I've spent the last 5+ years as a full-stack engineer helping startups and businesses turn ideas into working products from native mobile apps to enterprise-grade telephony systems handling thousands of daily calls. What I bring to the table: Mobile Development I've shipped 50+ native Android (Kotlin/Java) and iOS (Swift/SwiftUI) apps, plus cross-platform builds in Flutter and React Native, across fintech, e-commerce, SaaS, and telecom. I handle the full cycle: architecture, development, and App Store/Play Store submission so you're not left figuring out deployment on your own. Full-Stack Web Development Node.js, NestJS, Python (FastAPI/Django) on the backend; React, Next.js, and TypeScript on the front. I build on AWS with real database design (PostgreSQL, MongoDB), not just quick fixes systems built to scale. AI & Automation (n8n) I've deployed 30+ production n8n workflows with zero downtime, including AI voice agents for cold calling, SDR support, and inbound automation using OpenAI and Anthropic APIs. This is where most freelancers stop at "connecting a few nodes" I build automations that survive real production traffic. VoIP & Telephony Infrastructure This is my specialty edge: Asterisk, FreePBX, and 3CX deployment, SIP/WebRTC configuration, and custom softphone apps (Linphone SDK). If you need a calling system that actually holds up under load, this is where I've spent years solving exactly that problem. Why work with me I don't just deliver code I deliver systems that work in production, under real traffic, with real users. I communicate clearly, scope honestly, and I'm not satisfied until what I build actually solves your problem. Let's build something that works.
