WEB APPS

Calpak USA develops full-stack web applications purpose-built for hardware-centric organizations including IoT device management platforms, manufacturing execution system (MES) dashboards, production analytics portals, fleet monitoring interfaces, calibration tracking systems, and secure customer portals for accessing test data and compliance documentation. Our Hawthorne, California engineering team builds these applications using modern frameworks like React, Next.js, SvelteKit, and Node.js with TypeScript for type-safe, maintainable codebases. Calpak USA web applications integrate directly with your embedded devices through MQTT brokers and WebSocket connections, and with enterprise systems through REST and GraphQL APIs. Every web project is developed under our AS9100 and ISO 9001 quality system with documented requirements, architecture reviews, automated testing, and release management processes tailored to the compliance needs of aerospace, defense, and medical device clients.

Calpak USA builds real-time web dashboards that ingest and visualize live telemetry from hundreds of connected devices simultaneously using MQTT message brokers, WebSocket connections, and server-sent events for efficient push-based data delivery. Our engineers implement time-series databases like InfluxDB and TimescaleDB to store high-frequency sensor data alongside PostgreSQL for relational operational data. Calpak USA dashboards feature configurable chart widgets, real-time gauges, geospatial device maps, threshold-based alerting with email and SMS notifications, and historical trend analysis with adjustable time windows. We optimize front-end rendering performance using virtualized lists, canvas-based charting libraries like D3.js, and efficient state management to maintain smooth performance even with rapid data update rates. Every dashboard Calpak USA delivers includes role-based views so operators, engineers, and management each see the metrics relevant to their responsibilities.

Calpak USA deploys web applications on AWS, Microsoft Azure, and Google Cloud Platform, selecting the optimal cloud provider based on your existing infrastructure, compliance requirements, and geographic latency constraints. Our engineers architect deployments using containerized services with Docker and Kubernetes for horizontal scalability, managed databases including RDS, Cloud SQL, and Cosmos DB, and serverless compute using AWS Lambda and Azure Functions for event-driven workloads. Calpak USA implements infrastructure-as-code using Terraform and CI/CD pipelines through GitHub Actions and GitLab CI for automated testing, staging, and production deployments. We configure auto-scaling policies, load balancing, CDN distribution, and multi-region failover for applications that require high availability. All cloud architectures designed at our Hawthorne, California facility include cost optimization reviews, monitoring dashboards using CloudWatch or Datadog, and documented disaster recovery procedures.

Calpak USA implements defense-in-depth security architectures for every web application, including OAuth 2.0 and OpenID Connect authentication, role-based and attribute-based access control, TLS 1.3 encryption for data in transit, and AES-256 encryption for data at rest. Our engineers integrate with enterprise identity providers through SAML and LDAP for single sign-on, and implement multi-factor authentication for privileged access. Calpak USA conducts OWASP Top 10 vulnerability assessments, implements content security policies, rate limiting, input sanitization, and parameterized database queries to prevent injection attacks. For applications handling controlled unclassified information or ITAR-regulated data, Calpak USA configures compliant hosting environments with audit logging, session management, and data residency controls. All web applications developed at our Hawthorne, California facility undergo security review as part of our AS9100 and ISO 9001 certified development process before production deployment.

Calpak USA designs and builds production-grade REST and GraphQL APIs that serve as the integration backbone between your web applications, embedded devices, mobile apps, and enterprise systems. Our engineers develop RESTful APIs following OpenAPI 3.0 specification with versioned endpoints, pagination, filtering, and comprehensive Swagger documentation. For applications requiring flexible data queries across complex device hierarchies, Calpak USA implements GraphQL APIs with schema stitching, subscription support for real-time updates, and DataLoader patterns for efficient database access. We build webhook delivery systems for event-driven integrations with ERP, MES, and quality management platforms. Calpak USA APIs include JWT-based authentication, rate limiting, request validation, and structured error handling. All API projects delivered from our Hawthorne, California facility include automated integration test suites, Postman collections, and developer onboarding documentation so your internal teams can consume the APIs independently.

Calpak USA builds all web applications with responsive design as a core architectural requirement, using CSS Grid, Flexbox, and container queries to deliver fully functional interfaces across desktop workstations, tablets on the factory floor, and mobile phones in the field. Our engineers implement progressive web app capabilities including service workers for offline access, app manifest files for home screen installation, and background sync for intermittent connectivity scenarios common in industrial environments. Calpak USA designs touch-optimized control interfaces for tablet-based operator stations and data-dense analytical layouts for desktop engineering workstations, adapting information density and interaction patterns to each form factor. We test across Chrome, Safari, Firefox, and Edge on Windows, macOS, iOS, and Android using automated cross-browser testing with Playwright. All responsive implementations follow WCAG 2.1 accessibility standards to ensure your application is usable by all team members regardless of ability.
