Backend Development
Scalable, secure backend systems with Node.js and Python. We build high-performance APIs, databases, and server infrastructure that handle millions of requests with reliability and efficiency.
What We Deliver
For each engagement we focus on measurable outcomes: product-market fit, reliable models and systems, and an engineering setup for safe, maintainable production. Below are the core features and capabilities we implement as part of this service.
Node.js development (Express, NestJS, Fastify)
Python development (FastAPI, Django, Flask)
RESTful & GraphQL API design and implementation
Database design: PostgreSQL, MongoDB, MySQL, Redis
Authentication & authorization (OAuth 2.0, JWT, RBAC)
Microservices architecture with Docker and Kubernetes
Real-time systems (WebSocket, Socket.io, message queues)
Payment gateway integration (Stripe, PayPal, Razorpay)
Third-party API integration and webhook management
Load balancing, caching strategies, and performance tuning
Our Approach
- 1
Discovery & Feasibility
We run a short discovery to validate data availability, define success metrics and create a technical feasibility plan with a clear MVP scope.
- 2
Prototype & Validation
Rapid prototyping to validate model quality and integration assumptions. We include human-in-the-loop evaluation and benchmarks.
- 3
Productionization
Harden the best models into reproducible pipelines, add monitoring, CI/CD, and optimize for latency and cost (edge or cloud deployment as required).
- 4
Scale & Operate
Ongoing improvements, retraining pipelines, A/B testing and performance SLAs.

Frequently Asked Questions
What backend technologies do you specialize in?
We specialize in Node.js (Express, NestJS) and Python (FastAPI, Django, Flask). We choose the technology based on your project requirements, team expertise, and scalability needs.
How do you ensure API security?
We implement authentication (JWT, OAuth 2.0), authorization (RBAC), rate limiting, input validation, SQL injection prevention, CORS configuration, HTTPS encryption, and regular security audits to keep your APIs secure.
Can you work with our existing database?
Yes! We have experience with PostgreSQL, MySQL, MongoDB, Redis, and other databases. We can integrate with your existing database, optimize queries, or help migrate to a better solution if needed.
Do you provide API documentation?
Absolutely! We provide comprehensive API documentation using tools like Swagger/OpenAPI, Postman collections, and detailed endpoint descriptions including request/response examples, authentication requirements, and error codes.
