I help SMB turn manual workflows into automated solutions with AI/LLM intelligence I have 7+ yrs of deep tech experience and use JS/TS, NodeJs, React, Playwright, Next, MERN, together with OpenAI GPT-5, Claude Opus 4.6, Gemini and many more LLMs I can dive into you business processes, analyze it and suggest a tech solution which will be a) cost effective, b) scalable For example I archived these results: - HealthCare domain: made patient data collection autonomous by 98.61% and clinic fired 2 of 3 receptionists - Ecommerce: cutted $15k monthly expenses by adding automated invoice fullfillment - EdTech: saved $200k/mo (analytics departament budget) by creating business inetelligence tool using RAG, and OpenAI I do not use Upwork too often but we can talk and see if we are a good fit for each other.
