What I'm looking for

I'm looking to build reliable, high-throughput backend and distributed data systems, while growing my practical AI/LLM engineering work in a collaborative remote environment.

I've built production data platforms at Reggali that ingest 1.2+ TB per day per telecom operator for SIM-traffic compliance and fraud detection. My binary-protocol parsing and encryption pipeline processes 500M+ records daily through NiFi, Kafka, MinIO, Hudi, Hive, Spark, and Flask.

At The Zeal, I built Java Spring Boot services for real-time financial systems, processing 5–6 TB of market data across 20+ global markets. At IT Max Global, I reduced a 900M-record dataset to 200M through data lifecycle management while supporting large-scale regulatory ingestion.

I work across REST APIs, microservices, stream processing, cloud deployments, observability, and security, and I can deliver full-stack products with React and Laravel. I'm also applying LLMs, RAG, AI agents, and AI-assisted development tools to practical engineering workflows.
