What I'm looking for

I seek roles where I lead product-focused engineering teams, build scalable SaaS/mobile solutions, mentor engineers, and work in collaborative Agile environments that emphasize performance, reliability, and AI-driven features.

I am a seasoned Full Stack Developer and Technical Lead with five years of hands-on experience delivering web and mobile applications that drive business growth in dynamic tech environments.

I specialize in frontend development with React, TypeScript, React Native and related technologies, and backend development using Node.js and MongoDB, building end-to-end solutions from concept to deployment.

I've led teams and projects that improved performance and scalability—reducing load times by up to 40%, increasing e-commerce sales by 25%, and cutting administrative overhead and management time significantly through optimized dashboards and automation.

I prioritize clean, reusable code, mentorship, and Agile practices, and I integrate modern tools including CI/CD, Docker, cloud platforms, and AI/LLM tooling to deliver secure, high-performing SaaS and mobile experiences.
