What we deliver
Twara Technologies designs, builds and operates the server-side systems that mobile apps depend on. A mobile app is usually only as reliable as its backend: the APIs that serve data, the services that authenticate users, send notifications, process payments and store files, and the integrations that connect the app to the rest of your business.
Mobile backends face particular constraints. Networks are slow or intermittent, devices retry requests, and several app versions are in use at once because not everyone updates. We design for those realities from the start.
Typical scope
- API design: resources, operations, error formats, pagination and versioning, captured in a machine-readable specification.
- Authentication: email or phone sign-in with one-time passwords, social sign-in, Sign in with Apple, enterprise single sign-on and token lifecycle management.
- Authorisation: roles, ownership rules and object-level checks.
- Data storage, search and caching.
- Push notifications, in-app messaging and email or SMS delivery.
- File and media upload, processing and secure delivery.
- Payments and subscriptions, including server-side validation of in-app purchases.
- Integrations with ERP, CRM, payment and logistics systems.
- Admin tools, analytics events and reporting.
- Hosting, scaling, monitoring and backups.
Technologies we work with
| Area | Options | When we tend to choose each |
|---|---|---|
| Languages and frameworks | Node.js with NestJS or Express, Python with Django or FastAPI, Java or Kotlin with Spring Boot, Go, .NET | Matched to your team, existing systems and performance profile. |
| API style | REST with OpenAPI, GraphQL, gRPC for internal services | REST for broad compatibility; GraphQL for flexible client queries; gRPC between internal services. |
| Backend-as-a-service | Firebase, Supabase, AWS Amplify | Rapid starts, smaller teams, real-time features out of the box. |
| Databases | PostgreSQL, MySQL, MongoDB, Redis, DynamoDB, Firestore | Relational for transactional integrity; document and key-value stores for flexible or high-volume access patterns. |
| Messaging | Apple Push Notification service, Firebase Cloud Messaging, queues such as Amazon SQS, RabbitMQ or Kafka | Push for user notifications; queues for reliable background processing. |
| Hosting | AWS, Microsoft Azure, Google Cloud; containers or serverless functions | Containers for steady workloads; serverless for spiky or event-driven ones. See cloud services. |
How we approach it
- Design the contract. Agree the API with the app team before implementation, so mobile and backend work can proceed in parallel against mocks.
- Model the domain and data. Entities, ownership rules, retention and the queries that screens need most.
- Set the foundations. Environments, infrastructure as code, CI/CD, secrets management and monitoring from the first sprint.
- Build in increments. Endpoints delivered with automated tests and documentation as they are built.
- Test for real conditions. Load tests at expected peaks, retry and timeout behaviour, and security testing.
- Launch and operate. Gradual rollout, alerting tuned to meaningful signals, and an on-call or support arrangement agreed with you.
Quality, security and performance
- API security. We test against the OWASP API Security Top 10 (2023). Its list includes broken object level authorisation, broken authentication, unrestricted resource consumption and server-side request forgery, each of which maps to specific design decisions and tests in our work.
- Client and server together. The OWASP MASVS covers network communication and authentication on the app side; we design the backend so that those controls are supported, for example short-lived tokens, refresh token rotation and TLS everywhere.
- Store-related server duties. Apple’s App Store Review Guidelines require in-app account deletion where an app supports account creation, and ask for a working back-end service and demo account during review. We build deletion workflows that actually remove or anonymise data across services, and keep review environments ready.
- Personal data. Under the Digital Personal Data Protection Act, 2023, individuals have rights to correction and erasure of personal data they consented to share, and data fiduciaries must take reasonable security safeguards. We design data models, retention jobs and deletion flows to support these obligations, with legal interpretation from your advisers. These provisions are being brought into force in phases; our DPDP guide tracks the dates.
- Performance and resilience. Caching, connection pooling, idempotent writes, graceful degradation and autoscaling based on measured load.
- Observability. Structured logs, metrics and traces with dashboards and alerts agreed with you.
Engagement options
- API and backend build. A defined backend delivered alongside a new app, by us or by your app team.
- Backend modernisation. Replacing or re-platforming an existing backend behind live apps, without breaking released versions.
- Managed operations and support. Monitoring, patching, scaling and enhancements via our support and maintenance service.
Tell us about your app and the systems behind it, and we will propose a backend architecture.
