Resilient API Engineering & Microservices for Canadian Enterprises
Build the rock-solid backbone for your digital products. Mr Umer Malik designs and deploys high-throughput RESTful and GraphQL APIs for Canadian corporations, fintech scale-ups, and logistics providers in Toronto, Montreal, and Calgary. Engineered in Go and Node.js for sub-40ms database responses, automated documentation, comprehensive rate limiting, and airtight PIPEDA compliance.
Core Capabilities & Production Deliverables
Direct architectural execution by senior engineer Mr Umer Malik with zero agency dilution.
RESTful & GraphQL API Architectures
Clean, intuitive API endpoints designed for high performance, typed contracts, and seamless consumption by web and mobile frontends.
Sub-40ms Database Response Times
Optimized SQL query execution, connection pooling, and in-memory Redis caching delivering instantaneous response times under heavy concurrent load.
Enterprise Authentication & Rate Limiting
OAuth2, JWT tokens, API key rotation, IP rate limiting, and DDoS mitigation protecting your core backend infrastructure.
Automated OpenAPI & Swagger Documentation
Interactive, auto-generated API specifications that allow your internal teams and external partners to integrate effortlessly.
Microservices & Event-Driven Message Queues
Decoupled service architectures utilizing RabbitMQ or AWS SQS to handle asynchronous processing, webhooks, and background jobs reliably.
Sovereign Canadian Cloud Deployment
Containerized Docker microservices deployed across multiple availability zones in AWS Canada Central (ca-central-1) with auto-scaling.
Why Canadian Enterprises Invest in Custom APIs
Fragile third-party connectors and sluggish backend code choke enterprise growth. Robust APIs ensure reliable data flow and high scalability.
Engineered for Heavy Concurrency
Compiled backends built to process thousands of requests per second with zero connection leaks, memory spikes, or thread locking.
PIPEDA & Financial Compliance
Encrypted database fields, secure audit logs, and zero-trust authentication complying with Canadian data governance requirements.
Fixed CAD Pricing & 100% IP Transfer
Stage-by-stage proposals in Canadian Dollars under Canadian NDA, with complete unencumbered repository ownership upon delivery.
Direct Senior Backend Partnership
Collaborate directly with principal engineer Mr Umer Malik. No junior developers learning on your critical production infrastructure.
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 Model Design
Defining OpenAPI schemas, payload contracts, authentication protocols, and database models under mutual NDA.
Phase 02: Core Microservice & Database Development
Developing compiled Go or Node.js endpoints, configuring PostgreSQL indices, and implementing Redis cache layers.
Phase 03: Automated Test Suites & Load Stressing
Writing unit, integration, and load tests to verify sub-40ms performance under simulated peak Canadian traffic.
Phase 04: Production Deployment & Monitoring Setup
Deploying to AWS Canada Central with Docker, setting up Prometheus and Grafana telemetry, and completing documentation handover.
