APIs and backends that don't break.
The invisible architecture that powers everything. We build APIs, backend services, and data pipelines with Node.js, TypeScript, and PostgreSQL — designed for reliability, speed, and maintainability.
Backend systems for every layer.
REST & GraphQL APIs
Well-documented, versioned APIs with proper authentication, rate limiting, pagination, and error handling. Designed for consumption by web, mobile, and third-party clients.
Database Architecture
PostgreSQL schema design, migrations, indexing, and query optimization. Proper normalization for complex data relationships. Read replicas for scale.
Third-Party Integrations
Payment gateways, CRMs, ERPs, shipping APIs, email providers, and any system with an API. We handle authentication, error recovery, and data mapping.
Background Jobs & Queues
Email sending, report generation, data processing, and long-running tasks. BullMQ, Redis-backed queues with retry logic and dead letter handling.
Webhook Infrastructure
Receive, validate, and process webhooks from any service. Idempotent processing, retry queues, and event logging for reliable event-driven architecture.
Authentication & Authorization
JWT, OAuth 2.0, SSO, API keys, and role-based access control. Multi-tenant isolation, audit logging, and security best practices baked in.
Proven tools for production systems.
Node.js with TypeScript strict mode. Type-safe from request to response.
PostgreSQL for relational data. Redis for caching, sessions, and queues.
Prisma or Drizzle for type-safe database access with migrations and introspection.
tRPC for type-safe APIs. REST with OpenAPI spec. GraphQL when needed.
Clerk, NextAuth, custom JWT. OAuth 2.0, RBAC, multi-tenant isolation.
BullMQ with Redis. Retry logic, dead letter queues, priority scheduling.
Docker, AWS/Vercel, GitHub Actions. Auto-scaling, health checks, blue-green deploys.
Sentry for errors. Datadog or custom metrics. Uptime monitoring. Log aggregation.
How much does API or backend development cost?
A standalone REST/GraphQL API for a typical product runs ₹3L–₹10L depending on the number of endpoints, integrations, and auth complexity. A full backend with database design, queues, and third-party integrations is usually ₹8L–₹25L. We scope it precisely on a free call before quoting.
Can you build an API for an existing frontend or mobile app?
Yes — this is common. We design the API contract around what your client apps need, document it (OpenAPI/GraphQL schema), and deliver it with auth, rate limiting, and versioning so your frontend and mobile teams can integrate cleanly.
Do you work with our existing database and infrastructure?
We can. We'll audit your current schema, queries, and hosting first, then either build on top of it or recommend targeted changes. We won't force a rewrite if your foundation is sound.
How do you handle third-party integrations like payments or CRMs?
We build integrations with proper error recovery, idempotent processing, and retry queues so a flaky third-party API never corrupts your data or loses an event. Payment gateways, ERPs, shipping, email — if it has an API, we can integrate it.
Will the backend scale as we grow?
We design for it from day one — proper indexing, read replicas where needed, background queues for heavy work, and caching with Redis. We also add monitoring and error tracking so you see problems before your users do.
Need a solid backend?
Whether it's a new API, a system integration, or replacing a fragile backend — let's talk about the right architecture.
