About Me

São Paulo, Brazil

Product-minded engineer with 4 years of experience building products, not just features. Solo-built and monetized a financial control app from zero; led full-stack infrastructure migrations and shipped AI-assisted workflows that halved PR cycle time. Cares as much about what to build and why as how to build it.

I thrive on complex challenges. What brought me to programming was automating Excel spreadsheets, first with formulas, then with VBA. My Mechanical Engineering background, especially the physics and math, didn't lead me here, but it made me better at it. Calculating air resistance or modeling systems taught me to break down problems logically, a skill I apply to every technical challenge today.

Strong product intuition with hands-on cloud, distributed systems, and modern web expertise. I also love writing and sharing what I learn—because building great products is only half the fun if you can't communicate why they matter.

Professional Experience

Oct 2025 - Present

Product Engineer (Rehired for Leadership Role)

BWS IoT

Remote

  • Orchestrated the stabilization of Kubernetes-based infrastructure using EKS. Configured Traefik ingress, automated TLS (ACME), and implemented Prometheus/Grafana observability, resolving complex RBAC and pod scheduling bottlenecks
  • Diagnosed and re-engineered a critical gRPC connection handling flaw that caused intermittent service failures. Achieved 99.9% system availability and eliminated recurring downtime incidents under peak traffic conditions
  • Architected and led the adoption of AI-agentic workflows (Claude Code, Cursor) across the engineering team (5 engineers), slashing PR cycle time by 55% and establishing new standards for team productivity and code quality; improved First Time Pass Rate (FTPR) by mentoring the team on effective prompt engineering and agentic coding tools
  • Migrated a 56-page internal platform from a Next.js monolith to a decoupled monorepo (Vite + Fastify), reducing build time from 35s to 4s and production bundle from 105MB to 562KB (99.5% smaller)
  • Designed the full AWS infrastructure from scratch with Terraform (5 composable modules covering EKS, networking, IAM, and CI/CD), enabling zero-downtime deployments with automatic rollback — zero feature regression during the migration
  • Led the migration of a production ERP database from MongoDB to PostgreSQL with zero regressions, designing a repository abstraction layer that enabled swapping 17 data layers transparently from NoSQL to SQL, validated by 5 batches of E2E tests against a real database, ensuring the application continued operating seamlessly after a full database paradigm shift
  • Architected a pnpm monorepo with 4 packages, enforcing a single source of truth for entities, Zod validators, and DTOs across frontend and backend — eliminating client/server type drift and enabling shared validation logic consumed by both layers
  • Designed multi-environment CI/CD pipelines (GitHub Actions) with WireGuard VPN tunneling, AWS IAM role assumption via OIDC, ECR image caching, and automated rollback on failure. Optimized Docker images from 300MB to <100MB with 3-stage builds, configured Kustomize overlays for 3 environments (local/staging/production) with Pod Disruption Budgets, and enforced quality gates via Lefthook pre-commit, significantly decreasing CI/CD time and costs

Software Engineer

IntegrateIQ

Remote

  • Developed 15+ complex system integrations (HubSpot, Salesforce, etc.), automating data synchronization for 100k+ records daily and eliminating manual entry errors for enterprise clients
  • Built middleware endpoints with robust token refresh and authentication logic, resulting in a 40% reduction in integration-related support tickets
  • Led the architectural overhaul of a legacy web app using Vue and Node.js. Improved Lighthouse performance scores by 65 points and reduced initial page load time from 7.2s to 1.8s
  • Designed and deployed a reusable RBAC system using AWS Cognito and Serverless Framework, cutting the security configuration overhead for new applications by roughly 85%

Software Engineer

BWS IoT

Remote

  • Built a centralized design system and Storybook library across 3+ core products, increasing feature delivery speed by ~60% through component reuse and standardized UI patterns
  • Implemented a comprehensive end-to-end testing strategy with Cypress and Playwright. Achieved 85% coverage on critical user paths, leading to a 48% decrease in production bugs identified per release
  • Developed a real-time stock and delivery module integrated with Omie ERP. Introduced a Kanban-based workflow that increased order processing throughput by 2.4x and provided cross-departmental visibility into stage-by-stage lead times

Financial Control App for Brazilians

Visit
  • Solo-built finance app for Brazilians who track spending in spreadsheets and lack financial predictability. Designed around Brazil-specific patterns — installment purchases, multi-card management, and PIX — prioritizing simplicity over feature bloat
  • Built an AI assistant that lets users manage finances through text, voice, and photo inputs — the model selects and executes tools (SQL queries, expense creation, spending forecasts). pgvector embedding cache skips redundant LLM calls, keeping AI costs near zero
  • Integrated MercadoPago payments (PIX + card subscriptions) with HMAC-verified webhooks to monetize from day one
  • Architected for $0 infrastructure cost up to ~1,000 users by composing free tiers (Cloudflare Workers, Supabase, MercadoPago) — validating product-market fit before scaling spend
  • Data isolation and protection at the database layer (column-level encryption + RLS), not just auth-level separation
