Projects and case studies
A selection of what I've shipped, the what and the how.
Claudio for Android
A personal productivity app for Android, built around my Notion workspace. Notion is the source of truth; Claudio is the mobile interface that makes it usable day-to-day — with Claude AI on top for daily briefs, task summaries, and a conversational assistant.
Solaar
A multi-agent development agency built entirely with Claude Code. One orchestrator, eight specialized agents, and a persistent intelligence layer — the system knows your stack history, your production state, and which structural patterns in generated code are likely to fail before they reach users.
Vitals
Vitals by mariansan — a personal health intelligence platform for Galaxy Watch and Fitbit. Wearable data flows in automatically from two sources; Claude Sonnet synthesizes it into a daily briefing, trend analysis, and an AI coach.
Balboa Finance
Personal financial assistant. Ingests credit card statements from Gmail, captures physical receipts via Claude Vision, categorizes across 11 fixed spending buckets, and surfaces pending transactions for one-tap confirmation before anything gets persisted.
Claudio Chief of Staff Bot
An AI-powered Telegram bot designed to act as a personal Chief of Staff. Claudio helps manage priorities, draft communications, track tasks, and keep things moving — available wherever you are.
Control Tower
A personal Claude Code usage dashboard built into mariansan.io. Tracks token consumption across all projects — input, output, cache reads/writes, estimated cost, sessions, and turns. Supabase-backed ingest API, HMAC-SHA256 cookie auth, Recharts daily breakdown with range picker, and two sync scripts: one for org accounts via the Anthropic Admin API, one reading local SQLite directly.
Trend Intelligence
Full-stack AI trend intelligence platform for Central America and the Caribbean. Two verticals — food & beverage and pet nutrition — from a single codebase. Type a category and get a complete strategic brief in under 3 minutes, grounded in live signals from Google Trends, YouTube, Reddit, and Firecrawl.
Custom MCPs Development
Integrated my applications with custom Model Context Protocol servers to extend my AI ecosystem. Built to ensure the right tools available when I need them — connecting my existing stack directly to my AI workflows.
Lumen News Bot
An AI-powered Telegram bot that curates and delivers personalized news briefings. Lumen aggregates content from multiple sources and surfaces what matters most to each user — making it easy to stay informed without the noise.
VeggieCorner
A recipe journal focused on plant-based cooking, integrated with Claude AI for recipe and image creation. VeggieCorner helps me keep track of favorite recipes and lets users explore vegetarian and vegan dishes with a clean, modern interface built for everyday use.
