Consumer apps, marketplaces and AI-powered tools — design & build.
Peter Neyra · see hardware →

Four products. Several visual systems. One person.

These span two countries, several product categories, and completely different audiences — from Bulgarian food-drop enthusiasts to Spanish house flippers — plus the internal tools I built to run them.


Each has its own design language built from scratch: warm paper and hand-drawn pixel art for a farm-direct food drop; translucent dark glass and WhatsApp-native flows for a renovation marketplace; precision typography and AI-curated data for a house-flipping tool; lifestyle matching and isochrone maps for a property concierge.


Designed and coded end-to-end — no agency, no handoff, no framework I didn't choose deliberately.

01 · Vitrina · 2026

Vitrina
farm drops

Problem. Small farms grow exceptional food but can't reach city shoppers, who pay main-street markups for less. Distribution is the bottleneck.
Solution. Vitrina pools a neighbourhood's demand — people pre-order personalised groceries from small local farms with their neighbours; when an area hits critical mass the drop goes ahead at near-wholesale, collected from a local shop's rented fridge. A phone-first waitlist ranks demand area-by-area before a euro is spent.
Stack. Pure HTML/CSS/JS landing · Supabase · FastAPI on Hetzner · Vercel · bilingual BG/EN. Open it for the live site, the gamified waitlist, and the founder tracker.

Leo
housing concierge

An AI housing co-pilot for Spain. You don't pick filters — you tell Leo how you live, and it finds the rentals and homes worth your time, with a tailored checklist for every serious viewing. Four personas (renters, buyers, buyer agents, relocation) in one bilingual landing, an isochrone "sweet-spot" map, listing-vs-reality mockups, and a voice-first intake. The most design-dense build of the set.

05 · Smart Supply Router · 2026

Routing
simulator

Problem. A warehouseless food supplier routes fresh produce straight from farms to restaurants — no depot to buffer demand, so every order is a direct multi-stop run and the margin lives or dies on routing.
Solution. A browser simulator of real farm→restaurant mornings: pick the orders, it pulls real road distances (OSRM), solves the vehicle-routing problem with a self-hosted VROOM engine, and breaks down the true per-drop cost — goods, last-mile, overtime, distance — to show whether the unit economics work before a van leaves.
Stack. Vanilla JS · Leaflet · OSRM road network · self-hosted VROOM solver · scenario data (farms / restaurants / depot).
