A2P monetization specialist and fraud prevention engineer at Infobip, with over a decade defending mobile operator revenue across APAC, MENA, and the Americas. Currently dual product champion for Voice Firewall and SMS Firewall penetration testing.
Both the hunter and the gamekeeper, simulating bypass attacks while building the defenses that stop them.
I'm a telecom monetization specialist with over a decade of experience protecting mobile operator revenue from fraud, grey routes, and bypass traffic. Based in Indonesia, I work at Infobip where I serve as a managed services engineer across A2P SMS and Voice Firewall deployments spanning APAC, MENA, and Latin America.
In 2025, I became Infobip's FCDX Voice Firewall Champion — and in 2026 added FR Injector Champion to that, making me the dual product champion across both voice and SMS fraud prevention platforms. As FR Injector Champion, I coordinate SS7/MAP penetration testing across 55 operator deployments to validate firewall effectiveness against real-world bypass techniques.
Alongside my telecom work, I've embraced AI-augmented engineering — shipping 4 production tools using Claude Code in 7 weeks with zero prior frontend experience, driving AI adoption enterprise-wide through documented workflows and 45 Confluence artifacts.
9 tools built with Claude Code across production, knowledge, and personal projects.
20+ MNO engagements across Southeast Asia, South Asia, the Middle East, the Caribbean, and Latin America.
Key responsibilities span traffic monitoring and leakage analysis, grey route detection and elimination, MSISDN range analysis, SIM box detection via CDR signals, and firewall optimization across complex multi-operator environments. As FCDX Champion, drove AI adoption from zero to documented enterprise-level workflows in 7 weeks. As FR Injector Champion, coordinating SS7/MAP penetration testing compliance across 55 deployments in 4 tiers across APAC and LATAM.
Operated carrier-grade infrastructure including Genie Networks scrubbing systems for DDoS mitigation, Layer 3 & 7 security, Juniper routing and switching, and cross-border BGP management. Built expertise in large-scale network operations, SLA compliance, and multi-service technical support before transitioning to telecom fraud prevention at Infobip.
Named FR Injector Champion for 2026, representing the Managed Services team as product advocate for Infobip's SMS Firewall penetration testing program. FR Injector validates firewall effectiveness by injecting manipulated SS7/MAP signaling packets (SRI, FSM-MT, TCAP) to simulate real-world bypass techniques across 55 operator deployments in 4 tiers: TOP6 and Tier 1 tested monthly, Tier 2 quarterly, and Tier 3 every 6 months. The role covers driving testing adoption across APAC and LATAM teams, coordinating with 17 engineers, tracking compliance via automated dashboards, and working directly with Product Development on firewall rule improvements. As part of the role, built the FR Injector Testing Adoption Tracker, an AI-powered web application providing real-time visibility into testing compliance, overdue networks, and team performance across all deployments. Holding this title alongside the FCDX Voice Firewall Champion role, making it a dual product champion position across both voice and SMS fraud prevention platforms.
Self-paced courses from Anthropic Academy covering Claude Code fundamentals, prompt engineering, tool use, and the Model Context Protocol (MCP). Tracks span AI Fluency, Product Training, and Developer Deep-Dives.
Named FCDX Champion starting Q4 2025, continuing through 2026. Shipped 4 AI-powered tools using Claude Code, logged 37+ hours of AI-driven development, and drove internal AI adoption to documented enterprise-level workflows across 45 Confluence artifacts within 7 weeks.

"You took over a demanding project in a relatively short time, and were able to adapt and make sure there are no setbacks. You also contributed a lot to development of FCDX. Your inputs since you took over the champion role made it easier for our PD and devs to know what to focus on. Taking into account the complexity of both, which is typically above the scope of your current role, you showed you have the will and potential to perform really well. Kudos to you for that!"
"You have become much more independent over the past year and a more reliable team member. You now have a solid understanding of the business and can effectively use the firewall tools. Despite the challenges, you've still performed well overall, especially in a key APAC deployment, which turned out to be a much better deal than we initially expected, despite it being your first live deployment. You've also had success using the FCDX module in a key MENA deployment. Keep up the good work, and continue to build on your strengths!"
