Vitor Alexandre

Backend and Platform Engineer. I build and scale cloud native systems, and I like turning architecture decisions into numbers that actually move.

I'm a Tech Lead at Pedbot, a chat commerce SaaS, a role I grew into from trainee over the last four years. Most of my time goes into the platform layer: Kubernetes, cloud architecture, real time systems, and the FinOps work that keeps all of it sustainable. On the side I build my own products end to end, from infrastructure to billing.


Core Expertise

Domain Focus
Platform Engineering Kubernetes on EKS and GKE, cloud architecture, self hosted infrastructure
FinOps Cost modeling, workload migration, keeping spend tied to business numbers
Real Time Systems Self hosted MQTT, WebSockets, webhook driven pipelines
Backend Laravel and PHP, Node.js, TypeScript, GraphQL APIs
Data PostgreSQL, Amazon Aurora, Redis, Metabase dashboards
Product Billing, Stripe integration, cost controls that keep products profitable
Observability New Relic, live KPIs, alerting baked in from day one

A few results I'm proud of

  • Brought real time infrastructure cost down by about 70% by moving from AWS API Gateway and Lambda to self hosted MQTT on Kubernetes.
  • Cut database cost by 46% migrating PostgreSQL to Amazon Aurora I/O Optimized.
  • Led the official Meta Business integration that lifted average ticket size by 60%.
  • Built the Metabase dashboards that gave the business live KPIs, landing an average NPS of 8.

Products I built end to end

  • Provaki (provaki.com) is an AI tutor for Brazilian public service exams. It answers questions grounded in the law, grades essays in about 30 seconds, and writes practice questions in the style of each board. It runs on Laravel, Nuxt, PostgreSQL, Redis, and Stripe, with hard cost controls so it stays profitable on a small budget.
  • ScopeVeil (scopeveil.com) gives you one API and one bill for Claude, GPT, and Gemini. It's a privacy first gateway where prompt content never gets logged, shipped as open core with an open source TypeScript SDK (@scopeveil/sdk).
