## About

Telecom QA specialist with 11 years of end\-to\-end testing experience at Plintron, a global MVNO enabler operating across 55\+ countries\. I have tested mission\-critical telecom systems across the full stack — from API gateways and billing engines to protocol\-level testing on SIP, Diameter, and SS7\. My work spans products that handle real\-time charging, voice media, SMS routing, and third\-party top\-up transactions at scale\. I bring both the technical depth to design test strategies for complex protocol systems and the leadership to drive quality across releases\. What I test: • API gateway testing \(REST/XML/JSON\) — ETU Electronic Top\-Up platform • SIP protocol testing — IVR, voicemail, pre\-call announcements, VVMS \(Plintron PowerMedia\) • Diameter protocol — SCap, Ro interface, calls & SMS \(SCG application\) • SS7 protocol — SCPNG application using MGTS tool • OCS core billing — RRBs, calls, and SMS \(core charging system\) How I test: • Automation: Playwright, Robot Framework • Performance: JMeter, SIPp, Seagull scenarios • Manual, protocol\-level, API, and load testing • Auto deployment pipelines and CI\-aware testing 11 years in one telecom platform means I don’t just find bugs — I understand the system well enough to prevent them\. How I work: I automate what can be automated \(Playwright, Robot Framework, MGTS\), load\-test what needs to perform under pressure \(JMeter, SIPp, Seagull\), and flag risk before it becomes a defect\. I’ve cut regression cycle time by 40% and reduced deployment validation effort by 60% through pipeline automation\. 📍 Chennai \| Open to Onsite · Hybrid · Remote
