We unlock the value trapped in your legacy systems through surgical modernization. No full rewrites, no halting daily operations, and eliminating the risk of a "Big Bang" project.
The Problem
Keeping obsolete software isn't savings — it's a silent tax on your company's ability to innovate.
Maintenance vs. Innovation
80% of your IT budget and your team's time is consumed "keeping the lights on" — patching servers and fighting fires — leaving no oxygen for developing new business capabilities.
Direct consequences
The Time-to-Market Bottleneck
Marketing or Sales need an urgent new feature. IT responds it will take 6 months because the core monolith is so fragile that any change risks taking down the entire production system.
Code nobody wants to touch
It's impossible to attract or retain top-tier engineers when your tech stack is 15 years old. System knowledge rests dangerously on one or two key people.
Our Philosophy
The main reason companies fear modernization is the panic of a slow, messy process and the belief that "everything has to be redone from scratch". We don't do that.
We don't rewrite your system overnight. We decouple critical functionalities one by one (e.g., the payments module), build them as modern microservices, and redirect traffic. The user never notices the transition.
Sometimes the code is fine, but the infrastructure is the problem. We containerize your current application (Lift & Shift) to bring it to Kubernetes, gaining stability before touching a single line of business logic.
For months, your legacy system and your new Cloud-Native architecture coexist. We shut down the old system gradually, safely, auditably, and without friction. Zero stress for your team.
Technical Approaches
There's no one-size-fits-all solution. We choose the approach based on your code's actual state, time constraints, and risk tolerance.
We clean and optimize your existing codebase. We eliminate deep technical debt, update obsolete frameworks, and improve automated test coverage to restore your application's maintainability.
We break apart your monolith. We separate the monolithic logic into independent, scalable services (Spring Boot, Node.js, Go) communicated via APIs or events (Kafka), enabling isolated deployments.
When the legacy code is beyond saving and the cost of maintaining it exceeds rebuilding it, we design and build a completely new application, cloud-native from day zero, to the highest industry standards.
Business Case
What does operations look like before and after Andes Digital?
Technologies
We master the full stack — from runtime to the data layer and the cloud.
Frequently asked questions
Modernizing means moving a legacy application to a more maintainable, scalable and secure architecture. The most common strategies are rehost (move as-is), replatform (adjustments to leverage cloud or containers) and refactor (redesign the code). We choose the right combination based on the value, risk and urgency of each system.
When the system holds the business back: rising maintenance costs, difficulty hiring people to support it, security risks, or the inability to add features. If the immediate priority is only portability, sometimes containerizing is enough before a larger refactor.
We scope after assessing the portfolio and each application's dependencies. We work in iterations to deliver value early; first production results usually appear between 8 and 16 weeks. We start with a free initial consultation. Real-world case: LatamWin — migration to AWS.
We move incrementally, using patterns like Strangler Fig that coexist with the current system, automated testing and reversible deployments. The migration happens in parts, without a big-bang cutover, and always with a rollback plan for any surprise.
Let's talk about your current architecture and how to modernize it, without halting operations or doing a massive rewrite.
