RAG vs Fine-Tuning: Choosing the Right LLM Approach for Your Product
Both RAG and fine-tuning improve LLM performance on your specific use case — but they solve different problems. Here's how to choose.

THE CHALLENGE
Sound familiar?
- Your web app is slow — users bounce before they engage
- Your Next.js app is a mess of 'use client' that defeats SSR
- You need AI features in the web app but lack integration expertise
- Your API is unreliable and the frontend is a patchwork of workarounds
- You have no CI/CD pipeline — deployments are manual and risky
OUR APPROACH
How we solve it
We build Next.js web applications with proper App Router architecture, TypeScript throughout, and AI integrations designed in from the start. Lighthouse 95+, REST or GraphQL APIs, cloud deployment with CI/CD — delivered as a complete system.
What you receive
- Next.js App Router application with TypeScript
- REST or GraphQL API with full documentation
- Database schema, migrations, and ORM setup
- CI/CD pipeline with GitHub Actions
- Cloud deployment to Vercel, AWS, or GCP
- Lighthouse 95+ performance audit
- Unit, integration, and E2E test coverage
OUTCOMES
What you walk away with
01
Web application in production with Lighthouse 95+ scores
02
Fast, SEO-ready pages with proper SSR/SSG architecture
03
AI features that load fast and work reliably at scale
04
Clean TypeScript codebase your team can extend
05
Zero-downtime deployments via CI/CD pipeline

Next.js App Router gives you SSR, SSG, ISR, server components, and streaming in one framework — with TypeScript, API routes, and excellent DX. It is the right default for most web application projects.
It means your pages load fast on real mobile connections, pass Core Web Vitals (LCP, CLS, FID), and pass Google's performance thresholds. This directly affects search ranking and conversion rates.
Yes. We build the full stack — Next.js frontend, REST or GraphQL API, database schema, and cloud infrastructure. You get a complete system, not just a frontend.
