A closer look at selected projects, their constraints, implementation details, tests, and visual checks.
Open source tool
Dadbod Grip stages table edits, exposes generated SQL for review, and sends the batch as one transaction script. A CLI error can leave an earlier statement committed, so the database must be inspected before retry. DuckDB can join PostgreSQL, MySQL, SQLite, MotherDuck, and local or HTTPS files in one query.
Shipped at scale
I led Unity and C# multiplayer with Photon and PlayFab. Four players can grip into a live chain while one flies a jetpack, so its bodies, joints, and collisions remain part of the shared simulation. The game passed 50 million downloads; launch week peaked above 32,000 concurrent Twitch viewers.
Live prayer book
Pray Orthodox brings Church offices, appointed propers, Scripture, saints, fasting guidance, and Bible reading into one quiet surface. A source-pinned appointment engine composes each date from fixed services and variable liturgical corpora. Every rendered prayer retains its source and locator. If a required form or proper is incomplete, it stays out of the public schedule instead of being replaced by a generic prayer.
Python bakes the calendar and Bible data into files for each day, month, chapter, and search route. Expo builds the shared interface for web and native. The web reader loads those files without waiting for a runtime API or database startup.
Founding engineering
Nucleus shows leaders adoption, estimated opportunities and savings, workflow gaps, and where to consider further investment. I replaced the Bubble prototype with the production React and TypeScript platform, translated Figma designs into reusable components, and built the product experience that presented the data science team's assessment outputs. My scope later expanded into backend, data, infrastructure, authentication, and release work.
Deep dive
Case: dadbod-grip.nvim
Dadbod Grip adds editable grids, generated SQL previews, cross-database queries, schema navigation, profiling, notebooks, and schema-aware AI to the editor.
Dadbod manages connections. DuckDB joins databases and files. Dadbod Grip adds workflows without hiding the SQL or replacing either system.
- ALTER TABLE users ADD last_seen_at TIMESTAMP;
+ ALTER TABLE users ADD last_seen_at TIMESTAMPTZ;
+ CREATE INDEX idx_users_last_seen_at
+ ON users (last_seen_at DESC);The test matrix covers editing state, generated SQL, adapters, the interface, and regression paths on Neovim stable and 0.10 with DuckDB installed.
The Softrear demo database puts a 17-table schema tree, query editor, staged grid markers, and the generated Live SQL in one Neovim view. Review checks that the selected table, pending edits, and exact statement remain legible together before apply.
