Pop-Up Engineering
Software & Engineering Studio

We design and ship software that works in the real world.

Pop-Up Engineering LLC is a software and engineering studio. We build native mobile apps, web applications, and data systems — taking an idea from first prototype through to the App Store and production infrastructure.

Start a project What we do

What we build

End-to-end engineering across the surfaces a modern product actually needs.

Mobile & iOS

Native Swift and SwiftUI apps, including Bluetooth and hardware integration, built to Apple’s guidelines and shipped through TestFlight to the App Store.

Web Applications

Fast, accessible front ends in React and TypeScript, backed by clean APIs — from marketing sites to full product dashboards.

Data & Quantitative Systems

Real-time data pipelines, trading and analytics dashboards, and backtesting tools — systems where correctness and latency matter.

Cloud & Infrastructure

Deployment automation, CI/CD, and cloud infrastructure that keeps releases boring and uptime high.

Architecture & Review

System design, technical due diligence, and code review to de-risk a build before — and after — it ships.

Prototyping & MVPs

Rapid, validated prototypes that turn an idea into something you can put in front of real users quickly.

About the studio

Pop-Up Engineering LLC is an independent software and engineering studio based in Media, Pennsylvania. We partner with founders and teams who need working software built well — not a deck, and not a demo that falls over on contact with real users.

We work across the full stack: native mobile, web, data infrastructure, and the cloud that runs it. Every engagement is built to be tested, maintained, and handed off cleanly.

How we work

Small, senior, and accountable. You work directly with the people writing the code.

Verified, not assumed — changes are exercised and reviewed before they’re called done.

Clear scope, clear handoff, and code you own outright.
