Web and mobile app development that holds up under real users

Web applications, portals and iOS and Android apps that load fast, look right and pass accessibility audits. Built in Sarajevo by senior engineers for companies in Bosnia, Germany and the EU.

A customer-facing product is judged in the first three seconds. If the page is slow, the form breaks on a phone, or a screen reader cannot get past the menu, the user leaves and your support inbox fills up. We build web and mobile apps that are measured against those things from the first sprint: load time, correctness on real devices, and WCAG 2.2 accessibility.

Web development and mobile app development are the core of what Elevate Solutions does from Sarajevo for companies in Bosnia, Germany and the EU. The team is senior only, and the engineers you meet in discovery are the ones who ship the product. We also run our own web products, PatchBee and DesAIgner, which keeps us honest about performance, uptime and what users actually click.

What we build

We build the product your customers, partners or employees open every day: web applications and portals, native-feeling iOS and Android apps, and the design system that keeps all of them consistent. Next.js is our default for the web, Angular when your team already runs on it, React Native for mobile, and Tailwind for styling. One codebase per platform, shared components where that is honest, and no framework chosen for its novelty.

  • Web applications and customer or partner portals with authentication, roles and billing
  • iOS and Android apps in React Native, published to the App Store and Google Play
  • Design systems and component libraries your team can keep building on
  • WCAG 2.2 accessibility, tested with keyboards and screen readers, not just a checker
  • Performance work on existing apps: Core Web Vitals, bundle size, slow queries
  • Front ends for existing APIs and back-office systems

How we work

Every app runs through the same four phases. Discover takes 1 to 2 weeks: workshops on users, flows and constraints, a written brief and a fixed-price estimate for the next phase. Design produces the architecture, the UX and a clickable prototype you can put in front of real users before a line of code exists. Build runs in sprints with a weekly demo on staging, direct communication with the engineers and no black boxes. Elevate starts at launch: we monitor Core Web Vitals, crashes and app store reviews, fix what hurts and keep improving on a roadmap we review with you. The team stays after go-live.

Discover. Workshops with your team to define scope, risks and what success means. You get a written brief and a fixed-price estimate for the next phase.

What you get

You get a product that works on the devices your users actually own, and everything needed to keep it that way. Code, pipelines, store accounts and design files are yours, documented well enough for your next hire to continue without us.

  • A clickable prototype and a technical design before Build starts
  • Source code in your repository with automated tests and CI/CD to staging and production
  • App Store and Google Play listings set up under your own accounts
  • An accessibility report against WCAG 2.2 AA with the fixes already applied
  • Performance budgets and monitoring, so regressions show up before users complain
  • Design system and Figma files handed over with the code

Who this is for

This service fits companies whose product or customer relationship lives on a screen, and whose current app is either too slow, too hard to change, or not there yet. It is less useful if a well-configured website builder already does the job, and we will say so.

  • Companies in Bosnia, Germany and the EU launching a customer portal, marketplace or SaaS product
  • Businesses whose mobile app needs a rebuild because nobody can maintain the old one
  • Public and regulated organisations that must meet WCAG 2.2 accessibility
  • Founders with a validated idea who need a senior team to ship version one

Technologies we use

Frequently asked questions

Start with the question of where your users are and what the app needs from the device. Most B2B products do well as a responsive web app, which is cheaper to run and update. We recommend React Native when you need push notifications, offline work, camera or store presence. We settle this in Discover, with numbers.
