I architect telecom-scale backend systems where reliability is the product.

For the last 5 years, I have been working deeply on telecom platforms, charging systems, IMS/5G core flows, and Java-based distributed backends. Before that, I spent years in datacom and embedded systems, working with C, TCP/IP protocol stacks, application delivery controllers, switching/routing devices, DLNA platforms, OS internals, and processor-level fundamentals.

That systems foundation helps me design software from the protocol level up, with attention to performance, failure modes, observability, and 24×7 production behavior.

I am currently expanding this foundation into LLMs, deep learning, and agentic workflows. I also follow adjacent areas like quantum computing and quantum cryptography, with a focus on how these technologies can improve engineering productivity, security, and future network systems.
