Software Development
API Design & System Integrations
We connect your applications, data sources, and third-party platforms into seamless, reliable workflows — eliminating manual data transfers, reducing errors, and giving every system in your stack a single source of truth.
What We Build
API & Integration Capabilities
From designing clean API contracts to building middleware that connects legacy systems — we make your entire technology stack work as one.
REST & GraphQL API Development
Well-designed, versioned, documented APIs following OpenAPI / Swagger standards. Built with authentication (OAuth 2.0, JWT, API keys), rate limiting, caching, and comprehensive error handling from day one.
Third-Party API Integrations
Integration with payment gateways (Stripe, PayPal, Adyen), CRMs (Salesforce, HubSpot), ERPs (SAP, Odoo), marketing platforms, social media APIs, and hundreds of SaaS tools — maintaining reliable, monitored connections.
Middleware & iPaaS Development
Custom middleware layers, event-driven architectures, and integration platform setup (Zapier, MuleSoft, n8n, or bespoke Node.js middleware) that route, transform, and validate data between systems.
Data Pipeline & ETL Integration
Extract, transform, and load pipelines that synchronise data between your CRM, ERP, data warehouse, and analytics platforms — with full data validation, deduplication, and error handling.
Webhook & Event-Driven Automation
Real-time event processing via webhooks and message queues (RabbitMQ, Kafka, AWS SQS) — enabling your systems to react instantly to events without polling or manual triggers.
Legacy System Connectivity
Wrapping legacy applications, SOAP services, FTP feeds, and database-level integrations in modern APIs — giving old systems a new, maintainable interface without requiring a full replacement.
How We Work
Our Integration Delivery Process
A methodical approach that maps your systems, designs clean interfaces, and delivers integrations that stay reliable long-term.
Integration Discovery
We map every system, data flow, and manual process in your stack — identifying integration points, data ownership, frequency requirements, and error handling needs.
API & Data Contract Design
We design the API contracts, data schemas, and transformation rules before writing code — reviewed and approved by all stakeholders to prevent downstream rework.
Development & Testing
Integration code is built with full test coverage — unit tests for transformations, contract tests for API compatibility, and end-to-end tests against sandbox environments.
Staging Validation
The full integration stack runs in a staging environment mirroring production — with synthetic data flows validated against every edge case and failure mode.
Monitored Go-Live
Production deployment with real-time monitoring, alerting on failures, automatic retry logic, and a dead-letter queue for any messages that fail to process.
Ongoing Maintenance
API versioning management, third-party API change monitoring, and proactive alerting ensure your integrations stay reliable as platforms evolve.
Why SharpLogic
Why teams trust us with their integrations
Reliability engineering
Retry logic, circuit breakers, idempotency, and dead-letter queues — built into every integration so transient failures never become data loss.
Observable integrations
Every integration ships with logging, tracing, and alerting. You can see exactly what data moved, when, and why anything failed — no black boxes.
Documentation that lasts
Every API and integration is documented in OpenAPI format with usage examples, error codes, and change logs — making future maintenance fast and low-risk.
Full-stack integration team
Backend engineers, data engineers, and DevOps working together — so integrations are built, deployed, and monitored as a complete, production-ready system.
