GilgitApp
Served as Technical Lead and Full Stack Developer for a large-scale marketplace platform built with Next.js, Node.js, React Native, and PostgreSQL.
The platform grew to 800,000+ downloads, requiring scalable architecture, structured CI/CD, production monitoring, and reliable deployments.

My approach
I don't just start coding.
Before implementation, I clarify the requirements, define the architecture, identify technical risks, and establish the database/API structure. Then I build, test, deploy, and support the product in production.
You'll get clear communication, regular progress updates, clean code, and someone who can take ownership of the entire technical stack.
Whether you need to build an MVP, launch a SaaS product, add AI to an existing application, integrate third-party APIs, or fix a production system, I can help.
Send me your requirements, existing architecture, or product idea, and I'll tell you the best way to approach it.
Cheers,
Afaq K.
