Social Network Platform

A full-featured social platform with profiles, posts, followers, groups, events, and real-time messaging — built entirely from scratch without any framework.

• Real-time chat via WebSockets
• Session-based auth with secure cookies
• Database migrations, follower & group systems
• Dockerised deployment

Code Keeper — CI/CD Pipelines

End-to-end CI/CD for a three-service microservices app: a self-hosted GitLab deployed with Ansible, and Terraform-provisioned staging and production environments on AWS, with a manual approval gate before every production release.

• Self-hosted GitLab + Runner, deployed via Ansible roles
• Infra pipeline: init → validate → plan → staging → approval → production
• App pipelines: build → test → scan → containerize (ECR) → deploy
• Protected branches, least-privilege IAM, no credentials in code

Cloud Design — Microservices on AWS

Designed and deployed a six-container microservices app on AWS with Terraform and ECS — secured with Cognito auth and HTTPS through CloudFront, auto-scaled, monitored, and built to be cost-effective.

• Modular Terraform: VPC, ECS, ECR, Cognito, CloudFront, monitoring, budgets
• Cognito JWT auth; databases & RabbitMQ reachable only inside the VPC
• CloudWatch logs, alarms & dashboard, plus budget alerts
• Cost-driven design: no ALB / NAT, SSM Session Manager instead of SSH

Localhost HTTP Server

A high-performance HTTP/1.1 server written in Rust using event-driven I/O. Supports CGI (Python), virtual hosting, session auth, and file uploads. Siege-tested at 99.5% availability with zero memory leaks and a stable 6.7 MB footprint under up to 5,000 concurrent connections.

Orchestrator — Kubernetes (K3s)

Deployed a six-service microservices architecture on a two-node K3s cluster (master + agent) provisioned with Vagrant, and managed end-to-end by a single orchestrator.sh script.

• CPU-based horizontal autoscaling (HPA, 1–3 replicas at 60%)
• Databases & billing service as StatefulSets with persistent volumes
• Credentials only in Kubernetes Secrets, manifests managed with Kustomize
• Custom images built from Debian and pushed to Docker Hub

Maze Wars — Multiplayer FPS

A multiplayer first-person shooter in Rust with 2.5D raycasting graphics, procedurally generated mazes, real-time UDP networking, server-authoritative state, and support for up to 10 concurrent players.

Ray Tracing Renderer

A realistic 3D rendering engine in Rust using ray-tracing. Renders spheres, planes, and cylinders with accurate lighting, reflections, and interactive camera controls — zoom, rotation, and viewpoint changes.

Deep in System

Full Ubuntu Server setup on VirtualBox — manual disk partitioning, SSH hardening, UFW firewall, user management, FTP server, MySQL, WordPress deployment, automated backups with cron jobs, and a complete security audit.

Real-Time Forum

A forum with real-time private messaging via WebSockets, post categories, filtering, and secure session auth — built entirely in Go and vanilla JS.

Play with Containers — Docker Compose

Containerized a microservices movie platform with Docker Compose — six custom-built images, a private network where only the gateway is exposed, persistent volumes, and automatic restarts on failure. Extended with a React frontend served by nginx, movie poster uploads, and Swagger UI docs.

CRUD Master — Microservices API

A movie-streaming backend of three Flask services on three Vagrant VMs: an Inventory CRUD API on PostgreSQL, a Billing service consuming orders from RabbitMQ, and an API Gateway routing between them — orders queue safely even while billing is down.

• Asynchronous billing via RabbitMQ message queue
• PM2 process management, OpenAPI docs & Postman test suite

IT College Room Booking System

Multi-role room booking platform for a college, built in an Agile team. Admin dashboards, conflict-detection algorithms, reporting, commenting system, and full responsiveness.

GraphQL Profile Dashboard

A personal stats dashboard querying the Reboot01 GraphQL API — visualises XP growth, skill distribution, audit ratios, and user levels with interactive charts.

0-Shell

A minimalist Unix shell in Rust using raw system calls — no external binaries, no bash. Implements echo, pwd, cd, ls, cat, mkdir, cp, mv, rm and more, inspired by BusyBox. Handles quoting, flags, and robust error handling.

Deep in Net

Built and configured multiple network topologies in Cisco Packet Tracer — static IPs, VLANs, routing, DNS, HTTPS, FTP, and full connectivity validation across complex multi-device networks.

Net-Cat

A re-implementation of netcat in Go — TCP group chat rooms with connection limits, timestamps, message history for new joiners, and graceful disconnection handling.

Wget Clone

A feature-complete Go implementation of wget — single file downloads with progress tracking, concurrent downloads, rate limiting, background mode, and full website mirroring.

AI Game Bot — Filler

A strategic game bot that analyses the board state and calculates optimal moves using heuristic evaluation — achieving an ~80% win rate against competing bots.

Smart Road Simulation

A traffic flow simulation modelling vehicles navigating intersections using concurrent goroutines — avoiding collisions, deadlocks, and race conditions while maximising throughput.

Lem-in (Ant Farm Pathfinding)

Finds the optimal set of non-colliding paths through a tunnel network to move ants from start to end in the fewest turns — custom max-flow / BFS implementation in Go.

Library Management System

A menu-driven library system in Java using OOP principles — LinkedList-based storage, member management, issuance tracking, book limits, and clean encapsulated architecture.
