AI & Machine Learning Developer — B.Tech AI & Data Science (Final Year)

I build and ship production-grade AI systems end-to-end: generative AI pipelines, LLM fine-tuning, speech synthesis, and computer vision — optimized for constrained consumer hardware (6GB VRAM GPUs, Raspberry Pi edge devices). Every project here is independently built, documented, and deployed.


LLM & RAG

Gemma 3-1B Fine-Tuning

Fine-tuned Google’s Gemma 3-1B for Python code generation using QLoRA on a 6GB GPU. Achieved ~60% memory reduction vs full fine-tuning. Published on Hugging Face as GGUF.

RAGv2 — Offline Retrieval-Augmented Generation

Privacy-first local RAG with parent-child chunking, FAISS vector search, and IBM Granite 350M LLM — all running under 2s latency on consumer hardware with zero cloud dependency.

Speech & Audio AI

Qwen3-TTS GPU Suite

GPU-accelerated markdown-to-speech using Alibaba’s Qwen3-TTS. Voice cloning + 9 preset speakers, SDPA attention, bfloat16 — all running locally on an RTX 3050.

Whisper Dictate

Push-to-talk speech-to-text daemon for Wayland using OpenAI’s Whisper. Hold a hotkey, speak, release — transcription appears in any focused application. 100% local.

md2voice

Documentation-to-audio pipeline that uses Cerebras AI to rewrite technical docs into conversational text, then synthesizes speech via edge-tts or Piper TTS.

Computer Vision & Multimodal

Driver Drowsiness Detection

Real-time drowsiness detection using custom YOLOv11m-cls classification with dual-threshold temporal logic. Achieves 96.4% mAP@50 with multi-modal visual/audio/OS alerts.

Privacy-first semantic search for local image and video collections. Uses Qwen3-VL-Embedding-2B (2048-dim) with ChromaDB for sub-100ms vector lookups. No cloud APIs.

Guides & Tooling

llama.cpp Guide

Comprehensive guide for running LLMs locally on Windows using llama.cpp with various hardware backends (CUDA, Vulkan, Metal, CPU).
