Cover image for Innovative App Template for Selling Physical Products Creati...

I built a way to sell physical products in an app that feels more like a gallery than a shop. 📱 What does it do? It’s a remix-able template for selling physical products inside an app. You browse through pieces in a horizontal carousel, then scroll vertically through a product to explore it through multiple images before buying instantly with Apple Pay. I designed it for galleries and artists first, but it works for anyone selling physical products creators, brands, influencers anything that needs to feel a bit more premium. Why I built this: I kept thinking about how intentional artwork is presented in physical spaces, and how transactional it feels online. This is an attempt to close that gap and making purchases feel as frictionless as possible. Another bonus to why people will use this app is that apple does not tax physical good transactions, so sellers can keep more of what they earn. 🎉 The template remix-potential? Works really well because users can swap in any product and it simply works! Art, jewellery, vinyls, collectibles, anything physical allowed on the app store. This was fun I plan on refining and making more templates so I would appreciate any comments and feedback Build Preview 👀 (https://www.anything.com/mobile-preview/68217499-f987-4843-8bcb-f7864c536abc)Build Link 🔗 (https://www.anything.com/build/aCF0mfmHSEOLy_eGTFNqvA?v=sBZM6bBFQ0CWHu4QlFbZpA)

Cover image for To mark 122 years of

To mark 122 years of Ford Motors, this Super Bowl advertisement speaks directly to multi-generational audiences who value heritage, perseverance, and the powerful connection between sound and emotion. The story of the horse and carriage draws a parallel between the original Mustang and its modern counterparts, building towards anticipation before the unveiling of the new 2026 Mustang in Spring. The Location: Santa Clara, California played a huge role in the story as this year's Super Bowl is being hosted at the at Levi's Stadium. This made prompting the clothing easier, you'll notice each actor is wearing Denim.

I think I pushed my limits on this one.. 🛏️ My goal was to use all the tools in unison and learn how each tool could own a clear layer of the full product experience from code to marketing. Rork developed the app, Suno designed the audio, FLORA defined the visual language, Tolstoy for all the UGC, and Replit brought it online. After Christmas dinner, I sent my first prompt to Rork: “Design a digital members club for Gen-Z + working professionals committed to sleeping earlier in 2026.” The idea came from an old note I wrote after a health & wellness conference in Budapest: 'productivity revolves around a good night’s sleep' - marketing = Maslow's Hierarchy of Sleep (iOS app) ' 😬😂 And so? Pillow FM: A modern sleep experience for overstimulated minds. 'Guided Sleep meditations everyday at 10pm' Shall I continue this app?

Built a poker training app where you can practice real poker spots — Cash or Tournaments, any stack depth, any number of players. After every decision, it sends the hand to AI and gives you feedback on the spot. Still a work in progress: I’m refining some game logic and planning to add solver-based trees so you can drill only the tricky situations and cut down on unnecessary AI calls. Curious what you all think! Link: https://884bda6655f34706867ee4687c8d3512-main.projects.builder.my

Cover image for Reflections Boutique Hotel - Website

Reflections Boutique Hotel - Website URL (https://reflectionsonrarotonga.com/) Introduction Reflections on Rarotonga is a sister property to Rumours Luxury Villas in Muri Lagoon. This intimate, wellness-focused retreat offers the same exceptional luxury and privacy that defines the Rumours experience. The Challenge The resort needed a digital presence that matched their luxury positioning and the quality of their sister property. An outdated website that didn't capture the luxury experience, slow mobile load times affecting guest experience, and a need for consistency with Rumours brand standards. The Solution I built a modern website that matches the quality and aesthetic of their sister property Rumours: a custom Node.js build with fast load times, a mobile-first design capturing the luxury resort aesthetic, SEO targeting high-intent travel keywords, and branding consistent with Rumours Luxury Villas. The Result The new website delivers a cohesive luxury experience that aligns perfectly with the Rumours brand while highlighting Reflections' unique wellness-focused offerings.

Citro - SaaS - Website URL (https://www.joincitro.com.au/) Introduction Citro provided their new website design and hired me to develop the full build in Webflow. My role was to translate the approved designs into a clean, performant, and scalable Webflow implementation. The Challenge Bring a design system into Webflow with high fidelity while maintaining clarity, responsiveness, and a premium feel. The site also needed to communicate product value without overwhelming users, and support future content updates. The Solution I developed the site in Webflow using the Client-First methodology, built reusable components for long-term maintainability, and implemented custom animations to introduce polish and visual clarity aligned with the design. The build was optimised for responsiveness and content readability.

