Senior AI Architect | AI Agents, Chatbots, n8n & SaaS MVPs
AI support copilot (RAG) for SaaS. An AI copilot inside a B2B SaaS product that answers customers from the company's own docs, changelog and solved tickets (RAG), with guardrails, quality tests and a hand-off to the support team when a person should step in. Result: 60% of routine tickets taken off the support team's desk, instant answers 24/7, and live five weeks from kick-off. Fintech MVP: live in under 2 months. A fintech start-up's MVP, scoped, designed, built and shipped to real users in under two months on a fixed price and date: sign-up, onboarding, the core money flows, admin and analytics. Polished enough to raise on, and now live and raising. Two-sided marketplace SaaS. A multi-tenant marketplace SaaS, rebuilt after an earlier build buckled under real usage: each customer's data kept separate, Stripe Connect billing on both sides of the market from launch, role-based dashboards, admin tools and a public API, with automated releases and monitoring. Set up from day one to grow without another rebuild. Voice AI job interviewers. Voice AI agents that run full spoken job interviews for a recruitment client: a clear voice, real-time turn-taking and follow-up questions that adapt to each answer, then structured scores, transcripts and summaries for the hiring team. Delivered A to Z: conversation design, a low-latency speech pipeline, the interview logic with guardrails, and the web app for candidates and recruiters.
