Google Cloud Serverless Developer | Pulumi IaC | Node.js APIs & Automation
I want to appreciate the outstanding work delivered on the project. The implementation of the serverless pipeline on GCP using Pulumi IaC and Node.js APIs was highly professional. The automation and infrastructure setup reflect strong expertise as a Cloud Engineer, and the solution is robust, efficient, and production-ready.

AWS Lambda Architect, Scalable API & Event Solutions, Serverless Backend with nodeJs
Great work on building the scalable event-driven notification system! I appreciate how you used AWS Lambda, Node.js, API Gateway, and SQS effectively to handle asynchronous notifications. The Dead Letter Queue implementation, email notifications, and template management show strong attention to reliability and real-world usability. The system is well-architected for scalability, fault tolerance, and low operational cost, and your serverless approach reflects solid expertise. Excellent job overall!

Job Success
Karachi, Pakistan - 3:50 pm local time
I build backend systems, cloud infrastructure, and mobile & web applications that are production-ready, scalable, and cost-efficient.
7+ years. Real results:
⚡ Reduced AWS infrastructure costs from $7,000/month → $200–250/month by migrating a multi-tenant data platform to a fully serverless architecture (96%+ cost reduction)
⚡ Cut API latency from 800ms → 120ms using Lambda and caching strategies
⚡ Built a React Native + AWS backend handling large-scale daily survey data with end-to-end security (Cognito, DynamoDB, S3, BigQuery)
→ FREE 30–60 min consultation — architecture review, cost audit, or new project scoping.
WHAT I BUILD
① Node.js Backend & AWS Cloud
Scalable APIs, serverless architecture, and event-driven systems built on AWS Lambda, API Gateway, SQS, SNS, EventBridge, Step Functions, DynamoDB, S3, Cognito, and CloudWatch. I design for performance, security, and cost — not just functionality. Migrated systems have saved clients thousands per month.
② React Native Mobile Apps
Cross-platform iOS & Android apps with real-time features, AWS-backed APIs, push notifications, and clean native-like UI. Full end-to-end delivery — from UI to secure backend integration. Live on the App Store & Google Play.
③ React & Next.js Web Apps
Full-stack web applications and SaaS dashboards using React.js and Next.js. Multi-tenant auth, Stripe billing, real-time data, admin panels, and server-side rendering. Built for performance and scale.
④ GCP Backend Systems
Event-driven microservices using Firestore, Pub/Sub, BigQuery, and Cloud Functions. Including Firestore → BigQuery analytics pipelines built with Pulumi IaC.
⑤ DevOps & Infrastructure as Code
CI/CD pipelines, Docker, GitHub Actions, AWS CodePipeline, Terraform, Pulumi, and Serverless Framework. Clean deployments with monitoring, security, and zero-downtime releases.
CASE STUDIES
Multi-Tenant Serverless Data Platform — AWS
Problem: Client paying $7,000/month on server-based infrastructure for a multi-tenant data orchestration platform.
Solution: Redesigned and migrated the entire system to AWS serverless — Lambda, API Gateway, DynamoDB, SQS, S3, with event-driven pipelines and a React admin dashboard.
Result: Monthly AWS cost dropped from $7,000 → $200–250. 96%+ cost reduction.
React Native Survey & Rewards App — Stahili
Problem: Needed a scalable, privacy-focused mobile app handling large volumes of daily survey data with secure backend connectivity.
Solution: Built end-to-end — React Native frontend (TypeScript, Redux) + AWS serverless backend (Lambda, DynamoDB, S3, Cognito, BigQuery).
Result: Live on Google Play. Smooth, scalable, and data-secure for thousands of daily active users.
