► RAG PIPELINES & KNOWLEDGE SYSTEMS :
Retrieval-Augmented Generation with vector databases (Pinecone, Weaviate, FAISS, ChromaDB). Enterprise search, document Q&A, and AI knowledge bases with source attribution.
► LLM FINE-TUNING & ALIGNMENT :
Custom model training using LoRA, QLoRA, PEFT. RLHF and DPO alignment for domain-specific accuracy and brand-safe outputs.
► VOICE AI AGENTS :
Speech-to-text and text-to-speech integration. Voice assistants for customer support, operations, and telephony with real-time response handling.
► AI SAAS PRODUCT DEVELOPMENT :
End-to-end product build: system architecture, API design, React/Node frontend, Python backend, deployment. From MVP to scalable production platform.

PROVEN RESULTS (Why Clients Trust Me) :
✓ $100,000+ earned on Upwork across 233 successful contracts
✓ 100% Job Success Score — every client satisfied, every project delivered
✓ 7,305+ hours of verified development work
✓ Top Rated status — consistently high feedback and on-time delivery
✓ Repeat clients who return for additional AI features and scaling
My clients are startup founders, product teams, and businesses who need AI built properly with clean architecture, real documentation, and zero handholding after delivery. I don't disappear after launch. I make sure it works in production the way it worked in development.
HOW I WORK :
1. REQUIREMENTS — I listen first. Understanding your business goal is more important than the tech stack.
2. ARCHITECTURE — I design the system before writing code. Scalable, documented, and production-ready.
3. BUILD — Weekly updates, transparent progress, demo-ready milestones.
4. DELIVERY — Deployed, tested, monitored, with 30 days post-launch support.
READY TO BUILD?
If you need an AI agent, a RAG system, a chatbot, a full-stack AI app, or a Python automation tool — send me your requirements. I respond within hours with exactly how I'd build it and how long it will take.
Let's turn your AI idea into a working product.
