Kolus.io

Kolus.io November 2021 - January 2023

💡 Concept

Direct successor to Tikaway, Kolus aimed for massive adoption through radically simplified UX: 'One link, one click, it works'. No complex installations.

👨‍💻 Role

CTO & Co-creator. I redesigned the entire user and technical experience to eliminate usage friction.

⚡ Highlights

  • 'Zero-Friction' UX: Total redesign of flows to enable video connection in under 10 seconds, with no app to install.
  • 🗺️ React Flow: Creation of a visual support workflow editor (decision tree type) to guide autonomous customers.
  • 🛠️ Robustness: Ticketing and video system capable of operating in industrial environments with poor connectivity.

📈 Impact

🚀 Immediate adoption by clients thanks to simplicity. Project successfully led from creation to acquisition.

LVL UP January 2025 - September 2025

💡 Concept

Today, many schools still manage everything on paper or Excel: no synchronization, missed payments, no student access... LVL UP digitizes and simplifies it all.

👨‍💻 Role

⚡ Highlights

  • 💳 Complex Financial System: Management of recurring payments, custom installment plans, and unpaid tracking.
  • 🔄 Real-Time & Roles: Immediate data synchronization between Admin view (school) and Student view.

About me

I design and build SaaS products, mobile apps, and AI integrations that deliver: a solid architecture, a simple UX, and fast delivery.

My role: handling the technical complexity so you can have total peace of mind: my goal is to solve your problems sustainably, prioritizing clarity and efficiency.

  • Architecture: clear boundaries, separation of concerns, pragmatic design.
  • Quality: clean code, SOLID principles, code reviews, and controlled tech debt.
  • Testing: Jest & Playwright, TDD when it fits the context.
  • Delivery: CI/CD, environments, reliable deployments.
  • Collaboration: Agile, short iterations, fast feedback, useful documentation.
  • Cloud: AWS / Azure depending on your standards.

I work in short iterations, with simple and transparent communication: regular demos, prioritization, and focus on what creates the most value.

My Added Value

🎨 Product Vision & UX

I'm not just an executor. I think "user-first" before code to build fluid, pragmatic, and high-impact experiences.

🤝 Strategic Partner

I challenge your ideas and bring a fresh perspective to turn your vision into a viable and profitable technical roadmap.

🧠 Rigor & Autonomy

Absolute reliability. I anticipate risks, prioritize quality (SOLID principles), and deliver on time.

🗣️ Communication & Human

Total transparency and active listening. I demystify tech so you remain in control of decisions.
