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.

Authentication & Authorization

OAuth2/OIDC, JWTs, session management, passwordless, RBAC/ABAC, and multi‑tenant isolation.

Learn more

Data & Storage

PostgreSQL/MySQL modeling, NoSQL (Mongo/Redis), search (Elasticsearch), migrations, and performance tuning.

Learn more

Caching & Performance

Redis caching, HTTP caching, CDN, N+1 elimination, connection pooling, and performance budgets.

Learn more

Messaging & Queues

Event‑driven architectures with RabbitMQ/Kafka/SQS, outbox pattern, retries, and idempotency.

Learn more

Observability & Ops

Structured logging, metrics, traces, alerting (OpenTelemetry/Prometheus/Grafana) and SLO/error budgets.

Learn more

Security & Compliance

Threat modeling, rate limiting, IP allow/deny lists, secrets management, audits, and GDPR/PCI readiness.

Learn more

CI/CD & Delivery

Automated tests, blue/green or canary deploys, infrastructure as code, and rollback strategies.

Our 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.

Why Choose Us

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.
