TNJ Alpine Technologies

TNJ Alpine Technologies is a Geneva-based software engineering and IT consulting company. We design, build and run custom digital products: SaaS platforms, marketplaces and aggregators, mobile apps, web applications, data pipelines and applied AI. Our team brings 15 years of hands-on experience across energy and commodity trading, finance and insurance, real estate and automotive, so we speak the language of the business as well as the codebase. Typical engagements: an MVP taken from wireframes to production in 8 to 12 weeks; an internal platform or back-office tool that replaces spreadsheets; AI assistants, agents and document automation built on your own data; analytics and big-data pipelines with dashboards your team can actually use; or taking over and stabilising an existing codebase. How we work: a small senior team, no layers of account management. Two-week sprints with a clickable environment from the first one, a fixed starting budget, weekly demos, and code and infrastructure that stay entirely yours. We build on React and Next.js, Node.js and Python, PostgreSQL and modern cloud infrastructure, and deploy in Europe with GDPR and Swiss data-protection requirements in mind. We also run our own product, Roogle, a multi-country rental listing aggregator for international students and expats, which keeps us honest about what it takes to ship, scale and operate software rather than just deliver it. We work in English, French and Russian with clients across Switzerland, the EU and beyond.
