A senior product & engineering studio. We take ideas from whiteboard to App Store — built clean, tested hard, shipped on time.
One senior team owns your product end to end — design, build, ship, and scale. No handoffs, no surprises.
Native iOS & Android plus cross-platform builds with React Native and Flutter — fast, fluid, and built to scale.
Dashboards, SaaS platforms, and progressive web apps using React, Next.js, and Node — engineered for real load.
Research, prototypes, and design systems. Interfaces that feel obvious to users and unmistakably yours.
APIs, microservices, and real-time infrastructure on AWS, GCP, and Azure — reliable and observable.
Smart features powered by modern LLMs and custom models — assistants, automation, and recommendations.
CI/CD pipelines, monitoring, and post-launch iteration driven by what your users actually do.
We map your business, users, and goals — then scope requirements and risks before any code is written.
Wireframes become clickable prototypes. We validate ideas early, while changes are still cheap.
Two-week sprints, live demos, clean code, and automated testing at every checkpoint.
Store submission, production deploy, analytics — then we iterate based on real data.
Telemedicine & patient management app, 50k+ active users.
Real-time analytics platform with custom charting and live data feeds.
Cross-platform shopping app with AR try-on and AI recommendations.
Fleet tracking and route optimization dashboard for 200+ vehicles.
We pick tools for the long run — performance, reliability, and a codebase your team can own.
Fiter is a product-minded engineering studio based in Dnipro, Ukraine. We work with founders and established companies to build apps that move the needle — not just tick a box.
We don't just write code. We think about your users, your business model, and where you're headed — then build accordingly.
"They shipped two weeks early and the polish was extraordinary. Our users noticed the quality right away."
"Working with Fiter felt like having a co-founder who happened to be a brilliant engineer. They pushed us — for the better."
"The backend they built handles millions of events a second without flinching. Exceptional technical depth."
