About Me

São Paulo, Brazil

Product-driven Software Engineer building scalable, user-centric platforms across high-traffic IoT and SaaS products. I leverage AI-assisted development to ship features faster, improve reliability, and accelerate product iteration at scale.

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

Senior Software Engineer

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
  • Spearheaded the integration of AI-assisted workflows (Claude Code, Cursor) into the software development lifecycle. Reduced average PR cycle time by ~55% and 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 and provisioned the entire AWS infrastructure as code with Terraform (EKS, ECR, ALB, ACM, IAM/IRSA, KMS) across 5 composable modules, with Kustomize-based K8s manifests, 4 GitHub Actions pipelines, VPN-enforced access, and zero-downtime rolling deployments with automatic rollback — achieving zero feature regression

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
  • Finance app solo developed with AI-assisted development (Claude Code): expenses, credit cards, installments, recurring payments, salary tracking, budgets, and real-time dashboard
  • Agentic platform powered by Gemini with function-calling: LLM selects and executes tools (SQL generation, expense creation, spending forecasting) from text, voice, and image inputs; pgvector similarity search caches intent embeddings to skip redundant LLM calls
  • MercadoPago payment integration: PIX QR codes + card subscriptions with HMAC SHA-256 webhook signature verification
  • Column-level encryption (pgcrypto) + Row-Level Security — multi-tenant data isolation at the database layer
  • Clean Architecture with dependency injection; shared Zod schemas enforce type safety across the monorepo
  • 116+ tests (integration + unit) with over 45 database migrations
  • Zero infrastructure cost up to ~1,000 users using free tiers (Cloudflare Workers 100k req/day + Supabase 500MB + 50k MAU)
