Senior Backend Engineer · Lahore, Pakistan
Backend systems that never page you at 3 AM.
10+ years designing scalable backend systems — Node.js/TypeScript, Django REST Framework, distributed task orchestration across Celery, Bull/Redis, RabbitMQ, AWS Batch and SQS, and cloud infrastructure on AWS spanning Fargate, CloudFront and ElastiCache. Currently the lead backend architect on a production clinical SaaS platform shipping multiple releases a day.

Experience
Ten years, one thread: decouple the heavy work.
- Lead backend architect for Project XXXXX, a production SaaS platform — 273+ backend PRs over 16 months across active clinical deployments, multiple releases a day.
- Designed a multi-account AWS Organization (Dev, Staging, Prod under one Workloads OU) with centralized logging, security and monitoring accounts, SCP-enforced governance, IAM Identity Center SSO and no direct SSH access — Session Manager only.
- Designed a multi-queue Celery architecture on RabbitMQ and SQS, fully decoupling heavy processing jobs from the web request cycle across four independent queues.
- Built AWS infrastructure end-to-end: S3 structured data lake, CloudFront CDN, ElastiCache/Redis for signed URL caching, and SQS for async task queuing.
- Migrated long-running synchronous jobs to AWS Batch and Fargate-managed compute, improving pipeline reliability and removing blocking on heavy background tasks.
- Built the GitHub → CodePipeline CI/CD flow — Trivy and Gitleaks security scans, ECR image builds, rolling ECS deploys with health checks and auto-rollback, and manual approval gates before production.
- Also set up Jenkins CI/CD pipelines with Slack deployment notifications, and implemented SSE-based progress updates for long-running jobs without polling overhead.
- Led backend development for Braces on Demand, an orthodontic clinical platform built in Node.js and TypeScript, owning API design and service architecture.
- Defined and enforced TypeScript standards across the backend team — strict typing, interface contracts, modular services.
- Owned production health on AWS EC2: debugged Node.js performance bottlenecks and memory leaks behind an Nginx reverse proxy.
- Led a team of up to 10 engineers on ProtoSphere, a $250K+ Unity3D collaboration platform for virtual meetings and e-learning on Mac, Windows and WebGL.
- Delivered the Global Rollout System for Samsung — a WebGL tool automating retail shop design with 3D walkthroughs and material reports.
- Designed a high-performance C# cache system that became ProtoSphere's core framework.
- Focused on C# architecture, performance optimization and cross-platform delivery.
- Shipped Asterix & Friends (Android, iOS, WebGL) and Life in Willowdale: Farming Adventures (PS4, PS5, Switch, Steam).
- Shipped Farm Day Village, a social farm game with live-service features.
- Developed multiplayer game prototypes with component-based architecture in C#.
