define where to start, in what order and how to coexist with the old system safely.

  3. Custom rebuild

    We rebuild the system with modern technology, improving processes along the way.

  4. Data migration

    We move your information with validations and checks so nothing is lost.

  5. Coexistence and testing

    The new and the old run in parallel until we confirm everything adds up.

  6. Legacy shutdown

    Once the new system is validated, we retire the old one in full safety.

Modernize without slowing down your business

We know how scary it is to touch the system the whole company depends on. That's why we don't do risky "big bangs": we migrate gradually, running alongside the old system until the new one works with guarantees.

First we understand what your current system does (even that spreadsheet that runs half the company) and then we rebuild it better, without losing what already works and fixing what doesn't.

What it solves

What it solves

  1. No more single-person dependency

    When everything lives in someone's head or spreadsheet, your company is at risk. We document it and make it maintainable.

  2. End of manual errors

    We automate the repetitive and add validations so data goes in right the first time.

  3. Performance restored

    That slow system that crashes daily becomes fast and stable.

  4. Future-proof

    Current technology with support and community, ready to keep growing for years.

Technology

From obsolete to maintainable

We migrate from almost any source to a modern, standard, future-proof stack. No strings attached.

We migrate from

  • Excel / CSV
  • Access
  • FileMaker
  • Legacy software
  • Old databases

We migrate to

  • Laravel
  • Node.js
  • Vue / React
  • PostgreSQL
  • MySQL

Infrastructure

  • Docker
  • AWS
  • Automatic backups
  • CI/CD
  • Monitoring

Gradual migration, no scares

Migrating doesn't have to mean shutting down the company for a weekend and praying. We work in phases: we run alongside the old system, migrate in parts and validate each step before switching off the old one.

We make backups, tests and comparisons to ensure every piece of data lands correctly. When the new system proves it works, we retire the old one with peace of mind.

Common cases

  • Companies that run everything on Excel
  • Old custom programs with no maintenance
  • Legacy software no one knows how to touch anymore
  • Access, FileMaker and obsolete databases
  • Slow systems that can't handle growth

Frequently asked questions

What companies usually ask us before modernizing.

  • No. We migrate with validations and checks, and keep backups of the old system. We compare that every piece of data lands correctly before signing anything off.
