Sivan Software

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.

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.

Corporate engagement

Network management application

Several hundred screens for network configuration, monitoring, and management, deployed across multiple client intranets.

Earlier

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.
