Integrations that survive real traffic
Third-party APIs fail, rate-limit and change. Integrations I build assume that: idempotent handlers, exponential backoff, dead-letter queues and replay tooling for the messages that still failed.
Every integration exposes its health, so a broken sync is discovered by an alert rather than by a customer.
Common connections
Payment providers (Stripe, Razorpay). CRMs (Salesforce, HubSpot, custom). Email and messaging platforms (SendGrid, Twilio, WhatsApp). Accounting systems (Tally, Zoho Books). Logistics and inventory APIs.
Internal legacy services reached over SFTP, SOAP or custom protocols where necessary.
What you get
A tested integration with error handling, retry logic and monitoring. Documentation for the next developer. Alerting on failure thresholds so issues are caught before customers notice.
Data migrations with dry runs, validation reports and rollback plans.
Frequently asked questions
Can you work with an undocumented API?
Often yes, by inspecting live traffic and building a tested client against observed behaviour.
How do we monitor the integrations?
Each integration reports status, throughput and errors to a dashboard, with alerts on failure thresholds.
Do you handle data migrations too?
Yes, including dry runs, validation reports and rollback plans.
