Mobile application development
iOS and Android, both ways: fully native apps in Swift and Kotlin, or cross-platform products in Flutter. We recommend the approach that fits your product — and deliver app-store-ready polish either way.
Software development agency
We engineer software people rely on.
O.P. Technologies designs and builds mobile, desktop and web applications — from first idea to production, with the craft of a product team and the discipline of engineers.
About us
Small team. Serious experience.
O.P. Technologies is a software development agency based in Kanjiža, Serbia. Over the years we have worked with clients worldwide, successfully shipping products across industries and platforms — software that is still in production, still growing, and relied on by people every day.
We build with modern, cutting-edge technology and treat every engagement as a real partnership: we contribute ideas, challenge assumptions and propose features — not just deliver tickets. Communication stays clear and fully transparent from the first call to long after launch. No hand-offs, no layers of account managers — the people you talk to are the people who build.

Real AI, in real products.
We build production AI features on top of the world's leading models — and we know where they create real value, because we ship them in our own products first.

LLM-driven translation, search, content understanding and automation — embedded into real products and engineered for reliability, latency and cost.
-
Custom AI systems
Purpose-built pipelines on top of leading foundation models, shaped by domain rules, guardrails and evaluation until the output fits your business — not the other way around.
