Vibeans Solutions Custom API Engineering & System Integrations

Architecting High-Throughput APIs & Integrations for Modern Enterprises

We engineer fault tolerant REST, GraphQL, and gRPC application programming interfaces. From Stripe billing and banking gateways to multi-vendor ERP bridges, we guarantee sub 50 millisecond response times and ironclad security.

Engineering Capabilities

What We Build & Deliver

Production-hardened architectures engineered from day one for extreme scale, security, and velocity.

01

Custom RESTful & GraphQL API Architecture

Cleanly structured, versioned, and documented API endpoints engineered with strict schema validation and high-speed in-memory caching.

  • Strict OpenAPI 3.1 specifications with automated Swagger documentation
  • GraphQL Federation for distributed multi-team enterprise schemas
  • Sub-50ms query responses leveraging Redis distributed caching
02

Payment Gateway & Financial Systems Integration

Flawless integration of international and domestic payment rails, automated recurring billing engines, and ledger reconciliation.

  • PCI-DSS compliant Stripe Connect, PayPal, and PayFast implementations
  • Automated dispute handling, dunning cycles, and invoice generation
  • Multi-currency settlement and automated taxation via Stripe Tax
03

High-Volume Webhook Event Buses

Scalable ingestion engines designed to process tens of thousands of incoming webhook events per second without dropping connections.

  • Cryptographic HMAC signature verification on all incoming payloads
  • Decoupled asynchronous worker queues ensuring instantaneous 200 OK responses
  • Automated replay mechanisms for failed partner deliveries
04

Legacy ERP & Enterprise Database Modernization

Lightweight wrapper microservices that expose legacy SQL databases and internal systems as secure, modern RESTful APIs.

  • Zero downtime migration patterns with dual-write replication
  • Granular OAuth 2.1 and JWT token-based role authentication
  • Complete rate limiting and API abuse prevention via Cloudflare

How We Work

Our 4-Phase Delivery Framework

01

Interface Contract & Data Schema Modeling

We define rigorous OpenAPI contracts, payload structures, and error states before writing code.

02

High-Performance Implementation

Engineers build asynchronous microservices optimized for connection reuse and low-latency database pooling.

03

Automated Fuzzing & Security Auditing

Every endpoint undergoes automated OWASP Top 10 security fuzzing, rate-limit penetration testing, and load spikes.

04

Gateway Deployment & Traffic Telemetry

We deploy behind modern API gateways with real-time latency monitoring, alerting, and automated failover.
