P4 · Enterprise Software Development
Product engineering, not body shopping.
We build custom software the way we build our own products: small senior teams, modern stacks, automated testing, and an architecture that survives contact with production — from web and mobile front ends to APIs and BI dashboards.
ScopeWhat we do
- Custom software & SaaS — enterprise systems and multi-tenant products on Java, Spring Boot, React, TypeScript, and cloud-native microservices.
- API platforms — REST APIs with real contracts, versioning, and documentation; integrations that survive the third party's next breaking change.
- Mobile apps — iOS and Android, native or React Native, sharing your platform's APIs, identity, and security model — with passkey-grade sign-in built by identity specialists.
- BI & reporting — self-serve dashboards and governed reporting on Metabase and Superset, access-controlled through your IAM.
- Modernization — J2EE-era and homegrown systems migrated incrementally to stacks people still want to work on, with tests as the safety net.
The standard we bring: our own codebase ships with a certified OpenID Connect implementation, architecture rules enforced in CI, and blocking quality gates. That bar doesn't lower for client work.
