Skills
My Development Approach
I specialize in building robust backend applications using Laravel, NestJS, and Express.js with a strong emphasis on clean architecture, design patterns, and best practices for future scalability. Beyond development, I have hands-on experience with Linux server administration, Bash scripting, Docker, and Nginx — including real-world incident response where I identified and removed a cryptocurrency miner from a compromised server, rotated credentials, and hardened the environment. I'm actively working toward a career transition into DevOps engineering.
Key Principles:
- Follow best practices, SOLID principles, and design patterns for scalable architecture
- Build RESTful APIs with robust documentation and versioning
- Implement comprehensive error handling and logging
- Prioritize security, authentication, and data validation
- Optimize database queries and caching strategies across PostgreSQL, MySQL, and MongoDB
- Leverage Linux, Bash scripting, Docker, and CI/CD for reliable deployments
- Hands-on server security: incident response, malware removal, credential rotation, and environment hardening
