Art Director Building brands that connect, compete, and grow
Cover image for PAC — Brand Identity PAC brings
PAC — Brand Identity PAC brings together over 30 years of combined experience in project management, property administration, construction, and maintenance services. The challenge was translating that depth of expertise into a visual identity that could compete on a different level —one that felt clear, modern, and professional in a sector where most players look the same. The project was built from scratch: every visual asset and communication strategy developed with a single goal in mind —differentiation. The result is a brand that reflects the seriousness and scale of what PAC actually delivers, and has since become a recognizable presence in their market.

Cover image for Anarí — Brand Refresh Anarí already
Anarí — Brand Refresh Anarí already existed. It worked. But there was a gap between what the brand actually was and what it was showing the world. Behind Anarí is an independent fashion designer with a distinct voice, a genuine obsession with Vivienne Westwood, and an aesthetic that lives in the tension between punk rock and high fashion. The work was closing that gap —reinterpreting the brand's ideology and building a visual system that could finally match its real personality. The process started with concept. Graphic elements from the designer's own creative process were recovered and reintegrated, the color palette was simplified, and an expanded visual language was layered in: punk rock, high fashion photography, torn paper as a graphic device, and the energy of strong, fresh-spirited brands like Stüssy. All of it held together by a system that doesn't constrain —it amplifies. The deliverables covered the full refresh: new brand guidelines, website design, and art direction for the brand's audiovisual presence across social media and graphic content. Every piece built to say the same thing —an independent fashion brand that doesn't ask for permission.

Cover image for Obec Foods — Full Branding Obec
Obec Foods — Full Branding Obec Foods had a starting point —but it needed a fresh start. The brand produces oat-based cookies, granola, and muffins made from homemade recipes. The core idea is straightforward and honest: healthy snacks that complement an active lifestyle without asking you to give up what you love. That proposition became the center of gravity for the entire rebrand. The project covered full brand development: concept, brand guidelines, handmade illustrations, packaging, and key visuals for graphic content. The illustrations were one of the most defining elements of the project —drawn by hand to reinforce the artisanal nature of the products and give the brand a warm, distinctive personality. The color palette follows the same logic: vibrant, natural, and health-forward, without falling into the visual clichés of the wellness world. The result is an identity that holds together across every touchpoint —from packaging to communication pieces— and speaks directly to people who live actively and choose what they consume with intention. Obec Foods isn't a diet brand. It's a brand for conscious enjoyment.

Cover image for Adamus Accessories — Full Branding Some
Adamus Accessories — Full Branding Some brands arrive with a story worth telling from scratch. Adamus Accessories came with a singular material —bonded marble— and a clear conceptual obsession: alchemy. The challenge was building a visual universe from the ground up that could carry the weight of that inspiration. With no existing identity to work from, the process started where it had to: concept. Three pillars defined the visual direction —gothic art, sacred geometry, and alchemy as the brand's philosophical and aesthetic keystone. Every design decision that followed had to earn its place within that symbolic system. The logo was one of the most rewarding problems to solve. The brief was to compress three ideas into a single mark: the A as origin, the elemental star, and the phoenix as a symbol of transformation. The result fuses all three into a precise geometric form with a subtle resonance to masonic symbolism —enigmatic without being cryptic, distinctive without being loud. The scope covered the full brand ecosystem: brand identity, brand guidelines, art direction for graphic and audiovisual content, social media, stationery, packaging, and e-commerce website design. Every touchpoint was treated as part of a unified experience, not a collection of isolated deliverables. Art direction was the second major challenge —and the second major achievement. Translating the physical nature of the pieces into a visual language for screen and print required finding the exact tension between fashion, statement, and darkness. The outcome is an aesthetic that doesn't imitate its references —it distills them. Visuals that communicate the brand's personality before a single word is read. Adamus isn't an accessories brand that uses alchemy as decoration. It's a brand built inside out, where the symbol and the object are the same thing.

