Yes — I'm currently taking on freelance and contract projects alongside my full-time role as a Senior Software Engineer, and I work with clients outside Pakistan. The fastest way to start is the contact form below; I reply within 24 hours.

Full-stack web applications, Next.js front ends, Node and NestJS APIs, and performance audits on existing apps. I work best on products that need to hold up in production — real traffic, real data, real deadlines — rather than throwaway prototypes.

JavaScript and TypeScript end to end. React and Next.js on the front, Node, Express and NestJS on the back, with MongoDB or SQL for data and AWS (EC2, ECS, S3, Amplify) for infrastructure. I also work with GraphQL, React Native and Python/Flask where a project calls for it.

I'm based in Gulberg II, Lahore, PK, on Pakistan Standard Time (UTC+5). That gives me a full working overlap with Europe and the Middle East, and mornings overlap with US East Coast afternoons. I work remotely with teams anywhere.

It depends on scope, timeline and how much ownership you need me to take. The contact form has budget bands so we can start in the right ballpark — tell me what you're building and I'll come back with an honest estimate rather than a generic rate card.

A focused front end or API build usually runs 4–8 weeks. Full products with auth, payments, dashboards and deployment typically run 3+ months. Performance audits are much shorter — often a week to diagnose and a week to fix the worst offenders.

Yes, and it's a lot of what I do. I've migrated unmaintainable Express services to structured NestJS modules, lifted Lighthouse scores on slow marketing sites, and picked up half-finished products. I'll read the code first and tell you honestly whether refactoring or rewriting is the better call.

Over 5 years, starting in 2021. I'm currently a Senior Software Engineer at Ragzon Solutions in Lahore, and previously worked at Fastech and Crave Tech. Along the way I've shipped for LegalTech, e-commerce, EdTech and SaaS products.
