Développement Web & SaaS

Our philosophy

Information is best revealed in layers

We don't arrive with 200 pages of specs under our arm. We break it down, validate, and move forward together — at your pace, without overwhelming you.

Listen first

We don't sprint before understanding your business, users and constraints. The best products come from genuinely listening.

Slice, don't overwhelm

No monolithic delivery. Each piece of information is presented in the right context, at the right time, in the right form.

Show, don't describe

A prototype is worth a thousand words. We show you what we're building before continuing. You validate, we move forward — no surprises.

Iterate with you

10 small validations rather than one big surprise delivery. The product grows with your feedback, sprint after sprint.

Hand over, don't hold on

At delivery, everything belongs to you. Code, documentation, access. We train your team for complete autonomy — no dependency.

Why a methodology?

A project without structure is a project that drifts. Blown deadlines, expanding scope, production bugs, frustrated client. Our 6-phase process eliminates these risks by imposing clear validation checkpoints at each stage — you stay in control, we deliver.

Each phase produces concrete, validated deliverables
No code written without signed specifications
Automated tests before every production deployment
Complete documentation handed over at delivery

Our methodology in detail

Each phase has precise inputs, outputs and acceptance criteria.

Scoping

Phase 0 — Scoping & Discovery

1 – 3 days

Before writing a line of code, we need to understand your business, users and constraints. This foundational phase prevents costly misunderstandings.

Inputs

Client brief (idea, context, indicative budget)
Existing data / systems in place
Regulatory constraints (GDPR, LPD…)

Deliverables

Signed scoping document
User personas (1 – 3 profiles)
V1 scope defined and frozen
Budget & preliminary schedule validated

Acceptance criterion: scoping document signed by both parties before moving to the next phase.

Analysis

Phase 1 — Analysis & Specifications

3 – 10 days

We translate your vision into precise technical requirements. Each feature is described as user stories with acceptance criteria — nothing is left to interpretation.

Inputs

Scoping document (Phase 0)
Interviews with target users
Competitor benchmarks

Deliverables

Functional specification document
Prioritised user stories (MoSCoW)
Risk matrix
Documented technology choice

Acceptance criterion: validated and prioritised backlog, no ambiguous stories.

Design

Phase 2 — Design & Architecture

5 – 15 days

Technical architecture, data model, UI/UX mockups. You visualise the final product before a single file is created. Feedback at this stage costs 10× less than in production.

Inputs

Validated spec document (Phase 1)
Hosting & scalability constraints
Brand guide / graphic charter

Deliverables

Architecture diagram (C4 diagram)
Data model (ERD)
Figma mockups (wireframes + hi-fi)
Validated navigable prototype
Test plan (types, target coverage)

Acceptance criterion: Figma prototype approved, architecture validated by the technical team.

Development

Phase 3 — Development & Sprints

Variable (2-week sprints)

Development takes place in 2-week agile sprints. At the end of each sprint, you receive a demo of what has been built. You can see, test, comment — and steer the priorities of the next sprint.

Inputs

Architecture & mockups (Phase 2)
Prioritised backlog
Configured dev environment

Deliverables (per sprint)

Delivered and tested features
Reviewed and merged code on develop
Unit & integration tests (cov. ≥ 80%)
Sprint report + client demo

Git Flow (feature / develop / main)

TDD / tests automatisés

Code review systématique

CI/CD GitHub Actions

Acceptance criterion: all sprint stories pass their acceptance criteria, no blocking bugs.

Launch

Phase 4 — Launch & Go-Live

2 – 5 days

Go-live is not a gamble — it's a procedure. Deployment checklist, data migration, load tests, rollback plan. You launch with confidence.

Inputs

Application validated in staging
User acceptance tests (UAT) passed
Production infrastructure ready

Deliverables

Application deployed to production
SSL certificates, DNS, backups configured
Monitoring & alerts active (Uptime Robot / Sentry)
Signed production deployment report

Acceptance criterion: green smoke tests in production, monitoring operational, client signs off the acceptance document.

Maintenance

Phase 5 — Maintenance & Evolution

Ongoing (defined SLA)

A living product evolves. We offer maintenance contracts with SLA adapted to your criticality: bug fixes, security updates and iterative feature additions.

Corrective maintenance

Bug fixes (P1: < 4h)
Security updates
Continuous supervision

Evolutive maintenance

New features (mini-sprints)
Performance optimisations
Third-party integrations (API, payment…)

Available contracts: 5h/month, 10h/month, or on request — monthly commitment, cancellable at any time.

Documentation

Phase 6 — Complete Documentation

Delivered with each phase

Documentation is not an afterthought — it is produced throughout the project. At final delivery, you have a complete dossier to evolve or hand over the project internally or to another provider.
