Where does a software rescue start?

With a short assessment of the codebase, infrastructure and incidents, then stabilization of the most urgent issues before any larger change.

Do you rewrite the system from scratch?

Rarely. The default is incremental modernization that keeps the product running, as with the move toward microservices at TecKnow Solutions.

What results has modernization work produced?

50% fewer production defects at Faculdade Rebouças after CI/CD and safer releases, and deployment time down from days to hours at TecKnow Solutions.

Can you work on a codebase someone else wrote?

Yes. ElevateAB, Faculdade Rebouças and TecKnow Solutions were all existing products with live users.

Software Rescue, Modernization & Scaling

Scale

Stabilization and modernization of live products that have become slow, fragile or hard to change, without stopping the business while the work happens.

At Faculdade Rebouças, CI/CD and safer releases cut production defects by 50%. At TecKnow Solutions, moving legacy systems toward microservices took deployment time from days to hours. At ElevateAB, architecture and performance work kept experiments running in live storefronts without slowing pages.

What it includes

Scope

01
Stabilization first: monitoring, error tracking and the most urgent fixes.
02
Performance work on pages, APIs, queries and background jobs.
03
CI/CD, automated tests and safer release processes.
04
Incremental migration of legacy code, frameworks or infrastructure.
05
Documentation so the team can keep the system healthy.
