01 — About

From design to automation to AI

AI and automation engineer with 3+ years building automation systems, REST APIs and web applications. I've built WhatsApp API integrations, end-to-end lead automation pipelines and Wazora, a live WhatsApp automation platform for chatbots, campaigns and reminders.

I'm currently building LLM applications in Python, including a retrieval-augmented generation (RAG) app for querying large PDFs. I lead a team of 5+ and have delivered client projects across manufacturing, FMCG, recruitment and agriculture.

Still a designer at heart, I bring a strong visual, brand-focused sense to every project — and combine it with automation and AI to build solutions that don't just look great, but perform and scale.
