Areas of expertise

Four pillars, one standard: execution excellence

A sharply defined service catalogue covering the entire lifecycle of a modern information system — from architecture to secure production rollout.

01

Custom Architecture & Development

Distributed systems, microservices and modular monoliths built to last.

  • Microservices architectures & modular monoliths
  • High-velocity REST / GraphQL APIs, SaaS & legacy integrations
  • Web & mobile applications — Next.js, React, Astro, Node.js/TypeScript, Go, Rust
  • Distributed databases — PostgreSQL, Redis, ClickHouse, Vector DBs
TypeScriptGoRustGraphQLPostgreSQL
02

Cloud Engineering, Edge & DevSecOps

Migration, modernization and operation of Zero-Trust infrastructure.

  • Cloud migration & modernization — Cloudflare, AWS, GCP, Azure
  • Infrastructure as Code — Terraform, OpenTofu, Pulumi
  • Automated CI/CD, Docker & Kubernetes containerization
  • Edge compute & Core Web Vitals optimization, global latency

Reference architecture

Built for the Edge, designed for scale

Our target architectures place business logic as close as possible to users: Edge workers, distributed databases and event-driven pipelines, orchestrated through Infrastructure as Code.

infrastructure.ts
const edge = new Worker("api", {
  region: "eu",
  compatibilityDate: "2026-09-01",
  kv: ["CACHE"],
  routes: ["foubetm.com/*"],

Engagement methodology

Non-negotiable engineering discipline

Every deliverable follows the same quality protocol, regardless of engagement size.

TDD

Systematic Test-Driven Development: the test suite precedes implementation.

Automated CI/CD

Reproducible build, test and deploy pipelines from the first commit.

OpenAPI / Swagger

Contractual API documentation generated and versioned with the code.

99.99% SLA

Contractual availability targets with monitoring and alerting.

Agile / Scrum

Short cadences, iterative demos and full progress transparency.

Docs as Code

Architecture Decision Records and runbooks versioned in the repo.

From framing to production

A clear path. No black box.

Every engagement progresses through explicit decisions, measurable proof and deployable increments. You always know what is delivered, why, and to what quality standard.

  1. 01

    Technical framing

    Goals, constraints, risks and success metrics aligned before implementation begins.

  2. 02

    Architecture & proof

    Target architecture, ADRs and a measurable prototype to de-risk key decisions.

  3. 03

    Industrialized delivery

    Short cycles, TDD, CI/CD and regular demos with complete visibility.

  4. 04

    Production rollout

    Progressive deployment, observability, runbooks and complete knowledge transfer.

Frequently asked questions

What CIOs and CTOs usually ask us

Do you work on a fixed-price or time & materials basis?

Both. Defined-scope missions (audits, targeted reworks, migrations) are contracted on a fixed-price basis with frozen deliverables. Team augmentation is billed time & materials, with a senior engineer embedded in your squad.

Do you only work in Paris?

The office is in Paris 11th, but engagements run remote-first across Europe with regular sync points. On-site work in Paris and the Île-de-France region is possible.

How do you guarantee the 99.99% SLA?

Through architecture (multi-PoP redundancy, graceful degradation), observability (metrics, alerting, SLOs) and incident runbooks delivered with the system. The SLA is contractualized in the statement of work.

Who owns the code and infrastructure?

You do. Repositories, pipelines, IaC and documentation are transferred into your organizations from the first sprint. No proprietary lock-in is created.

Can you take over an existing project in difficulty?

Yes — that is exactly what our Audit & Rework offering covers: code and architecture diagnostics, a prioritized remediation plan, then progressive execution without a big bang.

What is the typical lead time?

A first technical call within 48 business hours, framing in a few days, and mission start generally within 2–3 weeks depending on availability.
