About Matthieu

Vous

Je parie que c'est ce que vous vous dites lorsque vous pensez à la prochaine étape :

💡 Vous n'avez pas de spécialiste interne des tests de perf mais vos techs sont débrouillardes et débrouillards. Il leur faut juste une boussole et de l'élan.
✅ Nous concevons ensemble votre stratégie, nous organisons les formations, et je vous suis en pointillé.

💡 Vous voulez détecter les problèmes plus tôt. Votre CI/CD pourrait peut-être porter des tests de performance. Peut-être que vos devs pourraient décharger vos spécialistes...
✅ Je cadre, je conçois, j'exécute, et je fais vivre des transitions du type Shift-left / Continuous Testing.

💡 Vous avez besoin de quelqu'un pour tester, analyser, et améliorer votre software.
✅ Fantastique, je suis hands-on.

Moi

Je suis Ingénieur en (Tests de) Performance Software, dont on peut résumer la carrière à 15 ans de "c'est lent" en fronçant les sourcils.

Je suis un spécialiste qui s'éclate sur les software sensibles à la milliseconde et sur les défis posés par le test en continu.
Que ce soit en optimisant une plateforme de lutte contre le blanchiment d'argent ou en transformant la culture du test dans une startup, j'apporte un mélange équilibré d'expertise technique, d'empathie, et de confiance mutuelle.
En tant que freelance, je coache des équipes et je conseille des entreprises pour qu'elles bâtissent du software rapide, scalable, efficient, et résilients.

Quand je ne traque pas des problèmes de temps de réponse, vous me trouverez probablement à me promener dans les Alpes.
