About this gig
Are you looking for a reliable full-stack developer who builds web applications with security as a first-class concern, not an afterthought? I've got you covered.
I specialize in building fast, scalable, and secure web applications using:
- Frontend: React.js, Next.js, HTML/CSS, Tailwind
- Backend: Java, Spring Boot, Spring Security
- Database: PostgreSQL, MySQL, MongoDB
- Security: JWT and OAuth2 authentication, role-based access control (RBAC), password encryption (BCrypt), CSRF and CORS protection, input validation, protection against common OWASP Top 10 vulnerabilities (SQL injection, XSS, broken auth)
- Other: REST APIs, third-party integrations, deployment (AWS, Vercel, DigitalOcean)
What I offer:
Custom full-stack web applications from scratch
Secure authentication and authorization systems (login, roles, permissions)
Bug fixes and security hardening on existing apps
API development with proper access control
Responsive, mobile-first design
Clean, well-documented, maintainable code
Deployment and basic DevOps setup
