Erzen Krasniqi

Product Engineer · Full-Stack Systems · AI Infrastructure

I build production software end to end — from data models, APIs, background jobs, and deployment infrastructure to polished, accessible user experiences.

My work spans AI products, digital health, public-sector systems, internal platforms, and open-source infrastructure. I do my best work on ambitious teams where engineers are expected to understand the problem, shape the system, and own the result from idea to production.

What I bring

  • End-to-end product ownership — turning ambiguous problems into reliable, maintainable products that ship.
  • Backend and platform depth — secure APIs, authentication, data modeling, queues, caching, storage, observability, and deployment.
  • AI-native engineering — model integrations, streaming workflows, agents, tools, MCP integrations, and provider-agnostic systems.
  • Engineering with product taste — performance, accessibility, thoughtful interaction design, and attention to the details users feel.

Selected work

The kind of work I am looking for

High-impact roles in product engineering, backend/platform systems, developer infrastructure, or AI products — especially with teams that value ownership, speed, technical judgment, and excellent user experience.

Based in Kosovo and always interested in building technically ambitious products with thoughtful people.
