Developer & Tech Resume: How to Pass ATS Screening in Brazil

Even experienced developers often get filtered out by ATS before a recruiter ever reads their resume. The reason is almost never lack of skill — it’s missing or misformatted keywords. This guide covers how to structure a developer, data engineer, or DevOps resume to pass Brazilian ATS filters and reach the hiring manager.

Why tech resumes fail ATS screening

The most common mistakes: listing technologies as images or skill bars (like Canva templates do), writing acronyms without the full name, or burying the tech stack in a single section at the bottom — far from the experience entries where they were actually used.

ATS systems compare your resume word-for-word against the job description. If a posting asks for “React” and you only wrote “ReactJS”, you may lose points depending on the system. Cover the common variations.

Ideal structure for a tech resume

Header

Name, email, phone, city/state, LinkedIn, and a GitHub link (or portfolio). For developers, GitHub in the header is nearly mandatory.

Technical summary — the 5 most important lines

This section sets the tone for the whole resume. Include: the job title you’re targeting, years of experience, your primary stack, and one differentiator.

Example: “Full Stack Developer with 5 years of experience in React, Node.js, and PostgreSQL. Background in high-availability systems serving 500k+ active users. AWS Solutions Architect certified. Strong focus on performance, clean code, and continuous delivery.”

Tech stack — its own section

Create a dedicated section organized by category. This helps both human readers and ATS parsing.

• Languages: JavaScript, TypeScript, Python, Go
• Front-end: React, Next.js, Vue.js, Tailwind CSS
• Back-end: Node.js, Express, Fastify, Django
• Databases: PostgreSQL, MongoDB, Redis, MySQL
• Cloud & DevOps: AWS, GCP, Docker, Kubernetes, CI/CD
• Tools: Git, GitHub, Jira, Figma

Only list what you’ve genuinely used in a professional environment or in meaningful projects. Padding your stack is caught in the first technical interview.

Work experience with technical impact

For each role, go beyond listing responsibilities. What did you build? What was the outcome?

Weak: “Worked on feature development for the platform.”

Strong: “Built a checkout module with React and Node.js that reduced load time from 4s to 800ms, increasing conversion by 18%.”

Personal / open-source projects

Essential for career changers or those with under 2 years of experience. For seniors, a strong differentiator. Per project, include: project name + GitHub/demo link, stack used, what it does (one sentence), and scale or users if applicable.

Keywords by specialization

For a broader reference, see the full list of technical keywords by area — useful for checking you haven’t missed a term the ATS expects.

Front-end Developer

React, Next.js, Vue.js, Angular, TypeScript, JavaScript, HTML5, CSS3, Tailwind, Styled Components, Redux, Zustand, Vite, Webpack, responsive design, accessibility, web performance, Core Web Vitals.

Back-end Developer

Node.js, Python, Java, Go, REST API, GraphQL, microservices, Docker, PostgreSQL, MongoDB, Redis, JWT authentication, OAuth, unit testing, TDD, CI/CD, messaging (RabbitMQ, Kafka).

Data Engineer

Python, SQL, Spark, Airflow, dbt, BigQuery, Redshift, Snowflake, ETL, data pipelines, data lake, data warehouse, Kafka, Pandas, PySpark.

DevOps / SRE

AWS, GCP, Azure, Kubernetes, Docker, Terraform, Ansible, Jenkins, GitHub Actions, monitoring (Datadog, Grafana, Prometheus), SLA, SLO, incident response.

Mistakes that get tech resumes rejected

• Listing stacks without context — the ATS may score it, but the human recruiter wants to know where you used it
• Missing variations— write “JavaScript (JS)”, “Node.js”, “ReactJS / React” to cover different search patterns
• Two-column templates — stack on the left, experience on the right is one of the most ATS-hostile layouts
• Omitting certifications — AWS Certified, Google Cloud, Azure, Scrum are keywords ATS systems explicitly look for

Tech company ATS is more demanding

Companies like iFood, Nubank, Mercado Livre, and Totvs configure their ATS specifically to filter on tech stacks. Candidates who don’t clearly describe the required technologies in their resume rarely reach human review.
