Summary
👤
Senior🎓
Top SchoolRoberto Loja is a solo developer with 11 years of software engineering experience who builds user-centered full‑stack applications that blend language learning and NLP. He designed and implemented mandoBot — a Django REST API with PostgreSQL and a Next.js TypeScript frontend — to visualize Mandarin sentence segmentation, word and character definitions, and pronunciation using research-backed "comprehensible reading" techniques. His background in computer engineering and philosophy gives him a practical engineering discipline paired with a human-centered, research-minded approach to product design. Prior roles range from automating large-scale mobile test suites at Rakuten Kobo to migrating legacy iOS apps to SwiftUI and leading feature development for high‑traffic consumer apps. He’s comfortable owning systems end-to-end, from prototyping and CI/CD to production monitoring, and is actively learning Mandarin while building tools to accelerate others’ learning.
