Rapida · Delivery Service Platform
A high-performance delivery platform with real-time tracking and immersive 3D visualizations.
Enterprise work in Los Angeles is rarely a blank page. We do four things. We modernize core systems that cannot be switched off, using strangler-fig sequencing where new services take routes one at a time behind an API gateway while the legacy core keeps serving the rest, so no single release can take down a hospital registration desk or a utility billing run. We build the integration and platform layer that institutions never funded: an event backbone, an API gateway with real rate limiting and audit, a single identity plane, and infrastructure as code so environments stop being hand-built artefacts. We build new systems where none exists, which in this market means content rights and participations tracking, permitting and inspection workflows, research administration, clinical operations tooling and utility field service. And we do platform engineering and cost work: Kubernetes standardisation, CI/CD that a regulated organisation can actually approve, observability that shows a request end to end, and cloud spend reduction on estates that were lifted and shifted without redesign. Every engagement includes an accessibility track from the start, because public sector and university buyers in California cannot accept a system that fails WCAG, and retrofitting accessibility after a build costs several times what designing it in costs.
We start with an architecture assessment that produces a dependency map, not a slide deck: what calls the core, what batch jobs run in which window, which interfaces have no owner, and where the data actually lives. For institutional buyers we then agree a sequencing plan that names, for each capability, whether it moves first, moves late or never moves, because the honest answer for some mainframe subsystems is that they stay and get an API in front of them. Discovery includes a regulatory pass keyed to the buyer: HIPAA and California's Confidentiality of Medical Information Act for health systems, FERPA for universities and school districts, CJIS for anything touching law enforcement data, PCI DSS for payment paths, and the CPPA risk assessment obligation that started January 1 2026. Build is paced by the parallel run rather than by the sprint board: a carved-out capability is not done when it passes tests, it is done when it has produced the same answer as the legacy core on production traffic for an agreed period, with the differences investigated rather than waved through. Chandigarh runs overnight regression, load tests and release rehearsals so a Los Angeles morning starts with results. Releases go out behind feature flags with a documented rollback that has been executed in a rehearsal, not just written down. For public sector buyers we plan around procurement and board calendars from day one, because those dates move for nobody.
We assess the current landscape — systems, integrations, data ownership, security posture and the constraints nobody wrote down — then define target architecture and a delivery sequence tied to business outcomes.
Domain modelling, API contracts, identity and permission design, data classification and non-functional requirements agreed with your security and infrastructure stakeholders before code is written.
Cross-functional squads deliver in two-week sprints with CI/CD, automated testing and environment parity. Every sprint produces something demonstrable in an environment your stakeholders can log into.
End-to-end integration testing, penetration testing, load and failover testing, accessibility review and structured UAT with business process owners.
Phased rollout by business unit or region with a rehearsed runbook, then managed support against agreed SLAs, on-call rotation and a funded enhancement backlog.
We work in the stacks these estates already run. Java with Spring Boot and .NET 8 and 9 dominate the institutional core; Node with TypeScript and Go serve new service work; Python carries data and machine learning. Front ends are React and Next.js, with strict WCAG 2.2 AA conformance and keyboard-first design. Data sits on PostgreSQL, Oracle Database and SQL Server, with Kafka or Amazon Kinesis as the event backbone and Debezium for change data capture off systems we are not allowed to modify. Legacy sources include COBOL on z/OS, IBM i and RPG, Oracle Forms and PowerBuilder, which we wrap rather than rewrite where the business case does not support a rewrite. Kubernetes runs on EKS, GKE or AKS, provisioned by Terraform, with Argo CD for delivery. Identity runs on Okta, Microsoft Entra ID or Ping, with SCIM provisioning and SAML or OIDC federation into campus and county directories. Observability is OpenTelemetry into Datadog or Grafana. Hosting decisions at this tier are usually settled by procurement language rather than by benchmarks: public agency and university solicitations in California frequently specify where data may be stored, which government cloud boundary applies, and whether a FedRAMP or StateRAMP authorisation is required, and those clauses eliminate most of the option set before latency is ever discussed. We read those terms first, then design to the regions and service tiers that survive them, and we keep the deployment portable enough with Terraform and Kubernetes that a boundary change is a redeploy rather than a re-architecture.
