I'm a systems-oriented software developer interested in how things work at every level of the stack — from low-level systems to web applications and infrastructure.

I enjoy building projects to deeply understand the tools I use.

• 🌐 Web applications
  Backend and full-stack systems built with Laravel, Drupal, and Python (FastAPI), focused on clean architecture, API-first design, maintainability, and scalable cloud-ready solutions.

• 🛠️ Infrastructure & tooling
  Daily use of Linux, Docker, and Ansible to automate environments, deployments, and development workflows.

• 🕹️ Game development
  Focused on game architecture, core systems, and tooling, prioritizing fundamentals over engine abstractions.

• 🧩 Operating system (hobby project)
  Educational operating system project exploring memory management, scheduling, interrupts, and hardware interaction. Focused on deep systems understanding.

• API-first and cloud-oriented system design
• Emphasis on scalability, observability, and performance
• Containerized development and deployment workflows
• Clean architecture and long-term maintainability

• 🎮 Game project
  Custom game systems and architecture (work in progress).

• 🧠 Operating System: LumenOS
  Educational / hobby OS focused on learning and experimentation with low-level concepts. (work in progress, to be on github soon).

• 📊 Bitcoin Watch (Vue 3)
  A frontend application consuming external APIs, upgraded to a modern Vue stack.

• ⏱️ GTimeTracker
  A lightweight time-tracking tool focused on simplicity and usability.

• 🔐 Infrastructure automation
  Ansible roles and automation projects:

  • ansible-php
  • ansible-letsencrypt
  • ansible-rsyslog
  • docker-php (archived)

• Backend: Python (FastAPI), PHP (Laravel & Drupal), API design, distributed systems, background processing
• Frontend: React, Vue.js, Web Components
• Cloud & DevOps: AWS (EC2, RDS, S3), Docker, Linux, CI/CD, Infrastructure-aware development
• Data & Messaging: PostgreSQL, MySQL, Redis, relational modeling, caching, queues
• Architecture: Clean Architecture, scalable systems, performance optimization
• Practices: Automated testing, OpenAPI documentation, CI/CD pipelines, containerized deployments
