"Sahbaan share his ideas about the development I asked and delivered exactly what I requested and he is doing everything he can to make the client satisfied. The deliverable is working perfectly and he even suggested to more than I asked but it was a little early to my product" "We hired Sahbaan to write the first and second of eight phases that will result in the MVP (minimum viable product) of SST available as SaaS on AWS. SST is written in Java using Spring Boot. Sahbaan was professional and a pleasure to work with. He asked intelligent questions, made valuable suggestions, endured our brutal quality assurance cheerfully, responded quickly to the issues we uncovered, and kept us informed. We were pleased with his work, plan to use him for all the other phases, and recommend him to others." "Working with this developer was a game-changer. They showed exceptional skills and expertise, transforming our vision into a practical, user-friendly software solution. Their ability to grasp complex requirements and translate them into effective functionalities was truly remarkable. Their dedication, professionalism, innovative approach, and keen eye for detail made the whole development process a seamless experience. This developer is a rare gem in the software industry and we couldn't recommend them more highly. Truly a five-star experience!"

I have been awarded Software Engineer, and Full Stack developer over the years, usually as a part of a great team. All these experiences have been very useful for several new companies. I work in either of these roles: 1) Software Engineer: As a Software Engineer of your Business, all you need to do is give me your business information and a rough product or service plan. I will think through how to get the technical parts of the job done. Good match with non-technical business owners or stakeholders who wish to automate and streamline their business processes. I can help with concept development, prototyping, product development, MVP evaluation, SAAS development, and ERP and I tend to suggest practical strategies for rolling out your product to the intended market. 2) Full Stack Developer: I help your team to react to operational excellence with all the background I have in Software development, scientific research, and innovation.
