📝 BIO / OVERVIEW I build AI that works for you, autonomously. And I build it on a foundation of rigorous data science. I'm a Top-Rated AI/ML Engineer specializing in agentic AI systems, autonomous agents that plan, reason, use tools, and act without constant human input. With 6+ years of professional experience, MIT and IBM certifications, a Distinction in ML from the University of London, and a Letter of Commendation from the London School of Economics for scoring among the highest marks in the world in Data Science and Business Analytics, I sit at the intersection of two disciplines that are rarely combined well: agentic AI engineering and data science. Most agent builders don't think statistically. Most data scientists don't build agents. I do both, and that's what makes the systems I deliver more reliable, better scoped, and genuinely production ready. 🔧 What I Build Autonomous AI Agents Multi-agent pipelines using LangChain, LangGraph, CrewAI, and AutoGen. Agents with memory, planning, tool use, and reflection loops that actually run in production, not just demos. RAG & Knowledge Systems End-to-end Retrieval-Augmented Generation pipelines with vector databases (Pinecone, Weaviate, FAISS, ChromaDB), smart chunking, hybrid search, and re-ranking. Your LLM, grounded in your data. AI Workflow Automation Intelligent automations connecting LLMs to your business stack via n8n, Zapier AI, and Make. Lead enrichment, document processing, auto-reporting: AI wired into your existing tools. LLM Fine-Tuning & Deployment Domain-specific fine-tuning using LoRA, QLoRA, and PEFT on Hugging Face. Model evaluation, benchmarking, and scalable deployment on AWS, Azure, and GCP. Data Science & Predictive Analytics The foundation under everything I build. EDA, feature engineering, predictive modeling, statistical analysis, A/B testing, and BI dashboards. I work across industries to surface decisions, not just charts. 🎯 Why Clients Choose Me Systems thinker: I architect the full pipeline across data, retrieval, orchestration, and deployment. Not just a notebook. Data-grounded agents: My DS background means the agents I build are statistically sound, not just prompt-engineered. Production-grade delivery: Clean, documented, deployable code with real performance metrics. Top-Rated on Upwork with 6+ years of real-world AI/ML delivery across industries. MIT & IBM certified. Distinctions in Machine Learning, University of London. Letter of Commendation from the London School of Economics for ranking among the highest marks worldwide in Data Science and Business Analytics. 🛠️ SKILLS AI Agents & Orchestration LangChain, LangGraph, CrewAI, AutoGen, OpenAI Assistants API, Semantic Kernel, Agent Memory & Tool Use RAG & Vector Systems Pinecone, Weaviate, FAISS, ChromaDB, LlamaIndex, Hybrid Search, Re-Ranking, Document Chunking LLM Fine-Tuning & Generative AI LoRA / QLoRA, Hugging Face Transformers, PEFT, RLHF, GPT-4o, Claude, Gemini, Mistral, Llama, Prompt Engineering AI Workflow Automation n8n, Zapier AI, Make (Integromat), API Integrations, Event-Driven Pipelines Data Science & ML Python, Scikit-learn, PyTorch, TensorFlow, XGBoost, LightGBM, Pandas, NumPy, Statistical Modeling, A/B Testing, SPSS Data Visualization & BI Tableau, Power BI, Matplotlib, Seaborn, ggplot2 Cloud & Infrastructure AWS, Azure ML, GCP Vertex AI, SageMaker, Snowflake, Docker, FastAPI, PostgreSQL, MongoDB, Apache Spark 💬 CLIENT TESTIMONIALS "Collaborating with Zainab was outstanding.

I build BigQuery warehouses, dashboards, and increasingly the AI and LLM layer that goes on top of them. For the last six years I've consulted for companies ranging from big-box retailers to Y-Combinator tech startups to help them get out from under manual reporting and scattered data. Most recently I've been building RAG systems and LLM observability for industrial SaaS applications, alongside the BigQuery, executive dashboards, and data engineering work (ETL) that has been my main lane for years. What I help clients build: • RAG and LLM systems. Production RAG over your business data (Claude, Gemini, GPT, vector stores), prompt and retrieval evaluation, dashboards for LLM cost, latency, and accuracy, and agentic workflows that connect tools to action. • BigQuery warehouses and ETL. Schema design, partitioning, cost cleanup, plus Python pipelines that ingest from Quickbooks, Stripe, GHL, HubSpot, GA4, Shopify, Filevine, and a long list of custom APIs. HIPAA-compliant when it needs to be. • Dashboards that actually get used. Looker Studio, Metabase, and ThoughtSpot (avoid PowerBI and Tableau like the plague). I always prototype the dashboard, so you see the end result first, we don't build pipelines you don't need, and I can give you a fixed-price quote (most freelancers will never give fixed-price quotes). • Internal tools and automations. Cloud Functions, Cloud Run, Slack and email integrations, Stripe billing, scheduled syncs. Things that should just run quietly in the background and stop being someone's manual job. A few things to know about working with me: I've hired freelancers on Upwork myself, so I know the difference between someone who hides behind their service and someone who moves the business forward. I write SQL and Python the next engineer can read without a guide. I'll tell you when the fancy version of a thing isn't worth building. I prefer working off real data and screenshots over abstract requirements docs. I have adopted AI tools that help me to complete data projects in 7 days by myself that used to take me 12 weeks with a small team.

As a dynamic data expert with a proven track record, I specialize in end-to-end data solutions across data engineering, data warehousing, and business intelligence (BI) domains.

I create robust data pipelines to connect ad performance with customer behavior for effective reporting and campaign optimization. • AI/LLM-based Reporting: Skilled in creating natural language querying (NLQ) systems and reporting solutions built on Large Language Models (LLMs) to make data accessible to non-technical users. ADVANCE AND SPECIALIZED SKILLS: • Serverless Computing: Proficient in architecting cloud-native serverless systems leveraging managed services to build scalable, resilient, and cost-efficient data and application workflows. • API Integration: Expert in consuming, managing, and integrating APIs using Python to handle challenges like rate limiting, OAuth authorization, pagination, and incremental data loading. • Data Governance and Quality: I implement data quality checks and data governance frameworks to ensure data integrity and reliability. • LLM and Generative AI: I am skilled in building LLM-based reporting systems and enabling natural language querying (NLQ) to make data accessible to non-technical users. WHO I WORK WITH: Founders building AI powered products who need someone who's shipped before. Startups scaling from prototype to production with real users and real edge cases. Businesses drowning in manual data collection or repetitive workflows. Teams that tried building it themselves, hit a wall, and need someone to fix it. HOW I WORK: Scope Call — I understand your problem, constraints, and timeline. I'll tell you honestly if I'm the right fit. Architecture Doc — Before writing code, I define what we're building, why, and how. You get a clear plan with milestones. Build in Sprints — 1-2 week cycles.
