The right reinforcement at the right time
More capacity is not enough when nobody owns the outcome.
Useful reinforcement does more than process tickets. It understands the product, makes trade-offs explicit and owns the quality of what reaches production.
Our team stays deliberately compact. The people who scope the engagement are also the ones who develop, deploy and respond when the situation becomes difficult.
This model fits a deadline-driven launch, a temporary seniority gap, a blocked backlog or a transition after a key person leaves.
Engagement models
Reinforcement matched to the responsibility that is missing.
Delivery team
CUB3 owns a product or complete workstream, from technical scoping to production readiness.
Fractional lead or CTO
We secure architecture decisions, delivery quality and the growth of your internal team.
Continuity and transition
We recover system knowledge, handle urgent issues and prepare a durable handover.
Evidence from real engagements
Assignments where extra capacity unlocked a concrete situation.
Each example states CUB3’s exact role, what was delivered and what can genuinely be demonstrated.
A production-ready ecommerce website in 28 days
Promo.dev had to deliver a white-label ecommerce product without the technical team required to build it. Two CUB3 engineers took ownership from the Figma designs onward.
Defensible outcomeA working ordering journey in 28 days, mobile apps delivered after store approval, and the planned marketing calendar preserved.

Maintaining technical continuity on TRADEMEX
Macq brought in a senior profile who already knew the product to support the teams, deliver targeted developments and handle complex production issues.
Defensible outcomeA smoother transition after a key departure, knowledge transfer and continued support for Macq customers.

Speeding up PMS integrations for an overloaded team
Two internal developers had to absorb a growing hospitality-integration backlog. One CUB3 engineer now handles SOAP and REST connectors as needed.
Defensible outcomeCustomer requests delivered without waiting several months, through a collaboration that continues as needs arise.
Read the detailed caseHow we work
A clear integration process without a sales tunnel.
- 01
Define the responsibility
We clarify the expected outcome, required access, constraints and the person who makes decisions on the client side.
- 02
Integrate the right profiles
One or more senior profiles join your routines, repository and tools without adding another management layer.
- 03
Deliver and make progress visible
Decisions, progress, risks and releases remain understandable to both technical and business teams.
- 04
Transfer or continue
The engagement can continue, scale down or end with explicit documentation and knowledge transfer.
« We especially appreciated their availability and responsiveness, particularly during rush periods or when unexpected issues arose. »

Frequently asked questions
What to know before adding an external team.
How quickly can an engagement start?
After a qualification call and scope validation, we confirm the real availability of the relevant profiles. We do not promise a standard start date while access or ownership is still unclear.
Do you work with an existing internal team?
Yes. We can join an existing product team, work alongside a CTO or own an autonomous scope with clearly defined interfaces.
Is this recruitment or a service engagement?
Our primary model is professional services. In some cases, an engagement may lead to an agreed internal hire, as it did at RoboDK.
Can you contribute only a few days per month?
Yes for technical leadership, architecture, production reviews or focused support. A delivery scope usually requires more continuity.
