What I'm looking for

I seek SRE/DevOps roles where I can own scalable infrastructure, automate CI/CD, improve observability and security, work in Agile teams, and mentor engineers.

I am a Site Reliability Engineer focused on building scalable, reliable systems and automating operations through code. I combine software development and systems administration to take end-to-end ownership of service reliability and performance.

In my current role I set up and secured a hosted GitLab server, created GitLab CI pipelines, deployed applications with Docker, and authored Ansible playbooks to automate deployment and configuration. I developed backend modules for real-time attack detection using Scapy and Flask, and built routing/networking modules integrating CoreDNS, hostapd, and DHCPd.

I led a cross-functional team of engineers, a UI/UX designer, and a tester using Scrum/Agile practices to align delivery with product priorities. I also built an AI-powered chatbot backend integrating Hugging Face inference and a custom Arch Linux-based OS with systemd-managed services.

My internships strengthened my security and cloud-native skills: I implemented CI/CD on OpenShift with comprehensive security tooling, built dashboards with Grafana, automated tasks with Go, and deployed SIEM solutions to detect and validate security threats.
