We build custom software— web applications, SaaS platforms, booking systems, financial tools, and enterprise dashboards — using TypeScript, React, Vue.js, Node.js, and modern cloud infrastructure. Full-stack, from database architecture to production-ready frontend, deployed on AWS, Azure, or Google Cloud with CI/CD pipelines and auto-scaling built in from day one.
Our stack is opinionated: shared TypeScript types across frontend and backend, PostgreSQL or MongoDB depending on the data model, REST or GraphQL APIs, comprehensive test coverage, and security-first architecture following OWASP Top 10 guidelines — backed by our dedicated security and compliance practice. You get clean git history, documented code, and systems that future developers can maintain without calling us. Source code is yours, always.
We’ve built systems that process real transactions, serve regulated industries, and run in production for years without critical incident. MVP in 4–8 weeks, multi-year platform with a dedicated team, or systems augmented with AI and automation — the same engineering rigour applies. Weekly demos, milestone delivery, documented handovers.
The stack
Chosen per project. Not bolted on by default.
React, Vue, TypeScript, Node.js, PostgreSQL. Frontend, backend, data, infra — owned by one team.

What we build
Operational software, from internal tools to regulated platforms.
Architecture designed for your data model, compliance posture, and the scale you'll actually hit.
Web Applications
Next.js & Nuxt Platforms
Web applications built from scratch with Next.js, Nuxt, React, and Vue. Hybrid rendering for SEO. Real-time features via WebSockets.
- Server-side rendering for enterprise SEO
- Real-time: WebSockets, live notifications, collaboration
- Headless CMS integration or custom content management
- Payment gateway integration (Stripe, PayPal, local processors)
- Progressive Web Apps that work offline

Mobile Apps
React Native Development
iOS and Android apps built with React Native. One codebase, native performance. Offline-first architecture for low-connectivity environments.
- React Native for iOS and Android simultaneously
- Native Swift/Kotlin modules when needed
- Offline-first architecture with sync
- Real-time sync with custom backend APIs
- Hardware integration: camera, GPS, biometrics
- App Store & Google Play submission and updates

Native iOS
Native iOS (SwiftUI)
Pure SwiftUI apps built to the iOS 26 standard — not React Native wrappers. CoreLocation proximity, MapKit, AI search, Siri/App Intents, Spotlight, home-screen Widgets, and WeatherKit.
- SwiftUI with iOS 26 Liquid Glass design system
- CoreLocation proximity and MapKit integration
- On-device + API AI (natural-language search)
- App Intents / Siri Shortcuts + Spotlight indexing
- Home-screen Widgets and WeatherKit
- App Store submission and TestFlight distribution

Backend Systems
NestJS & Node.js APIs
APIs and backend systems in NestJS with TypeScript end to end. Every endpoint, every schema, every business rule — built for your data model.
- RESTful APIs built with NestJS (TypeScript)
- GraphQL APIs for complex data requirements
- Microservices architecture when scale demands it
- Authentication: OAuth2, JWT, MFA, biometrics
- Third-party integrations: payments, CRM, analytics
- Real-time WebSocket servers for live features
