High-Throughput API & Microservices Engineering for Australian Systems
Connect disparate platforms, automate data pipelines, and power modern client applications with high-throughput backend APIs. Mr Umer Malik designs secure, fully documented RESTful and GraphQL APIs in Go, Node.js, and PHP for Australian fintechs, logistics operators, and retail platforms in Sydney and Melbourne.
Core Capabilities & Production Deliverables
Direct architectural execution by senior engineer Mr Umer Malik with zero agency dilution.
Sub-40ms Low-Latency Architecture
Compiled Go and Node.js microservices engineered for high throughput, processing thousands of requests per second with minimal compute footprint.
GraphQL Schemas & Federation
Flexible GraphQL APIs allowing mobile and web frontends to query exactly the data required in a single request, eliminating over-fetching.
OAuth2, JWT & Mutual TLS Security
Enterprise API authentication featuring short-lived JWT tokens, rate limiting per IP/API key, and mTLS for banking integrations.
Interactive OpenAPI & Swagger Docs
Self-documenting API endpoints with interactive Swagger test sandboxes, typed request/response schemas, and SDK generation.
Event-Driven Webhooks & Kafka Queues
Resilient asynchronous message brokering utilizing Redis and RabbitMQ to guarantee reliable webhook delivery without dropped payloads.
AWS Sydney VPC & Private Gateway
APIs deployed inside isolated AWS Sydney VPC subnets with CloudWatch telemetry and automatic horizontal auto-scaling.
Why Australian Enterprises Rely on Custom APIs
Generic third-party middleware introduces latency, security risks, and recurring subscription costs. Here is why purpose-built APIs deliver higher ROI.
Ultra-Low Latency for Australian Users
Hosting in AWS Sydney (ap-southeast-2) delivers sub-30ms round-trip API responses to users in Sydney, Melbourne, Brisbane, and Adelaide.
Seamless Australian Ecosystem Connectivity
Direct automated bridges connecting Xero, Australia Post, Stripe AU, BPay/PayID, and enterprise ERPs like SAP and NetSuite.
Strict Compliance with APRA & Privacy Standards
Built-in request logging, audit trails, and encryption at rest and in transit satisfying Australian regulatory standards.
Zero Recurring Middleware Subscriptions
Eliminate expensive monthly fees for intermediary integration platforms like Zapier or MuleSoft by deploying owned microservices.
Phased Delivery Roadmap & How This Project Runs
Structured from initial discovery call to production deployment and 100% intellectual property transfer.
Phase 01: API Contract & Data Schema Design
Specifying RESTful endpoints or GraphQL schema, payload validation rules, and authentication mechanisms using OpenAPI standards.
Phase 02: Core Microservices & Database Engineering
Writing performant handler logic, optimized database queries, connection pooling, and automated unit tests with high coverage.
Phase 03: Security Hardening & Rate Limiting
Configuring OAuth2 token exchange, IP rate limiting, WAF filtering, and simulated load testing to verify concurrency thresholds.
Phase 04: Production Deployment & Telemetry Setup
Deploying to AWS Sydney ECS/Lambda, configuring CloudWatch alarms, and delivering developer documentation and sandbox keys.
