Proof, not promises.
Every learner graduates with deployed systems and public write-ups. Here's what you'll ship.
Three capstones, three levels
AI-Powered Multi-Tenant HRMS
A production-deployed, multi-tenant HRMS with org hierarchy, RBAC and audit logs — plus an AI HR assistant, embeddings-based smart search and workflow suggestions. Real infra, real data flows, live demo.
Explore Track 1Production-Grade Multi-Service Platform
The HRMS extended into a multi-service platform: Kafka event streaming, SAML SSO, Elasticsearch search and WebRTC video — fully Kubernetes-deployed, observable and load-tested at 10k concurrent users.
Explore Track 2Geo-Distributed Architecture Thesis
A distributed system you design from scratch, deploy across 2+ regions, chaos-test and load-test at 100k+ users — then defend before an engineering panel and publish as a public architecture write-up.
Explore Track 3Everything you'll build along the way
Production CLI Tool
A real command-line tool shipped through a proper Git workflow — branches, PRs and peer review.
Full Auth & Identity System
RBAC, email verification, JWT refresh, audit logging and Redis session caching.
Admin Dashboard Frontend
Role-based views, data tables, approval flows and real-time notifications wired end-to-end.
Distributed Notification System
Email + SMS + push via queues, with retry, dead-letter handling and delivery tracking.
Realtime Activity Feed
Kafka event stream + Elasticsearch audit log + WebSocket live push to the dashboard.
Production Infra on AWS
Terraform + Kubernetes with autoscaling, observability and blue-green CI/CD.
HTTP/2 Server From Scratch
A minimal HTTP/2 server on raw TCP sockets — every frame, header and stream state.
Raft Consensus Node
Leader election and log replication, verified on a 5-node cluster under failures.
AI Infrastructure Layer
Self-hosted vLLM inference, HNSW vector search, a multi-agent workflow and a cost dashboard.
