I can help You!

During a free of charge discussion, let's brainstorm your idea to make your dream come true. Have a look on my professional portfolio applications.

Consultancy Presenter macOS app

Consultancy Presenter is a native macOS app built for consultants.

Its purpose is to eliminate the need to switch between dozens of windows during client presentations — browser, Keynote, notes, screen recording, chat. A single wrong move can reveal another client's confidential data on the screen.

Consultancy Presenter provides a single-window, local solution for this: a separate workspace per client, with every document, browser window and recording staying on your own machine.

Functions:

• Workspaces per client — full isolation, no mix-ups
• Document slots: quick access to HTML, URL and Markdown content
• Built-in browser (webview) for live demos
• Native macOS screen recording directly from the app
• Movable, resizable camera overlay on top of the presentation
• 100% local operation — no cloud, no external storage

Tasks: Full end-to-end development — from idea to working MVP. PoC creation, brainstorming, Product Brief, PRD, UX design, architecture planning and implementation. Personal project, as a solo developer, with an AI-assisted workflow.

Tech stack:

• Flutter UI framework, with a native macOS build
• Dart
• Native macOS platform integration (screen recording, webcam, filesystem)
• Specification-driven development (SDD) workflow, with AI-assisted coding
