I’m a senior mobile and frontend engineer with over 7 years of experience building real-world applications that people actually use. I’ve worked across a wide range of products — from early-stage startups to large-scale systems — and across many domains including eCommerce, SaaS platforms, fintech, security products, IoT-related apps, and consumer mobile applications. Over the years, I’ve delivered 40+ production apps and worked on everything from MVPs to complex enterprise platforms. My core strength is in mobile and frontend engineering, especially React Native and React, but my work goes far beyond one framework or one platform. I’ve built cross-platform apps, native iOS and Android applications, and hybrid systems, and I regularly work on architecture decisions, performance optimization, and long-term maintainability of codebases. Core technologies I work with: - React Native, React - Flutter, Ionic, Cordova, Capacitor - Native iOS (Swift) and Android (Kotlin/Java) - Node.js, REST APIs, SQL, Firebase - Modern frontend and mobile architectures I’m comfortable working at both the implementation level and the architectural level — whether that means writing clean, maintainable code, designing scalable systems, or helping teams make the right technical decisions for long-term growth. Clients usually come to me when they need someone who can: - build things properly, not just quickly - think in systems, not just features - improve performance, stability, and structure - work independently and take ownership I care a lot about code quality, performance, and building products that are easy to maintain and scale over time. If you’re looking for a senior engineer who’s reliable, practical, and experienced across many types of products and industries, I’d be happy to talk about your project.

I build AI Automation systems for real estate teams. Most Real Estate developers, investors, brokerages, and property teams are still running too much of the business manually. That is exactly why clients hire me. I help real estate teams build better systems around AI Agent Development, CRM Automation, Workflow Automation, Lead Generation, Chatbot Development, API Integration, Data Integration, Task Automation, and Business Process Automation. That can mean an AI agent that qualifies leads, a CRM workflow that updates itself, a dashboard that shows what is happening, or an automation system built with tools like n8n, Make, Zapier, OpenAI, Airtable, Python, and custom APIs. The main goal is simple: Build an AI Automation system that actually works in your day-to-day business. A system that helps you and your team save time, money, move faster, follow up better, and most importantly, perform better! I’ve already earned $200K+ on Upwork, completed 100+ jobs with amazing client feedback, and worked 9,000+ hours. I also have a 100% Job Success Score and Top Rated Plus status, so I understand how to build systems that clients can trust, not just test for a few days and abandon. Let’s chat, I am open to more work!
