About me
Telecom software engineer in Dhaka — I build softswitch and PBX platforms for carriers by day, and have helped Fiverr clients with the same stack since 2018. I set up, fix and extend VoIP systems (FreeSWITCH, FusionPBX, Asterisk, Kamailio) and build WebRTC calling apps with React, SIP.js and Janus, backed by Java Spring Boot or Node.js. 36 orders, 5.0 rating, and I answer within the hour. Tell me the symptom or the goal and I'll tell you exactly what it takes.
