We build complete software products — web, mobile, and the AI inside them.
QueUp is a senior software studio from Serbia. .NET and Azure on the backend, React and React Native up front, AI where it earns its place — delivered for US and EU clients, and for our own product line.
Both founders on every project. Senior engineers behind them.
Between the five of us, we cover the full lifecycle — architecture, backend, distributed systems, web, mobile, AI, release, iteration. No project managers relaying messages, no junior handed your codebase.
.NET, Azure, ETL pipelines, RAG agents at enterprise scale.
React, React Native, OpenAI integrations.
Node.js, Kafka, AWS & Terraform — systems peaking at 80M+ requests/hour.
10+ apps shipped to the App Store and Google Play, end to end.
Microsoft enterprise UI, OpenStreetMap contributor, spec-to-production owner.
Six things we do.
From whiteboard to production and app stores. One team owns the whole build.
Framework-era monoliths to cloud-native Azure — without stopping the business.
ETL, reporting, RAG agents, document automation — AI that does real work, in production.
Senior capacity inside your team for 6–18 months, B2B and remote.
Online stores for businesses without a tech team — set up, launched, and maintained.
A full MVP build in exchange for equity. 1–2 startups per year, selective by design.
If your project isn't one of them, we'll tell you on the first call.
Proof, not promises.
In their words.
“BaitulMal has transformed how we manage donor funds and track expenses across multiple projects. The reporting features have saved us countless hours when preparing for audits.”
BaitulMal
A live fintech platform for non-profits: transparent, real-time donation tracking and financial reporting. We know the distance between an idea and a live product — because we've crossed it with our own money and time.
