Cover image for Marketing Assistant Bot
As part of

Marketing Assistant Bot As part of my work in AI-driven automation, I built a Marketing Assistant Bot using Relevance AI to address a major challenge in customer engagement: inefficient lead handling and inconsistent follow-ups. Businesses often struggle with manually qualifying leads, responding to competitor comparisons, and guiding potential customers through the sales funnel. The lack of automation resulted in lost opportunities, delayed responses, and high drop-off rates. To solve this, I developed an assistant on Relevance AI

Cover image for Ria Braids Studio — Luxury

Ria Braids Studio — Luxury Brand Website A fully responsive, motion-designed website built for Ria Braids Studio, a braiding salon serving Royse City and Dallas, Texas. The brief called for a luxury aesthetic that matched the brand's existing visual identity — warm rose, coral, and gold tones extracted directly from the client's logo and marketing materials. Key features: Fixed glassmorphism navigation with mobile hamburger menu, animated hero section with twinkling star field and rotating SVG badge, scroll-triggered reveal animations throughout, service cards with hover micro-interactions, three-tier pricing layout, a step-by-step booking flow, and a contact form that pre-populates and opens WhatsApp for instant client communication. Design approach: Paired Cormorant Garamond (luxury display) with DM Sans (clean body copy) to balance old-world elegance with modern readability. Custom SVG braid-pattern dividers echo the brand's craft. All motion respects prefers-reduced-motion for accessibility. Tech: Vanilla HTML, CSS, JavaScript — no frameworks, no dependencies. Fully self-contained single file.
