How to Hire a Full-Stack Developer for Your Website or Business Application

A full-stack developer can build both the frontend (what users see) and backend (logic, data, and integrations) of your website or business application. This guide helps South African businesses evaluate and hire the right person or partner.

What Does a Full-Stack Developer Do?

Frontend: User interfaces with HTML, CSS, JavaScript/TypeScript, and frameworks like React.
Backend: APIs, authentication, business logic, and server-side code.
Database: Data modeling with SQL or NoSQL databases.
Integration: Payments, email, SMS, WhatsApp, CRMs, and third-party APIs.
Deployment: Hosting, environments, and production readiness.
Maintenance: Security updates, bug fixes, and improvements.

When Do You Need a Full-Stack Developer?

Consider hiring a full-stack developer if you're building a custom web application, SaaS platform, marketplace, or need complex integrations. For simple brochure sites, a focused developer may suffice.

Freelance vs Agency: Which Is Better?

Freelance: Often more flexible and cost-effective for well-scoped projects; requires clear communication.
Agency: Provides broader skills and coverage, but may be overkill for smaller projects.

How to Evaluate Candidates

Portfolio: Look for live projects similar to what you need.
Technical fit: Ask about React, TypeScript, APIs, databases, and deployment.
Problem-solving: Give a small, realistic scenario and discuss their approach.
Communication: Can they explain technical concepts clearly?
Documentation: Do they document code and handover well?

Key Questions to Ask

Can you walk me through a similar project you built?
How would you structure this specific feature?
How will you handle authentication, data, and security?
Who owns the source code and how is it delivered?
How do you handle testing and deployment?

Pragmatic Advice

Write a clear brief: Goals, users, must-have features, and success criteria.
Start small: Consider a discovery phase or MVP first.
Protect ownership: Ensure source code and credentials are handed over.
Plan for support: Discuss post-launch maintenance upfront.
Prioritize clarity: Avoid vague requests like "build an app" without details.
