Vinicius Vaz profile picture

Software Engineer working on cloud-native infrastructure. At Capgemini Engineering, with Nokia as the client, I run Helm rolling upgrades on Kubernetes for production telecom systems serving 5M+ subscribers and configure traffic routing for highly available services.

Systems foundation from 42 Lisboa (C/C++, Linux, processes), with hands-on experience in Docker, Nginx, Terraform and AWS.

Current Best Project
Projects
Solo AWS · Terraform
Photo Firefly

Cloud-based full-stack photography platform deployed on AWS, with all infrastructure written in Terraform (EC2, EBS, S3, ECR, Route 53, IAM). Least-privilege, SSH-free design: Secrets Manager and SSM for config, IAM instance roles instead of static keys, and a private encrypted S3 bucket for media. Low-cost single-instance architecture with a documented scale-out path to ECS Fargate, ALB and CloudFront. Integrates Stripe Checkout with signed webhooks, Google OAuth/Calendar and SMTP, covered by a Vitest suite.

Group C++ · HTTP/1.1

HTTP/1.1 server built from scratch in C++ with no external libraries. A single non-blocking poll() event loop serves multiple ports, static files, uploads and CGI (Python, Node.js), and handles malformed and slow clients.

Experience

Software Engineer · Capgemini Engineering

Jul 2026 – Present · Lisbon

Client: Nokia · Cloud-native telecom infrastructure

  • Execute Helm rolling upgrades on Kubernetes for 5G/4G subscriber registers (AUSF/UDM/HSS/HLR) in a network serving 5M+ subscribers, about 2 production rollouts per month with a zero-downtime design.
  • Troubleshoot deployment issues during live upgrades using kubectl and logs.
  • Configure traffic routing with Kubernetes Ingress and internal networking to support high availability across sites.
  • Use internal LLM tools in the incident troubleshooting workflow, cutting diagnosis time by about 3 hours.

About Me

Hi! I'm Vinicius Vaz Cascais, a Software Engineer based in Lisbon, currently focused on cloud and cloud-native infrastructure.

Day to day I work with Kubernetes, Helm and OpenShift on production telecom platforms, where upgrades have to land with zero downtime and every routing change matters. On the side I build and deploy my own projects on AWS with Terraform, aiming for secure, least-privilege and low-cost designs.

My foundation comes from 42 Lisboa and a background in network and systems administration: C/C++, Linux, processes and networking. Knowing what happens underneath the containers is what I enjoy most about cloud work.
