⚑ Hi, I'm Trung

Platform & Data Engineer | DevSecOps Architect | πŸ“ Vienna, Austria

I engineer high-availability, compliant infrastructure and secure data pipelines for heavily regulated industries. By bridging the gap between raw systems engineering, data streaming, and security governance, I build platforms that are fast, resilient, and audit-ready.

πŸ”­ Current Focus

  • Domain Expertise: FinTech, Bio, and Healthcare Infrastructure.
  • Platform Engineering: Architecting zero-downtime, bare-metal container orchestration and infrastructure as code (IaC).
  • Data Engineering: Building privacy-preserving, high-throughput event streaming pipelines and resilient database topologies.
  • DevSecOps & Compliance: Enforcing PCI-DSS and DORA compliance through automated vulnerability scanning, strict IAM, and zero-trust architectures.

πŸ’» Technical Arsenal

High-impact profiles present their stack as an organized grid and categorize technologies by layer.

Category Technologies
Cloud & Infrastructure Kubernetes, Docker, Proxmox VE, Linux (Debian)
Automation & IaC Terraform, Ansible, CI/CD Pipelines
Data & Messaging PostgreSQL, Apache Kafka, Vectorized Python (Polars)
Systems Programming Go, Rust, C++, Python, Bash
Security & Observability HashiCorp Vault, Prometheus, Grafana, IAM

πŸ›οΈ The Archive (Past Experience): My foundation was built in full-stack software development. I have deep past experience architecting applications using Java (SpringBoot), TypeScript, React, and Node.js. I still leverage this software engineering mindset today to build better internal developer platforms.

⚑ Fun Facts & Workflow

  • Editor of Choice: 100% terminal-centric. You will find me living inside Neovim, Tmux, and CLI-based AI agents.
  • Downtime: When I'm not tuning write-ahead logs, I'm usually optimizing grand strategy campaigns in Hearts of Iron IV or surviving boss fights in Sekiro.
