Frequently asked questions
How long does it take to build a web app with Next.js?
It depends on complexity. An optimized landing page can be ready in 1-2 weeks. A platform with authentication, dashboard, and database takes 4-8 weeks. I always start with a technical audit to define scope and deliverables.
Why Next.js and not another framework?
Next.js offers the best combination of performance, SEO, and developer experience. Its hybrid rendering system (SSR/SSG/ISR) ensures each page is served in the most efficient way for Google and users. Plus, its ecosystem with Vercel guarantees fast, reliable deployments.
Can you migrate my current site to Next.js?
Yes. I handle migrations from WordPress, React SPAs, Angular, and other frameworks. The process includes a pre-migration SEO audit, URL mapping, 301 redirects, and post-migration validation to preserve organic rankings.
Can the chatbot connect with my CRM or database?
Yes. I design integrations with HubSpot, Salesforce, Firestore, PostgreSQL, and REST/GraphQL APIs. The chatbot can query and write data to your systems securely.
How secure is the implementation?
Security is a design principle, not an add-on. I implement JWT authentication, input sanitization, rate limiting, and sensitive information is never sent directly to the LLM without preprocessing.
How much does it cost to maintain an AI chatbot?
Operational costs depend on conversation volume and the AI model used. I design architectures that optimize token usage with caching and precomputed responses to keep costs low without sacrificing quality.
What visualization libraries do you use?
I work with Recharts, D3.js, Chart.js, and Plotly depending on project needs. For BI dashboards I also have experience with Power BI and DAX for complex queries.
Can the dashboard consume real-time data?
Yes. I implement WebSocket connections, Firestore real-time listeners, and optimized polling. The architecture is designed so data updates without page reloads.
Can I add new metrics later?
Absolutely. I design dashboards with modular architecture: adding new cards, charts, or sections is as simple as configuring a new component. The data structure is extensible by design.
