Job Success
Lahore, Pakistan - 10:21 pm local time
Over 12+ years, I've shipped backend systems across EdTech, HealthTech, FinTech, and e-commerce - handling architecture, performance, and production reliability end to end.
What I help clients with:
- REST and GraphQL APIs built with NestJS, Express, and Node.js
- Scalable microservices and event-driven architectures
- PostgreSQL and MongoDB database design, optimization, and migrations
- Redis caching, job queues (BullMQ), and background processing
- Authentication, authorization, and multi-tenant SaaS patterns
- Third-party integrations (Stripe, Twilio, OpenAI, Claude API)
- Cloud deployment on AWS and Docker-based CI/CD pipelines
Recent work includes building the backend infrastructure for an assistive EdTech platform serving thousands of families, with a focus on offline-first sync, secure data handling for minors, and high reliability on resource-constrained devices.
Previous roles include Principal Engineer at Confiz/Systems Limited and CTO at GeeksForce Technologies, where I led backend teams and architected systems at scale.
I work best with product teams and founders who want a backend they can trust - clean code, solid tests, clear documentation, and honest communication.
If that sounds like what you need, let's talk.
