What I'm looking for

I’m looking for a team where I can build secure multi-tenant SaaS and high-performance web apps using Next.js, SpringBoot, and MEAN Stack—while leveraging SEO, UI/UX, and API best practices to ship products that scale.

I’m a results-driven Full-Stack Web Developer with 3+ years architecting scalable web applications and SaaS platforms using MEAN Stack, SpringBoot, Next.js, and Flutter. I specialize in RBAC implementation, multi-tenant architecture, and API development with Swagger documentation—turning complex requirements into secure, maintainable systems.

At Digitalis SA, I architected a multi-tenant SaaS with data isolation for 50+ tenant organizations, delivered real-time admin dashboards (improving decision-making speed by 40%), and built cross-platform mobile apps with Flutter and Riverpod (reducing development time by 25%). I also reduced application load times by 30% and grew organic traffic through SEO optimization, and my work on responsive UI with TailwindCSS, Shadcn, Bootstrap, and WCAG accessibility has helped teams ship faster and with better user experience.
