Featured Systems & Engineering Projects
DeployServers
Automated Application Deployment Platform & Distributed Worker
A self-hosted PaaS platform orchestrating automated builds and container deployments. Features GitHub OAuth, push webhook interception, asynchronous BullMQ/Redis job queue processing, automated project-type detection (Node.js / Python), dynamic Dockerfile generation, and isolated container execution.
- ›Built asynchronous task queue with BullMQ and Redis for decoupled, reliable deployment jobs.
- ›Engineered automated runtime inspection to detect Node.js vs Python repos and synthesize optimized Dockerfiles on the fly.
- ›Integrated GitHub OAuth and raw webhook listeners to trigger instant zero-downtime rebuilds on git push.
React-Native-Pad (ReactNative Sandbox)
Browser-Based Isolated React Native Execution Sandbox
A cloud-hosted playground enabling users to write and execute React Native code directly in the browser without local SDK setup. User code runs within isolated Docker containers orchestrated by a custom Node.js reverse proxy, dynamic port allocation manager, Redis session tracking, and scheduled cleanup cron jobs.
- ›Engineered custom reverse proxy in Node.js using http-proxy-middleware with dynamic port pool management.
- ›Implemented strict container isolation using Docker with multi-stage builds to minimize image sizes and boot latency.
- ›Devised crypto-based client session hashing stored in browser localStorage for conflict-free container binding.
mini-git (Version Control from Scratch)
Lightweight Git-Like Version Control Engine Built in Python
An educational implementation of core Git internals built from first principles using plain Python and the file system. Demonstrates low-level content storage, commit snapshots, branch references, HEAD pointer resolution, and history traversal without relying on any external VCS libraries.
- ›Reimplemented Git's content-addressed object storage paradigm (`obj/`) for immutable commit storage.
- ›Constructed pointer-based branch architecture (`ref/branches/`) and HEAD pointer resolution.
- ›Implemented commit history log tracking (`commitRef`) and branch checkout mechanics that update pointers without data loss.
AI-PaperCorrection
End-to-End Automated Exam Assessment Platform
A production-grade full-stack platform for automated grading of handwritten and digital academic papers. Features a containerized FastAPI backend with PyMuPDF document rendering and assessment powered by Google Gemini multimodal vision API, delivered through a modern Next.js web interface.
- ›Developed high-throughput PDF processing pipeline converting student examination sheets into high-resolution imagery using PyMuPDF and Pillow.
- ›Integrated Google Gemini multimodal vision models for rubric-aware handwriting analysis and automated mark calculation.
- ›Designed full multi-container Docker Compose environment with container health checks and volume mounts.
AGENT_DID (Socratic Cognitive Tutor)
Stateful Multi-Agent Socratic Evaluation Framework
A stateful pedagogical multi-agent system built with LangGraph and LangChain. Implements an adversarial 'dumb student' agent that poses probing doubts exposing conceptual misunderstandings, coupled with an evaluation agent that computes a 0-1 understanding score and triggers corrective interventions.
- ›Constructed multi-agent cyclical state machine using LangGraph to guide multi-turn Socratic learning dialogues.
- ›Engineered automated understanding scoring logic extracting quantitative comprehension metrics from conversational interactions.
- ›Integrated Mem0 long-term memory for cross-session learner context retention and personalized concept reinforcement.
No-Code RAG Builder
Visual Workflow Editor for Retrieval-Augmented Generation Pipelines
An interactive node-based visual workflow editor enabling engineers and analysts to construct, configure, and execute Retrieval-Augmented Generation pipelines without writing boilerplate code. Connects Knowledge Nodes, Vector Retrievers, LLM Reasoning Nodes, and Output Targets.
- ›Built drag-and-drop pipeline composer connecting heterogeneous data sources to vector databases and LLM models.
- ›Decoupled graph serialization from execution runtime, allowing rapid pipeline iteration and instant testing.
- ›Designed separate decoupled microservices for the frontend canvas and backend pipeline execution.
NodeS3 Cloud Gallery
Private Cloud Vault with AWS S3 Pre-Signed Cryptographic Access
A full-stack cloud media vault designed with zero public bucket exposure. Features Node.js Express backend and React frontend utilizing AWS SDK v3 to generate time-limited cryptographic pre-signed URLs for direct, secure uploads and viewings.
- ›Enforced strict private S3 bucket configuration with all public access blocked at the IAM and ACL levels.
- ›Implemented pre-signed URL generation using AWS SDK v3 to offload heavy file transfers directly to S3.
- ›Designed responsive React gallery with grid selection, asynchronous uploads, and individual asset purging.
AlgotradeBackend
Real-Time Algorithmic Trading & Paper Trading Execution Engine
Real-time financial quantitative backend built with FastAPI, WebSockets, pandas, and SQLAlchemy. Features live market telemetry ingestion via yfinance, rolling moving average crossover backtesting (50/200 MA), real-time signal broadcasting, and a stateful `LivePaperTrader` execution engine.
- ›Constructed WebSocket streaming service for real-time market data broadcasting and trading signal emission.
- ›Implemented moving average crossover strategy (50/200 rolling window) with automated signal triggering.
- ›Built a stateful `LivePaperTrader` simulator managing cash reserves, position sizing, average execution prices, and trade logs.
