What I do
One engineer for the whole system.
From the first workflow you want automated to a company-wide platform — designed, built, deployed and supported end to end.
AI agents & LLMs
Chatbots, support agents and document analysis — on cloud models or local LLMs when data must stay in-house.
Vector search & RAG
Search documents, people and products by meaning, not keywords — with embeddings and vector databases.
Machine & deep learning
Models for classification, forecasting and quality checks — trained on your data and wired into production.
Dashboards & data
Every KPI on one screen, pulled straight from your store, ad platforms, machines and internal systems.
Custom CRM & ERP systems
Software shaped around how your team actually works — with single sign-on, role-based access, onboarding flows and separate environments.

Full-stack web & mobile
