STATISTICAL ANALYSIS | DATA SCIENCE | AI AUTOMATION | 100% JOB SUCCESS | BUSINESS AND SURVEY ANALYSIS | Market Research and analysis Hey I'm Amy, thank you for visiting my page. I help businesses, researchers, and organizations maximize their spreadsheets into executive-level insights and automated systems. If you have data but don’t have the answers, or you have a manual process that is costing you time, those are the kinds of challenges i like. Whether you are a researcher with complex survey results or a business owner with spreadsheets you don’t want to look at, I can help you transform those numbers into actionable strategies. I specialize in high-stakes statistical analysis and custom automation that saves you hours of manual work. The clients I work with most often: 1. Academic researchers & PhD candidates: You have gathered your data but need expert SPSS analysis, hypothesis testing, regression modeling, ANOVA, and publication-ready reporting. 2. Business operations teams that need large, complex Excel datasets cleaned, organized and turned into dashboards or reporting systems 3. Operation managers and teams that want to automate their workflows using n8n, ClickUp, AI-assisted processes, or Asana without manual entry. 4. Survey designers looking to move beyond "vanity metrics" to understand the why behind consumer or patient behavior. 5. Health & Social Science firms that need predictive modeling (Regression, Clustering) to forecast trends and outcomes. I have worked across research, healthcare, business operations etc., to provide insights, automate processes and help clients move from disconnected spreadsheets and manual workflows to scalable systems and analytics. Some reviews from previous clients . . “𝗔𝗺𝘆 𝗶𝘀 𝗱𝗶𝗹𝗶𝗴𝗲𝗻𝘁, 𝘁𝗶𝗺𝗲𝗹𝘆, 𝗮𝗻𝗱 𝗮 𝗴𝗿𝗲𝗮𝘁 𝗰𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗼𝗿.

I design and manage Google Business Profile and review systems that make local and ecommerce businesses easy to find, trust, and choose -- without relying on backlink campaigns, technical website SEO, or generic content production. Most agencies treat reviews and GBP as separate, reactive tasks. I build governed systems instead: structured GBP optimization, automated review generation, response management, and policy-based compliance monitoring, so visibility and trust grow continuously rather than depending on one-off fixes. For over 15 years, my work has centered on GBP suspension recovery, review velocity systems, sentiment tracking, and local search visibility for single-location businesses, multi-location organizations, and ecommerce brands that depend on trust signals to convert demand. AI search visibility is part of how I think about discoverability today, since buyers increasingly check AI-powered search alongside Google and reviews, but it supports the core system rather than replacing it. This is not SEO agency labor. It is an operating system built for durability, scale, and measurable growth.

Whether you're exploring AI for the first time or trying to improve an existing system, the biggest challenge isn't building AI, it's building AI that actually works for your business. And worse still, many AI projects never deliver the value they promised because they're built around the technology instead of the people and processes they're supposed to improve. The result? → AI agents that break the moment real users go off-script. → RAG systems that hallucinate instead of retrieving the right information. → Automations that create more work instead of saving time. → Teams that stop using AI because they don't trust it. That's where I come in. The best AI implementations don't start with models or frameworks. They start by understanding how your business operates, identifying where people spend time making repetitive decisions, and then building AI around those workflows I help businesses build AI systems people actually rely on, whether it's AI agents, RAG pipelines, or an LLM-powered automation system that run in production. Startups and growing businesses hire me when they need intelligent AI systems that actually work: agents that execute multi-step tasks, RAG systems that surface accurate answers from their data, and automation workflows that eliminate hours of manual work daily. I work with startups, agencies, and service businesses that want to automate operations, improve customer experience, and unlock the value of their business data with AI. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⭐ CLIENT RESULTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ "Victor delivered a multi-agent RAG system in 3 weeks that cut our support ticket volume by 60%. Clean architecture, zero hand-holding needed." — SaaS Founder "Victor built an AI sales automation agent that now handles 80% of our lead qualification. ROI in the first month." - Ecommerce Client "Our internal knowledge base assistant went from concept to production in under 2 weeks. Highly recommend for any LLM project." — Tech Startup CTO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 WHAT I BUILD ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ → AI agents with tool calling, memory, and multi-step reasoning → RAG systems connecting LLMs to your documents, databases & APIs → Multi-agent orchestration systems (LangGraph, CrewAI, AutoGen) → AI chatbots for customer support, lead generation & onboarding → Sales automation: lead qualification, follow-ups, and booking flows → Internal AI assistants powered by your proprietary business data → Workflow automation integrating Slack, Notion, CRMs, and custom APIs → End-to-end LLM deployment: backend, infra, monitoring & evaluation ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚙️ TECH STACK ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🧠 LLMs: Claude 3.5 Sonnet | GPT-4o | Gemini | Mistral | LLaMA 🔗 Frameworks: LangChain | LangGraph | CrewAI | AutoGen | Haystack 🗄️ Vector DBs: Pinecone | Weaviate | pgvector | FAISS | Chroma 🐍 Backend: Python | FastAPI | Node.js | REST APIs | Webhooks ☁️ Cloud & Infra: AWS | Docker | Serverless | CI/CD pipelines 📊 Evaluation: LLMOps | Hallucination reduction | AI monitoring ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🧠 WHY CLIENTS CHOOSE ME ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✔ Production-first mindset. I build for scale, not just proof of concept ✔ Deep expertise across the full LLM stack: retrieval, orchestration, deployment ✔ Accuracy-obsessed, strong focus on reducing hallucinations in RAG systems ✔ Clear communication and structured delivery, milestone by milestone ✔ Free 30-min consultation to scope your project and recommend the right architecture If you're looking for an AI partner who thinks about your business before writing code, let's talk. 💬 Send me a message.
