Sivan Software Inc. · Los Angeles, California
Software built and run by the person who wrote it.
A one-person shop. No handoffs, no layers between the architecture and the keyboard. Right now the whole of it is going into bridgetable.club — an online bridge platform for people who play at a club.
Currently building
bridgetable.club
Duplicate and social bridge on the web, iOS, and Android. Four players at a table with video, a bidding engine that explains its reasoning, and double-dummy analysis on every hand after you play it.
Built for club players — the people who show up on a Tuesday afternoon and want a table that behaves like the one they left.

The stack
One monorepo, three workspaces.
This is the working manifest, not a logo wall. If you want to know what this shop actually reaches for, it is on this page.

How the work gets done
Boring convictions, held firmly.
Modular by default
Clear seams between packages, so a change stays where you put it.
Tests that mean something
Unit and integration coverage on the logic that would actually cost you a bug.
Continuous delivery
Every commit builds, tests, and reports. Releases are unremarkable events.
Open source, proven patterns
Nothing invented that a well-maintained library already does better.
Prior work
Before this.
Network management application
Several hundred screens for network configuration, monitoring, and management, deployed across multiple client intranets.
Switch and router architecture
Software architecture for high-performance layer-4 switching hardware.
One of the best software architects I have worked with. His diligence and creativity led Zuma to the most advanced layer 4 switch router on the market.
