Senior🎓
Top SchoolCarlos Alvarez is a frontend-focused full-stack engineer and founder with 9 years of experience building data-driven web apps across PropTech, EdTech, and IoT. He combines strong React + TypeScript frontends with Django/Python backends and Postgres, currently channeling that stack into ROI Explorer, an AI-powered real estate investment analytics platform spanning 11 countries. Previously he improved conversion and latency metrics at GoStudent by leading micro-frontend implementations, performance refactors, and an internal UI library, and at Danalto he bridged web apps with geospatial IoT systems and multilateration knowledge. Comfortable shipping product-facing features end-to-end, he has led testing strategies, migrations (Redux to Zustand), and internationalization efforts. Based in Barcelona, he pairs a Fine Arts background with a UX nanodegree, bringing a design-minded approach to developer tooling and analytics. He’s particularly adept at turning complex domain data (real estate, IoT telemetry, or educational workflows) into usable interfaces that drive measurable business impact.