Dogbase - SaaS Company - Website URL (https://www.dogbase.co/) Introduction DogBase purchased a Webflow template and hired me to transform it into a fully functional website that matched their branding and product messaging. I was responsible for the full setup, customisation, and launch inside Webflow. The Challenge Templates often provide a visual starting point, but rarely match the brand structure, content needs, or UX of a real company. The challenge was to adapt the template to DogBase's identity, organise content, and ensure the final site felt cohesive and professional — not like a generic template. The Solution I configured and customised the template in Webflow, updated typographic and colour systems to match DogBase's brand, reorganised sections for better clarity, and integrated their content and product copy. I also ensured responsive behaviour, SEO basics, and a clean CMS structure for future updates. The Result The final site delivered a complete, branded, and polished Webflow experience without the cost of a ground-up redesign. DogBase received a fully functional website aligned with their brand and ready for real-world use, demonstrating how a template can become a professional product when implemented correctly.

Cover image for Rumours Hotel Website - Website

Rumours Hotel Website - Website URL (https://rumours-rarotonga.com/)Introduction Rumours Luxury Villas is a luxury retreat in Muri Lagoon, designed for those seeking absolute privacy, romance, and a world-class experience. In an adults-only setting, their villas offer private pools, tropical gardens, and direct beach access. The Challenge The resort was losing potential guests due to an outdated online experience that didn't match their luxury positioning. A 6-second mobile load time was driving away 53% of mobile visitors. 80% of bookings were coming through OTAs with 15-20% commission fees. Their WordPress site was difficult to update and maintain. The Solution I rebuilt their entire digital presence from the ground up, focusing on speed, direct bookings, and operational efficiency: a custom Next.js website with sub-2-second load times, a mobile-first design capturing the luxury resort aesthetic, SEO targeting high-intent travel keywords, and automated email sequences for pre-arrival and post-stay. The Result The new website delivers a premium experience that matches the resort's luxury positioning, with dramatically improved performance and a streamlined booking process designed to increase direct reservations.

AI Agent Security Auditor | Fast, evidence-based reviews

Cover image for I recently completed a security

I recently completed a security hardening pass on an AI-enabled mobile product. The most important issues weren’t exotic vulnerabilities. They were practical deployment risks: password reset race conditions missing abuse controls weak retention guarantees mobile backup exposure logging and CI gaps Each confirmed finding was fixed and backed by regression tests before the security baseline was marked PASS. One lesson stood out: security reviews are most useful when they produce evidence and actionable fixes, not just scanner output. I’m now offering focused 24-hour AI Agent Security Mini-Audits for founders and small teams. https://contra.com/s/2Z7YgYXU-ai-agent-security-mini-audit?r=guillaume_strohecker_6m06cchc

Cover image for Mobile Security & Privacy Hardening
Security

Mobile Security & Privacy Hardening Security hardening focused on mobile platform protections and privacy-preserving behavior. Android application backup was disabled to reduce risk around locally stored session material, and release builds were hardened to block cleartext traffic while keeping local development support isolated to debug/profile builds. The review also verified that BLE remains anonymous, one-sided interest stays private, precise coordinates are not exposed publicly, and Social Heat remains aggregate and threshold-gated.

Cover image for API Rate Limiting & Abuse

API Rate Limiting & Abuse Protection Security hardening focused on API abuse resistance. Rate limits were added to registration, login, password-reset request and confirmation, Click Intent creation, and public Heat reads. The limiter was designed with bounded state, explicit email normalization, case-sensitive reset-token fingerprints, expiry sweeping, and fail-closed behavior under saturation. Regression tests verified throttling behavior and recovery.

Cover image for Authentication & Password Reset Hardening
Security

Authentication & Password Reset Hardening Security hardening focused on authentication and account recovery. The work included stronger scrypt password hashing, legacy-hash migration, login timing protections, atomic password-reset token consumption, and session revocation after reset. PostgreSQL concurrency and regression tests verified that a reset token can only be successfully consumed once and that authentication behavior remains safe under failure conditions.
