Why work with Marujos

Performance & Scale in Production

We analyze products in production to find what's limiting growth: slow queries, infrastructure bottlenecks, processes that can't keep up with demand. Based on the diagnosis, we point the way forward: evolve the current architecture, redesign a specific part, or simply adjust what's already there. Sometimes the right answer is still WordPress or well-structured PHP. The goal is to solve your business problem, not push new technology.

✦ Full diagnosis before any architecture decision.

AWS & Cloud Consulting

We help companies structure, optimize, and automate their AWS infrastructure. This includes quality and performance analysis of systems already in production, infrastructure-as-code automation with Terraform, and architectures that scale on demand, without relying on fixed servers or manual configuration.

✦ Documented, version-controlled infrastructure from day one.

AI Agents & Automation

We build custom AI agents to automate your team's operational tasks, create integrations via MCP (Model Context Protocol), and connect models like Claude to real workflows, hosted on AWS itself. We also build on-demand pipeline automations, taking repetitive work off the hands of people who should be focused on the product.

✦ Custom automation, without relying on a closed platform.

AI-Powered Validation: Performance & Security

We use AI tools to audit data pipelines in real time. We identify performance bottlenecks, access anomalies, and exposure vectors before they reach production. The analysis covers everything from slow queries and memory usage to compliance with security policies and sensitive data access control.

✦ Security flaws and bottlenecks caught before reaching production.

How we work

From diagnosis to operation.

A lean process built for teams that can't wait months for results.

01

Diagnosis

We map the current architecture, technical bottlenecks, and point out whether it's worth evolving what already exists or rethinking the solution from scratch.

02

Technical proposal

We design the solution with a clear stack, timelines, and success criteria.

03

Implementation

Continuous delivery, with frequent deploys and full visibility into progress.

04

Operation & Support

Post-delivery follow-up to ensure performance, security, and continuous evolution.
