The Platform Engineer Who Ships Code Too.

I design Kubernetes platforms, CI/CD pipelines, and cloud architectures that feel fast for developers and boring for SREs, because I've been on both sides.

What I Do

I sit at the intersection of infrastructure, developer experience, and cost, with a full-stack background that bridges platform and product.

Kubernetes & Cloud Platforms
EKS, GKE, Talos Linux, Karpenter, hybrid cloud, and on-prem integrations.
CI/CD & GitOps
ArgoCD, GitHub Actions, GitLab CI, Jenkins, CircleCI, policies, and promotion flows.
Observability & Cost
Prometheus, Grafana, Dynatrace, CloudWatch, Kubecost, and SLO-driven decisions.
Developer-Friendly Infra
Terraform, CloudFormation, and automation written by someone who also builds backend services: infra that engineers can actually understand and own.

Teams I've worked with ship faster, get paged less, and spend less on cloud. Usually all three.

Experience

DevOps Engineer

Rivalry.com · Remote · Oct 2024 – Feb 2026

Rivalry is a global betting company where downtime and latency are directly tied to revenue. I worked across platform and backend, keeping the infrastructure solid while also building the services running on top.

  • Designed and implemented a high-performance Go backend middleware replacing a fragile multi-database aggregation layer: parallel MySQL queries across regions, result merging, and application-level pagination and filtering.
  • Designed and operated hybrid infrastructure across AWS and on-prem, keeping services highly available even under traffic spikes.
  • Led the migration from MicroK8s to Talos Linux, increasing cluster security, standardization, and operational confidence.
  • Introduced ArgoCD-based GitOps, which made deployments repeatable, auditable, and significantly faster.
  • Deployed Karpenter to right-size compute and autoscale EKS nodes, reducing waste while keeping performance.
  • Replaced a managed Pusher subscription with self-hosted Soketi, cutting recurring costs without sacrificing capabilities.
  • Implemented Kubecost and resource right-sizing, giving the team a clear picture of where the cloud money was going.
  • Modernized PHP infrastructure, migrating to FrankenPHP, simplifying the stack and improving performance.

Fewer surprises in production, faster releases, real cloud savings, and backend services that handle the load.

Services

Platform & DevOps Audit
Something feels off — the infra is too slow, too expensive, or too brittle to change. I review your platform, CI/CD, cloud setup, and costs end-to-end, then hand you a concrete plan your team can act on. No slides, no abstract recommendations.

Good fit if you:

  • Infra is becoming a bottleneck as the company scales.
  • Want a second opinion on your Kubernetes, GitOps, or cloud setup.
  • Need leadership and engineering aligned around a realistic platform plan.
Kubernetes & Cloud Engineering
From new clusters to complex migrations, I design and build Kubernetes platforms and cloud infrastructure that teams can operate long-term — not just get running once and hope for the best.

Good fit if you:

  • Planning a migration to Kubernetes or re-architecting an existing cluster.
  • Need multi-account or multi-region infrastructure on AWS or GCP.
  • Want someone who understands the workloads running on top, not just the infra.
CI/CD & GitOps
Deployment pipelines your engineers don't dread. I build GitOps workflows with ArgoCD, pipelines with GitHub Actions or GitLab CI, and promotion flows that are safe without being slow.

Good fit if you:

  • Your team spends too much time on manual approvals and broken pipelines.
  • Want merge-to-main → production without losing control or confidence.
  • Trying to move from ad-hoc scripts to a well-structured GitOps model.
Full-Stack Development
When the platform needs actual services built alongside it. Go APIs, Node.js backends, React interfaces — written by someone who has spent years on both sides of the infra/app boundary.

Good fit if you:

  • Need backend services or APIs built in parallel with platform work.
  • Want a full-stack perspective on architecture, not just an ops view.
  • Have platform and product work that benefits from one person who can do both.

About

João Victor Carvalho

I started my career in web development and moved through front-end, backend, DevOps, and Platform Engineering. That path gives me an unusual vantage point: I understand what makes infrastructure painful for engineers because I've been that engineer. My main focus today is DevOps and Platform Engineering: designing clusters, pipelines, and cloud architectures that accelerate teams. But I'm also open to full-stack work, and having built Go services, React apps, and Node.js APIs myself means I know what the platform needs to support them well. Outside of work, I experiment with side projects like rewriteIt.me and contribute to tooling when I can.

If your platform feels fragile, slow, or too expensive, I can help you:

  • Make Kubernetes clusters reliable and maintainable.
  • Turn your CI/CD into a competitive advantage instead of a tax.
  • Understand and reduce cloud costs without losing reliability.
