Custom software built for how San Jose companies actually run
Kadmoon serves San Jose companies the way a serious buyer expects: full-time engineers, a working demo every two weeks, and a system that ships with the repo, credentials, and runbook in your hands. You are never locked into us.
In a tech-heavy market like San Jose, the bar for product quality is high. We build SaaS platforms, internal tools, and data products that hold up under real load.
What we build for San Jose teams
From the core system to the model in production.
SaaS Platforms
Multi-tenant products with recurring billing, white-label onboarding, analytics dashboards, and documented public APIs—architected to scale from 10 to 10,000 customers without a rewrite.
Mobile Apps
Native and cross-platform (React Native) apps for iOS and Android—product-grade UX, offline-first when needed, and direct integration with your backend.
Integrations & APIs
We connect your ecosystem: legacy ERPs, US Customs/ACE, payment gateways, marketplaces, and any third-party REST/SOAP API. Resilient middleware with retry, dead-letter, and full observability.
Data & AI
Ingestion pipelines, data warehouses, BI dashboards, ML models for forecasting and classification, and LLMs via RAG for semantic search, report generation, and intelligent automation—built into the system, not bolted on.
Legacy Modernization
Migration of COBOL, Delphi, VB6, and legacy .NET/PHP to a modern stack. Monolith-to-microservices refactoring, cloud migration, and elimination of critical technical debt.
Flagship practice
Trade & supply chain software, wherever you ship.
Customs and trade operations, US Customs/ACE integration, shipment tracking, landed cost, and end-to-end supply chain visibility in one system. It is our deepest domain, and it travels well to any San Jose operation that moves goods.

Do you build custom software for companies in San Jose?
Yes. Kadmoon works with clients across the United States, including San Jose, California, from our engineering base in Austin, TX. We handle discovery, architecture, build, QA, and go-live, all with a senior in-house team on US business hours.

Enterprise systems like ERPs and CRMs, multi-tenant SaaS products, mobile apps, integrations and APIs, data and AI features, and legacy modernization. Trade and supply chain is our flagship practice. Every system is custom and owned by you.
Do we own the code you build?
Completely. On delivery you receive the Git repository, CI/CD pipelines, infrastructure credentials, and an operational runbook. No lock-in and no permanent dependency on us, in San Jose or anywhere else.
How fast can a San Jose project start?
Tell us about the project and you get a technical proposal within one business day, covering scope, architecture, timeline, and investment. Discovery usually starts within a week or two of a signed scope.
