What I Do



I design and deliver scalable mobile applications from concept to production across iOS and Android. With hands-on experience integrating complex systems—such as e-commerce platforms, subscription services, and real-time features—I focus on performance, reliability, and seamless user experience. I build architectures that support growth, optimize operational efficiency, and align closely with business objectives, ensuring long-term product success.

I build high-performance, scalable web applications — from modern landing pages and SaaS admin portals to full-scale platforms. With strong experience in Next.js and system architecture, I focus on SEO, performance optimization, and seamless user experiences. I develop solutions that handle real-world traffic, integrate with complex backend services, and support business growth through reliable, maintainable code and clean UI/UX.


I design and build robust, scalable backend systems that power high-traffic applications. With experience in NestJS and distributed architectures, I develop secure APIs, optimize database performance, and implement reliable integrations across services such as payments, messaging, and third-party platforms. I focus on maintainability, fault tolerance, and system efficiency—ensuring your platform can scale smoothly while handling complex business logic and real-world workloads.

I have hands-on experience integrating services like Mailgun and Twilio (SMS/email), configuring
