Freelancer Profile

About

build practical software for sales automation, customer management, and business communications. My experience includes CRM platforms, Electron desktop apps, Android applications, SIP telephony, AI voice agents, speech recognition, REST APIs, and data automation. I have developed Bulatkin Leads, a CRM platform for outbound sales with campaigns, user roles, customer profiles, call scripts, call outcomes, reporting, and data synchronization. I also built companion apps for Android, Windows, and macOS. My work includes direct SIP calling, RTP audio, call recording, microphone and speaker support, large CSV imports, automatic lead assignment, and reliable CRM integrations. I have also developed local AI voice features using speech recognition and text-to-speech, without requiring audio to be sent to external cloud services. I work with JavaScript, Node.js, TypeScript, Electron, Java, Kotlin, Swift, SwiftUI, SQLite, Docker, SIP/RTP, WebRTC, Sherpa-ONNX, Vosk, and Playwright. I focus on clear communication, practical solutions, and reliable results. I can take a project from an idea or existing codebase to a working, tested application.
