You will get AI Agent Develop, API Integration, LangChain, AutoGen & Workflow Automation
Project details
In today’s fast-paced AI landscape, Businesses demand autonomous AI agents that can make decisions and execute workflows across systems in real time. That’s where I come in.
I specialize in building custom AI agents and tool-augmented LLMs using cutting-edge frameworks like LangChain, LangGraph, LlamaIndex, MCP, crewai, and AutoGen. From multi-agent research systems to customer support agents that integrate with CRMs and databases, I deliver tailored AI solutions that are both intelligent and scalable.
With a track record of building enterprise-grade AI systems deployed at scale (310K+ monthly interactions, $62M+ client value delivered), I bring not just technical expertise but also a strong business focus. My solutions are optimized for speed, reliability, and cost-efficiency, leveraging GPU acceleration, scalable cloud-native infrastructure, and best-in-class LLMOps practices.
Whether you need a research agent, a process automation workflow, or a code-generation assistant with evaluation harnesses, I’ll craft an AI solution that operates as your virtual teammate, autonomous, efficient, and ROI-driven. Let’s transform your workflows with intelligent agents that work for you.

Job Success
Ubauro, Pakistan - 12:33 am local time
⭐️ 56+ completed projects spanning full-stack, machine learning, and generative AI.
⭐️ 16 end-to-end projects: RAG, multimodal RAG, Agentic AI systems, vision-language fine-tuning
Most AI projects stall in the gap between a working notebook and something you can actually ship and maintain — no clean deployment path, no way to evaluate or monitor it.
Closing that gap is my focus.
I'm Zain — a generative AI application engineer. Not just the model. The entire stack:
✅ Agent Orchestration ✅ RAG pipeline ✅ Fine-tuned LLM
✅API ✅ containerization and Kubernetes deployment ✅ CI/CD pipeline
✅ Monitoring and observability that keeps it all healthy at scale.
━━━━━━━━━━━━━━━━━━━━━━
WHAT I BUILD FOR YOU
━━━━━━━━━━━━━━━━━━━━━━
🔷 RAG & agents — semantic search, reranking, memory, and multi-agent workflows with LangChain, LangGraph, and CrewAI over FAISS, Qdrant, Pinecone, and AstraDB.
🔷 Fine-tuning — adapting open vision-language and language models (LoRA / QLoRA / PEFT / SFT) to your data and domain, efficiently enough to train on accessible hardware.
🔷 Deployment & MLOps — Docker, Kubernetes, FastAPI, GitHub Actions CI/CD, Terraform, and AWS, with Prometheus / Grafana monitoring and LLM-specific tracing via Langfuse. Your AI ships reliably, scales automatically, and is observable from day one.
🔷 Multimodal systems — pipelines that combine text, PDFs, images, and audio using OCR, vision-language models (CLIP, Qwen2-VL, Florence-2, MAIRA-2), and Whisper.
━━━━━━━━━━━━━━━━━━━━━━
WHO I WORK BEST WITH
━━━━━━━━━━━━━━━━━━━━━━
→ SMBs, funded startups, and agencies who need someone who can both build a GenAI feature and get it deployed — a builder who ships, not just a notebook.
→ CTOs and technical founders who need a senior AI partner, not just a developer
I do not take every project. I take projects where I can make a real difference — where the work is technically meaningful and the client is serious about building something that lasts.
