Reach out if you need help shipping a mobile app, improving a web platform, shaping an AI workflow, or steadying the backend systems behind the product before delivery gets more expensive.
Choose a starting point
These landing pages are a faster route when you already know whether the work is mainly AI, mobile, or web and backend.
AI
For teams building AI-assisted workflows, generation, scoring, moderation, or analysis into a product people actually need to trust.
Mobile
For teams shipping iOS and Android products that need strong release discipline, offline support, smoother onboarding, or steadier product delivery.
Web + Backend
For SaaS, marketplace, internal, and operational products that need a clearer system underneath the interface before delivery gets more expensive.
Best first step
If you already know the product, the team shape, and what feels stuck, the hosted brief is the cleanest way to start. It gives enough context to reply with something useful instead of a vague “tell me more.”
Prefer email?
Email is still great when you want to keep it simple. A few lines about the product, the team, the timeline, and what is getting stuck is enough to get the conversation moving.
Good fit
You already have a product and delivery has started to feel heavier than it should.
You need senior implementation help without adding a large permanent team right away.
The product touches mobile, web, backend, AI workflows, or all of the above.
You care about shipping speed, but not at the cost of future maintainability.
What happens next
You send a short brief or email with the product, team, and where things feel stuck.
We reply with honest thoughts on fit, follow-up questions, and whether a call or deeper look makes sense.
If there is a fit, we agree on the next concrete step — no drawn-out sales process.
Useful to include
What the product does and who it is for.
What has already been built and which surfaces are involved.
The timeline pressure, team shape, and what success should look like.
Reviews
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.
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.
Still deciding?
A brief note is enough if you're still figuring out scope. If there's a fit, we'll tell you. If not, you'll at least leave with a clearer next step.
