Elmir Beširović

Full-stack engineer

Software engineer in Bosnia and Herzegovina. I build the whole thing: the frontend, the APIs, the database and the servers under it, and I stay after launch to keep it running.

Full-stack in Next.js and Node.js, Python and FastAPI for AI and automation work.

Work I take on

What I build

Real-time products

Live charts and P&L over WebSockets, and a panic button that reaches an ops console in seconds.

Products from scratch

Web and mobile apps from the first schema to production, and the infrastructure under them.

AI that does real work

LLM agents, RAG and workflows over real data, with a person checking where it matters.

AI on hardware

Photo kiosks that generate images on the spot and run unattended, updated over the air.
