“Khaliq designed a complex web scraping and presentation interface that allowed me to save several hours per day. Over time I've worked with Khaliq on upgrades to this tool and it's been a pleasure each and every time. If more freelancers on Upwork had this level of skillset and work ethic, there would be a lot more happy clients. I highly recommend hiring for any of these areas of expertise.”
— Scott O.
“I hired Khaliq to create some web scrapes. He was very patient with me while I described exactly what I wanted and even offered suggestions to make it better. The turn around time on the projects are usually ahead of schedule and exactly what I asked for. I will continue to use Khaliq for any web scraping related projects. I highly recommend.”
— Joseph P.
“I've worked with Khaliq on multiple projects and he has always exceeded my expectations, delivered on time and within budget. I would highly recommend Khaliq to anyone that needs helps with tasks related to Data.”

I help companies build the systems that keep their business running — reliable backend software, intelligent automation pipelines, and data infrastructure that scales. With 500+ projects delivered and years of production-grade engineering experience, I bring the kind of depth that turns a working prototype into something you can actually depend on.
Whether you need a robust API, an end-to-end data pipeline, or a workflow automation system that removes human bottlenecks, I design and ship solutions that are clean, documented, and built for the long term.
