From the founders we've shipped with.

Every review is from a real founder at a real product.

Jacob recently performed a security review for me on my app, CaseWyze. I'll be honest, I wasn't exactly sure what to expect going into it, and I was hoping it wouldn't just be a generic, surface-level review full of fluff. It absolutely was not. His review was detailed, practical, and directly useful. He identified real security concerns, explained why they mattered, and gave clear recommendations that I could actually take action on. When you are building an app that stores customer data, business data, case information, documents, or anything sensitive, security cannot be an afterthought. Jacob was prompt, professional, and went beyond my expectations. After I made some of the changes he recommended, I asked him to briefly review them, and he did so without hesitation.

I came to Jacob after another developer had left my project in bad shape — riddled with issues and far from working. Jacob jumped in immediately, diagnosed and fixed problem after problem, and delivered a product that has worked flawlessly since his very first fix. His speed, skill, and reliability turned a frustrating situation around completely. I wouldn’t hesitate to work with him again.

Jacob is incredibly easy to work with. Not only has he met every milestone and deadline, but Jacob has always taken the time to be thorough in his work and is sure to provide documentation and training where applicable. Jacob has become a trusted resource and partner for Workforce Energetics.
Jacob rebuilt Lotify, a dealer to dealer second hand car marketplace, from a no code prototype into a production ready stack using Vercel, Supabase, and Next.js, while integrating Claude Code into the development workflow. The performance and reliability improvements were immediate, and the codebase is now in a much stronger position to scale.

Jacob has been absolutely fantastic to work with, his communication style and web development knowledge are top notch. He helped me migrate two of my apps off of Base44 in a breeze.
Jacob has been amazing to work with; he has been supportive and flexible during the development of my project. From the initial brief I gave him, to the final product he has always understood what I want the product to look like and come up with some amazing suggestions to improve the UI. I would highly recommend Jacob if you need something built or migrated off another platform.

Jacob migrated a pretty complex app that was built in Base 44 for me. He is extremely skilled and knowledgeable. His communication and response times are impeccable! In addition to the migration, I hired him for ongoing support which has been the same pleasant experience! I recommended him to a friend for website development and my friend was extremely happy as well. I highly recommend Jacob!
