Bruno Monteiro

DevOps & Security Engineer — Cloud Cost Optimization & Kubernetes

I help companies slash their AWS bills, architect production-grade Kubernetes clusters, and implement Istio service mesh for secure, observable microservices.

What I Do

💰

AWS Cost Optimization

I audit your AWS infrastructure, identify waste, and implement strategies that reduce your monthly cloud spend — often by 30–50% — without sacrificing performance or reliability.

☸️

Kubernetes Blueprints

Complete, production-ready Kubernetes cluster architectures — from node sizing and autoscaling to RBAC, network policies, and GitOps deployment pipelines. Built to scale from day one.

🔗

Istio Service Mesh

End-to-end Istio implementation for traffic management, mTLS encryption, observability, and canary deployments. I turn complex microservice communication into something you can actually manage.

🤖

AI-Accelerated Delivery

I leverage AI models to dramatically speed up development cycles — reducing time-to-delivery and the number of people needed for full-scope projects. Focused on shipping real deliverables, not busywork.

🚀

GitOps Build & Deploy Blueprints

Complete end-to-end pipelines: push your code and see the outcome. I deliver full blueprints covering packaging, container scanning, automated testing, and progressive deployment — so your team just commits and everything flows to production safely.

🔐

Identity & Access Management

Secure your organization with robust identity solutions. Experienced in Microsoft Entra ID — from SSO and conditional access to RBAC and zero-trust policies that protect your users and resources.

🌐

API Gateway

Production-proven API gateway deployments using open-source Tyk and WSO2. Rate limiting, authentication, analytics, and developer portals — all running reliably at scale without enterprise license costs.

📋

Consultancy & Full Project Delivery

From initial assessment to production handover — I offer end-to-end consultancy and full project delivery. I design the architecture across all components, take ownership of execution, and deliver results on time.

About Me

I'm a pragmatic and versatile Computer Science Engineer who specializes in making cloud infrastructure faster, cheaper, and more secure. I've helped clients save thousands per month on AWS while improving their system reliability.

My approach: audit first, then deliver a complete blueprint — optimized Kubernetes clusters with Istio service mesh, proper observability, and automated scaling. No half-measures.

I leverage AI models to accelerate every phase of delivery, reducing team size and time-to-market without compromising quality. Experienced in delivering end-to-end projects for Fortune 500 organizations.

Trilingual in English, Portuguese, and Spanish — comfortable collaborating across cultures and time zones. On-site experience in Portugal, Poland, and Switzerland.
