I managed a team of +8 designers, driving innovation in UX/UI to create cohesive, user-friendly experiences. My focus was on building scalable design systems, enhancing product usability, and aligning the design strategy with business objectives.

Designing interfaces that make sense • lempire • XXII • Apple

Greetings! 

I am a Senior product designer at lempire and an avid design enthusiast, particularly in the fields of interface and interaction design.

Many entrepreneurs underestimate the tremendous impact of design, in all its forms, and this is a huge mistake. Design has an incredible influence on life, society, and product development, making it the most important aspect. Without design, without interface, without ergonomics, without user analysis, there is nothing but a bad product.

My journey reflects this sentiment, and today I stand alongside lempire to make design a strategic lever to help as many people as possible in their business development through the likes of @lemlist, @lemwarm, @taplio, @tweethunter, and so much more soon...

UI, UX, visual and brand design of all products and brands of the company.

lempire

At lempire, we build tools that help sales teams grow : lemlist for multichannel outreach, lemwarm for email deliverability, lemcal for effortless scheduling.

As CTO, my role is to make sure our tech scales as fast as our ambitions. I focus on:
✅ Keeping our stack lean & efficient—We run on Meteor.js, deploying every day with a monorepo and a trunk-based approach. No unnecessary complexity, just shipping value fast.
✅ Empowering devs—I believe great engineers don’t just write code; they understand the business, solve problems, and challenge ideas. My goal is to foster a culture where developers grow as fast as our products.
✅ Bridging tech & business—A great product is not just well-coded; it drives revenue. I work closely with our product and sales teams to make sure what we build moves the needle.

👨‍💻 Still coding? Yes, sometimes! Because leading by example beats long meetings.
🛠️ Passionate about Lean, AI, and automation—but only when they actually bring value.
🌍 100% remote & async-friendly. We don’t work harder, we work smarter.

Want to chat about tech, scaling teams, or AI? My DMs are open!

I originally joined lempire as a developer, drawn in by my passion for Meteor.js. The framework’s simplicity, real-time capabilities, and full-stack efficiency completely clicked with my vision of how modern apps should be built. What started as a deep technical interest quickly turned into a mission to scale a fast-moving engineering team while keeping our stack lean, powerful, and developer-friendly.

CTO at lemlist - building the best place for devs

👨‍💻 CTO with 20+ years in tech—from C++ in Taiwan to AI agents in France.

CTO focused on building high-performing teams and delivering real business impact through tech.

After starting my career coding in C++ and .NET in Taipei, I spent over a decade managing large-scale projects at Airbus, before diving deep into the startup world.

Today, I lead engineering at lempire, where we build sales tools like lemlist, lemwarm, and lemcal. I joined as a fullstack dev passionate about Meteor.js—and grew into the CTO role by focusing on scale, simplicity, and impact.

✅ Keeping tech aligned with real business goals
✅ Still getting my hands dirty in code when it matters

Whether it’s building teams, launching products, or simplifying complexity, I bring both the mindset of a developer and the vision of a product leader.

Les rôles cachés de la tech : ceux qui font tourner un produit moderne (et qu’on sous-estime encore trop)

On parle beaucoup des développeurs.
Mais dans un produit SaaS qui scale, trois autres familles de rôles sont absolument clés — surtout avec l’arrivée de l’IA.



🔹 La Data : plusieurs métiers, une mission: transformer du bruit en décisions

La “Data” n’est pas un rôle.
C’est un écosystème de compétences :

Data Engineer : construit les pipelines, fiabilise la collecte, optimise la modélisation. Sans eux, les modèles d’IA apprennent n’importe quoi.
Analytics Engineer : structure, nettoie, normalise, pour que les dashboards racontent quelque chose d’utile.
Data Analyst : transforme les questions business en réponses exploitables.
Data Scientist : crée les modèles prédictifs, travaille sur l’IA, la personnalisation, les recommandations.

Avec l’IA, leur importance explose :
un bon Data Scientist ne peut rien faire sans des pipelines propres, et une boîte sans culture Data n’arrivera jamais à tirer le potentiel réel des modèles.

L’IA n’est pas “magique” : elle repose sur un système data solide.

Merci Eliott, Ibrahim Fala, Ahmed Kooli

🔹 SRE / Infra / Sécurité : l’art de garder la plateforme vivante, rapide, et sûre

Ces rôles sont souvent invisibles… jusqu’au jour où ils ne le sont plus.

SRE (Site Reliability Engineering)

Observabilité
Scalabilité
Gestion des incidents
Fiabilisation des services
SLO / SLI / SLA

Leur obsession : réduire le coût du chaos.

Infrastructure Engineers

Architectures cloud
Réseaux, load balancing
Provisioning, Terraform
Optimisation des coûts

Ce sont eux qui rendent possible le “scale sans douleur”.

Sécurité (SecOps / AppSec / CloudSec)

Posture de sécurité
Audits, SOC2, pentests
Secrets management
Zero-trust, IAM
Analyse des vulnérabilités

Ils protègent l’entreprise d’un risque qui n’arrive jamais “un peu”.
La sécurité, c’est binaire : ça tient… ou ça casse.

Merci Alban Lecocq, Frédéric Alix, Christophe

🔹 DevOps : ceux qui rendent la livraison fiable, rapide et reproductible

Le DevOps n’est pas une personne.
C’est une culture… mais dans la vraie vie, quelqu’un doit bien la porter.

Le travail d’un DevOps, ce n’est pas “faire des pipelines”.

C’est :
Mettre en place des CI/CD stables
Créer des environnements reproductibles
Automatiser les tests, les scans, les déploiements
Travailler avec les devs pour réduire le time-to-prod
Outiller la qualité : observabilité, monitoring, alerting
Industrialiser les bonnes pratiques : feature flags, rollbacks, trunk-based ou GitFlow, etc.
Définir des workflows qui rendent la livraison ennuyeuse (dans le bon sens)

Le DevOps permet aux devs d’aller vite sans casser.
Et permet au produit d’évoluer sans peur.

Merci Sébastien BLAISOT

👉 Ces rôles ne sont pas “support”.
Ce sont les fondations.
Et sans fondations solides, aucune architecture, humaine ou technique, ne tient longtemps.

Merci les gars 🙏
