From customer-facing web platforms to cross-platform mobile apps, we design and engineer products people enjoy using — backed by secure APIs and infrastructure that hold up under real-world load.
Built by engineers who work inside your business — learning how your team works and delivering results in weeks.
How it worksFast, accessible, SEO-friendly applications built with React and Next.js, from customer dashboards to marketplaces.
iOS and Android apps from a single React Native or Flutter codebase, with native modules where performance demands it.
User research, flows, wireframes and polished interface design, validated with clickable prototypes before development.
Secure, well-documented APIs, authentication, payments and real-time features that power your web and mobile clients.
Installable, offline-capable web apps when you need mobile reach without app-store overhead.
App Store and Google Play submission, crash monitoring, OS updates and continuous improvement after launch.
Our engineers start by spending time with the people who'll use what we build. You see your first improvement working early, and it gets better every week after. Once it's live, the same people stay to support it — or hand it over cleanly.
Astralogic's founder needed someone to take care of the technology from start to finish. We handled everything — planning, servers, building and launching — so the founder could focus on the business.
As a non-technical founder, I was worried about managing development. Portabill acted as my CTO, handling everything from server setup to deployment seamlessly.
Straight answers about how we work. If yours isn't here, ask us directly.
For most business and consumer apps, cross-platform (React Native or Flutter) delivers near-native experience at significantly lower cost. We recommend fully native development only when an app depends heavily on device-specific capabilities or extreme performance.
Yes. We handle UX research, wireframes and visual design, and test clickable prototypes with you before development starts — or work from your existing design system.
Yes. We prepare store listings, manage builds and certificates, handle review feedback and publish releases under your developer accounts.
We offer ongoing maintenance covering OS and dependency updates, crash monitoring, performance improvements and new features.
Typical price ranges by project type, the factors that really drive cost, the ongoing costs people forget, and how to compare custom software with off-the-shelf tools.
OutsourcingEverything international buyers should know before hiring an Indian software team: engagement models, costs, how to evaluate companies, contracts and IP, payments, time zones and red flags.
