Building AI automations & agents that actually ship

I build AI automations, chatbots, and web apps for startups and small businesses — shipped in days, not months, and run entirely over text. No calls.

What I build

Three things I do end-to-end — scoped, fixed-price, and shipped fast.

01

RAG Chatbots & AI Agents

Chatbots and multi-step agents trained on your own docs and data — accurate, tool-using, and guarded against hallucination. Built with LangChain, vector DBs, and Claude/OpenAI/Gemini.

02

Workflow Automation

Lead capture, CRM sync, notifications, error logging — anything repetitive that eats your day. Wired together reliably with n8n.

03

Web Apps & APIs

Full-stack apps and production APIs with auth + database — FastAPI, React, Supabase, Dockerised and deployed. From idea to live URL, fast.

Problem

Teams drown in repeated questions that are already answered somewhere in their docs.

Solution

A Retrieval-Augmented chatbot that answers from company documentation using semantic search, with strict guardrails against out-of-domain hallucination.
