What I'm looking for

I seek roles where I can lead engineering efforts, build scalable web/mobile products, mentor developers, and work in collaborative, Agile teams focused on growth and impact.

I am a full-stack software and mobile app developer with over four years of hands-on experience building production-grade applications using React, Next.js, React Native, Django, Node.js, and related technologies.

I've led engineering teams and delivered multiple projects, improving deployment velocity and reducing post-deployment bugs through CI/CD, code reviews, and mentoring. I manage cloud infrastructure on DigitalOcean and maintain high uptime and scalable architectures.

My work spans web and mobile marketplaces, internal tools, and community-focused apps where I optimized databases (PostgreSQL, MySQL, MongoDB) and implemented secure RESTful APIs. I also drive requirements gathering, agile delivery, and cross-functional collaboration to ensure solutions meet business needs.

I am committed to continuous improvement, knowledge sharing, and building impactful products that scale while maintaining strong communication and team-focused leadership.
