I’m Emirhan — a systems architect and product engineer. If it’s complex, critical, or expected to carry a crowd, I’m the person you want owning it.
Scroll to beginPrecise in the hand, invisible in the background, impossible to ignore when it works.
I don’t just contribute to products. I own the architecture, the decisions and the outcome: from sub-millisecond APIs to platforms serving more than a hundred thousand people, ambitious ideas become production systems, and then better ones.
A cloud platform, from the first schema to the live dashboard.
Rebuilding the query layer cut data-retrieval latency by 30%.
The customer portal, provisioning and billing run on a relational model I designed, with Socket.io streaming live server metrics straight into the interface.
Open-source streaming and indexing, built to take the crowd.
Serving 100,000+ active users.
Redis-cached Fastify APIs answer in under a millisecond, extraction pipelines and transcoding queues work behind them, and the frontends hold 95+ on Lighthouse.
A university’s central system, where the data cannot be wrong.
Built for 5,000+ concurrent students, faculty and staff.
For Azerbaijan University of Technology: curriculum and registration, grading pipelines, an online exam engine, role-based access with TOTP two-factor, and live document editing.
Self-hosted files that understand what is inside them.
Semantic search, OCR and auto-tagging run on one background AI worker.
Chunked uploads with live progress, image compression on client and server, and an isolated updater agent for one-click or scheduled container updates, all in Docker Compose behind Nginx.
The small piece of open source that makes an interface feel finished.
A lightweight, polished marquee component for Nuxt.
