Microservices architecture that scales with your business from startup to enterprise
Dev Entity builds web products that are practical to launch and realistic to maintain. We work with startups, service businesses, and growing teams that need more than a template: they need fast pages, structured data, secure accounts, dashboards, integrations, and backend logic that supports real operations.
Our web development process combines product planning, interface design, frontend engineering, backend development, database design, cloud deployment, QA, and post-launch support. Whether the project is a marketing site, customer portal, SaaS product, booking platform, or internal admin system, we keep the build focused on performance, clarity, and long-term ownership.
Many companies start with a marketing site and quickly need portals, dashboards, payments, content workflows, integrations, and admin tools. We plan web architecture so the first release is fast and manageable, while still leaving a clean path for future product features.
We build web applications around the way your users, staff, partners, and customers actually work. That can include role-based access, reporting, file handling, booking flows, approval processes, inventory workflows, customer portals, and internal tools that replace spreadsheets or disconnected systems.
A web product should not force a tradeoff between speed, discoverability, and engineering quality. Our Next.js and React builds use server rendering, structured metadata, optimized assets, clean component boundaries, API planning, and deployment practices that support long-term maintenance.

We start by mapping user roles, content needs, workflows, integrations, data models, and hosting requirements. This gives the project a clear technical direction before development begins and reduces the risk of rebuilding core features later.
Our team builds responsive interfaces, API layers, databases, authentication, dashboards, and admin panels as one connected product. We keep frontend and backend decisions aligned so the user experience stays fast, reliable, and easier to extend.
After release, we support monitoring, bug fixes, dependency updates, Core Web Vitals improvements, feature additions, and infrastructure changes. This keeps the web application stable while your team learns from real users and business data.
Dev Entity offers custom web application development, Next.js and React platform development, API and backend development, e-commerce web development, SaaS platform development, CMS integration, and web performance optimization.
A simple marketing website or landing page takes 2–4 weeks. A web application with authentication, dashboards, and API integration takes 2–4 months. Complex SaaS platforms with multi-tenant architecture, billing, and advanced features take 4–8 months.
Web development starts from $5,000 for a simple brochure site. Custom web applications range from $20,000 to $80,000. Full SaaS platforms and e-commerce systems range from $50,000 to $300,000+ depending on features and integrations.
We primarily use Next.js and React for frontend, Node.js and Python for backend APIs, PostgreSQL and MongoDB for databases, and cloud providers including AWS and Google Cloud for infrastructure and deployment.
Yes. We offer post-launch support packages covering bug fixes, dependency updates, performance monitoring, feature additions, and infrastructure management so your web product stays reliable after release.
