CTO at Lambda TT
São Paulo, Brazil
Summary
👤
Senior🎓
Top SchoolGabriel Guelfi is a pragmatic CTO and senior full‑stack developer with a decade of hands‑on experience designing ERPs, BPMs, CRMs and e‑commerce platforms from architecture through delivery. Based in São Paulo, he pairs solution architecture and cloud expertise with day‑to‑day coding—leading teams, defining tech stacks and implementing APIs, workflows and migrations from legacy systems. His work spans PHP, JavaScript frameworks (Vue/Ionic/Quasar), relational databases and AWS, and he has repeatedly modernized complex enterprise processes (notably a nationwide bank’s legal department and several ERP/BPM migrations). Colleagues rely on him for clear requirements mapping, technical diagrams and pragmatic rollout plans that include AI/data analysis where it adds value. He’s as comfortable sketching high‑level architectures as rolling up his sleeves to build the core features that make systems usable.
