Backend Engineer on a cyber threat intelligence platform integrating OSINT APIs and optimizing MySQL queries.

Indonesia

Message

On a cyber threat intelligence and OSINT platform for a Confidential Client, I integrate services including WhoisXML, Shodan, DeHashed, and Wayback Machine to support domain, IP, and data breach investigations. I also built automated APK security scanning endpoints using MobSF.

I optimized MySQL queries handling nested JSON data and configured secure proxy routing over OpenVPN tunnels. I also implemented OTP workflows and maintained Swagger/OpenAPI documentation for 40+ controller endpoints.

At PT. SAI (Sarana Amal Indonesia), I developed a white-label application architecture and integrated Midtrans payments and Google OAuth. Across other roles, I’ve worked on web, mobile, and enterprise platforms, including a government service app for Indonesia's new capital city.
