Hi, I'm Santosh Kafle, DevOps & Backend Engineer

My Engineering Approach

I work on both sides of the deployment line: the application code and the infrastructure it runs on. On the operations side that means reproducible Docker environments, CI/CD pipelines, Linux server administration, Nginx, and Bash scripting, with configuration kept in version control so an environment can be rebuilt rather than repaired. I treat observability as part of shipping rather than an afterthought, provisioning Prometheus and Grafana entirely from files so what a system is doing is measured instead of assumed. That carries through to when things go wrong. I identified and removed a cryptocurrency miner from a compromised React server-side rendering (SSR) host, rotated every credential, and hardened the server. On the backend I build with Laravel, NestJS, and Express.js, with a strong emphasis on clean architecture, design patterns, and best practices for future scalability.

Key Principles

• Architect reproducible environments with Docker, automate deployments via CI/CD, and manage Linux infrastructure
• Practice infrastructure-as-code thinking: version-controlled configs, automated provisioning, and environment parity across dev/staging/production
• Instrument what I run: metrics, dashboards, and datasources provisioned as code so system behaviour is measured rather than assumed
• Hands-on server security: incident response, malware removal, credential rotation, and environment hardening
• 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
