Who we are

One team.
One partner.

ATHENIX Technology is an engineering studio that turns ideas into profitable digital products. Web, mobile, business platforms, AI integrations — we handle everything from product scoping to production on proven stacks. For agencies, startups and companies across Europe and internationally.

Founded by Tanjona RAKOTONDRASOA — Developer, Technical Project Lead and CTO with 20 years of experience — ATHENIX brings together a team of engineers in the heart of the Indian Ocean, ideally positioned to work with Europe (1–2 hours from Paris) as well as the rest of the world.

Our stance: partner, not vendor. We work hand in hand with our clients, from product scoping to production, on modern stacks — React, Next.js, React Native, Node.js, Supabase, and AI integrations (Claude, GPT, RAG).

The cruise market relies on massive catalogs, continuously refreshed by each line.

DELIVERABLES

  • Real-time API feed aggregation from 4 major lines (MSC, Costa, Royal Caribbean, Croisière Europe).
  • Normalization of heterogeneous catalogs (itineraries, cabins, prices, availability) into a unified data model.
  • High-performance, SEO-optimized Next.js websites: cruise search, comparison and booking.
  • Admin back-office: content, offers and pricing-rule management.
  • Integrated CRM: lead tracking, follow-ups and sales-funnel steering.
