[FOR HIRE] Senior AI/Product Engineer | 16+ yrs | SaaS, mobile, admin systems, payments & automation

I’m Dimitar Jilanov, a senior software engineer / AI product architect with 16+ years of experience and 147+ delivered projects.

I build production software end-to-end — not just frontend screens or LLM API calls, but the backend, database, admin panel, billing, permissions, documents, integrations, queues, deployment, and support workflows that make a product usable by real customers.

A senior engineer to untangle, stabilize, or extend an existing product.
