I work across the full range of presentation and marketing collateral — pitch decks, investor presentations, board decks, sales materials, one-pagers, brand guides, lead magnets, case studies, and more. If it needs to look sharp and communicate clearly, I can build it.

High-profile work includes brands of Kevin Durant and Manny Pacquiao, and materials presented to international royal families.
