Software, infrastructure, and digital products.
I build software, infrastructure, and digital products that turn real problems into clear, dependable systems.

Technologies I work with
Your library. Every format. One calm, beautiful home.
A multi-source media reader and player for manga, anime, novels, movies, and series, with a modular TypeScript plugin system.
Plugin system
One content model
Manga, anime, novels, movies, and series share the same library, progress, and workflows.
Independent sources
Every source is an independent TypeScript module and uses an injected SourceContext instead of global fetch.
Remote installation
Plugin repositories can live on any static host and are managed from the Plugins screen.
AgroLens
In developmentFrom field to dataset, even offline.
An offline-first platform for capturing, organizing, and annotating agricultural images for computer vision datasets.
Data flow
- Field capture
- Local queue
- Sync
- Review
- Annotation
- Export
Offline first
Collection does not depend on an active connection: images and metadata are stored locally and synced when the network returns.
Metadata as part of the data
Every batch carries its agronomic context from capture time, reducing unlabeled images.
Clients separated from processing
Slow operations, such as upload completion and inference, run in workers outside the HTTP API.
Security and operations
Refresh token rotation, pre-signed uploads, rate limiting, audit trail, health checks, and documented backups.
