Which technologies and business contexts are part of the experience?

Experience includes React, Next.js, Angular, Node.js, Nest.js, Express.js, MySQL, Docker, and Adobe Experience Manager across e-commerce, telecom, compliance, and private digital products.

How can I get in touch?

You can reach out by email at contato@glaubermag.dev.br or via LinkedIn at linkedin.com/in/glauberarielmagalhaes to talk about software engineering, React, Node.js, and related topics.

How does Glauber document architecture decisions?

Case studies include architecture and trade-off sections, data-flow diagrams, and short ADRs (e.g. HTTP-first scraping, SPA+prerender vs Next.js, pragmatic node-cron). The focus is why a decision was made, not buzzwords.

What impact metrics appear on the portfolio?

I do not publish business KPIs or numbers I cannot measure or confirm (product volume, real uptime, jobs/day, API latency). What appears is verifiable technical context: trade-offs in cases, real stack, ADRs, and on this site i18n and CI pipeline auditable in the public repository.

How does he act in technical leadership and mentorship?

Influence through documented technical work: junior support at Epsoft, code analysis tools in the Connor program, published technical articles, this portfolio’s CI pipeline (open source), and code review focused on security and explicit contracts — without inventing formal mentorship programs or team metrics.
