Independent developer · Web apps & websites
Web apps and websites, delivered fast.
And tested against attacks.
Years of experience with large enterprises, and artificial intelligence put to work for speed and security: Vertigo Dev builds web apps and websites designed for production and tested against attacks before they go live.
01 — Approach
Four strengths, one point of contact
AI is changing how the web gets built. It does not change what makes a project succeed: understanding the need, making the right choices and leaving nothing to chance.
Accelerated delivery
AI handles the repetitive work: code generation, tests, documentation, reviews. I stay in charge of what matters — architecture, trade-offs, quality. The result: shorter lead times, without technical debt swept under the rug.
Security on equal terms
Attackers already use AI to find weaknesses faster. I use the same techniques, but on your side: code analysis, penetration tests with written authorisation, dependency monitoring. The aim: find the weaknesses before go-live, not after an incident.
Field experience
AI does not replace experience. Years of IT services assignments for large enterprises taught me to translate a business need, anticipate growing traffic and take regulatory constraints into account. That perspective brings the result closer to what you expected. Read the background of Vertigo Dev.
Accessibility by design
A website should work for everyone: with a keyboard, with a screen reader, with strong zoom or on a small screen. I design and build following the RGAA and the WCAG at level AA: structured headings, sufficient contrast, clear forms, visible focus. Every project is checked with the keyboard and with audit tools, then reviewed by hand. Only a full audit can then establish a level of conformance.
02 — Security
AI attacks.
AI protects.
Scanning thousands of pages, guessing passwords, spotting a vulnerable dependency: what used to take an attacker days now takes minutes. Waiting for the attack before reacting is no longer an option.
Every Vertigo Dev application goes through a security review run with the same tools attackers use, then validated by an experienced human eye. You receive a clear report: what was tested, what was fixed and what will need watching.
- Static analysis and code review
- Injections, unauthorised access, data leaks
- Security headers, cookies, encryption
- Dependencies and known vulnerabilities
Already have an application? The web security audit applies the same approach, with the written authorisation of its owner.

› access control (IDOR) .......... ok
› vulnerable dependencies ........ 0 critical
› HTTP security headers .......... present
› secrets exposed in the repo .... none

Five ways to work together
One need, one service: each comes with its own process, deliverables and single point of contact.
Custom web application development
A business tool that follows your processes, delivered in short increments and tested at every release.
Business website design
A fast website, bilingual if needed, built to be found and to turn a visit into a contact.
Website redesign
Modernise an existing website without losing its search rankings or its content.
Web security audit
A clear picture of your application’s security, with a prioritised remediation plan.
Maintenance and enhancements
Security updates, fixes and new features, over the long term.
04 — Method
From need to go-live, with no grey areas
- 01
Scoping
Your need, your users, your constraints: everything is laid out from the start, including GDPR, accessibility and search visibility.
- 02
Architecture
Proven technologies, chosen on measurable, documented criteria — never because they are fashionable.
- 03
Test-driven development
Each feature is first described by a test, then built with the help of AI. What is delivered does what was planned.
- 04
Security audit
The application is attacked before it is published — by AI, then by experience. Every effort is made to keep critical weaknesses out of production.
- 05
Go-live and handover
Hosting sized at the right cost, deployment documented step by step: you stay in control of your application.
