Services
Transforming ideas into powerful digital solutions with modern technologies and best practices for mobile and web development.
Mobile Apps
Cross‑platform React Native apps with native performance and polished UX: offline‑first data, deep links, push notifications, secure auth, and smooth 60fps interactions. Release automation, crash analytics, and feature flags included for fast, safe iteration.
Web Applications
Modern Next.js experiences with SSR/ISR, accessibility by default, and Core Web Vitals in the green. Scalable component systems, robust routing/data‑fetching, and SEO‑ready foundations that load fast and convert.
Backend APIs
Robust REST services in Node.js & Go with clean architecture, input validation, RBAC, caching, and rate limiting. Observability (logs/metrics/traces), automated tests, and predictable performance backed by PostgreSQL.
Full‑Stack Solutions
End‑to‑end delivery—from product discovery and data modeling to deployment. Supabase + PostgreSQL, Dockerized pipelines, CI/CD, and zero‑downtime releases. Documentation and handoff that teams can build on.
