Building Marka, an open-source, self-hostable personal library for everything people want to save and revisit, from movie watchlists and shopping wishlists to social posts, articles, design references, and course files. Marka brings these scattered saves into one searchable, cross-device archive and preserves their context with visual previews, tags, and reader views.

Built an AI personal-finance assistant with a team of five. It reads supported bank emails into a ledger you review before anything counts, then tracks budgets, goals, and a month-end spending forecast.

Built an Indonesian equity intelligence platform that filters multi-source market updates with AI and delivers source-linked news and analyst trade plans to Discord. Under the hood, Hermes cron jobs use Hermes Agent to process and deliver market updates, backed by Python pipelines for ingestion, deduplication, retries, and delivery receipts, Supabase configuration, and Next.js web apps for operators and readers.

An agent-first Git worktree manager with isolated slots, port offsets, automatic setup and teardown, concurrency locking, safety checks, and shell navigation for running multiple coding agents on one project without collisions.
