01
Microservices
Service APIs, integration points, and shared contracts that can evolve over time.

Clear backend work for real product needs.
A few areas I commonly work on: APIs, service communication, data access, payment flows, and practical product changes.

API Gateway
Routing, authentication, rate limits, and request handling at the edge.
03
Payment Integrations
Checkout flows, webhooks, transaction updates, and provider APIs.
