Senior fullstack engineer building scalable enterprise SaaS with React, Node, microservices, and cloud-native architectures.
What I'm looking for
I’m a Senior Fullstack Engineer with 10+ years of experience building enterprise SaaS platforms, combining RESTful APIs, React.js/Next.js, microservices, and cloud-native architectures to deliver secure, highly available web systems.
I modernize legacy applications into scalable, maintainable ecosystems—leading frontend architecture blueprints, enforcing TypeScript standards, and improving performance with bundle analysis, tree-shaking strategies, runtime profiling, and Core Web Vitals optimization.
Across multi-tenant environments, I design tenant isolation and security, implement event-driven patterns and CI/CD pipelines, and strengthen observability with Application Insights, Grafana, Prometheus, Datadog, Sentry, and structured logging/distributed tracing.
I bring a hands-on, quality-first mindset: test-driven development (Jest, Cypress, xUnit/NUnit where applicable), accessible UI/UX (ADA/WCAG), and mentorship that aligns cross-team UI/UX and backend contracts for reliable releases.
