I designed the complete logo identity for Prestige Communications, a digital marketing agency in Athens. The mark is a bespoke 'Couture P' monogram — a refined custom letterform that hides a chat-bubble silhouette inside its curve, a quiet nod to the heart of what Prestige does. The system pairs the monogram with an Orpheus Pro 'PRESTIGE' wordmark and a tight-tracked 'COMMUNICATIONS' sub-line for editorial presence and quiet authority. The brand is built on four pillars — Elegant, Influential, Bespoke, Trusted — and a deliberately restrained palette: Prestige Gold (#BF9B5C), Deep Black (#000000), and Soft Cream (#F5F0E8), with Poppins as the body companion typeface. A full logo suite — dimensional, gradient, and solid variants across horizontal, stacked, and symbol-only lockups in light and dark — was delivered in AI, EPS, PDF, SVG, and PNG, alongside in-context mockups (gold-foil embossed business cards on black cotton stock, brushed-brass signage on walnut, and red-carpet event activations).

I designed and built savage.design, the flagship site for my freelance creative studio working out of a mountain village in Greece. The visual centerpiece is a THREE.js shader-driven fractal orb that persists across PJAX page transitions, paired with a custom WebGL 'inversion lens' hover effect on portfolio cards built on a shared renderer and an LRU texture cache. Architecture: vanilla PHP (no framework) with a custom PJAX router that enforces per-page init/cleanup contracts to prevent listener leaks and CSS contamination, GSAP and Lenis for motion and smooth scroll, and a PHPMailer-backed quote API with CSRF, honeypot, session rate-limiting, and GDPR consent. The site ships in 7 languages (EN / EL / DE / FR / ZH / DA / ES) with clean URL rewrites, hreflang alternates, language-aware Google Business reviews, and a comprehensive JSON-LD graph (Organization, CreativeWork, Service, AggregateRating, Review). Accessibility is WCAG 2.2 AA: skip link, modal focus traps, route announcements via a live region, keyboard-driven accordion and language switcher, prefers-reduced-motion handling. Deployed on LiteSpeed with custom deploy/rollback skills and a 24-project portfolio rendered server-side from JSON for SEO.

I designed and developed greeksimmers.com, a full-stack web application for a flight simulator business in Greece. The platform features a robust booking system with Stripe payments, a tier-based loyalty program, a magazine/blog system, and a comprehensive admin panel. Key features include dynamic working hours and closure periods, email templates for bookings and rescheduling, multilingual support (Greek/English), and GSAP scroll animations with glassmorphism effects. I implemented high security patches, responsive design across all pages, and optimized images with automatic WebP conversion. The project involved extensive client communication and iterative development across 4 phases.

Magic Admin replaces the traditional CMS with a conversation. Each client gets a split screen — an assistant on the left, a live preview of their own site on the right — and asks for changes in plain language, in English or Greek. The assistant reads and edits the real files, shows every tool call as it runs, and stages the result as a draft.

It runs as a single multi-tenant instance alongside the agency's existing client sites, with per-tenant credit accounting, a media library, webhooks, and an agency-side billing view over the top.

What Do You Do is a browser RPG in which the game master is a language model. It narrates the world and voices its characters, while a deterministic TypeScript rule engine owns everything mechanical — dice, damage, travel, quests — so the story can be improvised without the rules ever becoming negotiable.

Characters are built in five steps and finish by answering an in-character questionnaire, which the model turns into a backstory, traits, fears and motivations. The narrator's language is chosen in that first step and locked for the life of the character, because the synthesized backstory, the memories and the entire exchange history are written in it.

Paper86 is a multi-tenant platform for restaurants and cafés: menus, floor plans, staff and roles, waiter ordering, a kitchen display, and QR self-ordering for guests. One owner runs several stores under a single organization, each on its own subscription.

It is multilingual in a way that matters operationally. The interface ships in English, Greek and German, but a store's menu content is not limited to those — an owner picks whichever languages they actually serve in, and every content form grows a field per language. A guest scanning the QR code at their table reads the menu in the language they choose, prices and modifier groups intact.
