Enterprise API &
Microservices Engineering
We design, build, and secure high-throughput RESTful, GraphQL, and gRPC API ecosystems, connecting enterprise applications, cloud microservices, third-party SaaS, and real-time WebSockets.
API SLA & Performance Metrics
Purpose-Built Integration Solutions
Tailored API engineering for microservices, payment processing, SaaS integrations, and event streams.
Enterprise Microservice Backbones
Decouple legacy monoliths into high-speed gRPC & REST microservices with automated service discovery.
FinTech & Payment Gateway APIs
Secure Stripe, M-Pesa, Plaid, & banking API integrations with tokenized credentials and PCI compliance.
Third-Party Enterprise SaaS Connectors
Seamless bi-directional synchronization with Salesforce, HubSpot, SAP, NetSuite, & custom ERPs.
Real-Time WebSockets & Event Streams
Event-driven Kafka & WebSocket architectures for instant chat, live tracking, and telemetry dashboards.
Public Developer API Portals
Monetizable developer portals, SDK generators, API key management, rate-limiting, and interactive docs.
Legacy Middleware Modernization
Refactor fragile SOAP / XML legacy services into lightweight, high-performance JSON REST and GraphQL APIs.
API Engineering Practice
From RESTful OpenAPI specs to GraphQL federation, gRPC microservices, and OAuth 2.0 security.
RESTful & OpenAPI Contract Specs
We design clean, versioned RESTful APIs (v1/v2) adhering strictly to OpenAPI 3.0 specifications. Complete with interactive Swagger documentation, standardized JSON response schemas, and error handling.
API SLA Delivery Standards
- Sub-10ms response latency & Redis caching
- OAuth 2.0, OIDC, JWT, & HMAC signature security
- Kong / AWS API Gateway rate-limiting & DDoS shielding
- 100% intellectual property & OpenAPI spec ownership
How We Engineer APIs
A contract-first, test-driven engineering lifecycle from OpenAPI design to production gateway deployment.
API Domain Modeling & Contract Specs
We model resource entities and write clear OpenAPI 3.0 / Protobuf contract specs before writing business logic.
Security & OAuth2 Auth Design
Define access control roles (RBAC), OAuth 2.0 scopes, rate-limiting rules, and token validation specs.
Microservice & Database Endpoint Coding
Agile 2-week sprint development building high-concurrency Node.js, Go, or Python FastAPI endpoints with Redis caching.
k6 Load Testing & Benchmarking
Rigorous automated load testing using k6 and Postman to verify sub-10ms response latency under heavy concurrency.
API Gateway & CI/CD Deployment
Deploy containerized APIs to Kubernetes or AWS with Kong Gateway routing and automated deployment pipelines.
Developer Portal & Telemetry SLA
Publish interactive Swagger documentation, configure Sentry error tracking, and provide 24/7 APM monitoring.

API Engineering FAQ
Answers to common questions regarding REST vs GraphQL vs gRPC, rate-limiting, and webhook delivery retries.
REST is ideal for public developer APIs and standard CRUD web services due to universal client compatibility. GraphQL is superior for complex web/mobile apps where clients require flexible queries without over-fetching. gRPC (Protocol Buffers) is recommended for internal microservice-to-microservice communication where sub-5ms low latency and high binary throughput are critical.
