Jun 2023 - Jan 2026 • 2 yrs 7 mos
Worked with Titansoft on building and connecting their internal systems to improve how they handle leads, customer communication, and day-to-day operations. Built a React Native mobile app for both iOS and Android, adding AI features like chat, voice interaction, and simple recommendation logic to improve user experience. Set up and customized their CRM, including pipelines, lead tracking, and automated follow-ups across email and SMS so leads didn’t go cold. Handled messaging automation across WhatsApp, Facebook Messenger, Instagram, and Telegram to make customer communication more consistent and less manual. Also set up their call system using open-source VoIP tools, and connected everything together using n8n, Make, and Zapier so their tools could actually work as one system. On top of that, developed supporting backend services and web apps where needed, including real-time features and payment integrations. Results: Reduced lead response time to under a minute Cut call system costs by more than half Left them with a setup they can manage without depending on a developer
