Web applications, mobile apps, and desktop software — delivered on time using the technologies your business needs to grow.
We keep things transparent at every stage — you always know exactly where your project stands.
We dive deep into your goals, users, and constraints. You leave with a clear plan, timeline, and cost estimate.
Our designers build wireframes and high-fidelity prototypes. You approve before a single line of code is written.
We develop in two-week sprints with live demo access. You see progress in real time and give feedback that matters.
We handle production deployment and stay on for post-launch support. Your product is never left without a safety net.
From first-line concept to production-ready product — we cover the full engineering stack.
Full-stack web applications built with Laravel, Django, ReactJS, Angular, and TypeScript. Scalable, secure, and SEO-ready from day one.
Cross-platform iOS and Android apps built with React Native and Flutter. One codebase, two stores, zero compromise on performance.
Native and cross-platform desktop apps using Qt, C++, and Python Tkinter. Built for performance-critical industries including vision and automation.
Research-driven design that puts your users first. Wireframes, prototypes, and pixel-perfect Figma hand-offs your engineers will love.
Real-time object detection, image processing, and analytics powered by OpenCV and Python. Trusted for industrial and healthcare applications.
Docker, Linux server setup, CI/CD pipelines, and WebRTC infrastructure. We make sure your app is always fast, always up, always secure.
Manual and automated testing so bugs get caught before users do. We integrate testing into every sprint, not just the end.
RESTful and GraphQL APIs built for reliability and developer experience. Clean documentation, versioning, and rate limiting included.
Monthly retainer plans for ongoing monitoring, bug fixes, dependency updates, and feature enhancements. We stay with you after launch.

We're hiring — get in touch20+ clients across four continents. Here's what they say about working with BigInteger.
★★★★★BigInteger delivered our health platform on time and within budget. The team's attention to compliance requirements was exceptional.
★★★★★The property valuation portal handles over 500 valuations a day without a hiccup. The GDPR compliance work saved us months of legal headaches.
★★★★★BigInteger is different — they challenge your assumptions and push back when something won't work. That's exactly what you want in a technical partner.
★★★★★Our training LMS went from zero to 10,000 users in three months. The Spring/Java backend handles the load effortlessly. Communication on Slack was excellent throughout.
★★★★★The OpenCV pipeline processes 30 frames per second on our edge hardware. Two other vendors couldn't get past 8fps. BigInteger figured it out in week one.
★★★★★We launched our digital content marketplace six weeks ahead of schedule. The React front-end is fast, the Laravel API is rock solid. BigInteger treated our deadline like their own.
