Hi, my name is

Gustavo Akira

I build automation systems, platform integrations, and the infrastructure behind them.

I like building practical systems that make day-to-day operations smoother, safer, and easier for people to trust.

About Me

I currently focus on endpoint platform engineering across macOS, Windows, iOS, and Android environments. Day to day, I design automation workflows, define compliance controls, and build integrations that keep device operations reliable at scale.

I have supported teams in startups, mid-size companies, and enterprise environments, building integrations, automations, and internal tools that solve real workflow problems.

Based in São Paulo, Brazil and working with teams across the globe.

Degree in Systems Development and Analysis - FIAP – Faculdade de Informática e Administração Paulista, January 2025.

ARCHITECTURE

Infrastructure Architecture

This portfolio runs on a Linux VPS behind a single reverse proxy that centralizes TLS termination and routes traffic to isolated backend services. Each service is supervised by systemd with defined restart policies, while health monitoring validates runtime availability and supports fast recovery. The result is an operational model focused on reliability, clear service boundaries, and predictable behavior in production.

Security note: Administrative access is restricted and protected through layered host-level controls.

Reverse Proxy & TLS

A central reverse proxy handles HTTPS termination and routes all incoming traffic to internal services. No backend is exposed directly to the internet.

Service Management

Every application is managed by the OS service manager. Services start on boot and restart automatically on failure, with no manual intervention needed.

Learn more →

Health Monitoring

Lightweight periodic health checks detect when a service goes down and send email alerts, keeping the stack observable without heavy tooling.

Learn more →

Hosted Services

Alongside this portfolio, the same server runs a webhook receiver, a JSON data API, and a self-hosted developer environment, all behind the proxy.

Subdomains

Each service lives on its own subdomain. Caddy handles TLS for all of them and proxies traffic to the relevant backend on localhost.

Projects

A selection of projects I've built. Admittedly, I wish I had more time to work on open source contributions, but here's what I've managed to create so far.

outbound-shell

Problem: admins needed remote access without opening inbound exposure. Solution: built a secure outbound-shell approach for controlled sessions. Relevance: improved maintainability for distributed Linux operations.

Python

CICD_Pipeline

Problem: release flow was inconsistent across environments. Solution: implemented CI/CD with automated build, containerization, and deploy stages. Relevance: made releases repeatable and lower risk.

C#

ipoffice-users-xml

Problem: telephony user data was hard to inspect in raw exports. Solution: built a parser that turns XML into actionable configuration views. Relevance: sped up troubleshooting and reduced analysis effort.

Python

api-quickview

Problem: validating private APIs required repetitive manual requests. Solution: developed a browser extension for fast request testing. Relevance: accelerated integration workflows and reduced context switching.

Impact

Some of my latest wins, framed in terms of outcomes, not tools.

Automated endpoint workflows to remove recurring manual steps and improve execution consistency at scale.

Eliminated 100+ hours of annual manual work by shipping internal automations for cross-functional teams.

Reduced detection and recovery time by implementing telemetry-backed monitoring and remediation flows.

Integrated endpoint platforms with internal services to streamline enrollment, compliance handling, and fleet operations.

What I Like Building

I gravitate toward work at the systems layer, where software meets infrastructure and operations.
