Technical Experience

I have designed and implemented enterprise authentication and authorization systems for web applications, including Single Sign-On (SSO) solutions leveraging the Microsoft Federation framework and SAML standards, following established Identity Provider (IdP) and Service Provider (SP) architectural models. My expertise includes OAuth 2.0, OpenID Connect, JWT-based security, and multi-factor authentication across large-scale enterprise environments.

I have designed and optimized enterprise-scale database architectures using relational and NoSQL platforms, including PostgreSQL, MySQL, Microsoft SQL Server, and MongoDB. My work includes database migration planning, replication and high-availability strategies, and performance tuning for high-traffic applications managing millions of records, across domains such as healthcare, real estate, and job marketplaces.

Implemented security best practices including OWASP guidelines, encryption standards, and secure coding practices. Experience with compliance frameworks such as SOC 2, HIPAA, and GDPR. Conducted security audits and vulnerability assessments to ensure application integrity.

Led and mentored development teams of various sizes, from small startups to enterprise organizations. Conducted code reviews, established coding standards, and implemented agile methodologies. Facilitated knowledge sharing sessions and helped junior developers grow in their careers.

Extensive experience in building complete web applications from frontend to backend. Skilled in React, Next.js, Angular, and Vue.js for frontend development, combined with Node.js, .NET Core, Python, and Java for backend services. Built scalable RESTful APIs and GraphQL services serving millions of requests.

I have architected and developed scalable RESTful APIs for enterprise-level application integrations, supporting high availability and secure, granular control of business data. All APIs are governed by a robust versioning strategy to ensure ongoing access, backward compatibility, and incremental expansion of business capabilities.

Expert in identifying and resolving performance bottlenecks across the entire stack. Implemented caching strategies, lazy loading, code splitting, and database query optimization. Achieved significant improvements in page load times and server response rates for production applications.
