Logo & App Icon Design for Career Tech Startup (Government Transition)

I am launching Pivot, a career architecture tool designed by a government veteran to help public sector professionals translate their high-stakes experience into private sector roles. I am looking for a designer to create a clean, modern, and professional logo and app icon. This app is associated with my established coaching practice, "RJ Leadership Coaching, LLC." I want the new logo to feel like a "sibling" to my existing brand while maintaining its own distinct identity. Visual Context: Existing Brand: I have attached my current logo, RJ_Leadership_Coaching_Logo_128x128.png, which uses a seedling/sprout motif and a specific blue-to-teal gradient. The Goal: The new app logo should be an evolution of this brand; it needs to feel related but sophisticated enough to stand as a standalone tech product. It must be minimalist and highly legible as an app icon at small sizes. Deliverables: Vector source files (.AI or .EPS). App icon variations (optimized for mobile home screens). Web-ready formats (PNG, SVG). Black/White and full-color versions. Requirements: Portfolio demonstrating minimalist branding and app icon design. Ability to work in vector-based software (Adobe Illustrator). Experience in creating distinct "sub-brands" that complement a primary business.
