How Builder Prime's iOS app supports offline clock-ins and estimates

Builder Prime is a strong example of mobile product engineering for real-world field conditions: offline clock-in and clock-out, estimate editing, queued sync, and ID mapping that keeps work moving when connectivity is unreliable.

Maintaining Boon across iOS, Android, and a Java backend

Reviews

What product teams say after shipping together

Reviews from Workmax, Biomeme, Babylist, and Ruvio highlight dependable delivery, native mobile depth, thoughtful product input, and collaboration that lasts beyond a launch.

Russell Hanson

CTO at Workmax

Sergey has done a tremendous amount of work for our company over several years and is very dependable. He is very skilled in mobile native iOS development. He built a complete product for us from the ground up, added features to the product through several versions, and helped maintain the product through several versions. He really felt like he was just part of our engineering team and we treated him as such. I would not hesitate to hire him at all and most likely will hire him again in the near future on other projects.

Max Perelman

CEO at Biomeme

It was such a pleasure to work with Sergey and his team. He is on call 24*7 and adheres to every request we made in spite of us deviating from our original product spec. In addition to a strong technical skill set, Sergey also makes very good suggestions on the UI and UX front. I would rehire Sergey in a heartbeat and if things go right, I may just hire this guy full time.

Noah Solnick

Director of Software Engineering at Babylist

I worked with Sergey for over a year on a project to rebuild our iOS and Android apps. Sergey was excellent as an individual contributor as well as manager of two additional remote devs on the team. We released multiple features on a monthly basis with minimal challenges. Sergey was reliable, communicative, and a pleasure to work with.

Ruvio / Layzeer Scanner

Eduard Friesen

Ruvio and Layzeer Scanner

Working with Sergey felt like adding a real product partner to our team. Across both Ruvio and the Layzeer Scanner app, he helped turn complex finance and document workflows into mobile experiences that are dependable, clear, and genuinely pleasant to use. He moves quickly, communicates well, and stays thoughtful when scope changes or new ideas appear midstream. I would gladly work with him again on future products.
