API Integration

I connect business applications, IoT devices, and external services through REST APIs, MQTT messaging, OAuth2 flows, email, and notification-oriented integrations.

RESTful contracts

Backend endpoints and service boundaries designed for predictable data exchange.

Real-time events

MQTT communication for device status, sensor data, and operational workflows.

What This Covers

API boundaries

REST API implementation for application-to-application workflows and delivery platform synchronization.

IoT messaging

MQTT-based communication for smart locker devices, sensor events, and real-time validation logic.

External services

OAuth2, Dropbox, email, SMS, and notification integrations from CV-backed enterprise and IoT work.

Operational reliability

Integration logic shaped around debuggability, message handling, and long-running system stability.
