πŸ“‚ Featured Projects

πŸ”Ή MiniDbg β€” Linux Debugger in C++

C++17 β€’ Linux β€’ ptrace β€’ ELF β€’ x86-64

A lightweight Linux debugger built from scratch using ptrace, supporting software breakpoints, single-step execution, register inspection, memory access, and ELF symbol lookup.

Demonstrates low-level process control, CPU registers, executable formats, and debugging internals.


πŸ”Ή MiniRedis β€” Concurrent In-Memory Key-Value Store

C++17 β€’ Multithreading β€’ POSIX Sockets β€’ TCP/IP β€’ CMake

A Redis-inspired storage engine with a multi-threaded server, O(1) key lookup, LRU eviction, TTL expiration, AOF persistence, and crash recovery.

  • 50K+ operations/sec
  • Thread-safe concurrent access
  • RESP-style protocol parsing

πŸ”Ή SmartDoc AI β€” Document Intelligence & RAG Platform

Python β€’ FastAPI β€’ PostgreSQL β€’ pgvector β€’ LangChain

An LLM-powered document intelligence system combining dense vector retrieval with PostgreSQL full-text search and cross-encoder reranking.
