3 mistakes that are killing your dev resume

Ryan Machado — Sun, 30 Nov 2025 17:06:46 +0000

A dev resume isn't just a list - it's a context + impact sales doc.

After reviewing more than 25 developer resumes (mobile, backend, fullstack, career changers, etc.), the same 3 mistakes kept showing up.

1. Talking tasks, not impact

The most common error: the whole resume is written like this:

"Development and maintenance of applications..."
"Worked on bug fixes and new features..."
"Responsible for system X..."

That says nothing about:

the size of the problem,
how hard what you did was,
the impact on the product or business.

Recruiters read this all day. It turns into noise.

Fix: turn each bullet into technical action + what + how + metric/scale

2. Layout that kills ATS and readability

Another classic: a beautiful resume full of columns, icons, colors, emojis, and creative UX...

and completely indigestible for someone who needs to read fast (or for an ATS).

Lots of people fell into these:

Multi-column layout, heavy sidebar, icon, emoji in dates, cluttered header
Inconsistent dates and sections ("Aug 24", "08/2024", "2024 - present")
Important sections missing or weak: Projects, poorly separated Skills, giant text blocks

Fix: One column only

3. Stack misaligned with experience (or too shallow)

Saw this a lot:

giant skills list (Java 8 years, Docker, Kubernetes, AWS, Flutter, React...) without showing it once in roles
technologies only in the "Skills" section, zero proof in experience or projects
missing basic dev keywords: Git, testing, CI/CD, REST API, cloud, even for people who clearly use them daily
career in infra/support or teaching, but resume saying "full-stack dev" without a real project/product described

Fix: Only list tech you can defend in an interview and tie each one to a role or project.

Setting Up a VPS with Docker: A Step-by-Step Guide

Ryan Machado — Sat, 03 May 2025 21:17:17 +0000

Running applications in the cloud gives you reliability, accessibility, and the power to scale. In this guide, I'll walk through setting up a Virtual Private Server (VPS) with Docker, using environment variables to make this guide reusable for your own projects.

Prerequisites

Before we begin, set these variables according to your project:

# Your server details
export SERVER_IP="your-server-ip"
export DOMAIN="your-domain.com"
export PROJECT_NAME="your-project-name"

# User credentials for deployment
export DEPLOY_USER="deploy"
export DEPLOY_EMAIL="${DEPLOY_USER}@${DOMAIN}"

🔑 Connecting to Your VPS

First, connect to your newly provisioned server:

ssh root@${SERVER_IP}

🔧 Installing Docker

After connecting to the server, install Docker:

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo \"${UBUNTU_CODENAME:-$VERSION_CODENAME}\") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io -y

🌐 Configuring DNS

Create a DNS A record pointing your domain to the server IP. Once propagated, you can SSH using the domain:

ssh root@${DOMAIN}

🐳 Creating a Docker Context

To make working with remote Docker commands easier, create a Docker context:

docker context create ${PROJECT_NAME} --docker host=ssh://root@${DOMAIN}
docker context use ${PROJECT_NAME}

Now all Docker commands will run on the VPS via this context.

🚀 Setting Up Docker Swarm

Initialize Docker Swarm on your VPS:

docker swarm init # Optionally add: --advertise-addr ${SERVER_IP}

The command will output a join token. Save this for adding worker nodes later if needed:

# Example output - your token will be different
docker swarm join --token SWMTKN-1-xxxxxxxxxxxxxxxxxxxx ${SERVER_IP}:2377

📦 Deploying Your Application Stack

Deploy your application stack using docker-compose:

docker stack deploy -c docker-compose.yml ${PROJECT_NAME}

Your application should now be accessible at:

http://${DOMAIN}

To check service logs:

docker service logs ${PROJECT_NAME}_app

Conclusion

You now have a production-ready Docker environment on your VPS with a secure deployment user. This setup provides a solid foundation for running containerized applications in production with proper separation of concerns.

How to install Flutter + My Flutter Experience so far

Ryan Machado — Sat, 16 Nov 2024 18:19:18 +0000

In my job @twiage, we have a flutter project called STAT, which is a rewrite of an native implementation. I've never liked Flutter/Dart and was always uncomfortable working with it.

