I build small, focused, hands-on demos that turn abstract backend concepts — authentication, WebSockets, GraphQL, RPC, cloud deployment — into something you can click, break and understand. This site is my live playground for students, workshops and interviews.
Basic Auth, API Keys, JWT, OAuth 2.0 — with real request traces.
WebSockets, SSE, pub/sub patterns for chat, dashboards, IoT.
REST, GraphQL, JSON-RPC, gRPC — when to use which, with trade-offs.
Oracle Cloud, nginx, systemd, HTTPS, CI/CD — from laptop to production.
Python (FastAPI, Flask), async I/O, testing, clean architecture.
1-on-1 mentoring, college workshops, bootcamps — live, hands-on.
Compare Basic Auth, API Keys and JWT tokens side-by-side. Interactive diagrams show exactly which server code runs on each request.
NEWOne server exposing the same chat over WebSockets, GraphQL and JSON-RPC. Watch packets fly and see which lines of Python execute.
NEWRESTful blogging platform with users, posts, and comments. Bcrypt-hashed passwords, JWT auth, SQLAlchemy ORM, and an animated request-flow walkthrough.
I run live sessions on APIs, cloud & backend engineering. Ping me on WhatsApp or LinkedIn.
