Backend, APIs & Integrations

The engine behind your application. RESTful APIs, microservices, database optimization, and third-party integrations.

MySQL, PostgreSQL, Elastic Search for complex queries. We handle legacy modernization, system integrations, and standalone modules for larger products. If you have a specific technical challenge, we're happy to dig in.

Backend systems that work

We build server-side systems that power applications. APIs, microservices, databases, integrations - engineered for reliability and performance.

What we build

RESTful APIs that frontend and mobile teams love to work with. Proper authentication, rate limiting, error handling, documentation.

GraphQL services when clients need flexibility. Schema design, resolvers, performance optimization.

Microservices when monoliths need to be broken up. Service boundaries, inter-service communication, managing the complexity.

Third-party integrations. Payment processors, CRMs, ERPs, shipping providers - we connect your system to external services.

Background processing. Job queues, scheduled tasks, event-driven processing. Systems that handle work reliably without blocking user requests.

How we work

We design APIs before implementing them. Clear contracts, consistent patterns, documentation from the start.

Authentication, authorization, input validation, rate limiting built in from day one. Not bolted on later.

Database query optimization, caching strategies, connection pooling. We measure and optimize before problems occur.

Logging, metrics, and tracing that help you understand what's happening in production. Debugging shouldn't require guesswork.

Technologies

Languages: Node.js (Express, Fastify, NestJS), Python (FastAPI, Django), PHP (Laravel), Go for performance-critical services.

Databases: PostgreSQL, MySQL for relational. MongoDB, DynamoDB for documents. Redis for caching and queues. Elasticsearch for search.

Message queues: RabbitMQ, AWS SQS, Redis Streams, Kafka.

API tools: OpenAPI/Swagger documentation, GraphQL with Apollo, gRPC for internal services.

Common integrations

Payment processing: Stripe, PayPal, Adyen, local payment methods.
Authentication: OAuth providers, SSO, identity management.
Communication: Email (SendGrid, SES), SMS (Twilio), push notifications.
Storage: S3, Cloudflare R2, CDN integration.
Analytics: Segment, Mixpanel, custom event tracking.

Deliverables

Well-documented APIs with OpenAPI specs. Integration tests and test environments. Deployment configurations and CI/CD. Monitoring and alerting. Performance benchmarks. Security review documentation.

What We Offer

REST API Development

Clean, well-documented REST APIs following best practices. Versioning, pagination, error handling done right.

GraphQL Implementation

Flexible APIs that let clients request exactly what they need. Subscriptions for real-time updates.

Microservices Architecture

Breaking monoliths into manageable services. Event-driven communication, service discovery, distributed tracing.

Third-Party Integrations

Payment gateways, CRMs, ERPs, shipping providers. We connect your systems to the services you need.

Frequently Asked Questions

What backend technologies do you work with?
We specialize in Node.js, TypeScript, Python, and Go. For frameworks, we use Express, Fastify, NestJS, and Django. We design RESTful APIs, GraphQL services, and event-driven architectures depending on your requirements.
How do you ensure backend scalability?
We design for scalability from the start using microservices architecture, horizontal scaling patterns, caching strategies, and message queues. We also implement load testing and monitoring to identify bottlenecks before they affect users.
Can you improve our existing API performance?
Yes, we conduct API performance audits covering database query optimization, caching, connection pooling, and architectural improvements. We have experience improving response times and reducing infrastructure costs for existing systems.
Do you build REST APIs or GraphQL APIs?
Both. REST is our default for most projects because it's simpler and well-understood. GraphQL makes sense when clients need flexibility in data fetching or when you have many different consumers. We'll recommend the right approach based on your specific situation.
How do you ensure API security and authentication?
We implement industry-standard authentication with OAuth 2.0, JWT tokens, and API keys where appropriate. Every API includes rate limiting, input validation, and proper error handling. Our security background means we think about attack vectors from the start.
Can you integrate with payment gateways and third-party services?
Yes. We've integrated Stripe, PayPal, Adyen, and various regional payment providers. Beyond payments, we connect to shipping APIs, CRMs like Salesforce and HubSpot, accounting systems, and custom enterprise software. We handle the complexity so your team doesn't have to.
