Frequently asked questions

Can you take over an application developed by another provider?

Yes. We start with technical onboarding: access to code and environments, an architecture and operations assessment, risk stabilization, and a maintenance baseline — with or without cooperation from the outgoing provider.

Do you work with undocumented source code?

Yes, it's a frequent scenario. We apply reverse engineering and architecture recovery, and essential documentation is rebuilt as part of the work.

Do you maintain legacy Java or enterprise applications?

Yes. We work with Java and Java EE/Jakarta EE, including older versions, both for maintenance and for gradual modernization of runtimes and frameworks.

Do you recommend rewriting every legacy application?

No. A full rewrite is the highest-risk path and is only justified in specific cases. We usually evaluate stabilization, encapsulation, upgrades, or partial modernization first.

Can you modernize without interrupting operations?

That's the goal of the phased approach: gradual changes, validations, and rollback plans. Absolute zero disruption isn't always possible, but it is minimized and planned with the business.

Can you migrate Oracle Spatial workloads to PostGIS?

Yes, through a process that starts with a compatibility assessment: an inventory of the spatial functionality in use, mapping to PostGIS equivalents, a proof of concept, and benchmarking before committing to a cutover. Feasibility depends on the proprietary functionality in use.

When does an open-source migration make sense?

When the analysis of total cost, dependency, risk, and team capabilities supports it. We don't migrate on principle: some proprietary systems are worth keeping.

Can proprietary and open technologies coexist?

Yes — and it's the norm. We design hybrid architectures where each piece is justified by fit and value, with clean integration between the two.

Do you work with our internal engineering team?

Yes, in co-delivery models: joint delivery, mentoring, and knowledge transfer. The goal is to make your team stronger, not dependent.

Do you provide architecture assessments before implementation?

Yes, and we recommend it for complex initiatives: a bounded assessment reduces the risk of the big decisions that follow.

Can you rescue a delayed or unstable project?

Yes. We start with an honest diagnostic of the real state, stabilize what's critical, and propose a recovery plan with explicit decisions.

How do you estimate a project?

Discovery first: understanding scope, risks, and constraints before committing to numbers. Estimates come with explicit assumptions and honest ranges.

Does the AI assistant provide a binding quotation?

No. The assistant generates a preliminary assessment and a suggested roadmap that our team reviews. Prices and timelines are always agreed with people.

Can you build a proof of concept before a larger AI investment?

Yes — it's our preferred route: a prototype on a bounded set of real data that validates quality and feasibility before scaling.

How do you handle security and confidentiality?

Least-privilege access, secure credential management, controlled environments, and secure development practices. Your project information is not shared with third parties.

Do you sign NDAs?

Yes — we sign NDAs before receiving sensitive information whenever you require it.

Do you support multilingual and multi-country platforms?

Yes: real internationalization (not automatic translation), regional formats, time zones, and multi-region deployments when justified.

What happens after deployment?

Continuity: monitoring, support, maintenance, and evolution. Deployment is the start of operations, not the end of the relationship.
