Welcome, I’m Felipe Silva de Mello, a Senior Software Engineer based in Dublin, Ireland (Swords; Brazilian · Irish).

I am completing a part-time Master’s in Advanced Software Development at Technological University Dublin (Sept 2023 – present)

I am passionate about technology, staying current with emerging trends, keeping up with the ecosystem, and investing in hands-on learning so I can adopt new ideas that actually improve reliability, security, and delivery.

With 7+ years in European banking and fintech, I specialise in Java, Spring Boot, microservices, and DevOps with an emphasis on observability and shift-left approaches.

Deep diving into AI Engineering and Cloud infrastructure, I focus on developing resilient Microservices that bridge the gap between intelligent automation and scalable, modern platform engineering.

My recent work includes cloud migration, Kubernetes, containerization, CI/CD, automation, and end-to-end monitoring.

Live site:

• AWS Cloud Front - DNS In progress: Portofolio Hosted on AWS

• Git Hub Pages: felipedominus.github.io/portofolio

• What it is: A React + Vite portfolio (projects, experience, case studies—personal views only, not employer statements).

• How it ships: GitHub Actions runs on pushes and pull requests (install → lint → production build). A deploy job publishes the dist/ static build to GitHub Pages so the public *.github.io URL stays aligned with the repository—no separate manual upload for that hosting path.

• Repository: felipedominus portofolio.

November 2024 - Present · European Risk Finance Technology (ERFT)

• Key Responsibilities:

  • Migrate applications from Linux servers to Kubernetes and containerize workloads for repeatable deploys.
  • Manage Kubernetes clusters and platform concerns: Secrets, ConfigMaps, and cloud-aligned choices for storage, app configuration, and sensitive data.
  • TLS / certificates: generate and manage certificates for services running on Kubernetes.
  • Ansible: use Ansible Vault for passwords and sensitive variables; write playbooks that automate tedious or error-prone tasks; orchestrate cascading releases with Bitbucket across environments.
  • CI/CD: pipelines that build, validate, and promote applications into Kubernetes safely.
  • Monitoring: keep environments observable and healthy (metrics, logs, alerts) alongside platform delivery work.
  • Run automated CVE scanning and reporting to support security and audit readiness.
  • Build and maintain Splunk dashboards (UI performance, screen load, errors; comparative MoM / YoY views).
  • Engineer Splunk alerting on HTTP errors with email notifications to reduce MTTR.
  • Champion shift-left quality: automated unit, integration, and UAT suites in Docker, maintain strong code coverage.
  • Improve developer experience with Kubernetes-based patterns so teams rely less on heavy local backends.
  • Use GitHub Copilot agents (custom skills) for repeatable engineering tasks.

• Key Achievements:

  • Established weekly vulnerability scanning and reporting ahead of formal security audits.
  • Delivered observability views that support faster incident understanding and trending.
  • Reduced deployment failures through automated testing discipline in CI/CD.
  • Drive Linux-to-Kubernetes migration and containerization initiatives with automation-first Ansible and CI/CD practices.

• Technologies Used:

  • Kubernetes, Docker, Linux, Ansible, Ansible Vault, Bitbucket, Splunk, TLS / certificates, Secrets & ConfigMaps, cloud storage patterns on Kubernetes, CI/CD, GitHub Copilot, Java / Spring ecosystem (as required by ERFT delivery).

Outside my day job, I experiment constantly with AI-assisted engineering tools—Cursor, Gemini CLI, Codex, ChatGPT, and the wider ecosystem. I signed up from ChatGPT's first release, so I've been learning and evolving with the technology as it matured. I focus on skills, agents, and fine-tuned instructions so models remain useful, accurate, and safe for real-world development—not novelty demos.
