I’m ready to launch a brand-new mobile application and, at the same time, breathe new life into an existing one. Your first responsibility will be to engineer the fresh app from the ground up—selecting the tech stack, designing the architecture, writing clean, test-driven code, and getting it live in the app stores. While that build is under way, I’ll also rely on you to add new features, boost performance, and eliminate lingering bugs in the current code-base so both products can evolve in parallel. Technical excellence alone isn’t enough, though. I want every engineering decision to align with a clear revenue path and solid growth strategy. Expect to contribute to the go-to-market plan, outline monetisation opportunities, and help shape partnership or user-acquisition tactics that make sense for the product’s niche. Deliverables • MVP of the new mobile app with source code and build pipeline • Updated version of the existing app, showing measurable performance gains and a resolved bug list • Concise go-to-market and monetisation brief (1–2 pages) • Full hand-off package: documentation, test cases, and deployment guides Acceptance criteria: the new app passes all agreed functional tests, the updated app shows quantified speed improvements, and the strategic brief is actionable without additional clarification. If you can blend hands-on coding with sharp business thinking, let’s talk timelines and milestones.
