Modern businesses rely on digital platforms that customers interact with daily. We design and build customer-facing platforms including web applications, ecommerce and transactional systems, SaaS interfaces, and mobile applications.
Modern businesses rely on digital platforms that customers interact with daily. We design and build customer-facing platforms including web applications, ecommerce and transactional systems, SaaS interfaces, dashboards, and mobile applications that power digital products and services.
Whether it's a customer portal, a transactional platform, or a SaaS product interface — we design and build digital platforms used by customers, partners, and internal teams, built for adoption from day one.
200+ platforms shipped across industries since 2006.
Every engagement led by experienced specialists who have shipped production systems at scale.
We measure success in business results, not lines of code.
Chicago office ensures real overlap with US teams all day.
Wireframes, prototypes, and polished interfaces tested with real users before production code is written.
High-performance web platforms built with React and Next.js — fast, scalable, and maintainable.
iOS and Android apps, native or cross-platform (React Native / Flutter) depending on your requirements.
Core Web Vitals optimisation, sub-2s load times, and Lighthouse scores above 90.
Authentication, authorisation, and data protection built in from the start — not added at the end.
AWS or GCP infrastructure, CI/CD pipelines, and monitoring — reliable deployments at any scale.
A consumer health app had 50,000+ downloads but a 3.1-star rating and a codebase their previous agency had left unmaintainable. Users were churning at the onboarding screen.
We conducted a full UX and technical audit, rebuilt the core architecture, and shipped a redesigned version in four months — tested with real users throughout.
App Store rating increased from 3.1 to 4.6. Onboarding completion rate up 60%. Zero critical bugs in first 30 days post-launch.
A clear, structured process — you always know what happens next.
User journeys, wireframes, and clickable prototype tested with real users before production build.
Tech stack, CI/CD pipeline, and cloud infrastructure configured before the first feature sprint.
Iterative sprints. Real working software every two weeks, tested on real devices throughout.
Automated tests, browser compatibility, performance benchmarking, and security review before every release.
Staged deployment, monitoring, and a 30-day post-launch support period.
We've delivered this type of work across a range of sectors — bringing domain context, not just technical execution.
Patient engagement apps, wellness platforms, and health tracking products.
Shopping apps, loyalty platforms, and in-store mobile experience tools.
Mobile banking interfaces, expense tracking, and client-facing fintech apps.
Driver apps, field service tools, and real-time tracking for operations teams.
Client portals, partner platforms, and internal enterprise mobility solutions.
Customer portals, ecommerce platforms, SaaS interfaces, transactional systems, mobile apps (iOS and Android), and progressive web apps. We focus on products that are core to your business — the ones your customers and partners use every day, not throwaway marketing sites.
An MVP typically takes 8 to 16 weeks. A full production-grade platform with multiple modules takes 4 to 9 months. We deliver working software every 1 to 2 weeks, so you see progress continuously instead of waiting for a big-bang launch.
Both. We use native (Swift, Kotlin) when you need maximum performance, deep platform integration, or offline-first behaviour. We use React Native or Flutter for cross-platform when speed-to-market and cost matter more than the last 5% of native polish. We help you pick based on your actual constraints.
A focused MVP starts around US$35,000. A full SaaS interface or B2B platform typically runs US$75,000 to US$250,000 depending on scope. Mobile apps with a backend usually fall between US$60,000 and US$180,000. Get a working range at zansys.com/estimate.
Yes — most clients move into a maintenance and growth retainer after launch. We handle bug fixes, OS updates (iOS, Android), security patches, performance optimisation, and ongoing feature work. Retainers typically scale with the size of the platform.
We do both. Our team includes product designers and UX researchers as well as engineers. For most clients we run discovery, design, and engineering in one continuous workflow rather than handing off between separate teams.
