At Retenlins, I built IARA, a system of Python agents on WhatsApp for sales outreach, lead qualification, follow-ups, and reporting. Its SDR replies use Plan, RAG, Answer, and Review steps; testing reduced cost per conversation from US$1.51 to US$0.69.
I built the CRM with Next.js, ASP.NET Core, and PostgreSQL, releasing it 78 times over two months. In three weeks, weekly core actions rose from 96 to 415, and 205 of 209 CRM writes came through the agent.
I also coordinated programming and art direction for Sophie: Starlight Whispers, released on Steam in 2026. Before engineering, I worked in digital marketing and design, building websites and tracking sales funnels with Excel and VBA.
