Why Businesses Choose Us for Backend Development

Proven under real load

We built the TypeScript microservices behind Tooth Fairy, a UK health-regulated platform, talking over gRPC with MongoDB and Redis. Backend that holds up under real traffic and compliance is not new to us.

The right architecture, not the trendy one

Monolith or microservices, REST or gRPC, SQL or document store: we choose based on your product and team, not on what is fashionable. Most products do not need microservices, and we will tell you so.

Secure and observable by default

Auth, encryption, rate limiting, and structured logging are built in from the start. When something breaks at 2am, you can see why, because the monitoring was wired on day one.

Frequently Asked Questions

The server side of your product: the APIs your app or website talks to, the database that stores your data, the integrations with third-party services, and the authentication, security, and infrastructure that keep it running. We build and maintain that layer so your frontend or mobile team has a reliable engine to build on.
Mostly Node.js with TypeScript, Laravel (PHP), and Python (Django, FastAPI). We pick the one that fits your product, your team, and where you want to be in three years, rather than forcing every project through a single framework.
Yes. A common request is a backend-for-frontend: you have a React, Next.js, or mobile app and need someone to design and build the API, database, and integrations behind it. We can also take over and stabilise an existing backend.
REST is the sensible default for most APIs. GraphQL fits when clients need flexible, shaped queries across many entities. gRPC is best for fast, strongly-typed service-to-service communication, which is why we used it between the Tooth Fairy microservices. We recommend based on your real use case.
Yes. Authentication, role-based access, encryption in transit and at rest, rate limiting, and structured logging are part of the build. For scale we use caching with Redis, containerised deploys, and independently scalable services where the load profile justifies it.
Yes. We work with clients globally. All communication happens via WhatsApp, video calls, and email. We have successfully delivered projects for businesses in multiple time zones and geography has never been a barrier.
Every project includes 30 days of free post-launch support. Any bugs, browser issues, or content corrections are fixed at no extra cost. After 30 days, we offer affordable monthly maintenance packages starting from $60/month.
Yes. We provide proper invoices in USD for international clients. Indian clients receive GST-compliant invoices. All payment methods supported including international bank transfer, PayPal, and Wise.