I've been playing with Flutter and React Native since 2020 and until the last couple of days, React Native was go to solution and Flutter was something that i considered "crappy".

It was so comfortable with React Native and had a chance to work in the RN@0.72.0 (i tell this everyone 🥹)

Here's why i loved React Native:

Typescript
Massive community
99% of JS libraries work with RN
Easy to install
Expo

Flutter problems

I had hard feelings about Flutter because the language (JS/Dart) differences and for being an React Native direct competitor.

Dart

I could never pardon Dart for trying to replace Javascript. This almost made us enemies for life.

Dart is a whole new language, not tied to Javascript, neither trying to keep backwards compatibility.

Flutter Installation

Don't get too carried away thinking that you're going to run your package manager install command with ease. Flutter installation is way more complex

To get things done, i've used my loyal companion asdf, so a big part of the pain went away.

So here's my step by step way to do it:

1. Install Flutter

asdf plugin add flutter
asdf install flutter latest

2. Get mad at Flutter for not telling you the correct JDK version from start

Actually, this is my fault, if you run flutter doctor, the CLI will give you a warning about the mismatching JDK version. (this is still pretty annoying tho)

Install JDK 17 (or whatever version is required by Flutter by the time you're reading this)

asdf plugin add java
asdf install java adoptopenjdk-17.0.0+12
asdf local java adoptopenjdk-17.0.0+12 # will create your .tool-versions

you can set the JDK that Flutter will use by passing the --jdk-dir flag -- and you can get this value by running asdf where java

flutter config --jdk-dir $(asdf where java)

3. Create a new Flutter project

flutter create myapp
cd myapp
flutter run

Conclusion

This guide should help you installing the Flutter SDK and the required JDK using asdf, which is a really handy tool.

asdf can be used with a big variety of languages and runtimes, take a look at their website for more information.

Thank you very much for readying my article, let me know if I can help with anything in your projects.

Prazer, MobX: uma solução de gerenciamento de estado para aplicações React

Ryan Machado — Sat, 03 Feb 2024 13:43:55 +0000

TLDR: Mobx é uma solução de gerenciamento de estado: Nesse artigo escrevo um pouco sobre a teoria por trás do funcionamento

Link de exemplo com react

Link da documentação

Não existe maneira melhor de criar aplicações bugadas e difíceis de manter do que não gerenciar corretamente o estado da sua aplicação.

Mobx busca fazer isso de maneira simples ao arrancar a raiz do problema: fazendo com que seja muito difícil criar estados inconsistentes.

Para entender melhor como o MobX funciona, vamos começar pelo básico: o estado da aplicação. O estado da aplicação é basicamente todos os dados que são usados pela aplicação e que podem ser alterados ao longo do tempo. No React, esses dados geralmente são mantidos no componente de estado, mas com o MobX, podemos mantê-los em qualquer lugar.

As derivações são valores que podem ser calculados a partir do estado da aplicação. Por exemplo, se o estado da aplicação inclui um array de números e você quer saber a soma desses números, essa soma seria uma derivada. O MobX permite que você defina essas derivações de maneira fácil e as mantém atualizadas automaticamente sempre que o estado da aplicação for alterado.

As reações são basicamente como as derivações, mas em vez de produzir um valor, elas fazem alguma coisa quando o estado da aplicação muda. Por exemplo, você pode definir uma reação que atualize o DOM sempre que o estado da aplicação mudar. O MobX garante que as reações sejam executadas de maneira síncrona e sem problemas sempre que o estado da aplicação mudar.

Por último, temos as ações. As ações são todas as coisas que alteram o estado da aplicação. No MobX, todas as ações são processadas por derivações e reações, o que significa que todas as alterações no estado da aplicação são feitas de maneira síncrona e sem problemas. Isso é útil porque garante que não haja problemas como estados inconsistentes ou alterações no estado que não são refletidas corretamente na interface do usuário.

Em resumo, o MobX é uma ferramenta útil para gerenciar o estado da sua aplicação de maneira fácil e consistente. Ao permitir que você defina derivações e reações para manter o estado da aplicação atualizado, ele torna mais fácil criar aplicações robustas e sem problemas. Se você está procurando uma maneira de gerenciar o estado da sua aplicação com o React, definitivamente deve dar uma olhada no MobX.
