AI-powered app-store management platform — a team of autonomous agents that handle review replies (40+ languages), ASO, multi-territory pricing, and app submissions across the App Store and Google Play, usable from Slack/Teams/Discord or an API instead of a dashboard. I work full-stack on the product (Laravel + Inertia + Filament backend, React/TypeScript frontend, AI/LLM integrations) as an AI Developer at Cleevio Labs.

An AI generator for iOS app icons and App Store screenshots — generate custom icons and localized, on-brand screenshots, backed by a curated gallery for inspiration. I built it nearly end-to-end: Django + DRF backend with async generation (Django-Q2), React 19 / Vite / TypeScript frontend, fal.ai image generation, OpenRouter prompt translation, and WorkOS auth, deployed via Docker + Caddy + GitHub Actions. Built as a lead-generation product for Uprate.

Live

Freemium PWA that turns a social-video link (TikTok, Instagram Reels, YouTube) into a structured recipe — ingredients, steps, macros, and cost estimates. A Next.js 16 / React 19 web app on Supabase (Postgres + RLS + Auth) with Stripe billing, backed by a Python 3.14 / FastAPI extraction service (yt-dlp + OpenAI Whisper) that uses Claude via OpenRouter for structured extraction and the USDA FoodData Central API for nutrition. Self-hosted on Hetzner via Docker Compose + Caddy, with a companion React Native / Expo mobile app. Solo full-stack build.

Live

A Discord AI companion with persistent memory, written in Go. Runs one goroutine per active channel; on each message it recalls relevant memories via hybrid semantic search over SQLite vector embeddings, builds a prompt from a per-server \"soul\" file plus recalled memories, and runs a tool-calling loop through an LLM (OpenRouter) — saving/recalling memories, reacting, and searching the web. Memories survive restarts and are scoped per server; DMs get isolated memory automatically.

A novelty offline iOS app (React Native / Expo) whose compass arrow points toward the nearest — or a randomly chosen — pub. All pub data is bundled on-device (sourced from the Overpass / OpenStreetMap API), so it works with no internet connection after install. Free, ad-free, MIT-licensed.

Contract engagement: I rebuilt the eremvole.cz e-commerce and brand site from scratch, migrating it off a legacy Nette 2.4 / PHP 7.4 codebase onto Django 5.2 + Next.js 16. I did the full rewrite and built the new feature set, including migration of legacy production data and media into the new system. The store itself belongs to the client; the rewrite and ongoing development are my work. Containerised with Docker Compose behind Caddy.

Live at eremvole.cz; full rewrite delivered as a freelance engagement.
