Message

At LONGWApps (Pvt) Ltd, I develop backend systems and cloud-native applications, contributing to architecture decisions and supporting production systems.

On Galumatires, I led backend development for e-commerce features and integrations, including REST APIs, payment and shipping services, and product and order synchronization workflows.

I also designed backend architecture for MergeFirst, a serverless, event-driven project management platform using Node.js, GraphQL, AWS Lambda, and WebSockets.

Across my work, I’ve developed SaaS and business applications, optimized databases, managed deployments, and supported junior engineers through code reviews and technical guidance.
