Principal Engineer at Arco Educação Building scalable educational technology infrastructure that impacts millions of students across Brazil

I'm a Principal Engineer focused on frontend architecture at scale, microfrontends, design systems, and developer experience as a force multiplier. My work centers on creating coherent systems that reduce cognitive load, systemic risk, and entropy — enabling multiple squads to ship with consistency and confidence.

I approach problems with analytical depth and a preference for mechanisms over magic: governance frameworks (RFCs/ADRs), canonical documentation, observable pipelines, and automation that makes the right thing the easy thing. I also apply AI pragmatically in production contexts — RAG orchestration, evaluation pipelines, datasets, and quality gates.

Beyond corporate engineering, I build products that matter: privacy-first tools, intelligent transcription systems, and experiences that ship.

Frontend Architecture & Platform Microfrontends (Module Federation) • Design Systems (Iris DS) • Monorepo Architecture • Component Libraries • Build & Bundle Optimization • Runtime Performance

Developer Experience CI/CD Pipelines • Tooling & Automation • Engineering Governance (RFC/ADR/DCP) • Knowledge Management (WikiJS) • Standardization & Quality Gates • Reducing Cognitive Overhead

Applied AI & Data Systems RAG Orchestration (LangChain/LangGraph) • Semantic Search & Vector DBs • OCR/HTR Pipelines • Dataset Engineering & Quality Metrics (WER) • Observability (Langfuse) • Evaluation Frameworks

Full-Stack Engineering React • TypeScript • Angular • Node.js • Python • PHP • GraphQL • REST APIs • PostgreSQL • Self-hosted Infrastructure

Cloud & Infrastructure AWS • Azure • Docker • Coolify • Supabase (self-hosted) • Edge Functions • n8n Automations • Observability & Monitoring

Leading technical architecture for educational platforms serving thousands of schools and millions of students:

• Microfrontend ecosystem with Module Federation, enabling independent squad velocity while maintaining system coherence
• Iris Design System integration and governance across product surfaces
• AI-powered education tools: RAG systems over ~10k+ document bases, automated essay correction with OCR/HTR pipelines, semantic search infrastructure
• Developer Experience initiatives: canonical documentation (WikiJS), RFC/ADR processes, CI/CD standardization, quality automation
• Café com Código: recurring engineering community ritual for knowledge sharing and technical culture building

Remindr.AI — Privacy-first desktop app for intelligent transcription, diarization, and daily memory. Built for people who think while they talk.

Lofiever — Ambient productivity environment (active development)

I believe sustainable systems come from:

• Coherence over cleverness — systems should be predictable, not impressive
• Governance as enabler — lightweight structures (RFCs, ADRs) that prevent chaos without bureaucracy
• DX as leverage — remove friction and teams move faster with higher quality
• AI as engineering — observability, evaluation, datasets, and metrics; not magic
• Documentation as source of truth — canonical, versioned, discoverable
• Pragmatic depth — deep enough to be correct, simple enough to be maintainable

I work across three layers simultaneously:

1. Architecture & Governance — Long-term structures that outlive individual features: contracts between systems, version strategies, risk reduction, technical debt management

2. Platform & Tooling — Moving the needle for entire teams: automation, pipelines, standards, templates, observability, integration

3. Applied Technology — Shipping real value: AI orchestration, data pipelines, frontend infrastructure, full-stack features when needed

• Technical Writing: Arco Tech Blog, Medium, internal RFCs and architecture docs
• Speaking: Internal tech talks, meetups, engineering community events
• Open Source: Active on GitHub @MatheusKindrazki
• Mentoring: Technical interviews, feedback systems, engineering culture development
