Services

Development services, delivered by one senior developer

Full-stack web development, SaaS applications, AI and LLM integrations, CRM and ERP systems, APIs, and the maintenance and support that keep them running. Every project is scoped, built and supported by Gurwinder Singh directly.

What I offer

Build, integrate, maintain

New products, AI features, business systems, and the long-term care of applications already in production.

Technology

A stack chosen for how long it has to last

React, Next.js, Node.js, TypeScript, PostgreSQL, MongoDB, Prisma, AWS and AI integrations, chosen for maintainability, not novelty. Your system should still be supportable in five years, by any competent developer.

Let's talk

Have a project in mind? Let's talk it through

Tell me what you're building or what isn't working. You'll get an honest view of the right approach, a written scope, and a straight answer if custom software isn't what you need.

What happens next
  1. Step 1: Tell me what you're building, on WhatsApp or with the contact form.
  2. Step 2: A short call with me to understand the requirements. No sales pitch.
  3. Step 3: A written scope and estimate you can act on, with no obligation.
