Most operational inefficiency in a growing company is not caused by any single system being bad. It is caused by systems not talking to each other — so someone exports a report from one, reformats it, and pastes it into another, every week, forever.
We do two related things: build APIs that other systems consume reliably, and carry out the integration work that removes manual data movement between the tools you already run.
Designing an API properly
An API is a contract, and once third parties depend on it, breaking it is expensive. We design for that reality: consistent resource naming, predictable pagination and filtering, meaningful HTTP status codes, and error responses carrying a machine-readable code alongside a human-readable message.
Versioning is planned from the first release rather than improvised at the first breaking change. Authentication uses OAuth 2.0 or signed tokens with scoped permissions, and every endpoint is rate limited with the limit and reset window exposed in response headers so consumers can behave correctly.
Documentation that stays accurate
We generate an OpenAPI specification from the implementation, so the documentation cannot silently drift from actual behaviour. Alongside it you get a browsable reference with authenticated request examples, a sandbox environment with realistic seeded data, and a Postman collection.
Integration work
Integrations fail in ways that first-time implementations rarely anticipate: the remote service times out, returns a malformed payload, rate limits you at the worst possible moment, or accepts a request and processes it twice. We build for those cases specifically — idempotency keys so retries cannot duplicate records, exponential backoff, dead-letter queues for messages that cannot be processed, and alerting when a sync falls behind.
Common work includes Tally and Zoho Books for accounting, Salesforce and HubSpot for CRM, Shiprocket and Delhivery for logistics, Razorpay and Stripe for payments, and WhatsApp Business for customer messaging.
Legacy and undocumented systems
Not every system offers a usable API. We regularly integrate with SOAP services, fixed-width file drops over SFTP, direct database reads against a legacy ERP, and vendor systems whose documentation no longer matches reality. Where no interface exists, we build an adapter layer that isolates the mess behind a clean internal contract.
