I help businesses create custom AI chatbots, AI assistants, and RAG-powered knowledge systems that deliver accurate, context-aware answers using real company data such as PDFs, SOPs, help centers, websites, CRMs, ticketing systems, and SQL databases.
My focus is not just on making a chatbot respond. I build solutions designed for accuracy, reliability, scalability, and real business use.

✅ AI Chatbot & AI Assistant Solutions I Can Build:
● Customer support chatbots for websites, apps, and WhatsApp
● Internal company assistants for HR, SOPs, and employee helpdesks
● Document chatbots for PDFs, manuals, contracts, and policies
● Knowledge base and FAQ automation
● Email and ticket summarization assistants
● Database-aware chatbots that answer from structured data
● AI assistants connected to APIs, CRMs, and internal tools
✅ Core Expertise:
● RAG architecture
● LangChain and LlamaIndex
● OpenAI API integration
● Embeddings and vector search
● Pinecone, Weaviate, FAISS, and Chroma
● Hybrid search and re-ranking
● Prompt engineering and context optimization
● Hallucination reduction
● RAG evaluation and monitoring
● LangSmith, Langfuse, and performance tracking
I design chatbot systems for accurate retrieval, relevant answers, and stable production performance. This includes optimizing chunking, context selection, retrieval quality, and output evaluation to improve accuracy and control costs over time.
Clear communication and regular progress updates are always a priority. I build practical, maintainable AI solutions aligned with real business goals.

Hi 👋 I'm Vlad, AI developer with 10+ years of experience in engineering. Top Rated on Upwork, $100K+ earned, 2,900+ hours logged.
Sound familiar?
- Your team spends hours on tasks that could run automatically
- You tried an off-the-shelf AI tool - it doesn't fit your workflow
- You have a great product idea with AI at the core, but don't know where to start

If any of these sound like your situation, here's what I've built for clients in exactly that spot:
💡 AI financial assistant for WealthFluent (Fintech) - Built on Amazon Bedrock + Claude Sonnet. The assistant handles 100% of new user onboarding through conversation, explains portfolio data in plain English, and stays fully compliant with financial regulations.

💡 AI goal management coach (Productivity SaaS) - Personal coach PWA built in 3 months. AI breaks goals into milestones, sets reminders, tracks progress. Result: 50% faster task execution for users.
💡 AI platform for insurance brokers (InsurTech) - Modernized the UX of an AI-powered broker tool. Saved 1,500+ hours of broker time annually. Redesigned 10+ core workflows, integrated Stripe credit management and document previews.
What I build:

- AI agents that execute multi-step workflows autonomously
- RAG systems that let AI answer from your company's knowledge base
- Generative AI features embedded into SaaS products
- AI-powered onboarding, support, and automation flows
Tech stack:
OpenAI, Anthropic Claude, LangChain, LangGraph, Amazon Bedrock, AWS, Next.js, React, Node.js, Python, PostgreSQL, Stripe
Industries: FinTech, EdTech, InsurTech, Healthcare, Manufacturing, Logistics
Every project starts with: what problem costs you time or money right now? Then we build exactly what's needed - prototype first, production-ready fast.
