FAQ

iOS (Swift, SwiftUI, UIKit, Objective-C), Android (Kotlin, Jetpack Compose, Java), Flutter and React Native for cross-platform, and Smart TV (Android TV, WebOS). The team covers native development, cross-platform delivery and SDK architecture — all under one engagement.

Yes. The team has delivered fully native iOS and Android apps, cross-platform Flutter apps from a single codebase covering iOS, Android and Web, and React Native apps with native module bridges. If you need to choose between native and cross-platform, we will advise based on your product requirements, team situation and timeline — not based on what's easiest to build.

Yes. The team has managed app store submissions end-to-end — AppStore Connect, Google Play, and white-label deployments to 800+ stores. CI/CD pipelines with Fastlane, Jenkins and GitHub Actions are part of how the team operates. Release management, versioning, beta distribution and production rollouts are handled without drama.

Yes. The team has taken over existing iOS and Android codebases, refactored legacy architectures (MVP to MVVM, MVC to Clean Architecture), migrated apps between Flutter versions, and added test coverage to untested codebases. If your app has history, that is not a problem.

Media and streaming, FinTech and payments, healthcare, enterprise and SDK development, e-commerce and marketplace, and blockchain and Web3. Each domain brings different compliance, performance and integration requirements — and the team brings that context to every engagement.

Agencies give you a named developer in the proposal and a different one on the project — often junior-heavy, managed by an account lead you only hear from on billing day. With DMexec you engage directly with the developer doing the work, and Dimmy is involved as technical sponsor on every engagement. No account manager layer, no junior fill, no markup on markup. Senior-level output at 40–60% of typical agency rates.

Fixed monthly rate per developer — no agency markup, no recruiter fees, no hidden costs. Senior mobile developers are typically priced at a significant discount to equivalent Western-European or US agency rates. The rate depends on seniority, platform focus and engagement scope. Book a 15-minute call and we will give you a straight number within the first conversation.

Yes — all developers work remotely. The team is European-based, which gives meaningful US and AU timezone overlap alongside full European coverage. Daily standups, async-first communication, and direct Slack access mean there is no coordination lag. If your company operates in a specific timezone, mention it on the intro call and we will confirm overlap before any engagement starts.
