Hi! My name is Lex (short for Alexander) This year alone, I’ve helped more than seven companies solve one of the toughest modern challenges — using their private data securely without exposing it to third-party APIs like OpenAI or Google. As a Secure AI & RAG Specialist, I design automation systems that run entirely within your private infrastructure — on-premise or in your private cloud — ensuring full control over data, compliance, and performance. Case Study (FinTech Client): A funding platform needed to automate document summarization and reporting across thousands of sensitive files. Using public AI wasn’t an option due to strict confidentiality and API costs. Solution: • Deployed a self-hosted open-source LLM and Vector Database within their servers. • Built a secure RAG pipeline indexing 10,000+ internal documents (reports, manuals, support tickets). • Delivered a hybrid Web & Office 365 interface for 50+ team members — instant, accurate answers from their own data, fully tenant-isolated. Results: • 100% data privacy and GDPR compliance. • ~65% reduction in manual document search and analysis. • $15,000+ monthly savings on API usage and manual work. • Faster, data-driven decisions across departments. This is what Secure Business Automation means — not just protecting information, but unlocking the hidden value in your own data to drive efficiency, reduce costs, and accelerate growth. With over 16 years in software development and CTO-level experience, I deliver turnkey AI and web solutions — from secure RAG architecture to user-friendly interfaces. Core Services: • Private AI & RAG Development — full pipeline from data vectorization to self-hosted LLMs. • Intelligent Automation — AI agents and internal workflow orchestration. • Secure Web Solutions — full-stack apps, dashboards, and chat interfaces. • AI Consulting & Architecture — helping you choose the right stack and build for scale. If you want to leverage AI safely and strategically — let’s talk. Your first consultation is free, and you’ll walk away with an expert view on what’s possible, what’s secure, and where the ROI begins.
