We build mobile apps with meaning.
We’re Proffi, a Ukrainian mobile development studio passionate about building purposeful digital products. From bold app ideas to polished releases — we help businesses bring their vision to life through thoughtful design, clean code, and an agile mindset.
But we’re not just developers. We’re problem solvers, product thinkers, and creative partners who care about what your app does — not just how it looks.
Our Story
Proffi was founded with one clear belief: great apps are born at the intersection of usability, technology, and heart.
In a world flooded with generic software and copy-paste solutions, we wanted to build something different. A studio that listens, thinks, and builds with intention.
We started small — a tight-knit team of friends and freelancers — and quickly grew into a trusted partner for startups, founders, and businesses looking to turn ideas into intuitive mobile experiences.
Despite our growth, we’ve never lost the thing that made us stand out: our energy, flexibility, and obsession with quality.
What We Do
We specialize in custom mobile development, working with both iOS and Android — whether you need an MVP to test your idea or a full-featured app to scale your business.
We cover the full cycle:
- Product strategy & idea validation
- UI/UX design that feels natural
- Native & cross-platform development
- QA and performance optimization
- Post-launch support and updates
Our Approach
We treat every project like it’s our own.
No bloated corporate processes. No copy-paste templates. No disappearing after delivery. We’re transparent, fast-moving, and committed to long-term collaboration.
When you work with us, you get:
- A hands-on team who actually cares
- Clear timelines and honest communication
- Full visibility into the process
- A product that works — for users and business goals
Why Ukraine?
We’re proud to be part of Ukraine’s vibrant tech ecosystem — one of the most resilient, creative, and fast-evolving in the world.
Despite the challenges, our spirit never breaks. We believe in building, in solving, in moving forward. Every line of code we write is powered by grit, talent, and a belief in something better.