Cover image for Redesigning my web portfolio (https://estiguar.vercel.app)
Redesigning my web portfolio (https://estiguar.vercel.app) to optimize user retention. 👨‍💻 I just wrapped up a complete restructuring of my personal web portfolio using React, Tailwind, and Vite. The goal wasn’t just a visual facelift, but solving real-world optimization and UX challenges that often get overlooked. Here is a breakdown of what I prioritized during this sprint: * Mobile performance & interactivity: I optimized the tsParticles integration by capping the frame rate at 120 FPS for high-refresh-rate displays and eliminated abrupt edge-bounce calculations. The result? Lower battery consumption and smoother, more natural transitions. * Immersive UI/UX: I implemented a subtle, dynamic spotlight effect that follows the cursor, layered over an ultra-faint technical grid on a dark background. The focus was finding the perfect balance between modern aesthetics and readability. * Modular architecture: I refactored the projects section using asymmetrical layouts and optimized modals. These components break down the engineering behind each build—ranging from AI integrations with Llama 3 to IoT telemetry via MQTT. Check out the video to see the full walkthrough and how the micro-interactions respond in real time. If you are looking for a developer who combines clean code with a strict focus on product performance, let’s connect. I am available for new high-impact freelance projects.

Cover image for Rediseñando mi portafolio web para
Rediseñando mi portafolio web para optimizar la retención de usuarios. 👨‍💻 Acabo de terminar la reestructuración completa de mi portafolio web (https://estiguar.vercel.app) personal utilizando React, Tailwind y Vite. El objetivo no era solo actualizar el diseño visual, sino resolver problemas reales de optimización y experiencia de usuario que suelen pasarse por alto. Aquí un resumen de lo que prioricé en este sprint: * Rendimiento e interactividad móvil: Optimicé la integración de tsParticles limitando los FPS a 120 para pantallas de alta tasa de refresco y eliminé cálculos bruscos de rebote en los bordes. Menos consumo de batería, transiciones más naturales. * UI/UX inmersiva: Implementé un efecto dinámico de spotlight sutil que sigue al cursor y una cuadrícula técnica ultra-tenue sobre un fondo oscuro, buscando un balance entre estética moderna y legibilidad. * Arquitectura modular: Refactoricé la sección de proyectos con layouts asimétricos y modales optimizados que explican detalladamente la arquitectura de cada desarrollo (como integraciones de IA con Llama 3 o telemetría IoT mediante MQTT). En el video puedes ver el recorrido completo y cómo responden las micro-interacciones en tiempo real. Si estás buscando un desarrollador que combine código limpio con un enfoque estricto en el rendimiento de producto, hablemos. Estoy disponible para nuevos proyectos de alto impacto.

Cover image for I recently made several improvements
I recently made several improvements to the design of my developer portfolio (https://estiguar-vercel-app.translate.goog/?_x_tr_sl=es&_x_tr_tl=en&_x_tr_hl=es&_x_tr_pto=nui). The main goal was to simplify navigation, improve user experience, and reduce loading times. By optimizing resources and responsive design, I managed to make the site look and function more smoothly on all types of devices. In addition, I adjusted the content and structure to focus on what really matters: highlighting my skills in Full-Stack, AI, and automation. I also did a complete review of SEO tags, such as meta descriptions, titles, and the use of relevant keywords to improve organic positioning. The result is a clearer, faster, and more optimized portfolio that better reflects what I do and how I can help solve real problems.

Cover image for Many auto repair shops still
Many auto repair shops still manage repairs via WhatsApp, physical notes, and constant calls asking, “Is it ready yet?” I decided to build Fixly (https://fixly.pythonanywhere.com), a SaaS platform for organizing repairs, estimates with photos, and automatic notifications from a single dashboard. The idea was not just to digitize, but to design a simple system that truly reduces operational friction. I developed it as an indie dev: rapid validation, multi-tenant SaaS architecture from the start, and a freemium model to facilitate adoption.
