    "After reviewing 30+ candidates, You are definitely the one that stands out." Teddy Sardar, Founder, Fundred, Inc. | March 2023 🏆One-stop-shop🏆 You want to DESIGN or DEVELOP an Application for your business. (click below for more proof) 💚💚💚"I had had a few misfires with previous offshore teams and individuals. These guys have turned me around. They were flexible, responsive, fast, gave great feedback and got the job done. They have become my "go to" dev and design team." -Tony Clemendor, gift-wow.com Hello and welcome to my profile. I'm Kacper Gazda. I specialize in: 📙 ANALYSIS: Pre-Implementation analysis and research 📙 DESIGN: Efficient UI/UX design and prototyping 📙 DEVELOPMENT: Full stack Application development Front-end & Back-end 📙 TESTING: Manual and Automated testing for Your Application Most freelancers sell hours of service, not product development.

What works is focusing on bringing benefits to your users. These users will bring benefits to your business. 💚💚💚"They delivered a system which is just as effective as having 30% more people on staff!" -Jamie Jacobs, kfm247.com If you are tired of freelancers telling you how great they are, not focusing on You, then give me a shout.
