iOS Engineer specializing in VoIP, smart-property products and Odoo-connected mobile operations.

I currently build Majordom, a multi-brand application for residential property services. My previous work includes Cetmix Messenger and an Odoo-integrated courier application.

I also maintain CallWaveKit, an open-source incoming SIP SDK for iOS intercoms built with CallKit, PushKit and PJSIP.

A server-neutral SDK that helps iOS applications handle reliable incoming SIP calls without adopting a full softphone stack.

• CallKit and PushKit coordination, including push-to-INVITE race handling
• SIP registration, incoming audio calls, hold, mute and DTMF
• TLS, SRTP, ICE/STUN/TURN and IPv4/IPv6 connectivity
• Audio-route handling, call diagnostics and RTP statistics
• Swift Package Manager, CocoaPods and async/await APIs

I develop features for intercom calls and access control, video surveillance, smart devices, payments, service requests and resident communication. My work focuses on VoIP reliability, CallKit and PushKit integration, application stability, testing and release automation.

I worked on an iOS messenger connected to Odoo, bringing mobile communication into existing business workflows.

I developed an Odoo-connected iOS application that moved courier workflows from the ERP system to mobile devices.
