About

software, mobile app development, website development, frontend, backend, react native, react, nextjs, nestjs, typescript, javascript, ios, android, xcode, android studio

I don't just write code; I design and deliver complete, production-ready systems. With an architectural mindset, I own the entire development lifecycle from the initial conceptual design to scalable production deployment.

With 10+ years of professional experience, I bridge the gap between high-performance frontend/mobile experiences and robust backend infrastructures. My focus is on building sustainable software that is scalable, maintainable, and secure from day one.

Frontend & Mobile: Expert-level React.js, React Native, JavaScript, and TypeScript.

Backend & DevOps: Scalable architectures using Nest.js, PostgreSQL, and Docker.

System Design: RESTful APIs, Role-Based Access Control (RBAC), and optimized database schemas.

The Next Frontier: Agentic AI. I am currently diving deep into Agentic AI and AutoGen, focusing on building autonomous, goal-driven AI systems.

For me, solving complex architectural and technical problems is more than a job — it’s a genuine passion. I enjoy turning abstract ideas into clear, scalable, and production-ready digital products that create real impact.
