I’m Wania, a graphic designer and website developer based in Ontario - Canada, who has spent the last 6 years turning founder-daydreams into revenue-generating visuals. My logos live on 3 continents, my Shopify builds have helped DTC labels hit six-figure months, and one packaging redesign I shipped last year lifted in-store sales 42 % (ask me for the case study)... What I can do for you: Brand Identity that sticks – logos, colour systems, packaging & pitch decks that feel like “you” before the customer reads a word. Ads & social creatives – thumb-stopping graphics that cut CPC up to 31 % in recent campaigns. Web homes that sell – WordPress | Shopify | Squarespace | Wix, all mobile-first, SEO-ready, and pagespeed-green. Funnels & landing pages – wireframes to launch, engineered for conversions, not just compliments. I still remember the moment the first client told me her Shopify store crossed $100 k after the rebrand we launched on a Tuesday night. That single screenshot turned my freelance into a Six-year obsession with design that moves the needle. Today I split my time between Toronto cafés and Notion boards, building identities, packaging and websites for founders who refuse to look generic. Whether it’s a granola label that jumps off Whole Foods shelves or a landing page that out-converts the founder’s own pitch deck, every pixel I ship is backed by user research, speed tests and at least three cups of Canadian maple coffee. If you’re after a partner who will challenge your brief, send you text at midnight, and hand over a brand manual your future designer will thank you for - let’s chat... menos -
