ENGINEERING IN MOTION · GUILHERME BRUNO DOS REIS
Senior Software Engineer & Tech Lead building scalable digital platforms across commerce, fintech and enterprise systems, with accessibility and operational quality treated as engineering concerns, not afterthoughts.
01 / SELECTED IMPACT
Enterprise digital commerce
Architecture, stability and continuous evolution of multi-tenant digital platforms supporting more than 50 U.S. restaurant brands, thousands of physical locations and high-volume digital operations.
Inclusive engineering
WCAG-aligned interfaces, semantic structure, keyboard navigation, focus management and accessible component patterns, informed by hands-on work and professional writing.
Production confidence
Observability, incident investigation, performance optimization, cloud modernization and structured production governance for critical environments.
Technical leadership
Architectural reviews, code review, mentoring, tech steering, production readiness and release governance, including authorization to approve production pull requests and deployments.
02 / JOURNEY
Senior Software Engineer & Tech Lead. Multi-tenant digital commerce, checkout, payments, authentication, loyalty, observability, architecture and production governance across U.S. restaurant platforms.
Founder and Software Engineer providing software development and technical services across digital commerce, fintech, hospitality technology and international client environments.
Financial applications and banking journeys including digital onboarding, PIX, boletos, transfers, batch payments, statements and receivables financing using modern Vue/Nuxt architectures.
03 / IDEAS & WRITING
September 2026 · Accessibility
Semantic HTML, keyboard accessibility, ARIA, focus management, accessible component APIs and reusable design patterns.
Read on Medium →August 2026 · Engineering practice
Integrating accessibility earlier into component development, developer tooling, design systems and automation.
Read article →04 / LAB
The Lab is where I explore ideas that aren't finished yet, including AccessLens, a research direction for surfacing accessibility issues earlier in the development workflow.
05 / RECOMMENDATIONS
Verified, author-submitted professional recommendations - with visible provenance rather than a wall of generic praise.
06 / UNDER THE HOOD
Accessibility, performance and progressive enhancement aren't badges added at the end. They are constraints that shaped this experience from the beginning - and you can check each one yourself by using the site (view source, tab through it, toggle reduce motion).
How the SHA-256 works: recommendations move through invitation → submission → email verification → author confirmation → immutable, hashed original → optional translation → publication → participation thank-you. Every step is server-side; nothing about the original text can be silently edited.

07 / ABOUT
My work sits at the intersection of software engineering, front-end architecture, digital accessibility, operational reliability and product experience.
Across digital commerce, fintech, banking, hospitality and e-commerce, I combine hands-on engineering with architectural decisions, technical leadership, troubleshooting and production governance.
