At Wiveda GmbH, I developed across the workflow of a live automotive CRM serving 420,000+ users. I also built the dealer portal end to end as its sole developer, increasing weekly booked appointments from 2.75 to 20.5.
I built an LLM agent that negotiates prices with sellers over email, and worked on an AI voice-calling system whose CRM integration increased customer inflow by 50%. I also reduced critical reporting queries from 7–8 seconds to 2–3 seconds.
During my freelance work, I built React and Next.js frontends with Django backends and delivered Python data-collection projects for commercial clients. I was later rehired by Wiveda to bring my LLM integration and prompt engineering experience into production.
My projects include auction-platform integrations, scraping infrastructure, and an automated voice-calling engine. I work mainly with PHP, Python, and SQL, and have also built projects in Kotlin and Swift.
