I'm building and maintaining real-time industrial IoT telemetry pipelines at AS3, from MQTT data collection to production dashboards for water, gas, and energy monitoring.
I've architected Python MQTT brokers for LoRaWAN and 4G devices, migrated legacy OpenVZ/Debian infrastructure to KVM/Ubuntu for 45+ IoT devices, and containerized a monolithic system to improve deployment portability and traceability.
Across freelance projects, I've delivered payment gateway APIs, fleet tracking, financial notification services, database integrations, and WhatsApp AI assistants using Java, React, Node.js, Python, AWS, Docker, and PostgreSQL.
