How It Works

A rigorous engineering methodology, zero black-box — each phase delivers concrete outputs you can audit.

01

Discovery & Audit

1 to 3 days

Before writing a single line of code, I audit the existing system and frame the real problem. If you have an existing project, I review the codebase, infrastructure, and security risks. If it's a greenfield build, I map out the business and technical constraints upfront to eliminate costly pivots later.

Livrables clés / Key deliverables

  • Technical audit report: tech debt, risks, and blockers identified
  • Business flow mapping with performance and scalability constraints
  • Formalized delivery scope (in-scope, out-of-scope, assumptions)
  • Phased cost and timeline estimate with autonomous milestones
02

Architecture & Proof of Concept

3 to 7 days

I design the target architecture before building anything. Technology choices are justified through ADRs (Architecture Decision Records). A validated POC covering the highest-risk technical unknowns is delivered before the build starts — to eliminate uncertainty, not defer it.

Livrables clés / Key deliverables

  • Architecture diagrams (C4 model: context, containers, components, deployment)
  • ADRs documenting every structural decision (stack, patterns, security model)
  • Database schema with constraints, indexes, and migration strategy
  • Functional POC validating the riskiest technical hypotheses
03

Iterative Build & CI/CD

2-week sprints

Development runs in short sprints. From sprint 1, a CI/CD pipeline is live: every commit is automatically tested, linted, and deployed to staging. You have real-time access to the Git repository and staging environment — zero tunnel effect, zero surprises.

Livrables clés / Key deliverables

  • CI/CD pipeline live from sprint 1 (automated tests, lint, auto-deployment)
  • Strictly typed, reviewed codebase with unit and integration test coverage
  • End-of-sprint demo with functional sign-off in the staging environment
  • Structured changelog and updated technical documentation at each release
04

Hardening, Deployment & Handover

1 to 2 weeks

Before going live, I run a full hardening pass: OWASP audit, load testing, permissions and secrets review. The production deployment is fully instrumented (monitoring, alerting, rollback). Your team receives the training and documentation to operate the system independently.

Livrables clés / Key deliverables

  • Pre-prod security audit report: OWASP Top 10, HTTP headers, dependencies
  • Load test results and SLO validation (response time, availability targets)
  • Monitoring & alerting configured (Grafana, Sentry or equivalent) with runbook
  • Full operational documentation + knowledge-transfer session
