About

Software Developer with hands-on experience in high-volume charging and billing platforms. I work on systems where accuracy, financial correctness and end-to-end validation directly impact business revenue and customer experience. I focus on: Real-time transaction processing Charging / rating / billing logic SQL-driven validation across SIT/UAT to prevent revenue leakage Improving performance of long-running backend workloads (e.g., daemon optimization) Ensuring smooth deployment and operational stability across environments How I think 🤔 ? I enjoy understanding not just how systems work, but why they are designed that way — the business logic behind transactions, the guardrails that prevent financial loss, and the operational constraints that shape architecture decisions.
