What I'm looking for

I’m looking for full-time remote work with flexible hours, where I can build scalable, secure APIs and responsive web/mobile products, collaborate in Agile teams, and continuously improve performance, CI/CD, and system reliability.

I’m a Full Stack Software Engineer and CTO - Full Stack Engineer who builds production-ready web and mobile systems for remote teams. I focus on scalable architectures, secure REST APIs, and clean workflows that ship reliably.

With experience across React, React Native, NestJS, TypeScript, and PostgreSQL, I’ve developed features like role-based authentication, offline-first mobile synchronization, and optimized database performance using Prisma ORM. I also bring strong backend depth through Python (FastAPI) and AI work with TensorFlow for predictive analytics and inventory recommendations.
