I'm a Software Engineer with over a decade of experience in technology. I started my career working with Linux servers and networks, then moved into building and scaling web applications — while continuously exploring systems, security, tooling and software architecture out of genuine curiosity.

Technology is both my profession and how I think.

• Backend-focused Software Engineer
• Strong background in Linux, infrastructure and operations
• Security-aware mindset, influenced by offensive security studies
• Curious by nature — I enjoy understanding how systems work and how they fail

• PHP / Laravel (since version 4.x)
• Python (FastAPI, Airflow)
• REST APIs and distributed systems
• MySQL, PostgreSQL, MongoDB, Redis, RabbitMQ
• Docker, CI/CD pipelines, Kubernetes, cloud environments (AWS, Azure, DigitalOcean)
• Automated testing and TDD practices
• Monolithic and microservices architectures

• Coeur — a personal static site compiler designed to handle large content-heavy websites

  • Built as a modular Python CLI
  • Manual SQLite sharding to handle large datasets
  • Memory-efficient processing using Python generators
  • Focus on predictable performance and low resource usage

• Rust & WASM experiments

  • Study notes and experiments around Rust fundamentals and memory safety

  • Small WebAssembly experiments to understand Rust ↔ browser boundaries

  • Exploring distributed networking concepts using Rust and JavaScript

• Linux internals & networking

  • Shell scripting, system behavior, process and network-level understanding
  • Background influenced by years of Linux server and network administration

• Pentesting labs & offensive security practice

  • Formal training in offensive security (4Linux)
  • Hands-on labs using Hack The Box
  • Focus on attack surfaces, misconfigurations and real-world failure modes
  • Applied mainly to improve secure system design and code reviews

• Programming languages & abstraction trade-offs

  • Studying how different languages shape architecture, performance and maintainability

Alongside engineering, I’ve studied and applied concepts related to operational maturity and delivery:

• Project and operations management fundamentals (PMI)
• IT service and process management (ITIL)
• Governance and control frameworks (COBIT)
• Agile methodologies (Scrum, Kanban)

This helps me reason not only about code, but about systems, teams and delivery over time.
