About
With 13+ years of hands-on experience, I specialize in frontend-heavy full-stack delivery using React and Next.js, while building reliable backend services with Java Spring Boot and Node.js. I focus on performance, accessibility, and developer experience while keeping security and compliance front and center.
Here's a glimpse of my arsenal:
- Front-End Architecture: React, Next.js, React Native, TypeScript, Redux Toolkit, React Hook Form, Zod
- Back-End Systems: Java Spring Boot, Node.js, NestJS, Express, REST APIs
- Cloud + DevOps: AWS (Lambda, S3, DynamoDB), Azure DevOps, Docker, Kubernetes
- AI + LLM: Azure OpenAI, Generative AI, prompt workflows
- Data + Messaging: PostgreSQL, MySQL, MongoDB, Kafka, RabbitMQ
- Quality + Testing: Jest, React Testing Library, Playwright, Cypress, Selenium
Beyond the code, I'm a proactive collaborator and mentor who enjoys solving complex problems and shipping high-quality user experiences. I'm always exploring new technologies in Generative AI and modern UI systems to keep teams and products ahead.
Let's collaborate! I'm eager to hear about your next digital challenge and how I can help you transform it into a reality.
