Based in Sofia, Bulgaria, I have been a web designer and developer for more than ten years. I take pride in my work and I enjoy it.

I build premium brand identities and brand identity systems for beauty, wellness, F&B, lifestyle, and product-led brands that need to look consistent, credible, and ready for their next stage. My work goes way beyond a logo or a visual refresh. I help brands define the structure behind the identity, so packaging, website, social content, sales materials, product lines, and vendor files feel like they belong to the same brand. I can help with: • Premium brand identity and visual identity systems • Luxury branding and rebranding • Brand identity systems for beauty, wellness, F&B, and lifestyle brands • Packaging direction and multi-SKU packaging logic • Strategic Brand Audits before redesign or rebrand • Brand Direction Blueprints before identity, packaging, website, or launch • Brand guidelines, usage rules, and vendor-ready documentation My process is structured and asynchronous. No unnecessary calls. No vague exploration. No endless design guessing. For existing brands, I usually start with a Strategic Brand Audit. This identifies what is misaligned, what should be preserved, and what needs to change before redesign, rebrand, or scale. For new or early-stage brands, I start with a Brand Direction Blueprint. This defines the positioning, perception, visual direction, and decision rules before execution begins. For full identity projects, I build complete brand identity systems through my dedicated service The Vault. This can include logo architecture, typography, color, packaging logic, layout systems, digital standards, brand guidelines, and structured handoff files for teams and vendors. Offer Structure I do not work hourly. I work through fixed-price engagements that define the right level of work before execution begins. Premium Perception Audit — $680 A focused visual perception audit for brands whose product, service, or offer is stronger than the way the brand currently looks online. I review the visible customer-facing layer across website, social presence, visual identity, product presentation, and key touchpoints. Strategic Brand Audit — $1,200 A detailed 24–32 page diagnostic before redesign, rebrand, or scale. It identifies what is misaligned, what should be preserved, and what needs to be refined or rebuilt before investing in execution. Brand Direction Blueprint — $2,000 AA strategic, visualized 24-32 page direction phase before identity, website, packaging, or rollout work begins. It defines positioning, perception, visual alignment, hierarchy, brand behavior, and decision logic before execution. Brand Identity Systems — The Vault — from $6,800 A full brand identity system built for premium and luxury-led brands that need consistency across packaging, digital, content, teams, vendors, and customer-facing touchpoints. Scope depends on product range, packaging needs, digital requirements, and rollout complexity. My experience includes brand work for beauty, wellness, food and beverage, hospitality, technology, supplements, and premium service brands, with past projects connected to companies such as Coca-Cola, Henkel, Victorinox, SAE-REN, VKA, Smile Rooms, Sports Timing Systems, Accolad, and Tame Nutrition. Strong fit if you need: • a premium or luxury brand identity • a rebrand before growth or launch • packaging and brand consistency across SKUs • a brand system your team and vendors can follow • clear direction before spending more on design Not the right fit for quick logo-only tasks, low-budget design requests, or projects where direction will be chosen by committee without a clear decision-maker. If your brand needs to look more consistent, premium, and credible across every customer-facing touchpoint, send me the details and I’ll recommend the right starting point. — Mariya • mariya.design Send me your brand detail. I’ll review your brand and recommend the right starting point.
