About
Crafting Digital Experiences

Junaid
I'm a Full-Stack Software Engineer and Solution Architect with 6+ years of experience designing and delivering production-grade, cloud-native applications. I specialize in TypeScript, React/Next.js frontends, and Node.js/Nest.js backends — with deep expertise in distributed system design, multi-tenant SaaS platforms, event-driven microservices, serverless architectures, and real-time systems.
My engineering focus is on systems that are built to scale and last. From AI document processing pipelines achieving 95% extraction accuracy on 10,000+ government PDFs, to a YouTube revenue forecasting SaaS with a 7-step async ML pipeline and multi-layer Redis caching — I architect solutions around reliability, performance, and long-term maintainability. I thrive in remote-first, cross-timezone environments and bring strong technical leadership, clear communication, and end-to-end ownership to every engagement.
