Hey, I'm Alex.

I'm an R&D Software Engineer specializing in Backend Engineering, Data Engineering, and Network Operations Tools

I build backend systems, data ingestion pipelines, analytics APIs, and internal network monitoring tools for telecommunications operations using Django REST Framework, PostgreSQL, Redis, Celery, Kafka, Flink, Linux automation, and production-style API practices.

Alexander John Camaddo | Full-Stack Developer

About.

I am Alexander John M. Camaddo, an R&D Software Engineer with a backend and data engineering focus.

My current work at Converge ICT Solutions Inc. involves building internal systems for telecom network operations. I work on backend APIs, ingestion pipelines, analytics services, and operational automation that help convert raw infrastructure, vendor, and network data into usable systems for monitoring, reporting, troubleshooting, and internal dashboards.

I have contributed to systems involving BRAS CGNAT logging, OLT/LCP/BRAS network health dashboards, OLT latency monitoring, Speedtest analytics, OLT port utilization, Ookla Data Lake ingestion, Downdetector reporting, LCP ONU testing workflows, and inventory synchronization.

Technically, I work most often with Python, Django REST Framework, PostgreSQL, Redis, Celery, Linux, Bash, OpenAPI, Postman, Pytest, Kafka, Flink, Kafka Connect, Filebeat, MinIO/S3, Parquet, and Snappy. I care about building systems that are reliable, testable, documented, and safe to operate in production-like environments.

Before Converge, I built full-stack applications at the SPCF ICT Development Unit, where I worked on school management systems, healthcare systems, mobile applications, booking systems, CMS features, and blockchain-related prototypes.
