Portfolio & Engineering FAQs

Common questions about our custom software development services, tech stack, and client NDA projects.

What types of custom software applications does DevApps Technology build?

DevApps Technology engineers enterprise web applications, two-sided service marketplaces, SaaS platforms, native iOS and Android mobile apps, and offline-first desktop software (ERPs, WMS, POS, HMS). We build tailored solutions for Healthcare, Construction, E-Commerce, Logistics, and Enterprise sectors.

Does DevApps Technology sign Non-Disclosure Agreements (NDAs) for corporate projects?

Yes, 100%. We routinely sign strict Non-Disclosure Agreements (NDAs) and IP Assignment Agreements before reviewing sensitive codebase architecture or enterprise business requirements. Many of our desktop ERP, LIMS, and terminal operating systems operate privately under NDA.

What core technology stacks do you specialize in for US client projects?

Our core stack includes Next.js 15, React 19, TypeScript, Node.js, Python, PHP/Laravel, C#/.NET Core, Tauri (Rust), Electron, Android (Java/Kotlin), Flutter, PostgreSQL, MongoDB, SQLite, and AWS cloud infrastructure.

How do you handle offline resilience and real-time synchronization in desktop software?

We build hybrid desktop applications using SQLite local transaction journals with background delta sync (SignalR, WebSockets, or gRPC). When network connectivity drops, users continue working without data loss, and changes automatically push to central PostgreSQL/SQL Server databases upon reconnection.

What is your typical project delivery methodology and timeline?

We follow an Agile development process with 2-week sprint cycles, continuous CI/CD deployments, and automated testing pipelines. MVP web and mobile applications typically launch in 6 to 12 weeks, while full enterprise ERPs range from 12 to 24 weeks depending on scope.
