Choosing a Tech Stack for Your Business: A Practical Guide

One of the questions we get asked most often at Gravtek is: "What technology should we use?" It is a good question, and the honest answer is: it depends.

But "it depends" is not very useful on its own. Here is the framework we use.

Start with the type of product

The type of product you are building narrows the field significantly.

**Business website / marketing site**: Next.js with a headless CMS (like Sanity or Contentful) is our default recommendation. You get fast page loads, great SEO, easy content updates for non-technical staff, and a proven deployment path via Vercel.

**SaaS product with user accounts**: Next.js (frontend + API), PostgreSQL (database), Redis (session/cache), hosted on AWS or Railway. This is a solid, scalable foundation that can handle significant growth without a rewrite.

**E-commerce**: For most businesses, a well-configured Shopify store is more cost-effective than a custom build. If you need custom functionality, multi-vendor capabilities, or deep integrations, then a custom Next.js + Node.js + MongoDB stack makes sense.

**Internal tools / dashboards**: React with a Node.js backend and PostgreSQL. Keep it simple — internal tools do not need to be beautiful, they need to be fast and reliable.

Do not over-engineer for where you are

A startup with 50 users does not need Kubernetes, microservices, or a message queue. These tools solve real problems — but at scale. Choosing them too early adds engineering complexity and maintenance burden without delivering user value.

Start with a monolith (a single Next.js or Node.js application). Split it when you have a real, demonstrated reason to.

Think about your team, not just the tech

The best tech stack is the one your team knows well. A team that knows Python deeply will ship faster with FastAPI than they will with Node.js, even if Node.js is theoretically a better fit for real-time features.

If you are hiring a development agency, ask them what they build most of. Use what they are proven in.

Practical recommendations for Bangladesh-based businesses

For most Bangladesh-based businesses we work with, our default stack is:

• ·Frontend: Next.js 14+ (React)
• ·Backend: Node.js (or Next.js API routes for simpler projects)
• ·Database: PostgreSQL for relational data; MongoDB if the data model is genuinely document-oriented
• ·Hosting: Vercel (frontend), Railway or AWS (backend/database)
• ·Auth: NextAuth.js or Clerk
• ·Payments: SSLCommerz for local BDT payments; Stripe for international

This stack is mature, well-supported, and our team builds with it every day.

Summary

Choose a tech stack based on: your product type, your team's expertise, and where you are in your growth curve. Avoid the temptation to adopt the newest, most talked-about tool — proven tools ship faster and break less.
