The Arc.
From decoding human language across borders to architecting high-performance systems — a decade of deliberate transformation.
2011 – 2012
Import Negotiations Interpreter
Infinity Stones · Guangzhou & Foshan, China
Brokered complex B2B import negotiations in Mandarin and English across Chinese manufacturing hubs. First exposure to the architecture of human communication under pressure — decoding intent, context and ambiguity in real time.
2012 – 2014
History Undergraduate
Universidade Federal de Goiás · Goiânia, Brasil
Studied historiography, critical analysis and the long arcs of human systems. Built the intellectual framework for understanding how complex structures evolve, fail and transform — a lens that would later inform software architecture.
2013 – 2016
English Teacher & Pedagogical Assistant
Wizard Idiomas · Goiânia, Brasil
Designed and delivered English curricula for hundreds of students. Mastered the craft of turning complex concepts into clear, structured frameworks — the same cognitive discipline now applied to systems.
2017 – 2023
Software Engineer
Faculdade Realiza · Goiânia, Brasil
Built web applications, CMSs and LMS platforms from the ground up. The core stack moved from NodeJS to Go, Svelte and PostgreSQL. First systems at institutional scale — authentication flows, content pipelines, SaaS integrations.
2019 – 2022
Brand & Graphic Designer
JOTA · Goiânia, Brasil
Developed brand identities and visual systems for clients across sectors. Internalised the design principles — hierarchy, contrast, negative space — that now govern UI architecture and the visual logic of this site.
2022 – 2023
Instructional Developer
Digibee · São Paulo, Brasil
Built integration pipelines, delivered technical bootcamps and shipped an internal education portal in TypeScript, Python and low-code tooling. First deep contact with event-driven architecture at scale.
2023 – 2026
CTO
Faculdade Realiza · Goiânia, Brasil
Led engineering strategy and execution across CMS, LMS, CRM and AI-integrated platforms, on Go, Svelte, PostgreSQL and Temporal. Built the institutional software layer that let a tech-forward school operate at scale — and closed the chapter in August 2026.
2023 – Present
Founder & Systems Architect
JoãoAfonso.Tech · Goiânia, Brasil · remote
Designing and shipping production systems for clients under my own practice: smart-locker IoT with Brazilian e-invoicing, affiliate and commission SaaS, HR platforms with legally valid digital signatures, multi-tenant back offices, and conversational software that runs on WhatsApp. Architecture decided by a decade of production; speed decided by AI.
