Moodle LMS on a bare-metal k3s cluster
A production learning platform with CodeRunner/Jobe grading services on dual Intel Xeon Gold 6430 servers, holding steady through real classroom load of 1,000+ concurrent users.
I run a bare-metal Kubernetes (k3s) cluster serving 1,000+ concurrent users, a self-hosted Cloudflare Zero Trust edge, and the CI/CD that ships to both. Container orchestration, DNS and SSL, networking, observability — I own the whole path from commit to production.

Final-year B.E. Computer Science (Cyber Security) at Sri Shakthi Institute of Engineering and Technology, Coimbatore — and, since 2023, the person who keeps a homelab-turned-production environment alive: Cloudflare Tunnel and Tailscale for access, OpenWRT for the network, Prometheus and Grafana for the truth about what is happening.
At TeamMistake Technologies I worked both sides of the line — Dockerized CI/CD, DNS, SSL/TLS and Cloudflare traffic for production services, plus Node.js and MongoDB backend features shipped end to end. I am looking for a cloud, DevOps or platform engineering role where reliability is the product.

A production learning platform with CodeRunner/Jobe grading services on dual Intel Xeon Gold 6430 servers, holding steady through real classroom load of 1,000+ concurrent users.
Cloudflare Tunnel and Tailscale for identity-based remote access, OpenWRT for VPN routing and firewalling, Workers deployed with Wrangler at the edge.
Placement and recruitment platform: containerized microservices behind a hardened API, JWT and role-based access, Redis caching on the hot endpoints, Nginx reverse proxy in front.
A RAG chatbot, GRU and regression forecasting, and a Solidity trust layer, shipped cross-platform in twenty-four hours. Runner-up and software track winner among 250+ participants.
Deployment and monitoring for concurrent online evaluations — backend communication tuned for low latency, bottlenecks traced and cleared during live sessions.
Centralized academic platform for student, faculty and admin roles — access-controlled APIs and schemas built for concurrent multi-role use.
An entire institution’s coursework, quizzes and automated code grading had to run on hardware in the building — not a managed cloud — and survive a thousand students logging in at the same minute.
A k3s cluster on dual Xeon Gold 6430 servers, hardware RAID and dual 10GbE. Moodle, CodeRunner and Jobe split into a containerized service topology with ingress routing and managed secrets, then Prometheus, Grafana, cAdvisor and Node Exporter wired in before the first class, not after the first outage.
1,000+ concurrent users held through peak sessions. Metrics drove scheduling and resource allocation decisions instead of guesswork, and grading workloads stayed isolated from the platform serving the pages.

Python, Bash, TypeScript, JavaScript, Java — plus Node.js and Express on the backend side.
MongoDB schema design and query optimization, MySQL, Redis caching.
Oct 2025 — Mar 2026
CI/CD workflows, containerized deployments and infrastructure automation with Docker and GitHub Actions. Owned DNS, domain routing, SSL/TLS and Cloudflare traffic management for production services, and debugged deployment, certificate and networking failures across production and intranet environments. On the product side: Node.js and Express features from data model to rollout, MongoDB query optimization, and JWT-based RBAC built from scratch.
2023 — present
A self-hosted Linux environment with Cloudflare Tunnel and Tailscale access, Zero Trust identity policies, OpenWRT networking, edge functions on Workers, and full container-level observability. Everything documented, everything reproducible.
