High-Throughput REST & GraphQL API Engineering for Pakistani Digital Platforms
Power your mobile apps, partner integrations, and internal systems with ultra-fast, secure APIs. Mr Umer Malik engineers production-grade RESTful and GraphQL APIs in Go, Node.js, and modern PHP—designed for high-concurrency scaling, rate-limited security, and full OpenAPI documentation for Pakistani tech companies.
Core Capabilities & Production Deliverables
Direct architectural execution by senior engineer Mr Umer Malik with zero agency dilution.
High-Concurrency Golang & Node.js Endpoints
Lightweight compiled endpoints processing thousands of concurrent requests per second with sub-50ms execution times.
Type-Safe GraphQL Schemas
Flexible, self-documenting GraphQL schemas preventing over-fetching and giving frontend teams exact query control.
OAuth2, JWT & API Key Governance
Role-based authentication, granular token scope validation, and automated API key rotation protecting confidential endpoints.
Redis Caching & Tiered Rate Limiting
Token bucket and leaky bucket rate limiting preventing DDoS attacks and brute-force abuse while ensuring high availability.
Interactive OpenAPI / Swagger Documentation
Comprehensive, live interactive documentation allowing internal developers and third-party partners to integrate seamlessly.
Automated Unit & Integration Test Suites
Automated CI/CD test coverage verifying schema validation, response codes, and database transactions on every commit.
