Product Designer & Dev — Figma to shipped SaaS & apps.
Cover image for BlockFlow — AI-powered software for
BlockFlow — AI-powered software for UK block managers. BlockFlow is management software I designed and built end-to-end for UK residential block managers. Beyond the core admin (service charges, arrears, contractor invoices), it adds automation the incumbents don't have: it chases contractors for quotes and escalates by SMS after 48h, and an AI voice agent answers out-of-hours emergency calls — deciding whether it's a real emergency, raising the ticket and alerting the on-call contractor automatically. Built solo: Next.js, Supabase (multi-tenant with row-level security), Claude for triage, and a Vapi voice agent. Live in production.

Cover image for AI Automation Agency — Landing
AI Automation Agency — Landing Page Design (StackD) UI/UX Design, Landing Page, Figma Designed a conversion-focused landing page for StackD, an AI automation agency serving property managers and building administrators. The brief: translate a technical service (AI-driven workflow automation — supplier emails, issue follow-ups, booking management, insurance claims, resident communications) into a page that speaks to time saved and control gained, not features. What I designed: A clear, editorial hero with a serif/sans pairing for contrast — "Your management, automated" — paired with a quantified value prop (40h saved/month, 0 forgotten emails) instead of generic claims A "before/after" section mapping manual tasks directly to their automated equivalent, so the visitor immediately sees their own workflow reflected A soft, high-contrast palette (black, white, lime accent) to keep the page feeling premium and calm rather than "salesy" A modular services grid ("What we build for you") designed for easy expansion as the agency's service list grows Tools: Figma (full UI design, component structure, layout system) My role: sole designer — wireframes, visual design, component system, and final high-fidelity mockup.

Cover image for StackD — the website for
StackD — the website for my own dev & automation agency StackD builds the software businesses actually need: custom websites, native apps, SaaS platforms, and turning manual processes into automated flows. I designed and built its website end-to-end. The goal Position StackD as the lean, transparent alternative to traditional agencies — "real products in the hands of real users, not mockups." Fast demos, a fixed 3-person team, no hidden costs. The site had to feel modern, technical and trustworthy in seconds. What I built A fast, responsive marketing site with clear sections: Services, Process (4 steps), Projects, Team and FAQ Terminal-style touches ($ whoami) to give it a developer personality A portfolio section featuring real shipped products (SMASH, NOOK, Volea.io (http://Volea.io), Getflow) Copy and structure optimized to convert visitors into "no-commitment" discovery calls How I built it Next.js + HTML/CSS for a fast, SEO-friendly front end Deployed on Vercel (CI/CD, edge, instant previews) Built AI-assisted with Claude Code — pairing with an AI coding agent to design, iterate and ship faster than a solo dev normally could The takeaway This is how StackD works, proven on itself: idea → live product in days, not months. The agency site isn't a brochure — it's a demo of the exact speed and quality we deliver to clients.

Cover image for 🎾 I built and shipped
🎾 I built and shipped a padel app. Solo. From idea to the App Store. This is SMASH — and here's the whole story, the stack, and who it's for. The problem I lived I play padel. And like everyone who plays, I was organizing matches across four different WhatsApp groups, arguing about who won, with no real ranking and no easy way to run a club league. Clubs were managing tournaments in Excel. The fastest-growing sport in the world had no home on your phone. So I built one. What SMASH is An iOS app that turns padel into a social, competitive experience: • Organize matches and track results • A real ELO ranking, by city and by level — win, you climb; lose, you drop • Leagues & tournaments where the app auto-generates the bracket and standings • Matchmaking ("I want to play") that fills your game with players nearby • A short-video feed for your best padel moments • Push notifications that bring you back ("you've been challenged", "you moved up to #3 in your city") How I built it (the stack) Frontend: • Flutter / Dart — one codebase, iOS-first • Riverpod for state management • Custom UI (Material + Cupertino, glass effects), fully localized (ES/EN) • Video pipeline: playback, caching, compression, thumbnails Backend — 100% serverless on Firebase: • Cloud Firestore — real-time database for users, matches, squads, leagues, tournaments • Cloud Functions (2nd gen, Node 24) — server-side ELO calculation, a push-notification fan-out system, and city-based matchmaking • Firebase Auth (Google + Apple Sign In) • Firebase Cloud Messaging for push (APNs) • Firebase Storage for media • Security rules + composite indexes Monetization: • RevenueCat + StoreKit 2 — subscriptions, freemium model (play for free, organize as Pro) Systems I built from scratch: • The ELO algorithm (K=32, team-average) for fair competitive ranking • A round-robin generator for tournaments • A viral invite loop (a padel match needs 4 players → every game created is an invitation) Who it's for Primary — padel players, from casual to competitive: people who play weekly and want to organize better, measure their real level, and compete. Starting in Spain, expanding to the padel hotspots: Italy, Sweden, Germany, the US (Miami, California), and Australia. Secondary (B2B) — padel clubs: run official leagues and tournaments with zero paperwork, and add a booking link so players find and book courts. Recurring, defensible revenue. What I actually learned Shipping alone means being the product manager, designer, Flutter dev, backend engineer, growth marketer and App Store submitter — often in the same afternoon. I learned that features don't make a startup; loops do — a retention loop (notifications), a growth loop (invites), and a business model that scales. I learned that "global from day one" is a trap: 500 real users in one city beats 0 scattered worldwide. And I learned that the last 10% — App Store review, push certificates, subscription approvals — is where most side projects quietly die. So I pushed through it. SMASH is live on the App Store now, and I'm building it in the open with the players who use it. If you play padel, run a club, or just like watching a product get built from zero — I'd love your feedback.

Since COVID (2020), many businesses have had their revenues affected, but possibly one of the most affected has been the restoration. Nacho (founder) realized that since COVID, tips in restaurants had fallen a lot, so he wanted to propose a solution. ‍ In our case, we developed a product that would make the experience very simple. Using a QR code (which, if its use has been extended during the pandemic), the customer selects the waiter who has served him, gives him a score and indicates that he wants to give him a tip. Using the Stripe® payment gateway, we make the payment. Both the restaurant and the employee (waiter) can control their tips digitally and all this without having to integrate a new ERP.

Shimoku provides real-time Auto-Machine Learning (artificial intelligence) solutions in a few clicks so that digital marketing specialists can answer business questions. Its multiapplication platform, based on real-time artificial intelligence predictions, currently has two products. The product itself is complex to explain, so we had to create a product aimed at “simplifying” the experience and making it graphically understood.
