App Backend & APIsServices
Design and build secure, observable, and scalable backends and APIs—ready for production traffic and growth.
Our App Backend & APIs Services
From API design and auth to data, caching, queues, observability, security, and automated delivery.
API Design (REST/GraphQL)
Resource modeling, versioning, pagination, filtering, error contracts, and schema governance.
Learn moreAuthentication & Authorization
OAuth2/OIDC, JWTs, session management, passwordless, RBAC/ABAC, and multi‑tenant isolation.
Learn moreData & Storage
PostgreSQL/MySQL modeling, NoSQL (Mongo/Redis), search (Elasticsearch), migrations, and performance tuning.
Learn moreCaching & Performance
Redis caching, HTTP caching, CDN, N+1 elimination, connection pooling, and performance budgets.
Learn moreMessaging & Queues
Event‑driven architectures with RabbitMQ/Kafka/SQS, outbox pattern, retries, and idempotency.
Learn moreObservability & Ops
Structured logging, metrics, traces, alerting (OpenTelemetry/Prometheus/Grafana) and SLO/error budgets.
Learn moreSecurity & Compliance
Threat modeling, rate limiting, IP allow/deny lists, secrets management, audits, and GDPR/PCI readiness.
Learn moreCI/CD & Delivery
Automated tests, blue/green or canary deploys, infrastructure as code, and rollback strategies.
Learn moreOur App Backend & APIs Process
A clear, quality‑gated process that takes you from architecture to reliable operations.
Discovery & Architecture
Domain modeling, API contracts, data stores, async patterns, and non‑functional requirements.
Implement & Integrate
Service scaffolding, endpoints/resolvers, authZ, validations, and integrations with third‑party services.
Test & Harden
Contract tests, load tests, chaos testing, security scans, and observability dashboards.
Launch & Operate
Deploy, monitor SLOs, incident response runbooks, and continuous improvements.

Frequently Asked Questions
Answers about timelines, stack choices, auth/security, deployment, and migrations.
Small services 2–4 weeks; larger platforms are phased. We provide a detailed plan at kickoff.
Depends on your team and needs—Node/NestJS, FastAPI/Django, or Go are our primary choices.
Yes—OAuth2/OIDC, RBAC, rate limits, audits, and compliance‑ready designs are standard.
We set up CI/CD, IaC, monitoring, and runbooks for smooth operations post‑launch.
We can incrementally modernize services with strangler patterns and data migration plans.
