API Engineering
APIs are the contracts that hold modern systems together. I design and build APIs that are secure, well-documented, and built to handle real production traffic—from initial architecture through deployment and monitoring.
A good API is invisible to the end user and a pleasure for developers to consume. Whether it's a REST service backing a mobile app, a GraphQL layer aggregating microservices, or an OAuth proxy bridging your application to a financial platform, every endpoint I build follows the same principles: clear contracts, predictable behavior, and graceful failure.
I bring hands-on experience integrating with major financial platforms, payment processors, and identity providers. Security isn't an afterthought—it's embedded in every authentication flow, every input validation check, and every error response.
Capabilities
RESTful API Design
Resource modeling, versioning strategies, pagination, filtering, and hypermedia controls following industry best practices and OpenAPI standards.
GraphQL Development
Schema design, resolver architecture, DataLoader patterns, subscriptions, and federation for flexible, efficient data fetching.
Authentication & Authorization
OAuth 2.0 flows, JWT management, API key strategies, role-based access control, and secure token lifecycle handling.
Third-Party Integration
Financial APIs, payment processors, identity providers, and SaaS platform connectors with resilient error handling and retry logic.
Rate Limiting & Throttling
Token bucket and sliding window algorithms, per-client quotas, and graceful degradation to protect your services under load.
Real-Time Communication
WebSocket server design, Server-Sent Events, pub/sub patterns, and event-driven architectures for live data delivery.
Technologies
Use Cases
Financial Services Integration
Secure API proxies and token management for brokerage platforms, banking APIs, and market data feeds with strict compliance requirements.
Microservice Communication
Service-to-service API contracts, schema validation, circuit breakers, and distributed tracing for reliable inter-service communication.
Public Developer APIs
Developer portal design, API key provisioning, usage metering, rate limiting, and comprehensive documentation for external consumers.
