╚═══════════════════════════════════════════════════════════╝

Python AI engineer who builds end-to-end intelligent systems — from fine-tuning LLMs and designing RAG pipelines to deploying production FastAPI backends that handle real users. I care about things that actually work: low latency, correct retrieval, reliable APIs, and models that behave in production, not just in notebooks.

Currently finishing CS @ Bahria University (3.81 GPA, graduating June 2026). Based in Karachi, Pakistan. Available for remote roles.

Python · FastAPI · Gemini AI · PostgreSQL/PostGIS · JWT · Render · Supabase

An agentic platform for Pakistan's informal economy. Users describe a service need in natural language (Urdu, Roman Urdu, or English) — JUVO's multi-agent pipeline extracts intent, finds geographically nearby providers via PostGIS spatial queries, and creates a confirmed booking, all within a single conversational flow.

• Designed a multi-agent architecture: Intent Agent → Discovery Agent → Booking Service
• Built Hold-to-Lock (HTL) reservation system with 5-minute expiry and ACID database triggers to eliminate 100% of double-booking conflicts
• Implemented role-based JWT auth (user + provider), rate limiting, background task cleanup, and full Swagger documentation
• Deployed on Render + Supabase with Docker; full provider dashboard with analytics

Python · LangChain · Llama-3 (3B) · LoRA · MongoDB Vector Atlas · ChromaDB · RAG

Domain-specific legal AI assistant built on fine-tuned Llama-3 with a production-grade RAG pipeline.

• Fine-tuned Llama-3 (3B) using LoRA (r=32, α=64) on criminal law cases and legal statutes for improved legal reasoning
• Engineered a vector database on MongoDB Vector Atlas — 0.98 accuracy on past cases and legal statutes
• Production-level techniques: streaming responses, caching, rate limiting — query speed reduced to 200ms
• Chat and message management via LangChain memory components

Python · FastAPI · WebSocket · Computer Vision · Pose Estimation

Real-time fitness AI built during internship at Meta Frolic Labs.

• Custom computer vision pipeline with pose estimation algorithms — 98% accuracy in live exercise detection
• FastAPI backend with WebSocket integration for real-time data streaming at 0.3ms latency
• Performance analysis algorithm evaluating form quality and delivering corrective suggestions through a web interface — 40% improvement in feedback system effectiveness

Python · SpeechT5 · Transformer · Multi-speaker TTS

Speech synthesis system targeting the voice of Zia Mohyeddin, Pakistan's most celebrated literary narrator.

• Developed SpeechT5 transformer-based architecture with multi-speaker capabilities
• 25% improvement in naturalness over existing Urdu TTS solutions
• 92% user preference in blind listening tests for voice fidelity

Python · PyTorch · GANs · Transformers · Audio Processing

Research project: converting emotional tone in speech while preserving semantic content.

• Designed a hybrid GAN + Transformer architecture — Transformer vector embeddings carry semantic context; GAN learns the target emotion tone
• Achieved 62% success rate on neutral → happy emotion conversion
• Custom approach combining contextual sentence embeddings with adversarial training for audio emotion transfer

Python · Transformers · Fine-tuning · NLP

Fine-tuned a language model specifically for high-quality paraphrase generation — preserving meaning while altering structure and vocabulary. Trained and evaluated on custom paraphrase datasets.
